Sunsure Energy, a renewable energy solutions provider in India, has secured a battery energy discharge purchase agreement (BEDPA) with NTPC Vidyut Vyapar Nigam Ltd (NVVN), a wholly owned subsidiary of NTPC Ltd. Under the agreement, Sunsure will supply power to NVVN from a 125 MW/500 MWh standalone battery energy storage system (BESS) for a period of 15 years, with Uttar Pradesh Power Corp. Ltd (UPPCL) as the end procurer.
To supply the power, Sunsure will develop the BESS under the build–own–operate (BOO) model at Garautha Substation (400/220 kV) in Jhansi, Uttar Pradesh.
The project marks Sunsure’s first long-term agreement for power supply through BESS. Through the agreement, Sunsure will deliver four 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 marks a first-of-its-kind BESS agreement where instead of fixed monthly rates, billing is based on fixed tariff (INR/kWh) of discharged energy.
“Round-the-clock renewable energy is the need of the modern, growing India. The next generation of clean energy infrastructure will not be the one that works only when the sun shines or when the wind blows—but one that works when India needs it the most,” said Shashank Sharma, founder, chairman & CEO of Sunsure Energy. “At Sunsure, we’ve spent the last 24 months quietly building capabilities for that future. 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.”
Sunsure Energy has 500 MW of operational assets, with another 2.5 GW under construction across states like Maharashtra, Uttar Pradesh, Tamil Nadu, Rajasthan, and Karnataka. It targets 10 GW portfolio by 2030.
In Uttar Pradesh, Sunsure Energy has an operational solar capacity of 240 MWp supplying power to industrial customers in the state. The company also has another 210 MWp of projects under advance stages of development.
