Domestic consumers who are beneficiaries of the Chief Minister’s scheme for solar rooftop capital incentive can hope to have the installation of solar photovoltaic (SPV) systems early.

Twenty five systems have been installed. The delivery of the first set of bidirectional (net meters) meters is expected shortly and the meters will also be installed soon, according to Sudeep Jain, Chairman-cum-Managing Director, Tamil Nadu Energy Development Agency (TEDA), the nodal agency for the scheme.

[Bi-directional meters are required as solar energy produced at the end of the consumer is more than the consumption, the surplus energy will automatically be exported to the Tamil Nadu Generation and Distribution Corporation (Tangedco) distribution network or the grid. If there is less solar energy than what the consumer requires, the shortfall will be drawn from the grid (energy import). Such meters alone can measure both energy import (from the grid to the consumer) and energy export (from the consumer to the grid). They will replace the conventional meters at the premises of beneficiaries of the scheme].

Responding to questions on the status of implementation of the scheme, Mr. Jain told reporters on Monday that sanction had been given for 1,500 consumers. Totally, 10,000 consumers could be covered under the scheme.

As regards the execution of the Chief Minister’s Green House Scheme, the CMD said 90,000 houses had been provided with solar power systems. The installation of the systems was possible only when houses were completed and normally, there would be a gap of six months.

As for solar-powered street lights, 20,000 street lights had been installed. Initially, the lights were installed in a cluster of 10 followed by 15. A pilot project was under way in Kancheepuram district to install grid-tied 50 street lights.

Renergy 2014

Referring to the installation of a large number of solar power systems in the State every year, the CMD said this underscored the need for skilled manpower, both at the time of installation as well as for maintenance. This issue would be addressed at the upcoming international conference and exposition on renewable energy, “Renergy 2014,” by having a pavilion meant for career prospects in renewable energy and skill development. About a dozen companies were expected to be part of the pavilion. The meet would be held during June 12-14 at the Chennai Trade Centre here. On June 12 and 13, general visitors would be allowed between 3 p.m. and 6 p.m. while the entry would be permitted throughout the day on June 14.

BESCOM to implement Net Metering Infrastructure??: Rooftop Boom in Bangalore??

The Bangalore authorities have already started work on net metering to enable individual households to put solar panels on their rooftops and sell extra solar electricity to the Bangalore Electricity Supply Company Limited (BESCOM).The company will soon provide its consumers with rooftop solar units to contribute to power supply and also gain from it.

BESCOM implementing net metering system for solar rooftop panels

In this regard, BESCOM has invited bids from manufacturing firms who are in the field of manufacturing bidirectional (DLMS protocol) (single phase, three phase, CT operated) meters.Under the Karnataka Solar Policy 2013, solar power consumers can sell excess power they generated to BESCOM.When usage of power is minimal during day, electricity generated through solar panels can be supplied to the power grid, and, in the evening, when power is needed in larger quantity, consumers can draw power from the grid.Consumers will be paid for the difference of electricity used and supplied. more..

 

Net metering gets a big boost from the government in Andhra 

 

The second phase of solar energy system at the Raj Bhavan was launched by governor ESL Narasimhan on Monday.

 

Taking into consideration the net metering policy, officials installed a 20 KWp solar roof-top photo-voltaic system which was connected to the grid.The total project cost was Rs 18.50 lakh and the project is eligible for central financial assistance of Rs 5.55 lakh. The net investment by the state is Rs 12.95 lakh. The work, entrusted to Fourth Partner Energy, was completed in a record time of seven days.The system will generate 90 to 100 units a day and 29,000 units a year. The power will be utilised to meet the requirements of Durbar Hall and any excess power will be injected into the grid and adjusted in the monthly energy billing. more..


 

 

IET launches first white paper on Net metering in India

 

The Institution of Engineering and Technology (IET) India Solar Panel, a volunteer-led visionary think tank in the solar energy sector providing unbiased recommendations in the areas of solar energy policy, regulations and technology, released its first whitepaper in India today. The whitepaper, titled Recent developments in Net-Metering in India and the Way Forward, presents the most recent developments in the net-metering scheme for small scale solar projects across India and also analyses the case when Renewable Energy Certificates (RECs) are availed by consumers owning roof-top solar systems. 

A key insight of this whitepaper is that RECs availed by consumers under the current framework  will lower the market performance, which is already marred by the poor enforcement of Renewable Purchase Obligation.Net-Metering, a billing mechanism that credits solar energy system owners for the electricity they add to the grid, allows consumers to directly contribute to enhancing the renewable energy capacity of the country by availing of state and government subsidies that are in force. Recently, the need for fostering small scale renewable energy projects in India has been on the rise and both the Centre as well as individual State governments have started putting concerted efforts to bring in relevant policy frameworks. more

MNRE to install solar power plants in all govt buildings??

The Ministry of New and Renewable Energy (MNRE) is promoting installation of solar systems in all buildings, depending on the feasibility, willingness of users and availability of funds. 

Under off the grid and decentralized solar applications scheme of Jawaharlal Nehru National Solar Mission (JNNSM), the ministry provides central financial assistance of 30% of the cost of solar systems for installing solar PV and thermal systems at educational institutions, hospitals, police stations, panchayats, jails, government guest houses, community buildings, Anganwadis, orphanage and other buildings for social and community use, etc

For special categories states viz. NE, Sikkim, J&K, Himachal Pradesh and Uttarakhand, remote and difficult areas such as Lakshadweep, Andaman & Nicobar Islands, and districts on India's international borders the CFA is limited to 60% of the cost of the water heating systems and 90% of the benchmark cost for SPV power projects accessed by only State Nodal Agencies (SNAs) / Solar Energy Corporation of India (SECI) . The benchmark cost set by the Ministry ranges from Rs 100 /Wp to Rs 450/Wp depending upon the size of the SPV system and Rs.8500 to Rs 11000 per sq. meter of the collector area based on the type of the collectors. 

A total of 10,847 numbers of standalone and decentralized solar PV power plants aggregating to 22.85 MWp capacities have been installed on union and state government buildings in the country till December, 31, 2013. more...


 

 

 

Net metering to be promoted in a big way : Andhra

 

 

If the exorbitant electricity bills make you twitchy, there’s a way out. You can not only offset the cost of your electric use but also make some additional moolah.

Net-metering is the answer to your problem. To embrace the new concept, one must have a rooftop solar power plant not only to generate electricity but also to sell the excess power generated by your solar panels back to the distribution company’s grid.

Campaign

“Net-metering is the latest mantra and we are trying to promote it in a big way. The lucrative idea of ‘exporting’ the surplus electricity back to the grid companies for a price seems to have caught the fancy of electricity consumers and this tendency reflects in the good response we are getting,” New & Renewable Energy Development Corporation of Andhra Pradesh (NREDCAP) District Manager K. Srinivasa Rao told The Hindu.

The department has kicked off a campaign to popularise the new device in domestic and non-domestic sectors. Besides conducting meetings, it distributed about 10,000 pamphlets. It has approached banks asking them to extend loans for purchase of the solar plant. “The Vijayawada Municipal Corporation has applied for 500-kw, which it intends to install at five different places. We are also trying to motivate educational institutions to opt for this model,” he says.

A consumer producing solar electricity at home by using solar panels can opt to give excess remainder of the energy back to the grid. “This will spin the electric meter backwards giving the consumer a credit for that net energy transferred back to the grid. It is a kind of banking one’s own energy for later use or sharing for credits,” explains Mr. Rao.

Incentives are offered to motivate consumers to produce renewable energy through their home solar power projects. A plant with a capacity of generating up to 3 kw is entitled for a 50 per cent subsidy.

The surplus energy fed back into the grid will be considered for payment by the Discom at pooled cost decided by the APERC.Courtesy:Hindu


 

KERALA SOLAR NET METERING POLICY: OFFICIAL DRAFT

Notice is hereby given that Kerala State Electricity Regulatory Commission has published the Draft Kerala State Electricity Regulatory Commission (Grid Interactive Distributed Solar Energy Systems) Regulations, 2014. Stake holders including public are requested to forward their comments/ responses on the draft regulations, to the Commission on or before 28-02-2014. The stake holders and the public can present their responses/comments on the draft regulation in the public hearing also which shall be held at 11 AM on 19.03.2014 at the Office of the Commission.

Official Document 

Kerala NetMetering policy

  • The policy does not set an upper cap on amount of energy that can be banked. The net metering policies of Delhi and Tamil Nadu – both suggest a maximum cap of 90% of the consumer’s energy requirement in a calendar year. The policy also prescribes that the DISCOM shall pay the consumer the Average Pooled Purchase Cost (APPC) of INR 1.99/kWh for the excess energy injected onto the grid after the banking settlement – a first inIndia. This is perfect for consumers that want tocapitalize on excess rooftop space. No longer shall such consumers be limited by the maximum energy that can be injected onto the grid.
  • This policy has a first of its kind ‘sharing concept’ wherein a consumer that has several premises across the state, can install a solar plant on one location and wheel the excess power to the other locations. Although, this entails a wheeling charge of 5%, this is a perfect opportunity for IT companies, textile mills and other retail outlets that may have multiple locations in the state. This way, the consumer can optimize on the ideal rooftop space and minimize installation and maintenance cost.  
  • From the DISCOM’s point of view, all energy generated from solar plants registered under this policy shall be considered to meet the DISCOMs Renewable Purchase Obligation (RPO).

Technical details

  • The policy limits system sizes to 3 MW
  • The policy suggests the following grid connectivity voltages across different solar system sizes
  • The connection voltages are as follows:
    • System size of 5 KW or under tobe connected at 240 V (single phase)
    • System size of 100 KW or under to be connected at 415 V (three phase)
    • System size of 3 MW or under tobe connected at 11 KV Courtesy Bridge to India

 


Global smart meter installations to top 800 million by 2020

Smart meter revenues will grow to $7.4bn (£4.5bn) in the next four years from $5.2bn in 2012, according to a report from Telefonica published late last week.

Asia and Europe will be major drivers of market growth, the report stated, predicting that more than 800 million smart meter devices will be installed worldwide by 2020.

Telco giant Telefonica, which is a communications provider for the UK Government's smart meter programme, said that 80 per cent of European households will have smart gas and electric meters installed by 2020, thanks to regulations there that are driving deployment of the technology.

Today, the penetration rate for smart meters in the region is already about 17 per cent and Europe is expected to catch up with North America, which currently has the highest rate of deployment.

The report, entitled The Smart Meter Revolution, also predicts Asia will lag slightly behind the US and European markets, but high demand in China is expected to drive penetration to almost 70 per cent by 2022. In Japan, the growth wave is just beginning, the report added, predicting tens of millions of smart meter devices will be installed by the next decade.

However, the report expects that the Middle East and Latin America will drag down global average penetration rates due to lacklustre uptake.

Significantly, smart meter revenues will begin declining from 2018, said Telefonica, as unit prices drop and installations dwindle.

The report also issued a note of caution about the potential for media campaigns and public scepticism to undermine adoption of the technology.

"Some consumers remain sceptical and are resisting the idea of smart metering," it noted. "Though relatively few in number, vocal consumer groups in Europe and North America cite concerns about meter accuracy, data security and health."

The report emerged just days after a survey from British Gas, which revealed that a third of smart meter customers in the UK were saving up to £75 per year. Nine in every 10 respondents to the survey said they were making some savings on their energy bills thanks to the metering technology, which feeds data on energy usage back to energy companies, and often displays it to users in the home, providing them with a frequent reminder to tackle energy waste. more..


 

GUJARAT LAUNCHES SOLAR NET METERING POLICY : SOLAR ROOFTOP MARKET SHINES IN GUJARAT

 

In order to provide the necessary fillip roof-top solar power projects sector in Gujarat, the state government will be introducing a new "net-metering policy" in 2-3 weeks, that will provide better financial incentives to solar-power generating households.

"We have prepared this policy and we hope to declare it before the Lok Sabha elections are announced," DJ Pandian, principal secretary (energy), Government of Gujarat told The Indian Express on the sidelines of a seminar on "Solar Energy in India' organised by the Ahmedabad Management Association (AMA) on Saturday. Courtesy


 

DELHI INVITES BID FOR SOLAR NET METERING

 Delhi Electricity Regulatory Commission has invited suggestions and feedback from stakeholders on a proposal to introduce net metering for rooftop solar power generation as per guidelines laid down by the ministry of new and renewable energy. 

The commission claims that, with about 300 sunny days in Delhi a year and around 30 lakh households, Delhi has more than 700 sq km of built-up area for installation of photo-voltaic systems. With net metering, the commission will be able to keep an account of how much self-generated solar power the consumer will retain, how much they will pass to the distribution grid and how much they will draw from it.

ANDHRA GETTING READY FOR SOLAR ENERGY NET METERING

 

The Andhra Pradesh Southern Power Distribution Company Limited (APSPDCL) is gearing up to implement net metering policy. It is about the mechanism of injecting solar power into the grid by rooftop and small photovoltaic plants and arriving at the net value of power. 

Bi-directional meters 

On their part, the Discoms are mandated to certify and inspect the solar rooftop systems along with the metering devices and other paraphernalia at regular intervals while the NREDCAP facilitates payment of subsidy to the consumers registered with it. Installation of high accuracy bi-directional meters which can be tracked on a real-time basis and devices capable of injecting solar power into the grid smoothly without causing fluctuations in the grid frequency are the main things that the APTRANSCO and Discoms have to do.

 Disturbances 

Disturbances (harmonics) to the grid are common as direct current (solar energy in this case) is converted to alternate current. Insulating the grid from such variations is called ‘island protection’.COURTESY

  *NET METERING CONCEPT INAUGURATED : AP ROOFTOP SOLAR  

Eastern Power Distribution Company of AP Limited (APEPDCL) in association with New and Renewable Energy Development Corporation of Andhra Pradesh(NREDCAP) on Saturday launched net metering, an eco-friendly concept of encouraging power consumers to take to solar power production to manage the energy demand and supply.more..


 

*AP GEARS UP FOR SOLAR NET METERING POLICY : ROOFTOP SOLAR POWER

 The state energy department on Friday said citizens going for roof top solar power generation could get their system connected to the grid or remain off the grid.

While in the first option the power generated by the solar panels will be directly injected to the grid and requires no battery storage at the consumer end unlike in off-grid solar power units. The subsidy, however, would be extended to both the options, according to M Sahoo, Principal secretary of the energy department.more

 


 

 *CHANDIGARH TO HAVE BI-DIRECTIONAL METERS SOON!!

 

A solar generation unit costing around Rs 1 lakh could soon not only light up your home, but also trim your electricity bill if you are able to generate excess power.

In a unique proposal, residents could export solar power to the electricity department and balance out their power bill. However, they won't be able to earn money with commercial use of the system.

Santosh Kumar, conservator of forest and wildlife, UT, said the system has been experimented at government buildings in the city and would be extended to houses after receiving approval from the Joint Electricity Regulatory Commission. "The attempt is to promote zero electricity usage in most houses with a majority of electricity being drawn fromsolar energy," he added.

Power generated from solar panels during daytime could be utilized fully by lighting up the house and feeding excess power to the grid. A team of UT officials recently visited Germany to study solar generation system, preparing a report on features that could be easily replicated here.

However, the hurdle was that in existing meters, needles could not move in reverse direction when solar power generated from home was exported to the grid. To tackle this problem, UT has now filed a petition with Joint Electricity Regulatory Commission to get permission to install "bi-directional" meters.
The system of smart meters has been introduced in Andhra Pradesh and West Bengal but since there is no policy at the national level, it depends on the initiative of the states.more..

 WHAT IS NET METERING?

  • Net metering allows electricity generated from solar power to be fed into the grid.
  • It allows users to get power credits for the electricity fed into the grid

  http://www.seia.org/policy/distributed-solar/net-metering

  • It encourages users to use small scale renewable generating system.
  • Net metering consumers are charged only for the 'NET' electricity consumed

http://www.serconline.org/netmetering/  

  • Net metering is resource management and payment scheme in which a user can feed power into the grid and is compensated with credits 

http://searchcio.techtarget.com/definition/net-metering  

  • Net metering is a policy for customers who own renewable energy sources. Under this policy the user gets power credits for at least a portion of the power produced.

http://en.wikipedia.org/wiki/Net_metering

  •  At any time of the day, a customer's solar system may produce more or less electricity than they need for their home or business. When the system's production exceeds the customer demand, the excess energy generation automatically goes through the electric meter into the utility grid, running the meter backwards to credit the customer account. At other times of the day, the customer's electric demand may be higher than the renewable energy system is producing, and the customer relies on additional power needs from the utility. Switching between solar system's power and the utility grid power is instantaneous-customers never notice any interruption in the flow of power.

NET METERING IN ANDHRA PRADESH


 

 WHO CAN USE NET METERING?

  • Electricity consumers who have their own renewable energy facilities

http://en.wikipedia.org/wiki/Net_metering

  • All those who produce surplus power and want to monetize can use net metering. In the case of households, they may not use all the solar power that they generate during day time and want more power during  night times. Similarly, factories may not want renewable power that they generate during the weekends and would want more power during weekdays.
  • It is used by houses,schools, factories etc to reduce the electricity bills.

http://protectnetmetering.org/learnmore/what-is-net-metering/

 


 

HOW DOES IT WORK WITH SOLAR PV?

 

  • Based on available roof area solar PV panels will be installed on the roof of the building.  The output of the panels (DC electricity) connect to the power conditioning unit /  inverter which converts DC to AC. The inverter output will be connected to the control  panel or distribution board of the building to utilise the power. The inverter  synchronises with grid and also with any backup power source to produce smooth power  to power the loads with preference of consuming solar power first. If the solar power is  more than the load requirement, the excess power is automatically fed to the grid. For  larger capacity systems connection through step up transformer and switch yard may be  required to feed the power to grid. 
  • First the DC current is converted to AC to meet the frequency of the grid. When excess power is produced is injected into the system, the meter runs backward instead of forward. Hence the meter runs in both directions and is called bi-directional meters.
  • If you want a net metering billing arrangement, your generating equipment must be connected to the local electric utility’s distribution system. Whenever your generating equipment produces more electricity than you need, the extra electricity flows backward through the utility meter on your property making it turn in reverse. This reverse metering may result in a lower monthly meter reading by the electric utility, thus lowering your electric bill.

WHAT ARE METER SPECIFICATIONS OF NET METERS IN INDIA?

 

   0.2 class accuracy, tri-vector based energy meter, non ABT having the MRI  downloading facility along with related accessories shall have to be installed by  the SPV generator . The SPV generator shall bear the entire cost of metering arrangement  provided including its accessories.   

 


 

 

HOW TO DO THE BILLING FOR SOLAR NET METERS IN INDIA? 


The SPV generator shall pay for the net energy in a billing month as per  applicable retail supply tariff decided by regulatory commission to the  concerned Discom, if the supplied energy by the licensee is more than the  injected energy by the solar PV sources of the consumer(s).  Any excess/ surplus energy injected in to the grid in a billing month will be  treated as inadvertent and no payment will be paid for such energy. Spot billing is to be arranged by concerned ADE/Opn as per the billing  period. Discom shall arrange to develop suitable software and incorporate in the  billing instrument for such billing.  

Under a net energy metering agreement, your utility will continue to read your meter monthly and you will receive a monthly statement indicating the net amount of electricity you consumed or exported to the utility grid during that billing period. If you are a residential or small commercial customer, you have the option of paying the utility for your net consumption monthly, or settling your account every 12 months. Contact your utility for billing options.Courtesy : Gosolar california


 

 

 IS PROTECTION REQUIRED? 

 

  The SPV generator is required to provide an appropriate protection system on  their incoming side / consumer premises with the feature of “Islanding the SPV  generator” when grid fails. Protection system including its switch gear has to be certified by  concerned DE/MRT.Further, harmonic suppressive device has to be installed by such SPV  generator to suppress the harmonics injection as harmonics is more in case of  solar plants where conversion of DC to AC is taking place.

 COST OF A NET METERS, BI DIRECTIONAL METERS IN INDIA 

 

  • The net meter box cost around $10-15 that is about Rs 700-1000
  • Two metering system may cost more.
  • The wiring cost is seperate. It may vary from place to place depending on distance of box to the panels.

 EFFICIENCY OF THE NET METERS IN INDIA

 

  • Digital net meters are higly efficient when compared to the conventional disc type meters
  • There can be problems in the display values, which is often corrected.

 


 ADVANTAGES OF SOLAR NET METERING IN INDIA

  • Most important advantage is that we can inject excess power from the panels to the grid.
  • Net meters also provide information on energy saved by the system
  • It calculates 'power credits' on power injected into the grid
  • It encourages us to save power using 'Time of Use ' and other unique features present in modern net-meters
  • It reduces the pressure on the grid.
  • Power can be also provided to neighboring homes
  • It reduces transmission losses.
  • It makes the user more conscious of energy usage

HURDLES TO OVERCOME FOR NET METERING

  • Roof top is more expensive than large grid connected power
  • Consumer pay for electricity depending on the usage.Even the highest tariff slabs do not cost as much as small scale PV generation
  • Improper net metering infrastructure
  • Not enough net metering manufacturers
  • No performance Guarantee
  • unskilled man power for fixing and maintenance
  • Grid compatibility 
  • Lack of proper monitoring may occur
  • Many paper work issues
  • Taking money from the govt has always been a problem (if we provide excess power to the grid)

 AP NET METERING ORDER

 

Solar power policy pressnote.

The Government announced its policy for encouraging solar power production in the State. A GO MS NO 22 to this effect has been issued on Monday. Keeping in view the good potential for harnessing solar power, it was felt that net metering facility be provided to the consumers to generate solar power for self-consumption and feeding excess power into the grid when it is not being consumed by them.

It may be recalled that the APTRANSCO has already installed 100 KW solar plant at Vidyut Soudha, Hyderabad on a pilot basis and is following the net metering facility. The Chief Minister Mr N Kiran Kumar Reddy has recently visited Vidyut Soudha and personally seen the functioning of the solar plant.

As per the new policy, net metering facility will be implemented for the consumers who intend to encourage solar green energy and set up solar PV plants at unutilized places on roof-tops, waste lands, buildings of individual households, industries, offices, institutions, residential complexes etc. Subsidy will be provided by the Government of India through NREDCAP up to 30% of the cost the panel up to a capacity of 500 KW without battery support. 

Implementation of this facility will be as per the following guidelines:

I. Under this facility, consumer will generate solar power for self consumption and feed excess power into the grid. 

II. Net metering is the concept which records net energy between export of generated energy and import of DISCOM energy for a billing month. Alternatively, the meter, having the feature of recording both the import and export values, besides other parameters notified by CEA metering regulations and APTRANSCO /DISCOM procedures in vogue, shall also be allowed for arriving net energy for the billing period.

III. The net metering facility shall be allowed only for 3 Phase service consumers. Single Phase consumers are not eligible for net metering to avoid imbalance in the phases.

IV. The SPV generator shall pay for the net energy in a billing month as per applicable retail supply tariff decided by regulatory commission to the concerned DISCOM, if the supplied energy by the licensee is more than the injected energy by the solar PV sources of the consumer(s). Any excess/ surplus energy injected in to the grid in a billing month will be treated as inadvertent and no payment will be paid for such energy.

V. The SPV generator is required to provide an appropriate protection system on their incoming side/ consumer premises with the feature of “Islanding the SPV generator” when grid fails.

VI. The SPV generator shall bear the entire cost of metering arrangement provided including its accessories. The installation of meters including CTs & PTs, wherever applicable, shall be carried out as per the departmental procedures in vogue with prior permission of DISCOMs.

VII. Such SPV generator will submit the required information in the prescribed format to the DISCOM & DISCOM will give acknowledgement for the same for the net metering as per the applicable billing period.

VIII. The Solar PV panels proposed to be installed shall meet the requirements of Indian as well as IEC standards.

IX. They can avail any prevalent subsidy offered by Government of India in this regard.

 

Guidelines for implementation:

  • Only for 3 phase service consumers. Single phase consumers are not eligible.
  • Consumer will generate solar power for self consumption and feed excess power into the grid.
  • The meter records net energy between export of generated energy and import of DISCOM energy for a billing month. Alternately, it can record both the import and export values and the net energy for the billing period can be calculated.
  • In a billing month, if there is a net import you pay the applicable retail supply tariff decided by the concerned DISCOM. If there is a net export, you wont get paid for it.
  • The consumer/SPV generator also has to set up a protection system on their premises with “Islanding” for events like grid failures
  • The entire cost of metering arrangement and accessories are to be paid by the consumer.
  • The consumer needs to submit information to DISCOMs to get acknowledgement for net metering as per the billing period.
  • The solar PV panels to be installed should meet Indian and IEC standards
  • Any prevalent subsidy from Govt of India can be availed.

 

So, what this policy means is that -

The consumers can generate solar power for self-consumption. The excess power, when it is not being consumed, will be injected into the grid but the government will not pay for it. This policy would only serve in aiding of infrastructure setup for any future policies that might offer a tariff for injected power.

It would be preferable to have a solar policy that offers a tariff for excess energy exported to the grid. Even better if it offers a higher tariff since it is green energy that is being generated. That would give incentive to the consumers to set up larger capacities and utilize most of their available unused rooftop and waste lands in their premises. That’s something to look forward to.

Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO) submitted a document with detailed procedure (draft) for Net metering. Following are the important points covered in this document:

Location of meters: 

  • Two meters are to be installed. First one for measuring solar generation is to be installed at the generator end after the inverter. The point of solar power injection may be in between the load and the second meter, i.e. Import/Export (Bi-directional) meter
  • Consumer has to bear the cost of both the meters
  • The Solar policy encourages hybrid generator and in this case, separate sets of meters have to be adopted at the rooftop solar SPG (Solar Power Generator) and WEG (Wind Energy Generator ) ends
  • A new type of meter card to be provided with the facility to incorporate both the assessor’s and consumer’s initials along with the details of the generator’s bank account number to which Generation Based Incentive (GBI) would be credited at the end of the billing month

Tariff for excess generation:

  • Currently there is no tariff rate for excess generation/Export of solar power. Commercial consumers will be allowed power credits only whereas, Domestic consumers will be allowed both GBI and power credits
  • In the case of import being greater than export of energy, the net energy consumed has to be billed as per the tariff order for sale of power. However, in the case of export being greater than import of energy, the net energy generated may be treated as power credit and carried over to the next billing cycle
  • Excess energy generation if available at the end of the year may be paid by TANGEDCO at 75% of the solar tariff fixed by the commission

Information about the procedure for LT connectivity for solar generation is also provided in this document along with the standards of meter, harmonics standard and inverter standard provided in the Annexure – A, B and C.

For detailed information the original document with this procedure can be downloaded here. It must be noted that the last date for submission of comments/suggestions to TANGEDCO related to this document was closed on 15th August, 2013 and the final procedure document is awaited. source efficient carbon


 

 

 

TIME OF USE

  • This is a feature present in some of the net meters, that gives you benefits of conserving electricity during peak hours.
  • It calculates the price along the incentive calculations and gives you the final price

This feature can be added in net meters that are going to be installed in India.   http://www.premierpower.com/solar_energy_commercial/net_metering.php    


 

TWO METERING CONCEPT  

 

This is a very unique and simple concept used in Oregon,USA. This concept ccontains of two net meters  

  1. PHOTOVOLTAIC METER
  2. NET METER

 

The photovoltaic meter and the the net meter both have different purposes.

  • The photovoltaic meter keeps track of how much energy is produced by your solar panels.
  • The net meter keeps track of energy flowing to and from your utility provider.

Here are some examples of how this works:

Let's say your solar panels provide 200 kwh of energy. Here are three scenarios showing how energy is measured at the net meter:

  • If you consumed 200 kwh in a given month, the photovoltaic meter would read 200 kwh and the net meter would read 0 kwh.
  • If you consumed 100 kwh in a given month, the photovoltaic meter would read 200 kwh and the net meter would read -100 kwh (credit).
  • If you consumed 500 kwh in a given month, the photovoltaic meter would read 200 kwh and the net meter would read 300 kwh usage from GRID.   This concept also can be tried in India.

 SOLAR POWER WILL BECOME CHEAPER THAN GRID POWER

 

  • The burden of the utility becomes a lot less, hence it reduces the pressure from the grid
  • But the profits are substantially reduced, hence utility electricity prices go up.
  • Solar power prices will become cheaper than the grid.

  • This is a complete 'self-reinforcing  cycle', It will help the power crisis
  • Net meters can give complete report of power generation to the grid database , so that power can be driven efficiently
  • Transmission losses can be drastically reduced.

 Approach For Producing And Managing Electricity

ABSTRACT An approach for producing and managing electricity includes producing electricity off premise while providing offsetting of power consumed on premise. As used herein, the term “off premise” refers to a location other than the location where electricity is being consumed and the term “on premise” refers to the location where the electricity is being consumed. The approach is applicable to any method or technology for generating electricity. Participants or customers have an ownership interest in the power generating facility. The offsetting of power may be accomplished using a wide variety of techniques, for example, energy production data may be reported to the premise where electricity is consumed and/or to an electric utility company to allow for customer billing credits, adjustments and/or direct or in-direct utility meter off-sets (net metering). Thus, each participant produces the power they consume with electricity production equipment in which they have an ownership interest.

Solar Power Production and Metering

 

ABSTRACT Systems and methods for positioning photovoltaic panels above agricultural land are disclosed. The photovoltaic panels can be suspended over agricultural land and supported by vertical holders, which are generally arranged in a two-dimensional grid. Sufficient clearance exists between the base surface and the photovoltaic panels for the operators and the agricultural machinery. The position of the photovoltaic panels can be adjusted using panel orientation systems. A decision about the photovoltaic panel angle with respect to the incoming sunlight can be based on the insolation/shade needs of the agricultural plants beneath the system and also on the need to generate electrical energy by insolating the panels. Furthermore, the systems and methods can be used for a net metering of energy. An energy ratepayer who is also a sole or fractional owner of the renewable energy production capacity can subtract the energy production from the energy consumption, thus resulting in the net metering of energy.

 ADVANTAGES OF NET METERING

  • It is used reduce demand during long simmer days.
  • Energy credits is a attractive incentive to bring down the load during peak demand
  • It allows energy consumers to reduce thier power bills saving not only money and energy for the environment.
  • Net meter offer additional fratures of storing power in case of large generating systems

https://www.apeasternpower.com/framework/skins/EPDCL_SKIN/Pdfs/Solar Power Generation Net Metering.pdf


 

 NET METER VS GROSS METER

  • A net meter calculates the net difference of the total power consumed to the total power generated.
  • Hence such a net meter should be a interval based one and should be read in periods. So that energy producer can confidently export energy to the grid.  

Net meter 2

  •  A Gross meter measure the consumption and generation seperately .
  • So the Gross meter measures the entire output of the system seperately.
  • Gross meter can help not only calculating the gross meter calculations but also net meter calculations.

    kanagagnana -

    Please note all the old disk type meters are Bidirectional! It is made to work only in one direction to prevent the meter creeping backwards at no load or low loads. So all what we need is to have the normal meter with the non reversing block been removed.
    There is no need to go for costly two meter system. I am sure this will facilitate the introduction of Net Metering at much lower costs.
    These points must be made clear to the public and requirement of two meters must be abolished please. Hope this consultancy firm will take this matter with the necessary Authorities.
    Single Electronic meters will do the job better. But we need not wait for them or different set of bidirectional meters. Like
