The Damodar Valley Corporation (DVC) has issued a tender for the development of a 250 MW/500 MWh battery energy storage system (BESS) in Maithon, Jharkhand. The project is a part of its Phase I plan to install a total of 500 MW/1,000 MWh BESS capacity across Jharkhand and West Bengal. According to the tender guidelines, the scope of the work includes design, engineering, installation, testing, and commissioning. The project must be developed with a 12-year design life and include operation and maintenance services, civil works, and a minimum 12-year warranty covering the BESS battery, battery management system, energy management system, and power conditioning system (PCS). The deadline for bid submission is May 21, 2025.
The BESS must integrate a complete control, protection, and communication system, alongside auxiliary power and monitoring capabilities. Additionally, it must also support power evacuation of 250 MW for two hours daily to the grid during the peak hours, charged up to 85 per cent from floating solar and hydroelectric sources. At least 70 per cent of the system’s capacity must be dispatched over the battery’s lifetime. Successful bidders are required to supply 2 per cent of mandatory spares, detailed documentation of design and expected performance, and conduct factory acceptance and type testing. Site-specific data must be collected to plan installation, with all necessary tools, initial spares, and project maintenance equipment supplied.
