Punjab State Power Corporation Limited has released a Notice Inviting Tender (NIT) for the development of a 500 MW/1000 MWh standalone Battery Energy Storage System (BESS) in Punjab. The project aims to enhance grid stability and improve electricity reliability across the state by enabling large-scale energy storage.
The tender will follow a Tariff-Based Global Competitive Bidding (GBB) framework and will be managed by the Office of the Chief Engineer/NRSE & Thermal Designs, Patiala. The initiative forms part of Punjab’s broader strategy to strengthen power infrastructure and facilitate the integration of renewable energy into the grid. Battery storage systems are expected to store surplus electricity and supply power during peak demand, helping manage fluctuations in generation.
Tender documents are available on the Bharat Electronic Tender portal. Companies wishing to participate in the pre-bid meeting must register by March 24, 2026, which is also the deadline for submitting any queries regarding the tender. PSPCL has mandated that all bids be submitted through the official online e-bidding portal, while certain financial instruments, including the Earnest Money Deposit (EMD), will require both online and offline submission.
The tender schedule is as follows: documents were made available from March 10, 2026, 3:00 PM; bid submission closes on April 10, 2026, 3:00 PM; technical bids will be opened on April 16, 2026, 11:00 AM; and financial bids are set to be opened on May 11, 2026, 11:00 AM. Submitted bids will remain valid until April 10, 2027.
Financial requirements for bidders include an Earnest Money Deposit of ₹4,71,000 per MW and a Performance Bank Guarantee of ₹11,77,500 per MW. Additional costs include a bid processing fee of ₹3,00,000 plus GST and a Request for Selection (RFS) document fee of ₹50,000 plus GST. The EMD must be submitted as a Bank Guarantee, Payment on Invocation, or Insurance Surety Bond from a nationalized bank or recognized financial institution such as Power Finance Corporation (PFC) or Rural Electrification Corporation (REC).
This BESS project is expected to play a key role in enabling renewable energy integration and enhancing the resilience of Punjab’s electricity grid.
