SECI launches tender for 2 GW solar with 1 GW/4 GWh storage

Share

Solar Energy Corp. of India has issued a tender for selection of developers to set up 2 GW of interstate transmission system (ISTS) connected solar projects with 1 GW/4 GWh of energy storage systems (ESS). The projects, to be developed on a build-own-operate basis, can be set up by the developers on the locations chosen by them.

The developer must install ESS capacity of at least 0.5 MW/2 MWh for each 1 MW project capacity contracted. The ESS component may either be owned by the developer or tied-up separately with a third-party for supply of power.

SECI will sign 25-year power purchase agreements (PPAs) with selected developers.

A developer must bid for a minimum cumulative capacity of 50 MW and maximum 1 GW, in multiples of 10 MW.

The solar power developer is mandated to deliver 2 MWh of energy per MW rated project capacity in AC terms, during peak hours as per the schedule given by the buying entity (i.e., for each 100 MW of project capacity, the developer will supply up to 200 MWh of energy during peak hours), on a daily basis.
