South Asia’s Largest Grid-Scale Energy Storage System Goes Online

The project was developed in collaboration with AES India and Japan’s Mitsubishi Corporation.

Tata Power Delhi Distribution Limited (TPDDL), a joint venture between Tata Power and the Government of NCT of Delhi that distributes electricity in North & North West parts of Delhi, has inaugurated South Asia’s Largest Grid-Scale Energy Storage System in Rohini.

The project was developed in collaboration with AES India, a subsidiary of US-based AES Corporation, and Japan’s Mitsubishi Corporation. The work on the project began on January 23, 2018. Battery-based energy storage enables electricity to be stored and then delivered within milliseconds, reducing instability of the electric grid and enabling more energy to be captured and delivered on demand.

AES and Mitsubishi Corp will own the Advancion storage solution being supplied by Fluence, an energy storage technology and services company owned by Siemens and AES. This 10 MW project is located at  TPDDL substation in Rohini, Delhi and will provide grid stabilisation, better peak load management, add system flexibility, enhance reliability and protect critical facilities for 2 million consumers served by the company.

“Tata Power’s collaboration with AES and Mitsubishi is one of the significant milestones in the Indian power sector,” said Praveer Sinha, CEO and Managing Director of Tata Power. “Grid-scale energy storage will pave the way for ancillary market services, power quality management, effective renewable integration and peak load management of Indian grids.”

“Battery-based energy storage has an essential role to play in helping India realize its vision for a more sustainable energy future,” said Mr. Andrés Gluski, AES President and CEO. “AES has been committed to delivering safe, reliable and affordable power in India for the last 27 years and we’re proud to bring the country’s first major grid-scale energy storage solution online and open the market for the use of battery storage technology in India.”
