India commissions its first grid-connected lithium-ion ESS on its renewable energy journey

Wed, 04/07/2021 - 09:18 -- Paul Crompton

Nexcharge, a joint venture between Exide technologies and Leclanché, has inaugurated India’s first grid connected lithium-ion energy storage system to deliver better levels of stability, reliability, quality and control.

The 150kW/528kWh Community Energy Storage System (CESS) was deployed in collaboration with Tata Power Delhi Distribution (TPDDL) at a substation in Rani Bagh, Delhi, on 27 March.

The key feature of the system is to support the Distribution Transformers in managing the peak load, voltage regulation, power factor improvement, frequency regulation and deviation settlement mechanism. 

The system also offers black start capabilities that can provide 150KW for four hours duration to critical services like hospitals, commercial complexes, Delhi Jal Board. 

The CESS energy storage will allow better integration of solar and wind energy resources into India’s electric grid.

Stefan Louis, chief executive officer and chief technology officer at Nexcharge said he hoped the system would pave a new path for wider adoption of grid-scale energy storage technology across India. 

Ganesh Srinivasan, chief executive officer – TPDDL, said: “Instead of building humungous infrastructure of transformers and electric equipment, CESS can be used to meet peak demand while storing surplus power. I believe wider adoption of such ‘CESS’ will help in balancing the load curve of discoms and make them future ready.”

India aims to 225GW of renewable energy generation by 2022. Key to this will be energy storage systems to provide the flexibility to better integrate solar and wind energy resources into India’s electric grid and ensure security of supply.
