Solar Energy Corp. of India (SECI) has invited bids for setting up 2 GW of solar PV projects with energy storage systems (ESS) in India. The projects must be developed on a build-own-operate basis. These can be located anywhere in India and must be connected to the inter-state transmission system.
SECI will enter into a Power Purchase Agreement (PPA) with the successful bidders for a period of 25 years. The power obtained by SECI from the projects is intended for sale to the various purchasing entities in India
As part of the project, an ESS of at least 0.5 MW/2 MWh capacity for 1 MW solar project capacity must be installed. ESS charged from a source other than solar energy does not qualify as solar energy. ESS can be owned by the developer or separately connected to a third party for power supply. The ESS technology may be changed by the developer at any time during the term of the PPA.
A developer must submit one bid for a minimum of 50 MW of contracted capacity and a maximum of 1,000 MW, in multiples of 10 MW.
“Bidders who have already commissioned solar PV projects or are in the process of constructing such projects and have uncommitted capacity can also participate. In such case, they will get the benefit of a longer period of PPA, proportionate to the length of time between the actual date of commencement of power supply and the planned date of commencement of supply,” the tender document said.
