Guidelines Issued for Setting up of Wind Power Projects
Dec 03, 2016

Ministry of New & Renewable Energy (MNRE) has sanctioned a Scheme for Setting up of 1000 Mw Inter State Transmission System (ISTS) connected Wind Power Projects. The Scheme provides for formulation of Guidelines by MNRE for implementation of the Scheme. 

Salient Features of the Guidelines

  • Scheme to be implemented by Solar Energy Corporation of India (SECI).
  • Wind projects will be selected through open and transparent competitive bidding process followed by e-reverse auction.
  • Eligible project capacity will be minimum 50 Mw and maximum 250 Mw per bidder. 
  • Trading Company, selected by SECI, will sign Power Purchase Agreement (PPA)   with selected bidder and back-to-back Power Sale Agreement (PSA) with buying entities at a pooled price of the total bids selected. 
  • The duration of PPA and PSA will be 25 years from commercial operation date of the project.
  • The transmission of power up to the point of interconnection where the metering is done for energy accounting shall be the responsibility of the bidder. Use of State transmission system to bring wind power at ISTS point also allowed.
  • Part commissioning allowed subject to commissioning of atleast 50 Mw or 50% of the allocated Project Capacity, whichever is higher.
  • Project to be completed within 18 months from issue of Letter of Award. Maximum period of 27 months allowed for completion of project with penalties.
  • Minimum declared Capacity Utilization Factor to be 20%. Provision of compensation in case of shortfall in minimum generation.
  • Wind projects to submit monthly performance data through Online.

Wind Energy Programme in India

  • The Wind power programme in India was initiated towards the end of the Sixth Plan, in 1983-84. 
  • A market-oriented strategy was adopted from inception, which has led to the successful commercial development of the technology. 

National Programme: The broad based National programme includes wind resource assessment activities; research and development support; implementation of demonstration projects to create awareness and opening up of new sites; involvement of utilities and industry; development of infrastructure capability and capacity for manufacture, installation, operation and maintenance of wind electric generators; and policy support. 

The programme aims at catalyzing commercialisation of wind power generation in the country. The Wind Resources Assessment Programme is being implemented through the State Nodal Agencies, Field Research Unit of Indian Institute of Tropical Meteorology (IITM-FRU) and Center for Wind Energy Technology (C-WET).

Weather Influence on Winds


Wind in India are influenced by the strong south-west summer monsoon, which starts in May-June, when cool, humid air moves towards the land and the weaker north-east winter monsoon, which starts in October, when cool, dry air moves towards the ocean. During the period march to August, the winds are uniformly strong over the whole Indian Peninsula, except the eastern peninsular coast. Wind speeds during the period November to march are relatively weak, though higher winds are available during a part of the period on the Tamil Nadu coastline. 

A notable feature of the Indian programme has been the interest among private investors/developers in setting up of commercial wind power projects. The wind power generation capacity in India is 49,130 Mw as per the official estimates in the Indian Wind Atlas (2010) by the Centre for Wind Energy Technology (C-WET). The potential is calculated with respect to 2 per cent land availability at windy locations and pertains to a 50 meter hub height level of the wind turbines. Presently large wind turbines with higher hub height in the range of 80-100 meter with large rotor diameters up to 120 meter are available in the Indian market. Conceding technological advancement and higher wind speeds at higher hub heights, the potential of 49,130 Mw at 50 meter level if extrapolated at 80 meter standard hub height, the projected wind potential using the same land availability will be in the order of 1,02,788 Mw (not officially declared owing to lack of validation). As on March 31, 2015 a total of about 23439.26 Mw of commercial projects have been established until.
