NTPC Invites Bids For 2,420 MWh BESS Implementation Across Seven Thermal Power Stations

NTPC Limited, a leading Government of India enterprise, has issued an Invitation for Bids (IFB) for a major infrastructure initiative aimed at strengthening the nation’s power grid. The tender is for the Engineering, Procurement, and Construction (EPC) package for Battery Energy Storage System (BESS) implementation at NTPC thermal power stations, designated as Lot-2. The bidding is being conducted through a Domestic Competitive Bidding process on a Single Stage Two Envelope Basis, meaning technical and price bids will be evaluated separately.

The project under Lot-2 encompasses seven thermal power stations across India, with a total aggregated BESS capacity of 2,420 MWh. Barauni Thermal Power Station has the largest capacity at 1,000 MWh, followed by Gadarwara Super Thermal Power Station at 320 MWh, NTECL-Vallur Thermal Power Station at 300 MWh, Khargone Super Thermal Power Station at 250 MWh, National Capital Power Station Dadri-II and Tanda Super Thermal Power Station-II at 200 MWh each, and Bongaigaon Thermal Power Station at 150 MWh. This project reflects NTPC’s focus on deploying advanced energy storage solutions to enhance grid stability, efficiency, and reliability.

Eligible bidders must meet strict qualifying requirements, particularly regarding financial capacity. A key criterion is the Average Annual Turnover (AAT), which must meet or exceed the specified threshold. The AAT calculation is based on net worth, reserves, and share premium accounts, excluding reserves from asset revaluation, write-back of depreciation, or amalgamation. Debit balances in the Profit and Loss account and unadjusted miscellaneous expenses are subtracted from total reserves, and other income is not considered. Bidders can quote for all projects for which their AAT is sufficient, but final contract awards will depend on meeting the aggregate financial requirement and being the Lowest Evaluated Bidder (L1).

Participation in the tender requires submission of an Earnest Money Deposit (EMD), which serves as a guarantee of bidder seriousness and ensures against last-minute withdrawal. Successful bidders will also be required to provide a Performance Bank Guarantee (PBG), typically ranging from 3% to 10% of the contract value, to assure NTPC of satisfactory fulfillment of contractual obligations, including execution and warranty periods.

An important date, such as the bid submission end date, is 30^th December 2025. Interested parties are advised to adhere strictly to these timelines and financial requirements to ensure their bids are valid and considered for evaluation. This initiative underscores NTPC’s ongoing commitment to integrating cutting-edge storage solutions into India’s power infrastructure, enhancing grid resilience, and supporting the country’s renewable energy objectives.
