Developers would be able to bid for a total capacity of between 200MW and 500MW with individual projects of at least 50MW, according to rules drafted by the ministry of new and renewable energy (MNRE).
Capacity would be allocated based on the lowest tariff offered until the full 2.5GW is assigned – a so-called reverse auction.
Bidders would be competing to secure power purchase agreements (PPAs) with the Solar Energy Corporation (SECI) lasting 25 years from the operational start date of a project.
SECI will issue a request for selection document for bidding under the scheme by 9 June.
Earlier this month the MNRE pledged to encourage development of wind-solar hybrid projects and vowed to publish a scheme underpinning this policy.
Last month Hero Future Energies commissioned the country’s first large-scale wind-solar hybrid project.
