This was the first standalone BESS tender where charging the BESS falls under the scope of the developer. Also, the tariff is quoted in INR/kWh instead of the usual INR/MW/month.
Sunsure Energy emerged as the L1 bidder and secured 125 MW/500 MWh at a tariff of INR 6.64/kWh. Enrica Infra 3 (EnerGrid) won 125 MW/500 MWh at a tariff of INR 6.65/kWh.
The projects will be eligible for viability gap funding (VGF) support at INR 27 lakh/MWh or 30 percent of the capital cost of the project capacity awarded, whichever is lower.
The tender was floated in February 2025.
EnerGrid will be developing the project at Jhansi, Uttar Pradesh. This win adds to the company’s growing BESS portfolio as it adds to EnerGrid’s maiden win of 187.5 MW/750 MWh at SJVN’s auction at the same location. “This further solidifies our position as a fast-emerging player in India's rapidly evolving energy storage landscape,” stated the company.
“At EnerGrid, we are committed to accelerating India’s energy transition through targeted investments in transmission infrastructure and battery energy storage systems (BESS). Supported by our co-sponsors – IndiGrid, British International Investment, and Norfund – we are enabling next-gen infrastructure for a resilient, flexible, and sustainable energy ecosystem,” stated the company.
Commenting on the win, Shashank Sharma, Founder, CEO and Chairman, Sunsure Energy said, “I’m proud to share that Sunsure Energy has emerged as the winner in NVVN’s landmark standalone BESS tender – a first-of-its-kind initiative by NTPC Vidyut Vyapar Nigam Ltd. (a wholly-owned subsidiary of NTPC). With this win, Sunsure will invest an additional INR 1,000 crore in clean infrastructure in Uttar Pradesh, further advancing India’s goal of achieving 500 GW of renewable capacity by 2030.”He shared that the BESS plant will be connected to the 220 kV UPPTCL Substation at Garoutha, Jhansi, Uttar Pradesh. The plant is expected to be commissioned in Q4 FY27 and will involve investment of about INR 1,000 crore. “The investment in BESS would be about 500 crore. We will also be setting up solar capacity in UP to support the charging requirements of the BESS system. This would be an additional INR 500 crore,” stated Sharma.
He added that this win is going to further boost Sunsure’s ability to supply Round-The-Clock renewable energy. “Sunsure is able to set a benchmark for BESS power tariff in UP through our unique development capability and extensive presence in the state,” asserted Sharma.
