Solar power generation bids in Tamilnadu with Payment support mechanism, LC and Rate contract 


Tamil Nadu has promised the solar power producers that it will pay the dues to them. The promise comes at a time the state electricity board owes a little over '1,000 crore to the wind energy sector. Today’s promise comes against the backdrop of Tamil Nadu’s plan to add around 3,000 Mw of solar power in three years.


While addressing the prospective bidders consultation meeting for 1,000 Mw state distribution company Tangedco ’s Managing Director K Gnanadesikan said, the main part of the project is that the payment is guaranteed and there will be a payment support mechanism as a letter of credit and the bid will be on the basis of a rate contract. It may be noted, Tamil Nadu has directed Tangedco to procure 1,000 Mw this year which will be supplied to high tension and LT industrial and commercial establishments.


The bid document will be issued within 10 days. The company, participating in the bid should have a minimum of '1 crore net worth per Mw.
The process will be decentralised so that anywhere in the state, the plant could be set up. “The government will not help with land acquisition for the project and there won’t be any subsidy for the 1,000 Mw and we will enter into a 20-year power purchase agreement,” said Gnanadesikan.


He added, while the purchase of power will commence in 2013-14, the distribution company will increase price 5 per cent every year up to 10 years.


While welcoming the government’s policy, which stipulates a target of 3,000 Mw capacity to be established by 2015-end, some of the solar majors have said the rate contract could have an impact on the quality of power produced.


They also said, evacuation is one of the key issues which the state government need to addressed, said C R Vijaya Kumar, EVP, MRO-TEK Ltd. For evacuation state electricity board will use the existing infrastructures, said Gnanadesikan.


Other industry representatives have also said, the government’s decision not to intervene in land acquisition will be another bottleneck and also no support from the Government on financial.


It may be noted, the state government has mandated for the HT industrial and commercial consumers to use solar power, under solar purchase obligation (SPO), which has been fixed as three per cent for 2013 and six per cent for 2014 out of their total energy consumption.


To meet this target the state government has been inviting solar power producers to set up plant in the state. source

This new process is likely to favour only large companies with large projects. 

The idea of increasing the bid amount by 5 % every year seems like an irrelevant and unwanted complication to the bidding process.

The idea of not utilising the REC mechanism and REC certificates to fulfil the Renewable Energy Obligation seems doesnt seem 

very far sighted. 

ThisTamil nadu solar  bid will clearly give green signal to chinese players to enter the Indian market in a big way.

The TN solar  bid will favour international and national companies that have deep pockets.

It will favour companies that have unsold solar panels to dump them in Tamilnadu.

This scheme will hurt all small and medium players wanting to break even in 5 to 7 years.

Opportunity for green power and brown power outside the Government's ambit will get

clear only after the bidding scene is over.

Evacuation will become a serious issue.

Capacity availability substation wise will not be available for some time to come, especially after the bidding process is over.

If TEDA and TANGEDCO are genuinely investor friendly, they should put up in their website the capcaity availability in each

substation. As well as the plans for building transmission lines for the next few years.

TANTRANSCO should put in their website, applications received for " flow study" and the results every month.

It should also mention the reasons for rejection, if any.

This will help investors plan their land acquisition.


Plans by the Government to set up districtwise  solar park must be made open

Transmission sector of TANTRANSCO consists of the following network Infrastructure:


  • EHT for a total length of 24,497 Kms.
  • A  total of 842 substations
  • 95 Substations in and around Chennai have been provided with SCADA and have been integrated into Chennai Distribution and control centre (DCC)
  • TANTRANSCO has one State Load Dispatch Centre at Chennai and 3 Sub LDCs at Chennai, Madurai and Erode. 


The transmission network expansion is aimed at evolving a national power grid to facilitate free flow of power across regional boundaries, raising the transmission voltage from 230 kV to 400 kV level. In order to evacuate bulk power from one region to another region, there is scope for enhancing the transmission capability to 765 KV level. Tamil Nadu Electricity Board has taken up the indigenous erection of 400 KV substations and lines. Establishment of 765 KV transmission lines is also under investigation.  


The Government of India has approved non discriminatory open access to the transmission system to all generators for injecting power and to any consumer to carry the power from the point of injection to his load. To augment the power supply, the Government of Tamil Nadu has also permitted third party sale of power produced by IPPs, CPPs & other private power producers through short term Intra-State open access to HT consumers within Tamil Nadu as it will provide an incentive to the generators within the State to produce to their full capacity.

Lands for solar power generation projects in  Tamilnadu - ideal lands ?


*1 mw of solar power plant will need about 5 acres of land

* Agriculutural lands are not allowed to put up a solar generation plant

* Non agricultural lands, non cultivable lands, barren lands, puramboke lands etc are ok

 * Rocky lands are not ideal for solar power generation

 * Many times soil testing of the land is done before deciding the feasibility

 * Ideally the land has to be very close to a substation. 11 kva, 33 kva, 66 kva, 132 kva, etc

 * For a 1 mw plant 11 kva is ok.

 * For each km the substation is away from your land, one has to incur about Rs 10 /12 lakhs for

   laying the transmission lines. Better than that is to buy up the land between your land and the


  * If there is some land between your land and the substation, there will ROW ie right of way


 * Download google earth and note the longitude and latitude of your land.

 * If you inform the above information a good Consultant will be able to assess the potential

    number of units that can be produced per annum


With the above information, it is possible to make the feasibility report for

the state nodal agencies, as well as detailed project report for the banks for solar

power generation business.

 Renewable Energy Certificate (REC) mechanism is a market based instrument to promote renewable energy and facilitate renewable purchase obligations (RPO). REC mechanism is aimed at addressing the mismatch between availability of RE resources in state and the requirement of the obligated entities to meet the renewable purchase obligation (RPO). Cost of electricity generation from renewable energy sources is classified as cost of electricity generation equivalent to conventional energy sources and the cost for environmental attributes.

RE generators will have two options

i) either to sell the renewable energy at preferential tariff

or ii) to sell electricity generation and environmental attributes associated with RE generations separately.

The environmental attributes can be exchanged in the form of Renewable Energy Certificates (REC). REC will be issued to the RE generators for 1 MWh of electricity injected into the grid from renewable energy sources. REC would be issued to RE generators only. Grid connected RE Technologies with minimum capacity of 250 KW and approved by MNRE would be eligible under this scheme. Central Agency would issue REC to RE generators for specified quantity of electricity injected into the grid. REC would be exchanged only in the CERC approved power exchanges. Price of electricity component of RE generation would be equivalent to the weighted average power purchase cost of the discom including short term power purchase but excluding renewable power purchase. REC would be exchanged within the forbearance price and floor price. This forbearance and floor price would be determined by CERC in consultation with Central agency and FOR from time to time. In case of default SERC may direct obligated entity to deposit into a separate fund to purchase the shortfall of REC at forbearance price.


 A Power Purchase agreement (PPA) in the field of solar power plant development is a twenty five (25) year buy back agreement done by the government with the developer. The tariff in case of a PPA is fixed for twenty five years or as defined in the PPA agreement.

Normally PPA based projects are allocated through a competitive bidding process where the developers interested to develop a solar power plant bid through a closed reverse bidding process to get the project. The developer who bids at the lowest tariff is allotted the project and so on. All expected capacities to be allocated through the PPA framework in the National Solar Mission as well as Rajasthan State Solar Policy will be through a competitive bidding process.

The REC mechanism comes with the risk of uncertainty of REC pricing. While there is a fixed REC floor price of `9,300 per REC (equivalent to 1MWh), there is some uncertainty on the pricing post 2017. RECs will be bought and sold in the market. But in the region of Rs 2k to 5k /MWh post 2017. 


(1 REC = 1MWh).


Every MWh of solar energy produced generates one REC. Central Electricity Regulatory Commission (CERC) has fixed a floor and forbearance price for the period 2012 to 2017 between which the RECs can be traded. India’s first solar REC project to start trading is a 2MW project in Madhya Pradesh developed by M&B Switchgears Limited.

India’s first solar REC project to start trading is a 2MW project in Madhya Pradesh developed by M&B
Switchgears Limited.

Registering a project under the REC scheme involves


2) Registration

Registration is done online. Accreditation and registration takes at least of 45 days. The issuance of RECs takes 15 days from the date of application. Application for accreditation must be submitted to the State Load Dispatch Centre (SLDC).
While considering any application for accreditation of RE generation project, the State Agency shall verify and ascertain availability of following 
a) Confirmation of ‘Availability of Land’ in possession for setting up generating station 

b) Power Evacuation Arrangement permission letter from the host State Transmission Utility or the concerned Distribution  Licensee, as the 
case may be 

c) Confirmation of Metering Arrangement and Metering Location 

d) Date of Commissioning of RE project for existing eligible RE Project or proposed date of commissioning for new RE for accreditation 

e) Copy of Off-take/Power Purchase Agreement or Undertaking 

f)  Confirmation of compliance of critical equipment with relevant applicable IEC or CEA Standards 

g) Undertaking for compliance with the usage of fossil fuel criteria as specified by MNRE 

h) Details of application processing fees/accreditation charges 

 The State Agency, after duly inspecting/verifying conditions elaborated above, shall grant ‘Certificate for  Accreditation’ to the concerned Applicant for the proposed RE Generation  project and assign a specific project code number to that effect which shall be used by the such Applicant (Eligible Entities) for all future correspondence with the State Agency. The process of accreditation shall normally be completed within 30 days from date of receipt of complete information by State Agency. 

After accreditation, registration with NLDC must be done. 

National Load Dispatch Centre (NLDC) is responsible for issuance of RECs.

Processing fees for accreditation approx Rs 45k
Processing fees for registration Rs 7k

Only Maharashtra, Orissa and Jammu and Kashmir have set the minimum size as 250kW. All other states do not specify a minimum size for REC projects.

The RECs must be sold within one year from the date of issuance, failing which
the RECs will lapse.




*What is the space / area / land required for the plant?

 Generally, it is assumed at 3.5 to 4acres for crystalline silicon (c-Si) 
technology and 6 to 7 acres per MW for thin film solar (a-Si or CdTe) technology. 
In reality, it depends on other parameters like cost of land, Ground Coverage
Ratio (GCR)(to avoid inter array shading, GCR can be 0.45 to 0.65 and 
generation will vary based on GCR) and choice of sun tracking 
systems (with sun trackers the land required will be about 6acres
per MW for crystalline solar modules).

 Which are the ideal states for setting up of solar power projects?

 Hot destinations are Rajasthan, Gujarat and MH, MP, Andhra, Karnataka,
Tamil Nadu as far as solar radiation is concerned. Presently, only 
Andhra, Rajasthan, Tamilnadu and Gujarat have a clear policy and guidelines on the procedures for 
setting up solar power projects. Other states may also initiate the policy 
and procedures soon now that Jawaharlal Nehru National Solar Mission has been 
launched by Government of India.

 Are Banks interested in financing solar power projects?

 The Debt Service Coverage Ratio (DSCR) works out to an average of 1.49
which is considered quite acceptable to commercial banks for sanction of loan. 
The maximum debt that is permitted as per CERC norms is 70% and most 
banks should find this acceptable based on the financial strength and 
net worth of the company / promoters. The present policy driven by the
National Solar Mission and PPA for 25 years with a central PSU like NTPC's 
subsidiary should provide adequate confidence to Banker to finance solar
power projects.





1. Ready to move & start facility for any solar power developer with clear title land.

2. Proper North-South oriented plots to be allotted so as to reduce land wastage, which are ideal for solar plant designing

3. Reduction in time to both start and execute the project.

4. No ROW (right of way) issue will be there for laying of transmission line, which will be done only once and common to all.

5. Ease of work execution and management will be there.

6. Relief from local issues which again will result into time and money saving in project execution.

7. Evacuation from individual project will be done right from the individual plot to the discom’s sub station at 132KV level.

8. Reduced transmission losses to the tune of 1/16th of the normal at 33KV.

9. Individual plant metering at pooling substation for ease of billing.

10. Security, preventive maintenance of approach roads & transmission line etc. will be done on periodic basis.

11. Grid down time is also minimum for 132 kV sub-station, which means higher revenue

12. Better financials than in your own lands.

13. Ideal for high net worth individuals

14. Ideal for NRIs


1. Your project is not in your state, benefitting your people

2. Your project is not in your lands. Absence of Prestige value in the neighbourhood.

3. You can’t to do the maintenance of the solar power plant directly and daily in your village

* Don’t have lands? See solar as a business opportunity. Go for Solar park.

* Want to invest in and  reap regular dividends with least hassles. Go for Solar park

  • Detailed design


As with any project, you need to know what you want to achieve. This basically involves detailing what you want from the captive PV installation, once installed. Do you want it to completely provide your day time electricity usage? Or do you want it to support a part of your usage? To start with, the scope of the project can be simple and later as we progress we can flesh it out to suit the requirements.

Defining the scope is in fact the most important step because once the basic scope is wrong, we might not be able to get the system do, what we exactly want it to do.


Solar insolation is the amount of electromagnetic energy (solar radiation) incident on the surface of the earth. Basically that means how much sunlight is shining down on the area under consideration.

The values are generally expressed in kWh/m2/day. This is the amount of solar energy that strikes a square metre of the earth's surface in a single day. Of course this value is averaged to account for differences in the days' length. There are several units that are used throughout the world.

By knowing the insolation levels of a particular region one can determine the number of PV modules that are required. An area with poor insolation levels will need a larger number of PV modules than an area with high insolation levels. Once the region’s insolation level is known, one can more accurately calculate collector size and energy output.

The typical thumbrule that is used for the amount of electricity that solar PV can produce is as follows: On average, 1 W of solar PV, at current crystalline silicon panel efficiencies, can produce about 4 Wh of electricity per day. This is however only an average estimate and based on the location, this could be a bit lower or higher than the average.


A site survey basically consists of a brief interview with the developer to get a feel for their electricity needs and a physical inspection of the proposed array site to see if it is suitable for solar. When a qualified photovoltaic design professional visits a potential solar site, he or she has many things to watch out for.

Primarily, they will be checking the roof's orientation (azimuth) and solar access. Orientation refers to the direction the roof faces - directly south is ideal, with some leeway to the Southwest or Southeast.

Solar access quantifies the percentage of time when the proposed array location will be receiving the full unshaded power of the sun during different days of the year. A shady roof might disqualify a site from receiving incentive money from the state, and is not a responsible choice for solar anyway. There are ways to get around shade issues - either by looking at alternate sites, trimming or removing trees, or by using micro-inverters in the system design rather than one large central inverter.


The next big task for any photovoltaic system designer is to determine the system load. This load estimate is one of the key factors in the design and cost of the stand-alone PV system.

A simple way to determine the approximate ceiling for the solar PV system capacity for all electricity needs is as follows:

1.  Find out your total monthly electricity consumption. Let’s say it is 100000 kWh

2.  Divide it by 30 to get an approximate daily consumption. In the example, it is about 3300 kWh.

3.  Using the thumb rule that 1 W of solar PV can approximately produce 4 Wh of electricity per day, you can determine the approximate maximum solar PV capacity you will require to power all your systems using solar PV. In this case, if the total daily consumption of electricity is 3300 kWh, you will require a maximum of 3300/4 = 825 kW.

 4.  It is however very unlikely that you would require such a high capacity for solar PV as you will need solar PV primarily as a backup power source, perhaps as a replacement for diesel based power generation.

 Ceiling for the solar PV required for complete diesel replacement

 In most cases, you will be using solar only as a backup power source to replace diesel based power production.

6.  One simple way to determine the amount of solar PV for this purpose is to determine the total amount of electricity you produce using diesel every month. In the example provided, out of the 100000 kWh of total electricity you consume every month, let’s say 10% or 10000 kWh is generated from diesel gensets. This provides you the ceiling for the solar PV system capacity for complete diesel replacement. In this case, it is 82.5 kW.

 7. As a thumb rule, one litre of diesel produces 4 kWh, so you can also compute the above with the data for the amount of diesel used every month.

 While estimating the load, the designer should consider energy conserving substitutes for items that are used often. Identifying large and/or variable loads and determining if they can be eliminated or changed to operate from another power source will save cost. 


 From the results obtained in step 2 and step 4, we can determine the size of the solar system that will be needed to power the site. The necessary systems involved in the setting up of captive power plants are:

 1)      Array(collection of solar PV modules)

 2)      Charge controllers

 3)      Batteries

 4)      Inverters

 5)      Mounting systems

 Note: The exact procedure for sizing of a solar system has to begin with calculating the amphere hour (Ah) of each load under consideration. Without knowing this it is impossible to size the PV system.

 PV array sizing – Array sizing is determined by taking into account the daily energy requirement (in Kilowatt hours) and average daily peak sunshine hours in the design month.

 No part of a PV array can be shaded. The shading of small portions of a PV module may greatly reduce output from the entire array. PV modules connected in series must carry the same current. If some of the PV cells are shaded, they cannot produce current and will become reverse biased. This means the shaded cells will dissipate power as heat, and over a period of time failure will occur.  However, since it is impossible to prevent occasional shading, the use of bypass diodes around series - connected modules is recommended

 Hybrid Indicator

 At this point, the basic PV system configuration and size have been determined. Before proceeding to specify components for the system, a simple test is recommended to see if the application might be a candidate for a hybrid system.

 Two main indicators work together to alert the designer to a possible hybrid application; the size of the load, and the seasonal insolation variability at the site.  The larger the load the more likely a hybrid PV-generator system will be a good economic choice. Likewise, in cloudy climates you need a larger system to meet the load demand; thus having a higher array/load ratio. Plotting the load versus the array/load ratio gives an indication of whether a hybrid system should be considered. There may be other reasons to consider a hybrid system: for example, systems with high availability requirements or applications where the load energy is being provided by an existing generator.  A word of caution--the controls required for a hybrid system are more complex because the interaction between engine generator, PV array, and battery must be regulated. Obtaining advice from an experienced designer is recommended if you decide to install a hybrid system. 

 Controllers - Charge controllers are included in most photovoltaic systems to protect the batteries from overcharge or excessive discharge. Overcharging can boil the electrolyte from the battery and cause failure. Allowing the battery to be discharged too much will cause premature battery failure and possible damage to the load. The controller is a critical component in your PV system. Thousands of rupees of damage may occur if it does not function properly. In addition, all controllers cause some losses (tare loss) in the system. One minus these losses, expressed as a percentage, is the controller efficiency.  The cost of the controller increases rapidly as the current requirement increases. Controllers for 12-volt and 24-volt systems with currents up to 30 amperes are available at a reasonable cost. Controllers with 30- 100 amperes are available but 2-5 times more expensive. Controllers that will switch currents over 100 amperes are usually custom designed for the application. One way to work with currents over 100 amperes is to connect controllers in parallel. It is often less expensive to use five 20- ampere rated controllers in parallel than one 100-ampere unit. 

 The controller must be installed in a weather resistant junction box and can be located with other components such as diodes, fuses, and switches. Excessive heat will shorten controller lifetime so the junction box should be installed in a shaded area and venting provided if possible. Controllers should not be mounted in the same enclosure with batteries. The batteries produce a corrosive environment that may cause failure of electronic components. 

 Battery sizing - To determine the size of the battery storage required for a stand-alone PV system, it is required to make a number of decisions. Before making these choices, one should study and understand battery parameters and the concept of system availability. First, you must choose the amount of back-up energy you want to store for your application. This is usually expressed as a number of no sun days, in other words, for how many cloudy days must your system operate using energy stored in batteries. There is no “right answer” to this question. It depends on the application, the type of battery, and the system availability desired.

 Inverters - Power conditioning units, commonly called inverters, are necessary in any stand-alone PV system with ac loads. The choice of inverter will be a key factor in setting the dc operating voltage of your system.

 When specifying an inverter, it is necessary to consider requirements of both the dc input and the ac output.   The choice of inverter will affect the performance, reliability, and cost of your PV system. Usually, it is the third most expensive component after the array and battery. 

 The selection of the inverter input voltage is an important decision because it often dictates the system dc voltage.

 An inverter should be installed in a controlled environment because high temperatures and excessive dust will reduce lifetime and may cause failure. The inverter should not be installed in the same enclosure with the batteries because the corrosive gassing of the batteries can damage the electronics and the switching in the inverter might cause an explosion. However, the inverter should be installed near the batteries to keep resistive losses in the wires to a minimum. 

 Mounting structures- Ground mounting of PV arrays is recommended for stand-alone systems. Regardless of whether you buy or build the mounting structure make sure it is anchored and the modules are restrained. Many module manufacturers and distributors sell mounting hardware specifically designed for their modules. This hardware is intended for multiple applications and different mounting techniques and considerations like wind loading have been included in the design. Using this mounting hardware is the simplest and often the most cost effective. Customized array mounting structures can be expensive.   

 Others- It is important to select wire, connectors, and protection components such as switches and fuses that will last for twenty years or more. To obtain this long life, they must be sized correctly, rated for the application, and installed carefully. Connections are particularly prone to failure unless they are made carefully and correctly. 


 Once the various components have been sized, the next important step is the selection and costing of the components.

 There are many players in the market vying to establish their products. At this juncture, the system developer has to select components by taking into account factors like technical specifications, reliability, and lifetime of the components in addition to the cost.

 Investment for the solar modules is for a period of 25 years, so selecting a high efficient solar panel is of prime importance. The manufactures of the batteries claim a lifetime of about 7 years, whereas inverters guarantee at most 2 years. As can be seen from these numbers, selection becomes a crucial part of the captive solar PV installation.


 Now that the major components have been sized and selected, it is time to consider how to interconnect everything as a working system.

 The detailed design is the more actionable form of the captive solar PV installation. The system developer accumulates all the data collected from the previous 6 steps and prepares a layout of the installation on paper. The developer removes obvious engineering fallacies and prepares a corrected version of the layout on paper.

 The confirmed design will have all the necessary data like the average consumption per day(kWh), the insolation levels at the area under consideration(in hours) , the optimal plant size, the area required for the same, the number of panels required to be installed in that area, the number of charge controllers, batteries, inverters required for the determined plant size, the cost of all the components and many more intricate details like the viability of installing tracking systems etc.

 Stand-alone PV systems will be reliable power producers for more than two decades if properly sized for the application, engineered well, and installed carefully. PV arrays for stand-alone systems are installed in many unique and innovative ways. However, there are common issues involved in any installation, whether the array is fixed or tracking, mounted at ground level, or on a pole or building. 

 Preventive Maintenance

 The integral part of any completed installation is the periodic checks that are recommended for any stand-alone PV system so that little problems can be found and corrected before they affect system operation. The system should be checked soon after installation when it is presumably operating well.











A stand-alone PV plant for AC and DC loads:

The broad steps involved in designing a roof-top stand-alone solar PV plant are:

  1. Estimation of total loads and energy
  2. Selection of an inverter
  3. Sizing of battery bank
  4. Sizing of PV array
  5. Selection of other components
  6. Installation and commissioning
  7. Testing and evaluation

Estimation of total loads and energy:

  1. Sum the total AC connected watts
  2. Sum the total DC connected watts
  3. Calculate the AC average daily energy requirement
  4. Divide this by the inverter efficiency to obtain the DC energy required to the AC load
  5. Calculate the total energy requirement due DC loads
  6. Add the DC energies obtained by step 4 and step 5
  7. This quantity is the total DC energy load on the battery bank


Selection of inverter:

  1. The capacity of the inverter must be more than that of the total daily average AC loads, including their surge requirement
  2. The nominal DC input voltage of the inverter will be the battery bank voltage and is decided by the design of the inverter
  3. The output will be single phase or three phase , 230/440V  & 50Hz, to be compatible to the AC loads requirement
  4. The conversion efficiency at minimum load (10%) should be 80%
  5. Total Harmonic Distortion (TDH) < 3%
  6. The wave shape, crest factor, power factor etc, to be as per the load requirements


Battery bank sizing:

  1. The total DC energy ÷ the nominal input voltage gives the daily Ampere Hour (AH) requirement from the battery bank
  2. The daily AH hours X autonomy ÷ discharge limit provides the battery bank Ampere hour capacity
  3. Battery bank AH capacity/Individual battery AH gives the number of batteries in parallel (generally it is 1)
  4. DC system voltage ÷ the battery voltage gives number of batteries in series



PV array sizing:

  1. Average daily AH requirement from the battery ÷ battery columbic efficiency gives the AH to be put in by the PV array in a day
  2. AH required from PV array ÷ average peak sun hours in a day of the site gives Amperes required from PV array
  3. Amperes from array peak ÷ panel (or module) peak ampere gives number of PV panel strings required in parallel
  4. Nominal system DC voltage ÷ nominal operating module voltage gives the number of SPV modules in one series string
  5. Number of modules in one series string X number of parallel strings gives the total number of SPV modules in the power plant
  6. Number of PV modules X PV module wattage is the total PV array wattage



Other components:

  1. Charge controller maximum current capacity should be one and half times that of total short circuit current of all parallel strings
  2. The total open circuit voltage of all the modules in series should give the maximum voltage of the charge controller
  3. The cables connecting the module to Junction boxes, to that of DC board and battery bank should be selected as per the standards
  4. Cut-outs, fuses and other control components should be as per the National standard of Electrical current ratings

Key words: Solar PV, photovoltaic system design, PV arrays, total AC and DC loads, selection of inverter for SPV, battery bank sizing, SPV array sizing, charge controller, SPV module, ampere hours (AH)


Domestic Rooftop GBI in Tamilnadu

All domestic consumers will be encouraged to put up roof-top solar installations.


You generate power and the Gov pays money for it !!


A generation based incentive (GBI) of Rs 2 per unit for first two years, Re 1 per unit foe next two years, and Re 0.5 per unit for subsequent 2 years will be provided for all solar or solar-wind hybrid rooftops being installed before 31 March, 2014.

A capacity addition of 50 MW is targeted under this scheme.

Implementation of this scheme can be tough.
The households will need a net meter approved by TEDA.
Will the incentive be deducted in the monthly electricity bill or will
one have to apply for it separately and wait is not known yet.

In the offgrid markets, like rural villages, the consumers will have 
to own a net meter to keep track of the electricity generated as proof
of solar electricity generated to claim the GBI from TEDA.

With the Solar Purchase Obligation (SPO) set to kick in from January 2013 for industrial and commercial consumers in Tamil Nadu, the details of its implementation need to be finalised for clarity, say industry representatives.


Industrial consumers with captive wind capacities are worried. To them, the SPO is an added expense even as they try to meet the 9 per cent Renewable Energy Purchase Obligation (RPO) in place under the prevailing laws . Those ‘obligated’ to meet the RPO are: distribution licensees, grid-connected captive power consumers and open access consumers.




The State Government, in its ‘Solar Energy Policy 2012’ set a minimum purchase obligation for these consumers; they would have to meet 3 per cent of their electricity needs from solar power from January 2013 and 6 per cent from 2014.


The Tamil Nadu Generation and Distribution Company estimates that over 1,000 MW of solar power generation will be needed by 2014 to meet the SPO. It plans to enter into long-term contracts with solar power producers and see adequate generation capacities in place by December 2013.


But consumers are left with limited options to meet the 3 per cent obligation from January 2013, when 500 MW of solar power will be needed. In Tamil Nadu, the installed solar capacity now is about 7 MW and about 1,000 MW across India, according to industry sources.


Under the policy, consumers can set up captive solar power generation, purchase Renewable Energy Certificates on the power exchanges or pay a ‘solar tariff’, equivalent to 3 per cent of their SPO, to the utility. But the solar tariff is yet to be fixed.


The rules and regulations need to be put in place before the system becomes operational in three weeks’ time, say industry representatives.


Pashupathy Gopalan, CEO, India, SunEdison, said details of the way the percentage obligation will be quantified, whether to be applied monthly or yearly, and percentage of electricity consumption or capacity need to be announced by the regulator, the Tamil Nadu Electricity Regulatory Commission. Consumers may need time to meet the obligation in 2013, he said.


The Tamil Nadu Spinning Mills Association, members of which own more than half the wind energy capacity of 7,000 MW in the State and meet RPO norms, are worried.


If the solar obligation is levied, it will be another load on them, according to the Association’s Chief Advisor, K. Venkatachalam.






On the REC front, Rajesh Vaidyula, Head, Business Development, RE Connect Energy Solutions, a consultant, says over 18 MW of solar photovoltaic RECs are registered on the power exchanges.


With Tamil Nadu alone set to generate a demand of about 500 MW of RECs from January 2013, the demand is bound to be steep. But enforcement and compliance are key to the SPO. In non-solar RECs, enforcement and compliance are low, he said.





 *  Posco and Tata Power to set up solar projects in Tamilnadu !?

Sungjin Geotech, an affiliate of the South Korean steel major Posco is keen on developing “200 MW and above” of solar power projects in Tamil Nadu. This was stated by Alex Kim, who represented Sungjin at a meeting that took place here of prospective solar power developers and that Tamil Nadu electricity utility, TANGEDCO.

Speaking to Business Line on the sidelines of the meeting, Kim said that Sungjin had been “looking for opportunities for solar projects in Tamil Nadu” for the last two-three years, but things were clear only now.

Asked if Sungjin would own all the 200 MW of solar power projects or would create a park in which other developers could put up their own projects, Kim said the company was open to all options.

Tata Power is another prospective solar investor in Tamil Nadu. Among those who participated in the investor-Tangedco meeting was Krishnan Rajagopalan, Manager (Strategy & Business Development). Krishnan later told Business Linethat Tata Power was examining the prospect of putting up a solar project in the State.

There were representatives at the meeting from Mytrah, GMR, Kiran Energy, SunEdison, Mahindra Cleantech and Enfinity.






 Solar power plants will not face power evacuation problem



The textile mills here have appealed to the State Government to remove the solar purchase obligation for High Tension consumers.

According to sources in textile mills, the Tamil Nadu Electricity Regulatory Commission has already fixed the solar renewable purchase obligation at 0.05 per cent and proposes to increase it to 0.1 per cent this year.

This petition is unlikely to succeed. Tamilnadu gov has a RPO, ie Renewable Purchase Obligation, year after year. 

They are only passing the obligation to other entitites who use the power the most in the form of Solar Power Obligation, spo.

Solar power developers have 90 days to achieve financial closure from the date of issue of the letter of intent

Solar power developers who are interested in putting up projects in Tamil Nadu are worried over the tight deadlines and power evacuation arrangements.

Developers who win rights to put up solar projects in the State in a competitive bidding process have 90 days to achieve financial closure from the date of issue of the letter of intent.

While even this is a very tough deadline to meet, a third of this time will be taken up by the State electricity utility, Tangedco, to do the ‘load flow study’ for the site and give its clearance. The load flow study is needed to ensure transmission stability, determine the suitability of the site and thus impact the very viability of the tariff offered. This is critical in today’s context in Tamil Nadu where wind power projects are often hampered by non-availability of the grid.

Many developers whom Business Line spoke to feel that doing the load flow study after the site is selected is putting the cart before the horse. Instead, Tangedco should do the study for a number of potential sites and make it public so that investors have the choice of putting up their projects there.

Since each sub-station has a limited capacity to take load, Tangedco should first announce how much more load each substation can take, says R.S. Ravi, Director, S.J. Renewables. The company works with a Belgian company called Enfinity, which wants to put up solar projects in the state.

Every single solar power developer that Business Line spoke to, without exception, said that the time given for financial closure was not reasonable.

The least Tangedco could do is to help developers by doing the technical studies for the projects ahead of the bidding process, they said.

In any case, the 90-days time given for tying up funding, according to developers, is infeasible. “It is not going to happen,” says Pasupathy Gopalan, Managing Director, SunEdison, an American company that has put up several projects in Gujarat and Rajasthan. He points out that the National Solar Mission gave six months after signing the power purchase agreement; yet a few developers could not achieve financial closure by the deadline.


New solar policy expected to generate 3000 MW






The Solar Power Obligation puts a huge financial burden on those who are already paying higher commercial power tariffs. However, it would be interesting to see if the obligation creates insurmountable financial pressure or acts as driver to be self-secure in power requirements. However, challenges are always associated with any new initiative but not insurmountable. Tamil Nadu’s Solar Policy will definitely play a significant role in powering state to meet energy requirements for realizing Vision 2023.

Written by Varun Mittal, Contributing Editor, India, Solar Novus Today

  Industrial and Commercial buildings connected to a high tension power load will have to use solar power to meet a portion of their power consumption ,  in TAMILNADu,  according to a solar energy policy announced by the Tamil Nadu Government on Saturday.

The policy offers incentives and mandates exploitation of solar energy in industrial, commercial and residential buildings. An official press release said, Chief Minister J. Jayalalithaa released the Tamil Nadu Solar Energy Policy 2012 on Saturday . The objectives of the policy are energy security, establishing 3,000 MW of solar power generation and encouraging production of solar energy equipment. The proposed addition to generation capacity will be over the next three years with 1,000 MW being added each year, the release said.

The State Government will mandate 6 per cent solar purchase obligation from January 2014.



The new policy was aimed at making Tamil Nadu a frontrunner in the solar power generation, it said. source


Auto majors looks at setting up captive solar power projects
The state would mandate six per cent Solar Purchase Obligation (SPO), starting with three per cent up to December, 2013,

  A 6 per cent ‘solar purchase obligation’ and a tapering generation-based incentive (GBI) are the cornerstones of Tamil Nadu government’s solar policy, unveiled today.

 In pushing investors towards the target of 3,000 MW in three years, the government makes it mandatory for large power consumers to buy six per cent of their consumption from solar energy producers or from the state generation and distribution utility at higher prices, or by buying solar renewable energy certificates.

 The Tamil Nadu Energy Development Agency will act as the single window clearance agency for solar power projects in the State. source

Solar parks with a capacity of 50MW each will be developed in 24 districts across the state.

The Tamil Nadu government on Saturday announced the Tamil Nadu Solar Energy Policy 2012, with an aim of generating 1,000 Mw of solar power every year from 2015, setting up of solar energy parks along with incentives for solar power producers and equipment manufacturers.

With the aim to generate 3000 Mw of solar power in the next three years, the government has also made rooftop solar panels mandatory for new buildings from the government and local bodies.



The aim is to make the southern state a front runner in the country with support of power produced from solar energy









Every household can generate the power it needs and also a little more, if only it were to install solar panels on the roof. “Our study reveals that a household will be able to not only meet its average requirement of 6,480 units but will also have a surplus of over 1,200 units,” says Ekanath Rangan, a Plus One student of Amrita Vidyalayam, Ettimadai.

He, along with classmates R.V. Manoj Kumar, Yadhu J. Kishan, S. Karthik Raj and E. Akhil, conducted a survey in Ettimadai to ascertain the power consumption of the households there. They then installed solar panel in the area to ascertain the power generated.

“We studied the power generation on three different days – a sunny day, a cloudy day and then a rainy day,” he says and adds that they did not average the power generated but tabulated the sunny day’s figure for 120 days, the cloudy day’s figure for 90 days and rainy day’s figure for 60 days.


The boys, as part of the survey, also found that each house in Ettimadai can hold 965 solar panels. This leaves each house with the capacity to generate 7,728 units a year, which is more than what it consumes.

If all the houses there install solar panels and also the Amrita institutions, the entire village panchayat will be energy self-sufficient. The panels at Amrita institutions will generate around 9,200 MW a year.

The entire generation there more or less equalled the power generated by burning 3,036 tonnes coal. And this reduces carbon foot print equalling 11,235 tonnes, Ekanath says.

Amrita Vishwa Vidyapeetham Vice-Chancellor P. Venkat Rangan says that the 9,200 MW a year generation target the boys have spoke about calls for establishment of 16 lakh solar panels across the Amrita institutions. And this is a realistic figure because the power generated is for a year.

The 3,000 MW or so the State Government has talked about in its Solar Energy Policy is the State’s generation capacity for an hour, he adds. This is true of almost every village panchayat in the State, he says and wants people to install solar panels.


*Interior Tamilnadu gears up for a dark Diwali

This year, it looks like the festival of lights will be celebrated in darkness. The entire western Tamil Nadu has been suffering power cuts that extend beyond 14 hours daily. On Wednesday, just four days ahead of Diwali, the region including Coimbatore, Tirupur, Erode and Salem, plunged into darkness at 9pm. The power returned early morning on Thursday, but just for an hour, affecting the festival shopping plans of many residents.

Electricity Board (EB) authorities attribute the grim situation to the almost negligent production of wind energy. Despite unexpected rains on Wednesday, a shortage of 4,000 mw of power has led to interrupted supply. As per the TNAU weather forecast, mild showers are expected in the next couple of days. The average rainfall this season will exceed 300mm, the forecast says.

TANGEDCO officials say that they are depending on the rains to bail them out of the power crisis. One of the five gas turbine power stations has been forced to shut down operations due to shortage of gas. This has worsened the power crisis, says a senior TANGEDCO official on conditions of anonymity.

The five gas turbine stations in the state include the one at Basin Bridge, two at Thirumakottai and one each at Valathur and Kuttalam which produce a total of 210mw of energy. "There is a sudden increase in the demand, which may be due to the lack of rain. The additional load is due to the increase in use of air conditioners and pumps by farmers," the official said. Due to lack of wind, HT consumers are using up their banked energy to run operations.

Meanwhile, residents continue to have sleepless nights. "It is impossible to get a good night's sleep without a working fan. Our only respite is an occasional cool breeze," said K Nazar, a resident of G M Nagar in Ukkadam. The situation became severe when many in his family fell sick due to lack of adequate sleep, he added.

"Children stand to suffer the most. Exams are just round the corner and with the long power cuts it will be very difficult for them to concentrate on their studies. Lack of sleep has affected the health of my children. I cannot afford to buy an UPS," said Rambabu Singh, another resident.




The state of Tamil Nadu has attracted an incremental investment of over Rs 1.74 lakh crore in the last 18 months. With these, the investments, which are in the pipeline in Tamil Nadu stand at around Rs 9.25 lakh crore in September 2012, as against Rs 7.50 lakh crore at the end of March 2011.

Speaking at the MoU signing ceremony with 12 companies, which would bring investment to the tune of around Rs 20,925 crore to the state, Tamil Nadu Chief Minister J Jayalalithaa said that investments in the pipeline in Tamil Nadu stand at Rs 9,25,285 crore in September 2012, as against Rs 7,50,579 crore at the end of March 2011.

This implies that Tamil Nadu has attracted an incremental investment of Rs 1,74,706 crore in the last 18 months.


“If we go by past trends, this marks a quantum jump in investment flows into Tamil Nadu. This includes a substantial amount of investments in Infrastructure projects such as power generation & distribution, road improvement, water supply augmentation, port development, health care, education, etc. All these will substantially improve the quality and reliability of our infrastructure and strengthen our competitive advantages in attracting investments into the Manufacturing Sector”.

The Chief Minister noted, the Department of Industrial Policy and Promotion, Ministry of Commerce and Industry, Government of India publication titled SIA Statistics published in June 2012, Tamil Nadu has attracted Rs 4,01,537 crore of investments in the Manufacturing Sector as against Rs 3,33,010 crore at the end of April 2011. The Incremental investment attracted by Tamil Nadu in the 14 months period from May 2011 to June 2012 is Rs 68,527 crore. 

“This is testimony to the fact that the investment environment in Tamil Nadu is very conducive to growth and expansion. Once again,Tamil Nadu is emerging as the destination of choice for making investments”.

“FDI is often a double-edged sword, and the Government needs to handle it, dexterously. FDI in some fields is purely based on private rationality with the underlying principle Private gain at social loss. The recent decision of the Government of India to open up our retail business to FDI is one such example, fraught with the danger of destroying our small business ventures that provide jobs to millions of our people,” said the Chief Minister, who objected the FDI in retail earlier.

She further said that Tamil Nadu Government is planning to introduce new policy reforms that include a New Industrial Policy, Automobile and Auto Parts Policy, Aerospace Industry Policy, Biotechnology Policy and much more. 

The Tamil Nadu Solar Energy Policy 2012 promoting solar and wind power projects has been unveiled on the October 20, 2012. The Automobile and Auto Parts Policy to be shortly released. “We are confident of attracting over Rs 1 lakh crore of new investments, in the Manufacturing Sector, surpassing all records and achievements made so far. I am confident of making Tamil Nadu the “numero uno” in all spheres of development.

*Tremendous Response to the adoption of solar energy in schools and colleges

From powering street lamps in colleges and water heating systems in hostels to lights and fans in classrooms, solar energy is the new kid on campus in Tamil Nadu. 

In its solar policy, the state government imposes a solar purchase obligation (SPO) on colleges, mandating them to meet 6% of their power usage from solar energy, and colleges are getting down to business. 

Going by the policy, commercial establishments, colleges, government buildings, residential schools, IT parks, industries, and buildings with a built-up area of 20,000sqm come under this obligation. They can meet this by generating their own power, purchasing solar power from the state electricity board, or purchasing power from private power producers.

Solar power generation in tamilnadu : the latest trends





Industrial consumers, frustrated by long hours of power outage, are now “taking solar very seriously,” says Pasupathy Gopalan, Managing Director of SunEdison, an American.

SunEdison is among the companies that are keen on developing solar projects in the State Most developers prefer to sell power directly to industrial consumers, who luckily for them are mandated to buy solar power under the State-imposed solar purchase obligations. Only NanoPV-Voltech, perhaps because the Indian partner already has business links with Tangedco.


Zynergy’s Managing Director & CEO Rohit Rabindernath finds tariff discovered through ‘reverse bidding’ un-remunerative. Selling to the utility at the ‘average pooled purchase cost’ (Rs 2.54 in Tamil Nadu) and getting tradable renewable energy certificates (RECs) is also not an option for him because no banker recognises REC income.

Further, selling power to Tangedco would call for some kind of payment security mechanism. Otherwise given the payment track record of the utility, no banker will lend on the basis of a PPA with Tangedco, developers say.


Selling power to paying consumers is more lucrative. Zynergy for one is confident of getting tariffs of Rs 9 and above — any income from RECs would be shared with the customer.

These project developers also have some common concerns. The first is about the enforcing solar purchase obligations, for, unless the obligations are fulfilled there would be no RECs.

The second concern is the cross-subsidy charges in Tamil Nadu (Rs 2.07 a unit for an industrial consumer and Rs 3.28 for a commercial establishment), which are levied when a generator sells power directly to a consumer.

Unless exempted from ‘cross-subsidy charges’, developers will have to get into the ‘group captive’ model to avoid the levy. This entails forming a separate company with power purchasers as shareholders. This model is messy and expensive because you need to incorporate separate companies for various projects and customers will have to invest in the equity.

However, many developers seem to be confident that the Tamil Nadu Government will exempt solar power from cross-subsidy levy.

Land availability seems not to be a big deal (unlike, say, in Rajasthan, where land ceiling law is a hurdle). In the last two decades, the wind industry has spawned a number of ‘infrastructure developers’ in the State who provide the service of buying land, organising grid connection and dealing with the local people and panchayats.

Finance, on the other hand, is seen as a challenge. Raising equity is no problem, but securing debt requires working on.

Solar developers believe that the State Government can do something here, perhaps have Tamil Nadu Industrial Investment Corporation provide easy loans.


This though is unlikely to happen. As was pointed out earlier, TN could have done two important things .1 Copied AP Policy in terms of Banking and wheeling charges, cross subsidy charges, vat charges etc and 2. worked at providing financial security



3000 MW solar power capacity in 3 years in Tamilnadu: News


Stung by criticism over the state government's passive support to the Kudankulam nuclear power project, the Jayalalithaa government in Tamil Nadu has announced a big boost to environment-friendly solar energy development programme in the state. The `Tamil Nadu Solar Energy Policy 2012,' announced by chief minister J Jayalalithaa in the secretariat today, envisages creation of 3000 MW of solar power generation capacity in the state over the next three years. The state government proposes addition of 1000 MW of solar power generation capacity each year for the next three years by creation of solar power generation facilities, the release said. The new policy banks on the falling prices of solar panels juxtaposed with the growing cost of grid power in India. The policy also involves large-scale power consumers into the initiative by mandating six per cent solar purchase obligation (SPO) on them. The SPO to be administered by the Tamilnadu Generation and Distribution Corporation Ltd (TANGEDCO) will be applicable to all high tension (HT) consumers, including SEZs and IT parks, but low tension (LT) consumers like domestic consumers, powerlooms, cottage and tiny industries, agricultural consumers will be exempted from the mandate, the policy said. Besides capacity creation, the policy aims at securing energy security and creating domestic production facilities for solar energy equipment. The policy attempts to leverage 300 days of clear sunny days available annually to tap clean, renewable energy source to contribute to energy security and development of the state.








*  Gov supplied power price to increase to Rs 13 to Rs 14 per unit 

a Bangalore-based solar firm with German technology has been invited to the southern districts to discuss technological and commercial viability. K.R. Thangaraj, president of Tamil Nadu Small and Tiny Industries Association (TANSTIA), told The Hindu on Tuesday that as per one of the proposals, the Bangalore firm would bear the initial expenditure for installing the solar equipment but subject to a minimum capacity of 250 KW. The firm would sell the power with a toll.


With policies on subsidies for diesel, coal and commercial gas changing, the tariffs of government supplied power would increase to Rs. 13 to Rs. 14 per unit in a few years. However, with China having entered the solar field in a big way, the cost of panels would come down soon.

Companies could adopt a cluster approach and go for solar power, which was both a constant and a clean source of power.

While 250 KW was the entry threshold, the industrial units could scale up based on the demand. Also, in the power sector, the country was constantly facing a significant gap in supply-demand.

Spanish engineering and renewables major Gestamp intends to put up a 100 MW solar photovoltaic project in Tamil Nadu, but in phases.

Southern Solar Pvt Ltd, a joint venture of Gestamp and Chennai-based Zynergy group, will put up the first 25 MW by March. Gestamp has 70 per cent stake in the joint venture. (Typically, a solar project calls for an investment of Rs 9 crore per MW.)

The joint venture has acquired 500 acres in Madurai and Ramnad districts, Rohit Rabindernath, Group MD and CEO, Zynergy, told Business Line on Thursday.

Rabindernath said that Southern Solar would prefer to sell the power it generates to industrial consumers directly.

It has signed MoUs with potential buyers for selling power from 10 MW of capacity and is in the process of negotiating the power purchase agreements with them. He said he is confident of being able to firm up PPAs for 25 MW soon, and hence the initial phase of the project would be for that capacity.

He said that evacuation of power would not be a problem because “luckily for us” there is no transmission constraints in the areas Southern Solar would put up its projects.

On the tariffs that the Southern Solar would sell electricity at, Rabindernath said that industrial consumers were fine with paying Rs 9 and above per unit. Anything less would not make economic sense for the project developers. Any benefits that Southern Solar would get from trading in the renewable energy certificates could be shared with the buyer of the electricity.

Southern Solar would not be interested in ‘reverse bidding’ projects, where the tariffs are determined in a bid process, and are often as low as around Rs 8.




Automobile manufacturers are slowly warming up to the Tamil Nadu government’s solar policy.

Truck maker Daimler India Commercial Vehicles is planning to set up a logistics warehouse with inbuilt solar panels at the company’s plant in Oragadam, Chennai. And Nissan is planning to power its offices in the country with solar energy.

“With Tamil Nadu being abundant in solar energy, we welcome the State Government’s move to make use of natural resources. Our other plants globally too make use of solar energy for sustainable business,” said Florian Laudan, Head, Corporate Communications, Daimler India.

The State Government’s recent solar energy policy makes it mandatory for industrial and commercial buildings connected to “a high tension power load” to use solar power to meet a part of their power needs. The government mandates 6 per cent solar purchase obligation from January 2014. Till December 2013, it will be 3 per cent. The policy also promises incentives and tax benefits for solar power production.

Speaking at a seminar on sustainability in the auto industry, Biju Balendran, Vice-President, Plant Engineering, Renault Nissan India, said solar water heaters have been installed at the kitchen inside its Oragadam plant. Nissan is now taking steps to power its offices in the country using solar energy. source






 Complete text of tamilnadu solar policy 2012 is here,

Full solar energy policy of tamilnadu 





This blog consists of three parts 

Part I deals with latest solar energy news from Tamilnadu


Part II deals mostly with the Government regulations and guidelines for solar energy in Gujarat.


Part III deals with solar energy business opportunities, solar energy business strategy, and solar energy investment required for different types of businesses all catering to the Private sector from large corporates to small medium ones. 


 One MW solar plant set up in coimbatore 

Industrial experts in Coimbatore, Tamil Nadu, have claimed that using solar energy is extremely beneficial in the wake of consistent and acute power shortages in the area.

According to media reports, nanotechnology has the potential to make solar energy affordable and cost-effective at the same time.

Coimbatore is well-known for windmills, but it has now made its foray in the realm of solar energy.

A one MW solar plant has been set up in Coimbatore and the energy generated is supplied to the grid.

Solar plants can be established anywhere in the state, especially on rooftops where solar panels are installed.

In the future, it is said that nano-materials may be used to transform heat generated from various equipment.

R. Challappan, solar energy producer and an industrial expert, on Monday, said that the alternative energy source was becoming increasingly popular to solve the problem of power cuts.

"We are getting a lot of enquiries, particularly from the manufacturing segment and hospitals and institutions. It looks like solar energy is the best option for establishing power continuity and improving productivity. So, with the help of the new policy, there is enormous hope and potential for the solar companies to contribute to society," he said.

Challapan said that Tamil Nadu was going through a dark phase, thus the need of the hour is to introduce energy sources that could increase productivity.

"We are going through series of power cuts all over, especially in the rural side of the country, but Tamil Nadu is really going through a dark phase, because of lack of generation and increasing demand. So, people have different mindsets and not relying on only source of electricity, they are looking at different alternatives," he said.

India, growing at around 5-6 percent per year, needs all the help it can get to ease the strain on its power sector, where supply already falls 11-12 percent short of demand during peak hours.

The world's fourth-largest crude importer also wants to cut dependency on costly oil and reduce the use of coal, where its huge reserves face production problems forcing it to supplement from outside. Solar can help cut use of diesel and kerosene-both heavily subsidised by the financially-strapped state.

India installed 300 MW of solar capacity in 2011, accounting for just 1 percent of the 29.5 gigawatts (GW) of new such plants in the period. Outside Europe, which accounts for 75 percent of the market, China installed the most last year with 2.2 GW.

India's USD 70 billion solar plans mirrors China's, with both aiming for solar capacity of 20 GW by 2020, although Beijing is expected to up that to 21 GW by 2015. (ANI)


*Voltech Group to set up solar park near Madurai


Attempting to expand its solar energy business, Voltech Group today started a new venture 'Solacon Energy Park Pvt Ltd' amalgamated with Arab Gulf Pearl Trading Co, UAE and NanoPV, USA.

Solacon would have a solar park established over 100 acres of land at Kadaladi near Madurai, M Umapathi, Chairman, Voltech Group, told reporters here. 

 "The operation and production of Solacon is intitially set up a 2 MW plant by end of March 2013 and gradually ramp to 10 MW. The plant will be using NanoPV technology," he said.


Anna Selvan John of NanoPV, USA said the company's technology was based on amorphous and nano-crystalline silicon and proprietary light-trapping and transparent conductive light-trapping oxide technologies.


"Based on this, compared with conventional solar cells, NanoPV's cell manufacturing involves one-thord the process and takes one-third he cost and 300 times less amount of material consumption," John added.


All the three companies - Adam Sheikh of Arab Gulf Pearl Trading Company, UAE and Dr Anna Selvan John of NonoPV, USA - also signed the corporation certificate, in the presence of the media.


City-headquartered Voltech is also involved in power, steel, oil-gas, infrastructure and cement sectors.


Madurai Kamaraj University to go solar due to severe power shortage

In the wake of severe power crisis, Madurai Kamaraj University is all set to join the solar bandwagon soon.

Having completed a comprehensive review of power requirements in its campus, the university is betting on solar power. A proposal has been prepared under the ‘green campus’ initiative and submitted to the appropriate authorities, including Finance Committee, for fund support. “The total consumption of power in the university was studied in detail and it was found that there is misuse of power to a great extent. While drastic steps are to be taken to tackle power crisis, a major plan is to tap solar energy,” Vice-Chancellor Kalyani Mathivanan told The Hindu on Saturday.

The university would switch over to solar power in a phased manner in view of the huge investment required. “I have asked the departments to have separate meters so that we will know consumption pattern and cost. Now that the energy audit is over, we will take it forward with the financial support of the State government and University Grants Commission,” she said.

The Vice-Chancellor said she had a meeting with officials in Chennai and New Delhi on the green campus proposal. A memorandum of understanding was signed with Auroville Foundation to use its expertise. S. Kannan, Chairperson in-charge, School of Energy, Environment and Natural Resources, said that the energy audit took into account the total number of lights and fans in all departments, streetlights on the campus, hostels and public places, besides the power consumption of laboratories. “Since uninterrupted power supply is needed, it has become imperative to explore for alternative sources. As a first step, solar panels will be put up for the main block and distance education wing.” Already, one solar power plant was inaugurated in the university in April and it is meeting the electricity needs of one building. The green campus committee headed by the Vice-Chancellor has been meeting periodically to finalise the proposals and discuss the funding sources available.

Dr. Kannan said that the university had organised Dr. C. E. Sooriyamurthy Endowment Lecture on Monday. Vice-Chancellor of Kalasalingam University P. Kanniappan, who delivered the lecture, had suggested the formation of South Indian Energy Network to propagate the use of alternative sources of energy.


*DRDA calls for uniform procedure for setting up solar power plants

The District Rural Development Agency should evolve and implement a uniform procedure for setting up solar power units, with a view to achieving the State government’s objective of supplementing the growing demand for energy, said a cross section of councillors at the District Panchayat Council meeting held here on Friday. They wanted a coordinated effort to be taken by the district-level officials and block-level rural development officers.

Initiating a discussion, Rajkumar (AIADMK) said Chief Minister Jayalalithaa has been taking serious efforts to tide over the crisis due to shortfall in production. Setting up of solar energy-based installations has been one of the important initiatives in this regard.

He alleged lack of proper guidance on the part of rural development officials in achieving the goals. “Although I have been seeking the procedure for setting up the solar installation in villages in and around Manapparai, the block-level officials failed to coordinate,” he said.

Thangavel, another councillor, intervened to say that the procedure should be codified properly so that panchayat councillors could motivate villagers to set up solar installations.

T. Rajathi, District Panchayat Chairperson, who presided over the meeting, also joined the issue, blaming the officials for their poor coordination in this regard. The procedures stipulated by the block officials were inconsistent with the ones suggested by district level officials.

An official from the District Rural Development Agency assured the councillors that he would advise block development officials to adopt a uniform and hassle-free procedure.

K.P.T. Alagarsamy, a councillor representing Marungapuri ward, pleaded with Forest Department officials to allot a piece of land measuring 100 metres near Oonaiyur for laying a road linking A.Pudhupatti. In the absence of the road, villagers had to circumvent about three km. He also complained about massive damage to crops by wild animals.

V. Ilango, Forest Ranger, Manapparai, said the councillor could submit a proposal to the forest department for transfer of land to Marungapurai panchayat union for providing the road facility. As for checking the animal menace, he suggested setting up of solar fences with approval by the Forest Department.

When a discussion on delay in executing the road over bridge at Manapparai, Oyyamari, Lalgudi and Crawford was taken up, an official from the Highways Department said the general election and by-election last year delayed the process of land acquisition particularly in Manapparai. Steps were now being taken to expedite the work. The bridge at Oyyamari, located on the banks of the Cauvery, involved shifting of water pipelines and electric poles. In fact, the work on construction of the road over bridge at Tiruvanaikovil (which served as a diversion route for vehicles via Oyyamari) would be taken up only after the completion of the work at Oyyamari.



The Tamil Nadu Government has commenced the implementation of its ambitious programme to provide solar-powered lights to 300,000 homes in the State.

Work on this has been going on in the last couple of weeks in the Tiruchi district and 60,000 homes would be lighted in the current financial year, Sudeep Jain, Chairman and Managing Director, Tamilnadu Energy Development Agency (TEDA), said today.

Speaking at a conference on the ‘Dependability of REC mechanism, RPO and power trading in solar industry,’ organised here by the Energy and Fuel Users’ Association (ENFUSE), Jain said that the Tamil Nadu government was also implementing another programme to energise 100,000 street lights with solar power, at a cost of Rs 200 crore. ENFUSE is an organisation which is supported by the major oil companies such as ONGC, IOC and CPCL and the conference was sponsored by CPCL.

Both the home light and street light programme are grid-backed, “the first of their kind in the country,” Jain said.

The Voltech group of Chennai and the US-based NanoPV have joined hands to put up a 100 MW solar module manufacturing plant near Chennai and a solar park near Tuticorin.

Voltech is a medium-sized group that is into the manufacture of transformers.

Setting up a cell and module manufacturing plant may appear foolhardy at a time when global majors are being toppled by the Chinese companies’ onslaught and the slowdown in the European economy. But NanoPV’s President and CTO, Dr Anna Selvan John, says that the company has unique and patented technology that enables it to be competitive even in this market.

“NanoPV has unique technology based on amorphous and nano-crystalline silicon and proprietary light-trapping and ‘transparent conductive light-trapping oxide’ technologies,” says the company’s Web site. Because of this, compared with conventional solar cells, NanoPV’s cell manufacturing involves one-third the process and takes one-third the cost, and “300 times less amount of material consumption.”

Voltech’s Managing Director, M. Umapathi, said that the group has near Chennai a factory building where it once produced textiles. NanoPV intends to bring in plant and machinery from the US and set up a production line here.

The initial capacity would be 10 MW and would gradually be ramped up. Umapathi estimates the cost of the project to be Rs 100 crore.

Solar farm near Tuticorin

Another joint venture of Voltech and NanoPV is putting up a 100 MW solar farm near Tuticorin. The project will be implemented in phases, and work has begun on the first 10 MW.

In this venture, a UAE-based company called Arab Gulf Pearl Trading is also participating. It has taken 50 per cent of the equity. This project too would cost Rs 100 crore.

Work has commenced on the first 2 MW, which will be completed by March 2013. The other 8 MW will be ready to produce power by the end of 2013, Umapathi said.

NanoPV says that its modules can generate 1.8 million units of electricity per MW each year.

The joint venture intends to enter into power purchase agreements with industrial consumers in the state, forming a ‘group-captive’ structure.



Solar energy fever catching up

Go solar is now the catchword among many. The long hours of power cut has prompted several households to go in for the system.

R.R. Balasundaram, who runs an industry In Coimbatore, has installed a 1.2 kilo watt (KW) solar photovoltaic system at his house seven months ago. Later, he augmented it with another 0.4 KW.

The 12 solar panels on the rooftop of his house and six batteries had cost him Rs. 2.5 lakh. He had connected lights, fans, television, computer, mixer-grinder and washing machine to the system. Besides, there was a separate solar water heater. Only an air-conditioner and a refrigerator were not covered.

“The bi-monthly consumption of electricity has gone down to about 300 units from 700 units. I am paying at least 50 per cent less than what I was paying earlier,” he says.

“When there is no power supply during the evening or night, I still watch the television. The power comes from the batteries that store the solar energy. The batteries carry a guarantee for five years. We need to clean the panels once a week or if it rains, just once a month,” he adds.

Some months ago, K.V. Kuppusamy, chairman of RVS educational institutions here, installed the system at his house. Satisfied with it, he was planning to have 600 KW of solar system in the premises of his six educational institutions. “Though the capital cost is high, subsidies are available and you are assured of 24 hour power supply,” he says.

Non-availability of dedicated feeders discourages private colleges from opting to wind power as they do not get much relief during load shedding. But, solar panels provide instant relief, says Mr. Kuppusamy. Yet, there are persons such as M. Kandasamy, an industrialist, having reservations over the utility of solar power. “I spoke to some suppliers and they say solar is not that attractive for houses. I have to study the installed systems before taking a decision,” he says.


solar panels, solar power, solar inverters, Tamil Nadu power crisis



Net metering

Jain said that the Government of Tamil Nadu was also very keen on net-metering. (Net metering enables the rooftop solar plant can put in surplus energy into the grid because it spins the other direction when power is being put into the grid, thereby giving credit to the generator.)

He noted that two pilot net metering projects were on—one in TEDA’s own office building and another at Auroville, Puducherry. He said that when net metering became a reality, rooftop solar plants could do away with the costly and energy-inefficient battery-based storage.

Jain also hoped that just as the prices of solar panels have fallen drastically (from $2.5 a watt in 2009 to around $0.65 a watt now), the prices of inverters would also fall.

He said that the cost of putting up a 1 kW rooftop solar plant had come down from Rs 2.5 lakh a couple of years back to Rs 1.5 lakh and said that if the cost of inverters came down, the overall cost would come down to less than Rs 1 lakh per kW. The rooftop solar movement would take-off then, he said.


*Tamilnadu Green Power Policy is in its final stages. 

 Rain water harvesting was made mandatory by CM Jayalalitha earlier, she needs to take a similar stand on the use of renewable energy.

The Tamil Nadu Energy Developers Association has recommended that the setting up of solar power plants in commercial and large residential buildings be made mandatory. This concept has been successfully implemented in Europe.

T. Vijayakumar, GM, special projects, of wind power technology major, Gamesa, said, “Other States like Karnataka, Maharashtra and Gujarat have given a big push to renewable sources of energy. In Mumbai, common areas in large apartment complexes are lit by hybrid power plants. This is because solar power prices are on par with those supplied through the grid. In Tamil Nadu, if you compare prices, solar power is higher by Rs. 2 to Rs.3.





Solar Parks of Tamilnadu will employ 25000 people

The proposed solar park projects are to be implemented by Tamil Nadu Industrial Development Corporation, the nodal agency for industrial development in the state, according to the announcement made by the state industry minister P Thangamani in the assembly.

The solar park project will be established in several districts gradually through public and private investments. However, more details about the projects are anticipated in the coming days as the state is expected to announce a separate clean energy policy to boost investments into the state.

Tamil Nadu has launched its mega solar rooftop programme for providing solar powered green Houses (3 lakh houses by 2015-16).

About 60,000 green houses will be provided with solar lights during 2012-13 at a cost of Rs 180 crore. It has also launched solar powered street light scheme and is proposing to energise 20,000 streetlights through solar power this year and has set a target to energise 100,000 streetlights by solar power by 2015-16.






Tamilnadu will get 5000 MW  solar power in the next 11 years

The Tamil Nadu Industrial Development Corporation Limited (TIDCO) will establish Solar Power Parks in the State to generate 1,000 MW of power in the next five years. These projects would be implemented in a phased manner across the State both through government and private firms.

Initially Rs thousand crore will be invested in southern parts of the state over 500 acres to produce 100 mw, Industries minister P Thangamani told the state assembly.


Solar Power to the rescue

At a time when the whole state of Tamilnadu is reeling under power cut this article is relevant.

when the power supply was suspended abruptly in Theni, residents were resigned to their fate to beat the sweltering heat, while office rooms came to a standstill.

But one building that continued with its business as usual was the office of the Planters Energy Network (PEN), an NGO that offers electricity solutions to the plantation industry. But for the air-conditioner, the entire electricity needs of the office are met with solar power.

Here's hoping more offices turn to solar energy which is free and available in plenty.






Shortage of power in Tamil Nadu,  around 3,000 MW, will halve in  3 months !

Speaking at a conference on energy, organised here by the Federation of Indian Chambers of Commerce and Industry (FICCI), Mr Viswanathan said that as much as 416 MW of additional capacity would become available to the State by January 10. These would come from projects in Tuticorin and Neyveli.

*  TNEB's alarming financial position is due to non-revision of power tariffs 

Debt incurred by the TNEB is nothing but public debt, and we citizens will eventually be the ones called upon to pay for it. Ultimately, there is no escape from a future reality of significantly higher tariffs for the power we so desperately crave and consume. And the sooner we accept this fact and get ready to pay appropriate charges for power, the better it will be for us — and the TNEB.

A very interesting article well written by 

Mr R. Poornalingam Business line

The Board recently filed a proposal for tariff revision before the Tamil Nadu Electricity Regulatory Commission (TNERC). Hopefully this tariff revision will help the TNEB back to solid financial ground. But consumers should be prepared for a steep hike in rates, given the Board's huge losses and the accumulated debt burden.

Augmenting capacity is essential to meet the rising demand of industry, and the soaring aspirations of citizens. But to make this happen, a healthy balance sheet for the TNEB becomes mandatory. Only this will infuse confidence among private investors. Equally important is the creation of additional capacities by the TNEB itself.

* Tenders for 50 MW solar coming up soon in TN !

The Tamil Nadu Government will soon come out with tenders calling for bids for solar power projects for a total capacity of 50 MW, Mr Sudeep Jain, Chairman and Managing Director, Tamil Nadu Energy Development Agency, said today.

 We want to promote both technologies, Mr Jain told journalists later, on the sidelines of the event. He said that the details of the tender were being worked out. source

* 1000 colleges in TN to implement rooftop solar 

The authority is also planning to conduct a campaign from December 15 in around 1,000 colleges in 10 cities to implement roof top solar power generation. It would also float tenders for construction of 60,000 solar-powered green houses.

Of the total power generation capacity of around 10,000 Mw in Tamil Nadu, almost 6,547 Mw —which accounts for around 60 per cent of the total capacity — is from wind power, said Kabilan, chairman, Tamil Nadu Electricity Regulatory Commission.

However, the state still has to rely on conventional methods. With the price and import cost of coal going up, a tariff rate hike is inevitable to meet the expenses of coal-based power generation at least in the long-term, if not short-term. source

‘Surplus power in Tamil Nadu by 2015’
Inaugurating a seminar organised by the Federation of Indian Chambers of Commerce and Industry here, he said the additional one hour power cut being imposed in the state barring Chennai would be lifted by January next. He said the state presently faced a power deficit of 3,000 MW. By commissioning new projects, the State would add up 1,600 MW by May 2012 and 1,400 MW by the end of the year. By 2015, the state would be power surplus and a model for other states in the country in power generation. source

Tamil Nadu would be a power surplus state by 2015 by optimising production and speeding up new projects, Electricity Minister Natham R Viswanathan said . source

*  Jayalalithaa to make a policy statement on  Solar energy, renewable energy  soon !

Against the installed capacity of 11,500 MW, the production was 8,500 MW. With the anticipated addition of 4,500 MW during 2012, Tamil Nadu was poised to become a power surplus State, as was the case in the earlier AIADMK regime, the Minister said, addressing the valedictory function organised to honour winners of State-level inter-school competitions conducted since October by the Tamil Nadu Energy Development Agency (TEDA) in association with Rotary International. The ‘Green Energy Virumbuvom' campaign carried out through 300 Rotary clubs reached about five lakh students and 3.5 lakh students from over 750 schools across Tamil Nadu took part in the competitions.

The Chief Minister's policy statement, he said, would reflect a long-term vision to promote renewable energy: wind, solar, and biogas, factoring in the rate of depletion of coal reserves for running pollution-causing thermal power stations.

The era of rationalisation has arrived. Diesel, Petrol, Cooking gas are all getting rationalised. The prices are tied up with international rates of crude.

Thank God ! Electricity rates cant have the same rule. Atleast it is not going to be the same as in California. Which is supposed to be near 25 cents per unit. ( pl Chk).

But rates are going to go up for all of us. Rates for commercial usage is going to go up. In residences it will go up for those who use more .

Grid Connected Solar System

The quantum of grid connected solar system in Tamil Nadu is at present only 0.165 MW and that of India is 47 MW. As per the preliminary potential assessment study by World Institute of Sustainable Energy (WISE), the estimated gross potential for land-based grid connected Solar PV in the State is in the range of 4,000 MW to 21,700 MW. 

The government is keen on tapping solar power and has almost finalised its policy on roof top solar power generation systems. Those who generate with roof top systems can consume the power so generated and also feed the surplus to the grid.

The state Principal Secretary (Energy) P.W.C. Davidar said they were waiting for some clarifications like the price at which this power could be fed to the grid before finalising the policy.

The government is planning to install meters at distribution transformers and feeders and use of information technology (IT) for meter reading and billing.


Solar Steam Cooking systems

The Government of India (MNRE) subsidy is available upto 30% of the cost. The State Government also sanctioned an amount of Rs.2.40 lakhs for providing 40 Nos. Solar Dish Cookers at full cost to Noon Meal Centre / Hostels during the year in 2006-07. The same was allotted to the Most Backward Class and Denotified Communities Welfare Department Student Hostels.

Solar steam cooking system are also available which can be installed where boilers are used for steam generation and the food cooked for thousands of persons. Such a system installed in Tirupathy temple is working well.

Status of Rooftop Power

Under the Rooftop Power and Stand alone Small Grid-connected Power scheme, seven SPV projects, of each 1 MW capacity have been sanctioned for the State.

TN Tariff for solar Power

The State has announced the highest tariff of Rs.18.45 against Rs.17.91 per unit fixed by Central Electricity Regulatory Authority (CERC) for solar power under rooftop PV and small solar generation programmes of Jawaharlal Nehru Solar Mission.

The Tamil Nadu government plans to come out with an action plan on climate change on the lines of the National Action Plan for Climate Change (NAPCC) to promote renewable energy in the state. Besides, Tamil Nadu Electricity Regulatory Commission (TNERC) has set up a renewable energy purchase obligation (RPO) at 14 percent for 2010-2011.

The Tamil Nadu government plans to come out with an action plan on climate change on the lines of the National Action Plan for Climate Change (NAPCC) to promote renewable energy in the state. Besides, Tamil Nadu Electricity Regulatory Commission (TNERC) has set up a renewable energy purchase obligation (RPO) at 14 percent for 2010-2011.

In line with NAPCC, the Tamil Nadu government is also in the process of formulating an Action Plan on Climate Change. Solar energy will get due significance in this plan.

Under the scheme, seven solar photo voltaic projects of 1 MW capacity each have been sanctioned for the State.

Solar Roadmap of Tamilnadu by CII

To explore the potential of solar energy sector in Tamil Nadu the taskforce on solar power of the CII Tamil Nadu State Council has embarked on an initiative, and drawn the report on "Solar Road Map in Tamil Nadu: Opportunities and the Role of Government and Industries”

The National Action Plan on Climate Change (NAPCC), which incorporates India’s vision of sustainable development, has recommended minimum share of renewable energy in the national grid to be 5% in 2009-2010, increasing 1% every year during the next 10 years to reach 15% by 2020.

The Jawaharlal Nehru National Solar Mission aims to create an enabling policy framework for the deployment of 20,000 MW of grid-connected solar power by 2022.

The CII Road Map says that to meet this long term national target, two renewable energy technologies: wind and solar have to play an important role considering their distinct advantages in terms of resource availability, short gestation period and current stage of technology development.

“Beyond the NAPCC target, it is in the interest of State Governments to invest in renewable energy to mitigate the current power crisis, without waiting for long gestation conventional projects to materialise,” it adds.  

The report points out that the total installed power capacity of Tamil Nadu is about 14, 770 MW, comprising generation from thermal, hydro, and renewable sources of energy. 

Tamil Nadu is the only State in India which gets 35% of its installed capacity coming from renewable source of energy. However, the major contribution is from thermal sources - about 48% - and hydro and nuclear by 14% and 3% respectively. 

To meet the ever growing needs of energy, the State Government has to tap the solar energy, which is the single biggest source of renewable energy and offers unlimited potential.

Solar water heating systems in tamilnadu incentives and subsidies 

In view of its inherent advantages, the State Government had made the use of Solar Water heating system mandatory in certain types of new buildings in the State in the year 2002, by amending the building bylaws.

The Government of India (MNRE) is providing soft loan @ 2% to domestic users, 3% to institutional users not availing accelerated depreciation and 5% to industrial / commercial users availing depreciation through IREDA and Public / Private sector banks etc. Capital subsidy equivalent to upfront interest subsidy @ RS.1100/- per sq.m of Collector area will be available to registered institutions and Rs.825/- per sq.m. of Collector area to registered Commercial establishments that do not avail soft loans.

The State Government had also earlier provided subsidy to domestic and institutional users for installing the Solar Water heating systems. But now, it has been restricted to providing 100% cost for installation in Government institutions. Every year, a few Government Hostels / Hospitals have been provided with these systems.

Solar business opportunities: Tamil nadu

The Solar business opportunities mentioned below are not specific to Tamilnadu. They are industry specific opportunities. However in the whole of India, Tamilnadu has a very high incidence of irradiation and has a pretty good  potential for solar energy. 



 Opportunities in solar energy in Tamilnadu:


1. Solar powered desalination, plans, projects and opportunities

Tamilnadu  has the third longest coastline in India at  900 km. 

The opportunity is to build Solar desalination plants.

Tamilnadu is power starved and it  has plans for this. Very soon, the coastal belt is going to be economically strong because of availability of solar energy derived  good water and additional power.Making potable water and selling them inland is a business opportunity coming out of solar energy, all along the coast.

Cost of land all along the coast is likely to go up. Economy of the coastal villages will be bumped up. Fishermen will be able to store their catch in nearby freezers.  For more about the opportunites in solar desalination in tamilnadu click here


 2. Floating solar plants.

India has 30000 sq km of captured water bodies. If even 1 % of that area is utlised - it will equal 1500 large coal plants. Tata's have a tie up with an Australian company called Sunengy. There is a French company by name Solarsis synergy which is into having Floating solar plants. The technology is different.And there is another company called sgpsolar. It is based in California in usa. It is a good opportunity for Indian companies to look at this opportunity where Tata's have moved in fast. There are also some startups in this field and it may be worthwhile to start doing some research in this field in India itself.

3. A low cost solar energy solution for the indian industries 

Solar Heat for Industrial Purposes, the Market in India, the Business, the Opportunity, Cost Advantage of Solar Process Heat SHIP Solar Heat for Industrial Purposes The market for industrial heat in boilers is estimated to be 26 billion dollars per annum in usa alone. Solar steam produced is estimate to costs $ 4.60 per MBTU compared to average cost of natural gas powered steam of about $ 6 to $ 10 per MBTU.

This estimate is as per one the companies in Solar Heat for Industrial processes (SHIP). Indian entrepreneurs should take up such projects that cut down co2 emission and is less expensive. There are several companies that are into SHIP in USA. One of the claims that their process is CO2 emission free. Obviously because they use solar energy. The company also claims a reduction in the cost by as much as 50 %.

4. Captive power plants .

Many factories, companies, office complexes, textile factories, cement factories, sugar mills and many other small and medium industries need back up power. What is being talked about as an opportunity is this back up power. Actually already many companies in India already have captive power generation. But there a lot more number of companies in India which can benefit from this captive power plant from solar energy. There are some financial benefits and also the benefits of RECs otherwise known as Renewable Energy Certificates which are tradeable. There is good report on this at

Reading up the report will open up the opportunity for the above mentioned factories for their own back up power ie captive power. Those who are marketing minded and those who are solar energy consultants or renewable energy consultants, this is a very good business opportunity in India.

Interested in setting up a solar power plant for your factory!              


5. Education and training


MNRE expects that there is going to be a need for 100,000 trained professionals in the next 8 years.

I think that is a gross underestimate.

This opportunity is not just for individuals who want to learn and get jobs. Or learn and start a business or set up a training center as a businessman. OR u can even set up an online course for the whole world. The limitations are your imagination.

I foresee many training centers both for unskilled and for postgraduation education courses happening soon. The course contents given in the sample solar eduction centers, will be Indianised by the shrewed Indian businessmen.

Some of them may go for tie up with universities abroad.


For example they may have a tie up with a US university in Pune or a tie up with an European university in Jalgaon.

This is the largest collection of educational institutions and training on solar energy in India.

The above blog has a list of international institutions.


6. Solar inverters:

In a Global Clean Technology Conference on February 23-24 in New York, with more than 100 public and private companies and 700 attendees, including strategic and financial investors, high-level policymakers and industry thought-leaders in attendance the following question was asked as a part of a Survey.

Question: Within solar, which sectors of the supply chain are the most attractive investment themes?

(Please rank with #1 being the strongest):

Inverters 1

Cells/Modules 2

Projects/Installation 3

Polysilicon 4

Manufacturing Equipment 5

Wafers 6

The results of the survey are given in green color.


That is why I am calling it a great solar business in the Indian market too.

700/800 of the world’s leading practioners have identified Inverters as the most attractive investment theme.

It is a good business opportunity.

Solar inverters in India, manufacturers, cost and business opportunities




7. Micro grid :

The electrical needs of rural households are relatively small (0.5-2.5 kWhr per day) and a micro-grid system of 20-35 kW would suffice a small village. This may not be a 100 % solar solution. 

Lot of research is going on in this.

It is a good business opportunity.

Will research and write more about this opportunity soon.



8.Solar Irrigation Pumps :

This is a big opportunity area. Already being catered to in many villages.

Solar powered irrigation is an urgent need.

Read more about it in solar water pump blogs in


Interested in setting up a solar power for solar pumps !!            


9. Solar thermal 

India on an average has 300 clear days of sun and the radiation in most parts is 4.5 to 6 kWh/m2/day, which is pretty high. 

Solar thermal projects  concentrate sunlight on a fixed point and uses a medium to move the stored heat energy to a place where it can be converted into electricity by superheating water into steam and using the steam to turn a turbine that generates electricity—ultimately the same process that natural gas and coal-fired power plants use to generate electricity.
Solar dryers can be used in agriculture.

At present the waste is just exposed to the sun and dried. Solar water heating. It is being made mandatory in many states to heat water for bathing purposes with solar water heater in all new buildings. Solar thermal can be used for cooking, community cooking in hotels, villages, schools in villages, etc
Several industries that need low to medium heat can use solar thermal technology to reduce air pollution and carbon foot print.

Can someother reader in our club create a page for solar thermal energy in india, laws statewise, uses, companies doing it, states that can benefit from solar water heater and other solar thermal usage, market estimates, opportunities for the business minded, etc 

Thanks in advance



10. Distribution of solar products : There are many large companies manufacturing offgrid and grid connected products using solar energy, You can become a franchisee for them in your area.

This is good opportunity, Search for solar companies in eai club and apply to them.


11. Maintenance of Solar power generation plants and solar farms: 


Stay tuned for more. Not many large projects are coming up as of now as the solar energy policy of tamilnadu has not yet been finalised.


12. Opportunities in Solar cities: There are going to be about 60 solar cities coming up in India. What business opportunity exists in these solar city concept of mnre is a question in the young minds of indians. Will try and answer them in the coming weeks. Stay tuned.

Overall, my intention is that many Indians are bent on contributing to the society by getting into renewable energy business in india. The question in their minds is How can i get into solar business. or what business in solar in india. or what business can I do in solar energy in india. etc.,

Besides suggesting business opportunities in solar energy in India for large and medium companies, I thought it will be useful for small and individual players, if I can explain as to how they can get into solar business in India.

Tamilnadu solar policy. The new one is expected from the new governmnet anytime soon.

Solar Power Projects in Tamilnadu


Located in the hinterland is a project that proved to be a trump card for those advocating solar power as a solution to the power crisis in the State.

Spread across 65 acres in Rettai Pillai Ayyanarkoil, a tiny hamlet near Muthupatti in Sivaganga district, the 5-MW solar grid interactive photovoltaic (SPV) plant has exceeded the targets set in the planning stages, according to government and company officials.


Constructed at a cost of Rs. 100 crore, the plant has come up with funding from IDBI and the International Finance Corporation, a part of the Washington-based World Bank Group.

The Sivaganga project, identified by the Tamil Nadu Energy Development Agency (TEDA) and implemented under the Generation Based Incentive (GBI) scheme of the Union Ministry of New and Renewable Energy, was commissioned on December 20, 2010. A power purchase agreement was signed with the erstwhile Tamil Nadu Electricity Board (TNEB) for Rs.4.50 per unit. A GBI pact was concluded with Indian Renewable Energy Development Agency (IREDA) for Rs. 10.50. Totally, the plant yields Rs.15 per unit.

Being operated by Moser Baer Clean Energy, the project has a plant load factor of above 20 per cent against the Central Electricity Regulatory Commission’s stipulation of 19 per cent, according to its senior manager Kanagaraj Ramachandran.

The average daily production of the plant has been around 24,500 units. Excluding four per cent of the production for internal consumption and loss, the remainder is fed into the grid. In March 2011, the highest monthly generation was achieved with 31,500 units. This month, it was so far 31,200 units. Even in recent days of heavy rains, the plant has generated around 15,000 units, he says

Tamil Nadu has a major advantage over Rajasthan and Gujarat, leaders in the field, as the State does not have sand storms which damage solar panels and reduce their efficacy.

Further, he says, the Sivaganga solar farm uses amorphous silicon thin film technology, considered better for Indian climatic conditions. Even though crystalline film technology occupies 90 per cent of the solar photovoltaic market, it is more suited for European conditions. Thin film technology requires double the quantum of land compared to the crystalline film method, Mr. Ramachandran says. However, the land is not a problem in the Sivaganga region where most of the area is dry and arid.

Welcoming the Solar Purchase Obligation mooted recently by the State government, he says it will greatly attract investors to this technology as they would have assured returns.

In the Solar Energy Policy 2012 which targets 3,000 MW through solar power by 2017, it has been made mandatory for large power consumers to buy six per cent of their consumption from solar energy producers or from the State generation and distribution utility at higher prices or by buying solar renewable energy certificates.


Government officials say the Sivaganga project can serve as a model for similar ventures in the State.

The estimated gross potential for land-based grid connected Solar PV in Tamil Nadu is in the range between 4,000 MW and 21,700 MW, according to World Institute of Sustainable Energy (WISE), a Pune-based organisation.

The State government, the official says, is imparting a major thrust to solar power through, among other measures, setting up of solar parks in public-private-partnership (PPP) mode.

Thoothukudi District Tiny and Small Scale Industries Association has welcomed the Solar Energy Policy- 2012 launched by the State government, recently. As per the policy, the government is poised to generate 3000 mega watt solar energy by 2015.

It would certainly benefit the people and small scale traders, and industrialists also would enjoy the benefit, P. Chinnadurai, President, THUDITSSIA, said on Friday. With the advent of the new policy, Tamil Nadu would be in the forefront of solar energy production. Since the southern region of Tamil Nadu has a huge potential for solar energy with almost 300 sunny days every year, solar power through thermal power generation route could be used to produce electricity even during night hours.

Under this policy, high tension consumers would be bound to meet six percent of their energy needs from solar power. However, low tension industrial consumers (SSI units) were exempted. Installation of solar water heaters was made compulsory for industries equipped with boilers and using fossil fuel. Tamil Nadu Energy Development Agency would give a single window clearance to all solar power projects, he said.

THUDITSSIA is contemplating on organising a workshop on solar energy soon and during the schedule all factors relevant to solar energy generation and utilisation would be disseminated, he added.



State Wise DNI and Energy Conditions

Direct Normal Irradiance (DNI)

Direct Normal Irradiance (DNI) is the amount of solar radiation received per unit area by a surface that is always held perpendicular (or normal) to the rays that come in a straight line from the direction of the sun at its current position in the sky. Typically, you can maximize the amount of irradiance annually received by a surface by keeping it normal to incoming radiation. This quantity is of particular interest to concentrating solar thermal installations and installations that track the position of the sun.

 Referring to the DNI alone is not sufficient but one must also take note of the ambient conditions of the particular place.

The average placewise DNI and ambient temperature has been elaborated in the following table:

The solar energy policy unveiled by the State Government has been evoking mixed response among the High Tension (HT) consumers in the district.

Though the initiative to promote tapping of solar energy was widely hailed, the HT consumers are of the opinion that the 6 per cent Solar Purchase Obligation (SPO) (ie starting with 3 per cent till December 2013 and 6 per cent thereafter) mandated in the policy would result in substantial increase in expenditure for them.


“Considering the financial and operational crisis presently encountered by entrepreneurs in sectors like textiles and engineering, it is been requested that the authorities concerned could defer the mandatory obligation of 6 per cent for HT consumers for some more time,” M. Ramaswamy, managing director of Alpine Spinning Mills which is HT consumer.

S. Dhananjayan, an industrial consultant to HT consuming units, is of the view that if at all the 6 per cent SPO need to mandated, the HT consumers going for the solar power generation should be extended incentives/sops to subsidize the capital expenditure for installation of solar power projects at a large scale.


“The prevailing cost of setting up solar power plants of 1 MW capacity comes to around Rs. 9 crore which is a huge sum to bear for people operating spinning mills who are presently starving for funds to meet working capital needs,” he said.

The industrialists are of the view that some of the points mentioned in the policy like exemption from demand cut to the extent of 100 per cent of the installed capacity assigned for captive use purpose and tax concessions were excellent.




Enfinity Solar Solutions Pvt Ltd, a Belgian company, intends to promote a 100 MW solar park in the Coimbatore district. Enfinity’s Managing Director, Guy Baeyens, told Business Line today that the company has two key elements in place – land and approvals for linking to grid.

Baeyens, who believes that the recently-announced Tamil Nadu Solar Policy will help populate the park with developers, said that having land and approvals in hand was a big time saver for those who would put up projects in the park. Enfinity on its own intends to put up a 15 MW solar plant in the proposed park. (A solar power plant typically costs about Rs 9 crore a MW.)

The required land is registered in the name of a Coimbatore-based business house with whom Enfinity is on the verge of entering into a joint venture. Baeyens did not wish to disclose the name of the partner.

For its own project, Enfinity has both equity and debt financing in place. Debt, on non-recourse basis, is from overseas lenders. Baeyens said that Enfinity could help developers in the park raise debt funds abroad.

Enfinity owns 390 MW of solar capacity in Europe-both utility scale and rooftop plants, not counting plants that it built and sold off. In India, the company has so far built plants of a total capacity of 21 MW, for a number of clients including Welspun.

No to thin films

Enfinity will not use solar panels made with the ‘thin film’ technology. This is because, while it is true that thin film modules generate more electricity in hot climatic conditions such as in India, they suffer from ‘thermal breakage’. The modules break in hot summers.

The module manufacturer may replace the modules, but there will be disruption in generation, Baeyens observed.

He said that thin film modules were yet not proven for their long term performance. In contrast, crystalline silicon has performed well for over 35 years, he said.


Enfinity is also offering its services for putting up rooftop solar plants. Baeyens said that the company had rich experience in building rooftop plants in Europe.

Typically, a grid-connected rooftop plant will switch off when the grid power fails. Therefore, the customer does not get solar power when he needs it the most, i.e., when he does not get grid power. However, Enfinity has a technology that will allow the rooftop plant to continue to generate power even if the grid goes off. This is also without the aid of batteries, Baeyens said.

‘DRDA must codify norms for solar power units’

The District Rural Development Agency should evolve and implement a uniform procedure for setting up solar power units, with a view to achieving the State government’s objective of supplementing the growing demand for energy, said a cross section of councillors at the District Panchayat Council meeting held here on Friday. They wanted a coordinated effort to be taken by the district-level officials and block-level rural development officers.

Initiating a discussion, Rajkumar (AIADMK) said Chief Minister Jayalalithaa has been taking serious efforts to tide over the crisis due to shortfall in production. Setting up of solar energy-based installations has been one of the important initiatives in this regard.

He alleged lack of proper guidance on the part of rural development officials in achieving the goals. “Although I have been seeking the procedure for setting up the solar installation in villages in and around Manapparai, the block-level officials failed to coordinate,” he said.

Thangavel, another councillor, intervened to say that the procedure should be codified properly so that panchayat councillors could motivate villagers to set up solar installations.

T. Rajathi, District Panchayat Chairperson, who presided over the meeting, also joined the issue, blaming the officials for their poor coordination in this regard. The procedures stipulated by the block officials were inconsistent with the ones suggested by district level officials.

An official from the District Rural Development Agency assured the councillors that he would advise block development officials to adopt a uniform and hassle-free procedure.

K.P.T. Alagarsamy, a councillor representing Marungapuri ward, pleaded with Forest Department officials to allot a piece of land measuring 100 metres near Oonaiyur for laying a road linking A.Pudhupatti. In the absence of the road, villagers had to circumvent about three km. He also complained about massive damage to crops by wild animals.

V. Ilango, Forest Ranger, Manapparai, said the councillor could submit a proposal to the forest department for transfer of land to Marungapurai panchayat union for providing the road facility. As for checking the animal menace, he suggested setting up of solar fences with approval by the Forest Department.

When a discussion on delay in executing the road over bridge at Manapparai, Oyyamari, Lalgudi and Crawford was taken up, an official from the Highways Department said the general election and by-election last year delayed the process of land acquisition particularly in Manapparai. Steps were now being taken to expedite the work. The bridge at Oyyamari, located on the banks of the Cauvery, involved shifting of water pipelines and electric poles. In fact, the work on construction of the road over bridge at Tiruvanaikovil (which served as a diversion route for vehicles via Oyyamari) would be taken up only after the completion of the work at Oyyamari.

Trichy will soon experience solar power modern bus shelters as their construction, similar to those in New Delhi, has commenced. As many as 18 modern bus shelters and solar power lights will be set up in the city to improve infrastructure.

The construction of four bus shelters began a few days before the chief minister unveiled the 'Tamil Nadu Solar Energy Policy 2012'. Trichy MP P Kumar from the AIADMK has sanctioned Rs 99.70 lakh for both bus shelters and solar power lights from his Member of Parliament Local Area Development Fund.

The fibre glasses on the roof of the bus shelters will generate around 200 watts' power that can be used to illuminate a 11-watt light near the bus shelter. In addition to that, mobile phone chargers powered by solar energy will be fitted in all 18 bus shelters. People henceforth can charge their mobile phones while waiting for a bus.

"The idea came about after I witnessed modern solar power bus shelters in New Delhi. After studying the feasibilities of setting up such structures in Trichy, I identified 18 places and sanctioned Rs 92.5 lakh for bus shelters and Rs 7.20 lakh for solar power lights," Kumar told TOI.

The construction of bus shelters commenced in Karumandapam area where four places have been identified for the purpose. The foundations were dug, but construction was stopped due to rain. However, the contractors have been told to finish the work in two months' time, said the Trichy MP.

The places where the bus shelters will be erected are: four in Karumandapam, two each near government hospital, Ponmalaipatti and KK Nagar areas, and one each at Veereshwaram, Linga Nagar, Thennur, court, head post office, TVS toll gate, G Corner and Anna Statue.

Each bus shelter will be constructed at Rs 4.5 lakh except the bus shelters in K K Nagar terminus and the government hospital, which will cost Rs 9 lakh each. The cost of the bus shelter near Anna statue in Chatram bus stand is Rs 7 lakh.

Students of an engineering college in Dindigul design hybrid auto rickshaw

Efficient use of solar and wind energies are viable alternatives to cut fares

With volatility in petrol prices and other escalating costs, private transport system, particularly autorickshaws, has becomea costly affair.

Now, scaling down autorickshaw fares is a daunting task.

But innovation has answers to all problems.

Efficient use of solar and wind energies are viable alternatives to cut fares and ensure clean and green environment.

The EEE students of PSNA College of Engineering and Technology, Dindigul, have come up with a novel of idea of designing a hybrid autorickshaw powered by solar and wind energy with the additional support of petrol. But they never use petrol to run the vehicle but only to recharge battery.

Now, their novel idea has transformed into a fuel-efficient and less polluting hybrid autorickshaw that can run for about 80 km continuously on full charge carrying four passengers.

It can travel up to 96 km with solar energy and wind energy, an average distance travelled by any autorickshaw in a day.

Fuel emission is cut by 90 per cent.

Excellent team work, relentless research, extensive travel and technical inputs from the street and research institutes has given full shape to their idea.

Briefing about the project, Assistant Professor J.E. Moshe Dayan says that hybrid auto has an internal combustion engine, a switched reluctance motor, wind turbine, photovoltaic system, and an energy storage system.

Plug in charging facility is also available. Various energy sources ensure uninterrupted power supply.

But the auto runs on electric mode, cutting down pollution and ensuring fuel consumption, he adds. “With this, auto driver can save up to Rs.250 a day.”


To achieve this, the team has struggled a lot. It has even burnt its fingers.

The trio – E. Vivedha and Shenbaga Rubini and S. Parvathi – has done wind analysis and computational work while L.S.R. Arun Kumar, G. Arun Kumar, K. Arulselvam, G. Jayamurugan and E.D. Jonesh Kumar have taken care of mechanical design.

“Designing wind turbine drains our time and energy much. First, we designed flat fan propellers. But it did give desired results. After intensive research, we developed sickle-shaped fan blades for drawing more wind,” says Vivedha.

But ME student U.K. Praveen’s efforts has helped overcome the major hurdle of the vehicle’s mechanical simulation.

He only identified high speed and high torque motor manufactured in Kerala costing Rs.90,000 (total project cost Rs.2.5 lakh), she also adds. “It functions well in low power.”

Innovative ideas always get a rousing welcome. The budding engineers receive help from all sides. Industries have happily donated charge controller units, deep-cycle discharge traction batteries and attenuator.

Actually, Dindigul-based mechanic Raju’s contributions has revved up the project to next phase. When the team had worries over over-weight of vehicle due to battery and wind turbines, Raju has fitted car shock absorbers for vehicle stability.

Among top 20 projects

“All our struggles waned when our project got placed fifth among top 20 best innovative projects at Joy of Engineering and Design-innovation (JED-i)-2012, conducted by Indian Institute of Sciences,” says R. Jayamurugan, another student.

This project teaches the faculty that identification of potential and correct guidance will always make students achieve any milestone. It also tells students that true endeavour and tireless research will always help them create history.

    Solar inverter : A business opportunity in India : Enecsys 

    Being one of the first companies to market with micro inverters, Enecsys believes its technology carries several competitive advantages including a life-span that matches that of the photovoltaic (PV) module and the ability to increase energy yield  between five and 20 per cent.

    Enecsys components are manufactured in the Far East and it has aTaiwanese operation as a result of its growth plan.

    Solar inverters are used to convert DC power from the PV cells into AC power for the electricity grid. Conventional devices use 'string' inverters to support a large number of panels, but are generally less efficient and their malfunction can effect the whole panel, unlike micro inverters which support one or two modules.

    Micro Inverters can, however, be harder to maintain, which is why Enecsys has, for what it claims is the first time, eliminated components that limit inverter life.

    The company will continue to work on re-engineering the inverters to drive the cost down further and will use the Series B money to hire staff that can do that.

    The Enecsys IP is based on patented technology developed at the University of Cambridge. The company has previously raised 8.5m, but has no plans for any more according to CEO, Henrik Raunkjaer.

    This last round was led by Climate Change Capital Private Equity who invested 11m and claims it is the largest fundraising round closed this year by any European cleantech company.

    The opportunity is to opt for

    a: Getting a manufacturing and marketing license from them

    b. Just become a marketing agent for India / Asia

    c. Invest in them so that they can start catering to the Indian markets too

    d. Start R & D activities to develop superior products.

    The Central Government has come out with a renewable energy scheme that provides urban local bodies with the capacity to address the power shortage in their areas.

    The entire cost of implementing this project, called Solar City,' would be borne by the Union Ministry of New and Renewable Energy (MNRE). The scheme is being implemented in the State through Tamil Nadu Energy Development Agency (TEDA), S.E.S. Syed Ahamed, Deputy General Manager, TEDA Madurai Region.

    The Centre hoped to achieve the target by providing support for Master Plan for the Solar City. While the total financial commitment for this scheme was Rs.98.50 crore, the Central Financial Assistance (CFA) for Master plan per city was Rs.50 lakh and total financial assistance would be Rs.2.50 crore per city.

    Solar desalination in tn will also be among the top priority ideas like off grid solar in tn, grid connected solar energy in tn, microgrid connected hybrid ie solar cum diesel or solar com biomass etc., Like

    It is interesting to know that TN solar energy is going to compete with Gujarat.Gujarat already claims to be the Germany of solar energy in India. Am eager to see the tamilnadu solar roadmap or the tn solar policy and am keen to hear about land allocation for solar energy and about the capital incentives the tn gov is going to give for solar projects and incentives or subsidiaries for off grid projects and hybrid projects.

    I will be watching this space and I hope Aathmika, Nithya and or Krupali will fill in as and when news happens. 
    If TN gives a healthy competition to Gujarat then India will begin to lead the world in solar as KPMG has alraedy predicted that India will do 67 GW by 2022. Like

    Why is there power shortage in Tamil Nadu?
     Poor long distance vision by officers in the power sector? Spurt in demand for power from  domestic sector?
     Unplanned Industrial growth?
    On one hand Tamilnadu is in the forefront of renewable energy on the other it is suffering from power shortage. The lop sided Renewable Energy Purchase obligation is partly to blame.As per the  Renewable Energy Purchase obligation a certain minimum percentage for purchase  of renewable energy by the state is fixed.;for Tamilnadu it is 11%.
    But the state has an installed wind energy capacity of 35 per cent and production capacity of 12-13 per cent, way beyond the obligatory mark, apart from an impressive biomass potential that is being exploited in a phased manner.
    The introduction of a renewable energy certification, a mechanism that allows producers to sell green energy to states deficit on this front, has resulted in many private players opting for it, say experts.The REC is expected to stimulate competition and create a market for power across states. The producers of renewable energy in Tamil Nadu, by and large private players, find it more lucrative to sell it to other states which have to meet their renewable energy purchase obligations.
    As they are private bodies identity of the end purchasers is unknown.
    Meanwhile, the per capita power consumption in Tamil Nadu, which was 760 units in 2005-06, increased to 1,080 units in 2009-10, a steep jump of 33 per cent, according to TNEDA statistics.But the generation capacity has remained around 10,000 MW and the renewable sector is no different
    Free distribution  of electronic gadgets has partly created this increase in demand.
    Tamilnadu has been in the forefront of wind energy but as for solar TN has much to catch up.

    Wait for Amma to act on Solar power. She will make it the Germany in India as far as solar goes.

    You can surely expect Tamilnadu solar policy soon and it will have the vision that no other state has .

    I need more information on the purchase obligation  of the Governments and utilitites regarding RECs ie renewable energy certificates.

    Jaya hints at a solar surprise to solve the power crisis Chennai: The newly formed AIADMK government is planning to go green' to provide abundant power to the state.

    At a meeting held at the secretariat on Tuesday, Chief Minister Jayalalitha hinted at measures to augment power resources and reduce the inconvenience caused by load shedding. 

    Sources said that her government, in a bid to tap readily available power resources, is proposing to promote solar power. Inspired by the Karnataka government's passion for solar power projects, the AIADMK government plans to create 10 solar energy parks in the state of 300 MW capacities each. The cost of setting up a 1 MW facility is Rs 10 crores, hence it would cost at least Rs 30,000 crore for the entire project.

    The government is planning to get financial assistance from central government and international funding agencies," said a source. Jayalalithaa has also reportedly told government offices in the state to figure out ways of installing rooftop solar plants so they can be off the grid in six months. "Every building will generate 200 kV to 300 kV, which can meet their needs," said the source.

    The project could get a 30% subsidy from the Jawaharlal Nehru National Solar Mission, sources said. The rest of the expenses can be managed using the budget allocated to each government office and funding by the state government. "Billions of units of Tamil Nadu Electricity Board (TNEB) power can be saved if all the offices go solar," said a senior government official.

    As part of its efforts to promote solar energy, the Tamil Nadu Electricity Regulatory Commission (TNERC) has proposed a minimum quantum of solar renewable purchase obligation (RPO) in the overall renewable purchase obligation of the State.

    According to the draft notification published on the Commission's website, the share of solar energy has been mentioned as 0.15 per cent of the total RPO in terms of energy in kilowatt per hour (KWH) for the year 2011-2012. For the next two years, it will be 0.25 per cent.

    The norm, when approved by the Commission, will essentially be applicable to the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) even though it will cover users owning captive generating plants and open access consumers in the State. The Commission has sought comments from stakeholders on or before June 20.

    As far as the overall RPO is concerned, the State has already fulfilled the national norm of 10 per cent, in view of a large number of windmills. The total RPO is 14 per cent but the share of solar energy in the total RPO is negligible.

    So far, only the private sector has evinced interest in putting up solar energy plants.

    Now, one five-megawatt (MW) plant is functioning in the Sivaganga District. This is a grid-connected plant, which is a solar photovoltaic (SPV) unit. Besides, under the Jawaharlal Nehru National Solar Mission, seven plants of one MW each have been approved. Officials say two plants, one each in Sivaganga and Nagapattinam Districts, are expected to be commissioned in a few months. Other districts include Tuticorin and Virudhu Nagar.

    In addition, under the bundling scheme' of the mission, one plant of 5 MW has been sanctioned and this will also come up in Tuticorin district. The bundling scheme' envisages the nodal agency, NTPC Vidyut Vyapar Nigam, to bundle solar power from the identified project promoters with power from the cheaper unallocated quota of the Union Power Ministry and sell it to distribution utilities. According to the TNERC's order in May 2010, the capital cost has been put at about Rs.17.16 crore per MW for a solar PV project. The solar power tariff for 25 years has been worked out at Rs.18.45 per KWH.

    The government is likely to come out with a solar power policy aimed at generating about 1,000 MW power by encouraging city residents across the state install solar panels atop their houses, especially multi-storeyed buildings. However, it is not likely to be made compulsory. The government is also working on a policy to encourage all dairy farms and poultry farms in the state generate biogas.

    The state cabinet, which met on Monday, discussed the issue and the nitty-gritty is being worked out. Since installation of solar panels is an expensive proposition, the government is chalking out a comprehensive package, officials said. The central government is already providing 30% subsidy for solar plants. The state government is planning to subsidise it further to make it attractive for consumers.

    The Central government has come out with a renewable energy scheme that provides urban local bodies with the capacity to address power shortage in their areas.

    The entire cost of implementing this project, Solar City,' would be borne by the Union Ministry of New and Renewable Energy (MNRE). The scheme is being implemented in the State through Tamil Nadu Energy Development Agency (TEDA), S.E.S. Syed Ahamed, Deputy General Manager, TEDA Madurai Region, told The Hindu here on Sunday. The TEDA Madurai Region comprises 11 southern and central districts.

    The Central government has been motivating not only people but also State governments to aim in reduction in use of conventional energy sources thereby compensating with renewable energy. The ministry aims to set up a maximum of 60 such Solar Cities, at least one in each State, he said.

    The Centre hoped to achieve the target by providing support for Master Plan for the Solar City and organising programmes on renewable energy.

    While the total financial commitment for this scheme was Rs. 98.50 crore, the Central Financial Assistance (CFA) for Master plan per city was Rs. 50 lakh, and the total financial assistance would be Rs. 2.50 crore per city.

    As pilot projects, 10 cities would be covered in the 11th Five Year Plan on a first-come first-served' basis. In Tamil Nadu, Coimbatore had been chosen. Urban local bodies with a population of 50,000 to 50 lakh could apply for this project through TEDA. The project would require details such as total number of streetlights and other areas of energy consumption in the target area.

    The Solar City project would focus on devices such as solar systems like building integrated photovoltaic systems, kitchen waste-based plants, solar water heating systems, solar cooking systems, solar steam generating/drying/air heating systems, solar concentrators for process heat applications, solar air-conditioning, power projects on methane recovery from Standard, Temperature and Pressure (STPs) condition, bio-mass gasification based-systems and biogas, besides wind.

    Mr. Syed said that TEDA was making efforts to bring in more cities under this scheme as a way to tackle the power crisis in the State.


    Speaking about the development of solar energy in southern districts of Tamil Nadu, he said that TEDA had identified around 200 beneficiaries in Kanyakumari district to provide solar home lighting system free of cost under Part II' scheme at a cost of Rs. 45 lakh.

    The entire project was being borne equally by the State and Central governments. This project would be undertaken shortly so as to electrify villages that have not had electricity for over 50 years in the forest areas of the district, he said.

    Jayalalithaa has asked the Prime Minister to provide funds for the utility-scale plants as well as the streetlights under Jawaharlal Nehru Solar Mission. She has requested support under national clean energy funds for the path breaking initiatives undertaken by the Tamil Nadu government.

    However power managers state that getting such a huge amount may not be possible as solar power promotion is spread across the country. "The centre will have to answer in the parliament on how it gave such a huge amount to one state. Besides, she has asked for another Rs 40,000 crore to bail out TNEB from losses," said a source.

    Experts say that it may be possible to implement the project successfully if the government goes in for a public-private partnership model. "In this case, the state government need not worry much. It can get subsidy from the central government. Private companies will come up with the funds," he said.

    Moser Baer Solar Ltd (MBSL) has said that its solar modules are now certified by TV InterCert for being corrosion resistant. 

    "This certifies not only enhanced overall reliability of MBSL's PV modules but also their suitability for a 25 year deployment in the coastal regions like Gujarat or Tamil Nadu and in areas like Kutch with a high level of salt content in air, rain or soil for the most part of the year," the company said in a statement. 

    According to various reports, Gujarat itself is looking at commissioning more than capacity 500 MW of solar installations this year and thereby creating a demand for PV modules that are resistant to corrosion when exposed to salt content in the air, it said. 

    "This certification significantly addresses the needs of solar developers in India and will improve the confidence of investors in the solar PV projects," the company said. 

    It said that the "salt mist" corrosion resistant certification complements company's 25 years' warranty on its PV modules are already bankable with more than 20 banks in Europe. 

    Globally, banks and financial institutions prefer PV projects that use highly reliable PV modules and since the 'salt mist' corrosion resistant panels improve the viability of solar projects even in demanding climatic conditions, it will have a positive impact on the bankability of solar projects commissioned using the same, the statement said.

    The State Government also sought Rs 45,000 crore from the Centre for solar power generation projects. Ms Jayalalithaa said Tamil Nadu plans to set up 10 solar energy parks of 300 MW each to strengthen power generation. It also hopes to provide solar powered street lights in villages under the Jawaharlal Nehru Solar Mission and supply solar power to households below the poverty line. Funds could be provided under the National Clean Energy Fund, she said in the representation. The JNNSM seeks to set up 1,000 MW of solar power through the Ministry of New and Renewable Energy in the first phase. In Tamil Nadu seven developers have been given permission to set up 1 MW each. The Chief Minister urged the Central Government to expedite the Central power generation projects now under implementation in the State. Like

    This is good news for the people of Tamilnadu. Apart from the heavy focus on boosting the solar power generation in TN, the government has proposed 3800 crores for 100% evacuation of the solar generated power which is the most important.

    Like TN being one of the biggest producer of wind power failed to invest in wind power evacuation systems which resulted in huge loss of power generated and financial loss to the investors.

    Tks Nithya for the post.

    TNEB has an accumulated loss of Rs 40,300 crore and an annual deficit of Rs 10,000 crore.

    The era of rationalisation has arrived. Diesel, Petrol, Cooking gas are all getting rationalised. The prices are tied up with international rates of crude.

    Thank God ! Electricity rates cant have the same rule. Atleast it is not going to be the same as in California. Which is supposed to be near 25 cents per unit. ( pl Chk).

    But rates are going to go up for all of us. 

    Rates for commercial usage is going to go up.

    In residences it will go up for those who use more .

    In residences and in commercial establishments the rates / tariff will go up during peak hours.

    Even if the tamilnadu government doesnt attempt at collecting the Rs 40,300 crores it will atleast attempt at minimising the yearly losses of 

    Rs 10,300 crores. This is unlikely to affect those consume below 200 units per month. 

    This is the only way TN can get ready to pay for Solar energy generation by private parties. 

    If the tariff for the industries go up, the industries would rather go up for captive power generation using solar energy and biomass energy.

    Thus the era of the solar energy arrives in Tamilnadu. For that matter it is going to be the case in rest of India.

    This can have a cascading effect with inflation. For industrial products.

    HOwever the farmers will be a little better off as they will have some dhothi money ( instead of pocket money) when they sell biomass.

    Compared to neighbouring states, Tamil Nadu has the lowest power tariff, one that has remained untouched for more than 10 years. The only recent spike in tariff came in 2010 for some segments like cinema theatres and commercial establishments. 

    Due to this, TNEB has been stuck in monetary quicksand, forcing chief minister J Jayalalithaa to appeal to the Centre for financial assistance.

    The government now seems to have realized that tariff revision is the only way out to save the ailing TNEB. "The electricity board has been asked to submit a proposal for the hike. They will study how much to hike the tariff and for what segments," a government official told TOI. 

    The report is expected to spell out exactly the amount the board proposes to raise, the various segments that have been causing losses and a comparative study of the cost per unit of electricity in other states.

       Word has it in the second phase of JNNSM  import of solar cells, modules is to be restricted.Local players should benefit from India's growth in solar energy. Zynergy is an early bird who has realised that  Both economics and import restrictions make the establishment of an incountry facility to assemble and manufacture solar panels very attractive. 
         Zynergy now has the support of the Government of Tamil Nadu to build a plant with an initial capacity of some 25MW per year, with the potential to increase capacity to 350mW per annum. The plant will be sited in Nanguneri, in the very south of Tamil Nadu, in a Special Economic Zone (SEZ), which enjoys significant fiscal and other incentives.   Like

    Presenting the AIADMK government's first budget Thursday, Finance Minister O. Pannerselvam said the government plans to energise 20,000 street lights in 200 villages at a cost of Rs.49.60 crore. 

    He said the subsidy from the central government will be Rs.11.20 crore and the balance will be funded by the state government. 

    Referring to the government's plan to build 60,000 green houses this fiscal, he said Tamil Nadu Energy Development Agency (TEDA) will take up the energisation of the houses with solar power at an outlay of around Rs.180 crore. 

    Pannerselvam said the central government subsidy will be Rs.48.60 crore and the balance will be met by the state government. 

    'As a part of the government's commitment towards green energy, it is proposed to establish initially a 50 MW solar park in PPP (public-private-partnership) mode through competitive bidding process,' Pannerselvam said.
