Tata Power, AES Corporation and Mitsubishi Corporation recently inaugurated India’s first grid-scale battery-based energy storage system in Rohini, Delhi.
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, an energy storage technology company jointly owned by Siemens and AES, supplied its “Advancion” technology for the project.
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.
India has the ambitious vision of installing 225 GW of renewable energy generation by 2022. 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.
This 10-mw project is located at Tata Power Delhi Distribution Ltd.’s substation in Rohini, Delhi and will provide grid stabilization, 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. 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,” according to Praveer Sinha, CEO and Managing Director of Tata Power.
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.
