India launches 2 GW solar, 4 GWh storage tender

SECI is tendering for 2 GW of grid-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 anywhere in India.

The developer must install ESS capacity of at least 500 kW/2 MWh for each 1 MW of solar project capacity contracted. The ESS component may either be owned by the developer or tied-up separately with a third-party for the supply of power.

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

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

The solar power developer is mandated to deliver 2 MWh of energy per megawatt of rated project capacity, in alternating-current terms, during peak grid demand 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.
