Sunsure Energy has signed a Battery Energy Discharge Purchase Agreement (BEDPA) with NTPC Vidyut Vyapar Nigam Ltd (NVVN) for the supply of 500 MWh peak-time clean power to Uttar Pradesh Power Corporation Ltd (UPPCL), marking a milestone in India’s evolving energy storage landscape.

The agreement covers a capacity of 125 MW/500 MWh and is structured as a 15-year build–own–operate deal, with Sunsure Energy establishing a standalone Battery Energy Storage System (BESS) at the 400/220 kV Garautha substation in Jhansi, Uttar Pradesh.

As part of the arrangement, Sunsure will deliver four hours of dispatchable electricity daily between 6 pm and 10 am. This will provide UPPCL the flexibility to meet peak-hour electricity demand using clean energy, ensuring reliability at competitive, long-term tariffs.

What sets this agreement apart is its innovative billing model: instead of fixed monthly charges, it is based on a fixed tariff per kilowatt-hour (Rs/kWh) of discharged energy, making it the first-of-its-kind BESS contract of this nature in the country.

“This is a significant leap for us,” said Shashank Sharma, Founder, Chairman and CEO of Sunsure Energy. “We’ve expanded beyond pure-solar to hybrid systems with BESS, empowering commercial and industrial consumers to use renewable power even during peak times, thus reducing their dependence on fossil fuels. For utilities, our journey—from SECI’s solar auctions to SJVN’s hybrid tenders and now NVVN’s pioneering BESS deal—highlights our growth and vision.”
