SECI Issues 125 MW/500 MWh 4-Hour BESS Tender in Odisha

SECI has recently issued a tender to set up a 125 MW/500 MWh Battery Energy Storage System (BESS) in Odisha and to make an energy storage facility available to GRIDCO for charging and discharging of the BESS on an “on-demand” basis. It has sought online bids for the tender till January 21, 2025, and offline bids till January 23, 2025. 

Under the scope of work of the tender, the Battery Energy Storage System Developer (BESSD) is required to set up, operate, and maintain a Battery Energy Storage System (BESS), and to make the energy storage facility available to GRIDCO for charging and discharging on an “on-demand” basis.

Through this tender, SECI aims to select six BESS projects for a 125 MW project with four-hour storage capacity. With a total capacity of 125 MW/500 MWh (i.e., five projects of 20 MW/80 MWh each and one project of 25 MW/100 MWh). The selection will be carried out through e-bidding, followed by a separate e-reverse auction process for each project cluster.
