SECI Awards 1 GW/2 GWh BESS Project to JSW And Reliance

SECI has announced that JSW Neo Energy and Reliance Power are the successful bidders for 1,000 MW/2,000 MWh standalone battery energy storage systems (BESS), under tariff-based global competitive bidding.

Both companies were awarded an equal capacity of 500 MW/1,000 MWh. JSW Neo Energy quoted a tariff of Rs. 381,000/MW per month, and Reliance Power quoted a tariff of Rs. 381,999/MW per month. The discovered tariff of INR 3.81 lacs/MW/month is a steep drop from SECI’s first standalone BESS tender that had attracted bids at INR10.83 lac/MW/month. However, it is just above GUVNL’s recent Phase 3 tender that attracted bids at Rs 3.72 lacs/MW/month. GUVNL’s Phase 2 tender had attracted bids at Rs 4.49 lacs/MW/month.

These developers will now undertake the task of building Battery Energy Storage System Developers (BESSD). They are required to set up a Battery Energy Storage System (BESS) with the primary objective of making the energy storage facility available to the Buying Entities for charging/discharging the BESS on an “on-demand” basis. The tender also marks Reliance’s formal entry into the solar market.
