The Solar Energy Corporation of India (SECI) has issued a tender for developing standalone battery energy storage systems (BESS) with a total capacity of 500 MW/1 GWh in India. SECI has issued a request for selection (RFS) document for developing the two BESS projects at a single location in the vicinity of Fatehgarh-III substations grid-substation of the inter-state transmission system (ISTS) network in Rajasthan. The pilot projects will be developed on a build, own, and operate basis.
Furthermore, a total capacity of 500 MW/1 GWh will be installed at a single site, with two 500 MWh (250 MWh x 2) projects each. As per the guidelines, a bidder can submit a single proposal for either 250 MW/500 MWh or 500 MW/1 GWh of committed capacity. The bid submission deadline is June 10, 2022. The winning bidder will be required to sign the battery energy storage purchase agreements.
The composition of capacity offtake is a distinctive element of this tender. Out of the total capacity being installed under the tender, 60 per cent of the capacity will be acquired by SECI on behalf of the buying entities, while the developers would offtake 40 per cent of the capacity through third-party or market sale. As a result, the government provides substantial support for market development in the energy storage domain through this procurement.
This tender is the first phase of a procurement drive for 4,000 MWh of BESS capacity.
