Sunsure Energy, NVVN Ink 500 MWh BESS Deal for Peak Power Supply to UPPCL

Sunsure Energy has signed a Battery Energy Discharge Purchase Agreement (BEDPA) with NTPC Vidyut Vyapar Nigam Ltd (NVVN), a wholly owned subsidiary of NTPC Ltd, for setting up a 125 MW / 500 MWh standalone Battery Energy Storage System (BESS) in Uttar Pradesh. The power will be supplied to Uttar Pradesh Power Corporation Ltd (UPPCL) under a 15-year contract.

The facility will be developed under the Build–Own–Operate (BOO) model at the Garautha Substation (400/220 kV) in Jhansi, Uttar Pradesh. Sunsure will deliverfour hours of on-demand power between 6 PM and 10 AM, enabling UPPCL to meet peak demand at competitive tariffs.

The agreement marks India’s first tariff-based BESS energy purchase contract, where billing will be based on a fixed ₹/kWh discharge tariff, rather than fixed monthly capacity charges.

RTC-Need Of The Hour 

Commenting on the development, Shashank Sharma, Founder, Chairman & CEO, Sunsure Energy, said:

“Round-the-clock renewable energy is the need of a modern, growing India. At Sunsure, we have evolved from pure solar offerings to hybrid systems with BESS, enabling customers to access clean energy during peak hours. Our partnership with NVVN for India’s first-of-its-kind BESS deployment is a significant milestone towards achieving the country’s renewable energy goals.”

Sunsure currently operates 500 MW of renewable assets, with 2.5 GW under construction across Maharashtra, Uttar Pradesh, Tamil Nadu, Rajasthan, and Karnataka. The company is targeting a 10 GW portfolio by 2030.

In Uttar Pradesh, Sunsure already supplies 240 MWp of solar capacity to industrial customers across FMCG, ceramics, metals, electronics, data centers, and chemicals, with another210 MWp under development.
