Los Angeles Department of Water and Power (LADWP) announced Wednesday that it has selected Doosan GridTech and its partner, KTY Engineering, to provide LADWP’s first battery energy storage system (BESS) with a capacity of 20MW at its Beacon Solar Plant in Kern County, California.

Renewable Energy Systems ranks alongside US firm AES at the top of a new leader-board of energy storage systems integrators; its two new National Grid contracts will see it top the table, it says.
