Renewable energy developer Serentica Renewables has invited expressions of interest (EoI) to set up interstate transmission system-connected Battery Energy Storage Systems (BESS) to supply 800 MWh of battery capacity to Serentica’s round-the-clock projects.

The company said it is seeking technical partners to supply BESS capable of delivering reliable energy storage. It is executing 4 GW of projects and will deliver 2 GW per year of round-the-clock capacity to some large industrial customers in India.

BESS aggregators, long-duration battery suppliers/solution providers, and renewable energy developers worldwide can submit bids.

The last day to submit the bids is July 30, 2024. Bids can be submitted here.

The BESS should be at least 51% owned by the BESS provider.

The projects should be split between 200 MW/400 MWh of 2-hour storage and 100 MW/400 MWh of 4-hour storage.

Serentica will ink a contract with the BESS projects to procure the BESS capacity annually under a 12-year service agreement starting June 2026.

In an interview with Mercom India in February, Akshay Hiranandani, CEO of Serentica Renewables, delved into the company’s ambitious plans for installing 4 GW of wind and solar capacity across Rajasthan, Maharashtra, and Karnataka.

He noted that the company recently embarked on a collaborative effort centering around a standalone energy storage offtake contract. This strategic move is anticipated to position Serentica as a key player in delivering 1,500 MW of uninterrupted power, specifically emphasizing industries highly sensitive to power disruptions.

In January, Serentica secured ₹35 billion (~$425 million) for its round-the-clock renewable energy project in India from a consortium of three international banks and three Indian lenders. The deal is expected to allow the company to fund the development of its 530 MW wind-solar hybrid project that will come up in Rajasthan and Maharashtra.

Earlier this year, Serentica won 200 MW capacity in NTPC’s auction to supply 3 GW of firm and dispatchable renewable energy from inter-state transmission-connected projects.
