The use of electric storage is a critical component to the integration of intermittent clean energy technologies on the electric grid. That being said, however, just mentioning Pumped Storage Hydro (PSH) to some stakeholders often unleashes a torrent of criticism of how its use adversely affects riverine and lake aquatic systems. Nevertheless, PSH deserves another look, especially the Closed-Loop variety which does not affect rivers and lakes. See article in the Natural Gas and Electricity Journal.
