The battery plant will be operated by Tata Power Delhi Distribution Limited (Tata Power-DDL), but AES and Mitsubishi will develop and own the 10MW array based on the Advancion energy storage system developed by AES. This will handle peak load management, increase system flexibility and support high levels of reliability for more than 7 million customers in the region.
“For a rooftop solar program to be successful, it is important for the distribution network to integrate it with energy storage solutions to take care of power generation spikes and fluctuations, system stability, reactive power compensation and grid emergencies," said Praveer Sinha, CEO and MD of Tata Power-DDL. "Tata Power-DDL has implemented many smart grid technologies and is privileged to implement India’s first utility-scale 10 MW storage solution with AES and Mitsubishi Corporation. This will prove to be an important learning for developing integrated rooftop solar and storage solutions for India,” .
India plans to install 160,000 MW of solar and wind generation over the next five years and energy storage will play a critical role in ensuring its integration into the grid.
“Rapidly growing generation capacity will need large scale deployment of energy storage for transmission decongestion, protecting processing plants from grid frequency and voltage drop triggered outages,” said Rajendra Shrivastav, President of AES India. “We expect electricity regulators in India will understand and appreciate the value of ancillary services these storage systems bring into the system operation.”
The Advancion energy storage array will be constructed in Rohini, Delhi, at a site operated by Tata Power-DDL and start operation by the end of the year. AES has 166 MW currently in operation and 270 MW in construction or late stage development across seven countries, four continents, and eight different power markets.
