India’s Ministry of New and Renewable Energy has launched a consultation in advance of a proposed 1 GW wind power project auction.

The move is aimed at helping states meet non-solar renewable power purchase requirements and boosting wind power trading between states.

The auction would be the nation’s first and would cover multiple states, with a minimum project size of 25 MW and aspiring project developers able to choose their own wind farm site.

Solar Energy Corporation of India (SECI) is to administer the auction, which will set tariffs based on those already established by the states’ power market regulators. The projects will receive 25-year power purchase agreements (PPAs).

Selected projects are to be completed within 15 months.

India aims to install 60 GW of wind power capacity by 2022. Its current installed capacity is 27 GW, boosted by a record 3.46 GW installed in 2015.

However, analysts have noted that many wind power projects struggle to find buyers for their power as utilities tend to prefer cheaper coal-fired power.
