The Solar Energy Corp. of India Ltd (SECI) has issued a tender for the development of 1.2 GW of interstate transmission system (ISTS)-connected solar power projects, integrated with 600 MW/3600 MWh of energy storage systems (ESS), on a build-own-operate (BOO) basis.

SECI will enter into a 25-year power purchase agreement (PPA) with successful bidders for the procurement of solar power from these projects. The procured power will be sold to various buying entities across India, with SECI acting as an intermediary nodal agency facilitating back-to-back transactions between solar developers and buyers.

A developer must bid for a minimum cumulative capacity of 50 MW and maximum 600 MW.

The solar developer must install ESS capacity of at least 0.5 MW/ 3 MWh for each 1 MW project capacity contracted under the PPA. The ESS component may either be owned by the solar developer or tied-up separately with a third-party.

“The projects shall be located at the locations chosen by the developer at its own discretion of and cost, risk and responsibility. A single project can be set up at multiple locations with different delivery points. The ESS component needs to be co-located with the project, however, in case of a project located at multiple locations, the ESS needs to be co-located with at least one of the components,” reads the tender document.
