Power Grid Corporation of India Limited (POWERGRID) has invited online bids for a major battery energy storage project in West Bengal, marking another important step toward strengthening the state’s renewable energy and grid infrastructure. The tender, issued under Reference Number CC/T/W-BESS/DOM/A00/26/07589, seeks contractors for the design, supply, erection, testing, and commissioning of a 200 MW/800 MWh Battery Energy Storage System (BESS) at DPL West Bengal.
The project, known as “Package WB BESS 01,” forms part of a much larger initiative aimed at developing 750 MW/3000 MWh of standalone battery energy storage capacity across various locations in West Bengal. The broader program is being implemented through a Tariff-Based Competitive Bidding (TBCB) process and is expected to support the integration of renewable energy while improving grid reliability and energy management.
