Sunsure Energy, NVVN Ink First-of-its-Kind 500 MWh BESS Deal at Jhansi’s Garautha Substation

Renewable energy company Sunsure Energy has announced a pioneering agreement with NTPC Vidyut Vyapar Nigam Ltd (NVVN) to supply 500 MWh of peak power to the Uttar Pradesh Power Corporation Ltd (UPPCL) through a large-scale battery energy storage system (BESS).

The Battery Energy Discharge Purchase Agreement (BEDPA) secures a capacity of 125 MW/500 MWh under a 15-year contract, marking the first time in India that a BESS-based power supply deal has been structured in this way. Under the build-own-operate model, Sunsure will install the standalone system at the Garautha substation in Jhansi, Uttar Pradesh.

This arrangement will allow Sunsure to deliver four hours of on-demand power daily between 6 pm and 10 am, enabling UPPCL to meet peak demand with clean energy at a competitive fixed tariff. Unlike traditional fixed monthly rate models, the pact introduces an innovative per-kWh discharged energy billing system, a first in India’s energy storage sector.

Sunsure Energy’s Founder, Chairman & CEO Shashank Sharma highlighted the company’s evolution from solar-only projects to advanced hybrid renewable solutions with storage. He noted that the deal reflects a major step for utilities as well, transitioning from pure solar and hybrid tenders to nation-leading energy storage deployment.

The agreement is being seen as a milestone in India’s renewable energy journey, strengthening grid reliability while helping replace fossil fuel-based generation during peak demand hours.
