Bihar State Power Generation Company Invites Bids for 125 MW/500 MWh Battery Storage Project

Bihar State Power Generation Company Limited (BSPGCL) has issued a tender for a 125 MW/500 MWh standalone battery energy storage system under the Build, Own, Operate, and Transfer (BOOT) model. The project will be supported by Viability Gap Funding (VGF) and will help Bihar enhance its grid stability and renewable energy integration.

Key Details:

• Bid Submission Deadline: March 23, 2025
• Bid Opening Date: March 24, 2025

• Viability Gap Funding: Rs0.27 crore/MWh or 30% of capital cost, whichever is lower
• Grid Connection Voltage: Minimum 33 kV

Project Structure & Requirements:

• Charging & Discharging: The BESS will be charged by drawing power from the grid and discharged based on instructions from the State Load Dispatch Center (SLDC) in coordination with DISCOMs.
