Grid-scale energy storage system set up in Delhi

India’s first grid-scale battery-based energy storage system has been installed at Tata Power Delhi Distribution Ltd’s (Tata Power-DDL) sub-station in Rohini, Delhi.

A statement from the company claimed that this is South Asia’s largest grid-scale energy storage system.

Sanjay Banga, CEO of Tata Power-DDL, said this would address the key challenges in the areas of peak load management, system flexibility, frequency regulation and reliability of the network.

“The 10 MW grid-connected system, owned by AES and Mitsubishi Corporation will pave the path for wider adoption of grid-scale energy storage technology across India. Fluence, a market-leading supplier of energy storage technology jointly owned by Siemens and AES, supplied its state of the art Advancion Technology for the project,” a Tata Power statement said.

This 10 MW project is located at Tata Power Delhi Distribution Ltd’s sub-station at Rohini and will provide grid stabilisation, enhance reliability and protect critical facilities for 2 million consumers served by the company.

Fast-ramping energy storage like the Delhi system can be built in a matter of months to provide critical flexibility to wherever needed on India’s grid. In comparison, older technologies such as pumped hydroelectric energy storage can take years to build and are highly dependent on geographical locations. Battery-based energy storage also uses no water and produces no emissions, the statement said.
