India: SECI launches 1 GW/2 GWh battery storage tender, Serentica seeks partners for 800 MWh standalone battery projects

SECI has started accepting proposals to set up 1 GW/2 GWh of ISTS-connected standalone BESS. It will enter into a battery energy storage purchase agreement with the successful bidders.

Developers selected by SECI will set up the BESS on a build-own-operate basis at specified locations.

A single developer can bid for a minimum cumulative project capacity of 50 MW/100 MWh and maximum of 1,000 MW/2,000 MWh. Project capacity must be quoted in integral values.

In a separate announcement, Indian renewable energy solutions provider Serentica Renewables has invited expressions of interest (EoI) to set up interstate transmission system-connected battery energy storage systems (BESS). The projects should supply 800 MWh of battery storage capacity to Serentica’s round-the-clock green energy projects.

The projects comprise 200 MW/400 MWh of 2-hour storage and 100 MW/400 MWh of 4-hour storage, requiring at least 51% ownership by the BESS provider. Serentica will procure the BESS capacity on an annual basis under a 12-year service agreement, starting June 2026 onwards.

The last day to submit the bids is July 30, 2024.

Serentica is currently executing 4 GW of projects and will deliver 2 GW per year of round-the-clock green energy to large industrial customers in India.
