NTPC Green Energy Limited (NGEL), the renewables arm of India’s state-owned NTPC, has launched an EPC tender for a 3,200 MWh battery energy storage system co-located with the Fatehgarh solar plant in Rajasthan. The Fatehgarh procurement is one of several large storage tenders NGEL has floated this quarter as India ramps to gigawatt-scale BESS deployment.
Two 300 MW Blocks Plus A 200 MW Block
The tender is structured as two blocks of 300 MW / 1,200 MWh BESS plus one block of 200 MW / 800 MWh BESS. Bidders compete through a single-stage, two-envelope domestic competitive bidding process, with techno-commercial and price bids followed by a reverse auction. Bid submissions close on June 25, 2026.
25-Year Design Life And Tight Performance Specs
NGEL is requiring a 25-year design life and batteries capable of at least 10,000 charge-discharge cycles, with a monthly round-trip efficiency of 80% including auxiliary load and minimum annual availability of 98%. Winning bidders will deliver 15 years of operations and maintenance.
Part Of A 17.5 GWh Storage Push
The Fatehgarh tender sits inside a broader NGEL programme that has floated more than 17 GWh of BESS capacity in 2026, including EPC packages tied to solar plants in Gujarat and Rajasthan. It mirrors gigawatt-scale storage moves in Australia, where TagEnergy’s 1 GW / 4,000 MWh Morwell BESS just secured planning approval, and in Europe, where Sungrow and partners are building the Nova Zagora project in Bulgaria.
What It Signals
The tender effectively sets a new reference for utility-scale BESS pricing and durability requirements in India, with implications for global suppliers eyeing the country’s clean-energy boom. Domestic players such as Reliance, Tata Power and JSW Energy face fresh pressure to chase comparable BESS contracts to stay competitive.
