AES and Mitsubishi Corporation have commissioned a 10MW energy storage system in the Indian city of Delhi.
The lithium ion battery, installed at Tata Power Delhi Distribution Limited’s Rohini substation, is the country’s largest installation of its kind.
The battery will help manage peak loads on the grid, as well as provide system flexibility and reliability that will benefit more than two million energy consumers.
The 10 megawatt hour capacity energy storage system, owned by AES and Mitsubishi Corporation, uses technology supplied by AES-Siemens joint venture Fluence.
India aims to install 225GW of renewable energy generation by 2022.
According to AES battery-based energy storage provides the flexibility and agility to better integrate intermittent solar and wind energy resources into India’s electric grid and ensure high-quality power for consumers.
Tata Power chief executive Praveer Sinha said: “Tata Power’s collaboration with AES and Mitsubishi is one of the significant milestones in the Indian power sector.
“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.”
AES chief executive Andres Gluski said: “Battery-based energy storage has an essential role to play in helping India realise its vision for a more sustainable energy future.”
Integrating solar and wind power with storage can increase renewable resources’ value by providing firm, predictable and dispatchable blocks of energy.
