It’s no secret that the U.S. electricity generation system is desperately in need of reliable energy storage to back up the vast amount of intermittent renewable resources being added. It’s also a fact that pumped storage hydropower is the single largest source of this backup storage, at well over 90% of total available utility-scale energy storage.
So which company will be the first to succeed in building new pumped storage in the U.S.? I don’t have a crystal ball, so read on to see my educated predictions.
