Sunsure Energy, renewable energy solutions provider for businesses and utilities transitioning to green power, is proud to announce the signing of a Battery Energy Discharge Purchase Agreement (BEDPA) with NTPC Vidyut Vyapar Nigam Ltd (NVVN), a wholly owned subsidiary of NTPC Ltd, securing a capacity of 125MW/500MWh, a company statement said.

Backed by a 15-year agreement, Sunsure will supply power to NVVN with Uttar Pradesh Power Corporation Ltd (UPPCL) being the end procurer.

Under the agreement, Sunsure will set up a standalone Battery Energy Storage System (BESS) under the build–own–operate model at Garautha substation (400/220 kV) in Jhansi, Uttar Pradesh.

The project marks Sunsure's first long-term power supply agreement through BESS.

Through the agreement, Sunsure will deliver 4 hours of on-demand power between 6 pm and 10 am, giving UPPCL the flexibility to source clean energy at peak demand hours (evening or morning) at competitive and long-term tariffs.

This brings a historic shift in India's energy storage ecosystem as it is a first-of-its-kind BESS agreement where instead of fixed monthly rates, billing is based on fixed tariff (Rs/kWh) of discharged energy.

Shashank Sharma, Founder, Chairman & CEO of Sunsure Energy said in the statement, "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 more fossil energy from their energy mix. On the utility side, our evolution is clear -- from winning SECI's pure solar bids to SJVN's advanced hybrid tenders, and now, NVVN's first-of-its-kind BESS deployment in the country."
