India Wind Energy

Introduction[i]

Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

Technology[ii] [iii]

Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Wind turbines generally have three rotor blades, which rotate with wind flow and are coupled to a generator either directly or through a gear box. The rotor blades rotate around a horizontal hub connected to a generator, which is located inside the nacelle. The nacelle also houses other electrical components and the yaw mechanism, which turns the turbine so that it faces the wind. Sensors are used to monitor wind direction and the tower head is turned to line up with the wind. The power produced by the generator is controlled automatically as wind speeds vary. The rotor diameters vary from 30 metres (m) to about 90 m, whereas the towers on which the wind electric generators (WEGs) are mounted, range in height from 25 to 80 m.

Economics of Wind Energy



Government Wind Projects

National Wind Power Programme

The Wind Power Programme in India was initiated towards the end of the Sixth Plan, in 1983–84. The programme aims at survey and assessment of wind resources, setting up demonstration projects, and provision of incentives to make wind electricity competitive. As a result, wind electricity has emerged as an option for grid-quality power generation. The costs in respect of wind monitoring stations are shared between the Ministry of Non-Conventional Energy Sources (MNES) and the state nodal agencies in the ratio of 80:20 (90:10 for north-eastern states).

Wind Resource Assessment Programme

The Wind Resource Assessment Programme is being implemented by C-WET (Centre for Wind Energy Technology) in coordination with state nodal agencies. An annual mean wind power density greater than 200 W/m2 (watts per square meter) at 50-metre height has been recorded at 211 wind monitoring stations, covering 13 states and union territories, namely Andaman and Nicobar Islands, Andhra Pradesh, Gujarat, Karnataka, Kerala, Lakshadweep, Madhya Pradesh, Maharashtra, Orissa, Rajasthan, Tamil Nadu, Uttaranchal, and West Bengal.

Master plans

Master plans are available for 97 potential sites for wind power in Andhra Pradesh, Gujarat, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Orissa, Rajasthan, Tamil Nadu, and West Bengal. The master plans provide information on the availability of wind, land, grid availability, and accessibility to the site, which enables project promoters and state nodal agencies to undertake proper planning and implementation of the projects. The master plans have been provided to the state nodal agencies and are made available to project promoters, developers, and consultants through C-WET at a nominal cost.

Wind Energy for Water Pumping and Off-grid Power Generation Projects

Water-pumping windmill A water-pumping windmill pumps water from wells, ponds, and bore wells for drinking, minor irrigation, salt farming, fish farming, etc.

Aerogenerator

An aerogenerator is a small wind electric generator having a capacity of up to 30 kW.

Wind–solar hybrid systems

When an aerogenerator and an SPV system are interfaced, the power generation from these is mutually supplemented, and the resultant hybrid system offers a reliable and cost-effective electric supply in a decentralized mode.

Type Description
Water-pumping windmills Three water-pumping windmills of AV-55 type installed in and around Auroville have become the exclusive source of drinking water.
Aerogenerator
  • The West Bengal Renewable Energy Development Agency (WBREDA) has installed six aerogenerators of 3-kW capacity each in the existing SPV power plants at Sagar and Mousani islands.
  • A number of aerogenerators have been installed by the Maharashtra Energy Development Agency (MEDA), and are working satisfactorily. An aerogenerator of 3.2-kW capacity, installed at the Manashakti Research Centre, Lonawala, is supplying electricity to illuminate 22 streetlights.
Wind–solar hybrid systems
  • a 5-kW capacity wind–solar hybrid system installed on Vagator beach in Goa, which has become a destination point for tourists. The system illuminates 60 CFLs (compact fluorescent lamps) of 18 watts rating each.
  • A 15-kW wind–solar hybrid system has recently been installed at the famous pilgrimage site of Bhimashanker Deosthan, in Pune district, Maharashtra. This system provides electricity to meet the needs of the entire temple complex.

 Barriers

  • Initial cost for wind turbines is greater than that of conventional fossil fuel generators.
  • Noise produced by the rotor blades.
  • There is interference on television signals.It causes significant bird and other avian deaths.
  • Wind resources might not be available near cities and, even so, the space might be used for other purposes that can generate larger profits.
  • Wind cannot be stored (unless batteries are used)
  • Not all winds can be harnessed to meet the timing of electricity demands.

Wind energy research centres

Centre for Wind Energy Technology (C-WET)
Ministry of New and Renewable Energy (MNRE) has been planning and developing the basic infrastructure, institutions, and resources for carrying out research and development, large scale demonstration and diffusion of the non-conventional energy sources. As a step towards achieving these broad goals and to tackle the challenges in sustaining the development and accelerating the pace of utilization of wind energy in the country the Centre for Wind Energy Technology (C-WET) has been established by MNRE at Chennai as an autonomous R&D institution of Government of India. A Wind Turbine Test Station with technical and partial financial support by Danida, Government of Denmark, has been established at Kayathar, in Thoothukudi district, and Tamilnadu, as an integral part of the Centre.
