California investor-owned utility (IO) Pacific Gas & Electric (PG&E) has furthered its commitment towards the state’s mandated target for energy storage deployment by utilities, putting 165MW of contracts forward to regulator California Public Utilities’ Commission (CPUC) for approval.

Oregon-based utility company Portland General Electric intends to spend between US$50 million to100 million on around 39MW of energy storage, company executives have revealed.

The utility has integrated battery energy storage systems into California’s electricity market CAISO for the first time.
