The tender, launched by SJVN in June, mandated that projects be developed on a build, own, and operate basis. Developers with existing or under-construction untied capacity in renewable energy or storage projects were eligible to bid. The selected developers are also responsible for securing ISTS connectivity at their own expense, as per applicable regulations.

Furthermore, SJVN specified that wind turbine models listed in the Revised List of Models and Manufacturers and solar modules registered in the Approved List of Models and Manufacturers issued by the Ministry of New and Renewable Energy must be utilised in the projects.

Projects are required to maintain an annual capacity utilisation factor (CUF) of at least 40%. Developers must ensure generation that aligns with an annual CUF within +10% and -15% of the declared value throughout the 25-year power purchase agreement duration.
