Utility Portland General Electric (PGE) has announced the procurement of a 75MW battery energy storage system (BESS) project in the state of Oregon, building on another 400MW round last month.

After China connected a huge battery to a project combining solar, wind and other generation sources, a US utility project has just been announced which will likewise combine solar and wind with a grid-scale battery.

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.
