NTPC Green Energy Ltd (NGEL) has invited bids for the engineering, procurement, and construction (EPC) of a grid-connected 130 MW/520 MWh battery energy storage system (BESS) on a turnkey basis. The project is split into two blocks: Ramagundam (100 MW/400 MWh) and Sipat (30 MW/120 MWh).
The scope of work includes the design, engineering, supply, construction, erection, testing, and commissioning of the grid-connected BESS.
According to the tender document, “The BESS capacity to be considered is the rated AC discharge capacity at the point of injection/metering. The BESS should be integrated at the 33 kV pooling substation of the solar plant. Each BESS unit should be housed in a standardized container with a minimum DC capacity of 5 MWh.”
The BESS, including batteries, must be designed for a lifespan of 15 years, assuming daily single-cycle operation, starting from the successful completion of the trial run.
