Sunsure Energy, a renewable energy company, has made a significant announcement regarding 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). This will be achieved through a large-scale battery energy storage system (BESS), marking the first time in India that a BESS-based power supply deal has been structured in this way.
The agreement, known as the Battery Energy Discharge Purchase Agreement (BEDPA), secures a capacity of 125 MW/500 MWh under a 15-year contract. Sunsure will install the standalone BESS at the Garautha substation in Jhansi, Uttar Pradesh, under the build-own-operate model. This arrangement will enable Sunsure to deliver four hours of on-demand power daily between 6 pm and 10 am, allowing UPPCL to meet peak demand with clean energy at a competitive fixed tariff.
The pact introduces an innovative per-kWh discharged energy billing system, a first in India’s energy storage sector. This differs from traditional fixed monthly rate models, providing a more flexible and efficient billing system. Sunsure Energy’s Founder, Chairman, and CEO, Shashank Sharma, highlighted the company’s evolution from solar-only projects to advanced hybrid renewable solutions with storage.
The agreement is seen as a milestone in India’s renewable energy journey, strengthening grid reliability while helping replace fossil fuel-based generation during peak demand hours. It reflects a significant step for utilities, transitioning from pure solar and hybrid tenders to nation-leading energy storage deployment. This deal is expected to have a positive impact on India’s renewable energy sector, promoting the use of clean energy and reducing reliance on fossil fuels.
The BESS-based power supply deal is a pioneering step towards a more sustainable and efficient energy system in India. It demonstrates the potential for renewable energy to meet peak demand, reducing the strain on the grid and promoting a cleaner environment. As India continues to transition towards a more renewable energy-based economy, agreements like this will play a crucial role in shaping the country’s energy landscape.
