Work on ‘world’s biggest Li-ion ESS’ begins in Southern California

Work has begun on what it said to be the biggest lithium-ion energy storage system, with the ground-breaking of a 100MW/400MWh project for the Alamitos Energy Center in Southern California.
The system by AES Alamitos, a subsidiary of AES Corporation, will use Advancion 5 batteries and control systems from Fluence— the joint venture between Siemens and AES.
