Grid-connected Li-ion battery based energy storage system launched in Delhi

Nexcharge in collaboration with Tata Power Delhi Distribution Ltd (TPDDL) inaugurated India’s first grid-connected Li-ion battery-based community energy storage system at Rani Bagh, Delhi, on March 27, 2021.

The 0.52 MWh battery energy storage system at TPDDL’s Rani Bagh substation will provide peak shaving, VAR compensation, and deviation settlement mechanism based on frequency response at substation level with power backup to preferential consumers in case of a grid outage, a release by Nexcharge said.

Nexcharge executed the project utilizing a Global Project Team approach wherein teams from US, Europe, and India collaborated towards the project.

Nexcharge, an Exide Leclanche Energy Pvt. Ltd. brand, is an exclusive joint venture in India between Exide Industries Ltd, the country’s largest-selling battery company, and Leclanche SA, the Swiss large-format lithium-ion cell conglomerate,

The 0.52-mw hour grid-connected system owned by Exide Industries Ltd and Leclanché SA will provide the path for wider adoption of grid-scale energy storage technology across India.

Speaking about the initiative, Stefan Louis, Chief Executive Officer, and Chief Technology Officer Nexcharge said, “Battery-based energy storage (BESS) provides the agility to better integrate intermittent solar and wind energy resources into India’s electric grid and ensure high-quality power for consumers. A Community Energy Storage System like this will ensure consumers get to experience better levels of stability, reliability, quality, and control. Both customers and distributors will benefit from this service. We are very happy to partner with Tata Power DDL to set up this new 0.52 MWh grid-connected system which will pave a new path for wider adoption of grid-scale energy storage technology across India. It’s another step towards all Indians accessing smart sources of energy.”

Battery storage systems are emerging as a potential solution for integrating solar and wind renewables in power systems across the globe. In light of the ongoing climate change crisis, renewable and sustainable sources of energy are the need of the hour, especially when India’s commitment to the contribution has been touted at 175 GW by 2022, the release observed.
