The UK and Ireland subsidiary of the Virginia-headquartered AES Corporation has signed an agreement with a Northern Irish government agency to build a 100MW battery storage array.

Utility San Diego Gas and Electric (SDG&E) and US-based storage provider AES Energy Storage, a subsidiary of AES Corporation, have completed what they claim to be the world’s largest lithium-ion battery energy storage facility in Escondido, California.

What is thought to be India’s first grid-scale energy storage array will be developed and delivered by a joint partnership between system provider AES and Mitsubishi Corporation, it was announced.

An Arizona scheme to study the use of energy storage and smart inverters in integrating solar to the grid has contracted the deployment of 4MW of AES Energy Storage’s lithium battery systems.

Brian Perusse, vice president of AES Energy Storage and Jim Avery, chief development officer of SDG&E discuss the largest battery-based storage system in the US, set to stand at 30MW in California.

Energy storage provider AES Energy Storage has signed a multi-year agreement for Korean battery supplier LG Chem to provide 1GWh of lithium-ion battery capacity for AES’s energy storage systems, which a US analyst has said could take around seven to eight years to install and be worth an estimated US$300 million.
