Sunsure Energy on Thursday announced it has signed a Battery Energy Discharge Purchase Agreement (BEDPA) with NTPC Vidyut Vyapar Nigam Ltd. (NVVN), a wholly owned subsidiary of NTPC Ltd., to supply 125 MW/500 MWh of peak power from a Battery Energy Storage System (BESS) to Uttar Pradesh Power Corporation Ltd. (UPPCL).
The 15-year agreement marks Sunsure Energy’s first long-term power supply deal through BESS. The project will be built under the build–own–operate (BOO) model at the Garautha substation (400/220 kV) in Jhansi, Uttar Pradesh.
Under the pact, Sunsure will deliver four hours of on-demand power between 6 p.m. and 10 a.m., giving UPPCL flexibility to source renewable energy during evening and morning peak demand hours at competitive long-term tariffs.
In a significant first for India’s energy storage ecosystem, the agreement introduces a tariff structure based on discharged energy (₹/kWh), rather than fixed monthly rates—ushering in a new commercial model for BESS projects in the country.
“This agreement is a historic step in India’s renewable transition. We’ve moved from pure-solar offerings to hybrid systems with BESS, enabling C&I customers to access renewable energy even during peak hours, while displacing fossil power from the grid,” said Shashank Sharma, Founder, Chairman and CEO of Sunsure Energy. “On the utility side, our journey has evolved from winning SECI’s solar bids to SJVN’s advanced hybrid tenders, and now NVVN’s first-of-its-kind BESS deployment.”
The agreement underlines NVVN and Sunsure’s role in accelerating India’s clean energy goals, while giving UPPCL greater resilience in managing peak-hour power demand.
