Cool, thanks. I wasn't aware that pumped hydroelectric had this great installed capacity. Those are very big numbers. Of course, it isn't an either/or proposition, since pumped hydroelectric is limited by geography. Battery-supported grid levelling can also be installed locally at each residential solar project, which makes adoption less of a political case.
