Wind Power Programme


The broad based Wind Power Programme of the Ministry aims to catalyze commercialization of grid interactive wind power.  

WIND RESOURCE ASSESSMENT  

Under National Wind Resource Assessment programme, Ministry through National Institute of Wind Energy, Chennai (erstwhile Centre for Wind Energy Technology (C-WET)) and State Nodal Agencies had installed and monitored 794 dedicated Wind Monitoring Stations (WMS) of height ranging from 20 m to 120 m (20m, 25m, 50m, 80m, 100m & 120m) throughout the country as on 31.12.2014. Initially the wind monitoring was carried out only in known windy areas. Now it is extended to new/ uncovered areas which are not explored in earlier projects to complete the Indian Wind resource mapping. Further hundreds of private winds monitoring stations are also operational in the country.  Based on the analysis on the data collected from these 700 plus WMS, it is found that 237 stations have economically preferable wind power
potential greater than 200 W/m2.                                                                       A wind power project in Gujarat  

POTENTIAL  

The Potential for wind power generation for grid interaction has been estimated at about 1,02,788 MW taking sites having wind power density greater than 200 W/sq. m at 80 m hub-height with 2% land availability in potential areas for setting up wind farms @ 9 MW/sq. km.

TECHNOLOGY  

Two types of wind turbines namely stall regulated and pitch regulated are being deployed in the country and abroad for grid-interactive power. The stall regulated wind turbines have fixed rotor blades whereas pitch regulated wind turbines have adjustable rotor blades that change the angle of attach depending upon wind speed. Both technologies have their own advantages and disadvantages. Wind turbines are also available with lattice, steel tubular and concrete tubular towers.  

DEMONSTRATION PROGRAMME  

An aggregate demonstration wind power capacity of 71 MW has been established at 33 locations in 9 states viz., Andhra Pradesh, Gujarat, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu and West Bengal. Demonstration projects are implemented through the State Governments, State Nodal Agencies or State Electricity Boards. Demonstration projects will be taken up only in those states where commercial wind power projects have not yet been initiated/taken off.  

DEPLOYMENT  

A total capacity of 22,465 MW has been established up to December, 2014, mainly in Tamil Nadu, Gujarat, Maharashtra, Andhra Pradesh, Karnataka and Rajasthan. Wind electric generators of unit sizes between 225 kW and 2.1 MW have been deployed across the country. India now ranks 5th in the world after China, USA, Germany and Spain in grid connected wind power installations. A cumulative total of over 179 billions units of electricity have been fed to the State Electricity Grids up to March, 2014.  

MANUFACTURING BASE OF WIND ELECTRIC GENERATORS  

Wind Electric Generators are being manufactured in the country by a dozen manufacturers, through (i) joint ventures under licensed production (ii) subsidiaries of foreign companies, under licensed production and (iii) Indian companies with their own technology. An indigenization level up to 70% has been achieved in machines of unit sizes up to 500 kW. The import content is somewhat higher in higher capacity machines. The current annual production capacity of domestic wind turbines is about 9500 MW.  

GUIDELINES FOR SETTING UP PROJECTS  

The Ministry has been issuing guidelines for wind power development since July 1995 in order to bring about balanced growth of the sector. These guidelines relate to preparation of detailed project reports, micro-siting, selection of wind turbine equipment, operation & maintenance, performance evaluation, etc. A list of manufacturers of certified wind turbine machines is issued by CIWE on quarterly basis.

GUIDELINES FOR INSTALLATION OF PROTOTYPE WIND TURBINES

  

PROMOTIONAL POLICIES  

A package of fiscal and financial incentives is available which includes concessions such as 80% accelerated depreciation, concessional custom duty on specified items, excise duty exemption, sales tax exemption, income tax exemption for 10 years, etc. In addition, State Electricity Regulatory Commissions (SERCs) are determining preferential tariffs. Indian Renewable Energy Development Agency (IREDA) provides loan for setting up wind power projects.  

In 2009, the Ministry introduced a Generation Based Incentive (GBI) Scheme for wind power projects wherein wind power projects not availing the Accelerated Depreciation (AD) benefit are eligible for GBI incentive at the rate if Rs. 0.50 per unit of power fed to the grid subject to the ceiling of Rs. 1 Crore per MW.

National Institute of Wind Energy (NIWE)  

The National Institute of Wind Energy (NIWE), Chennai was established in Tamil Nadu in 1998 as an autonomous institution under the administrative control of the Ministry of New and Renewable Energy. CIWE main activities include resource assessment and testing & certification.
