Wouldn't you need two reservoirs in that case? Otherwise where is the water being drained down to take advantage of the potential energy?

- pfdietz 4y agoYes, of course. Off-river pumped hydro involves two reservoirs.
- nirimda 4y agoI think the confusion is a couple of comments up you said "There's a plan to put a reservoir for one on top of a mesa in the desert in Arizona" which is really confusing since of course they're planning to put a pair of reservoirs for one in the desert in Arizona. I guess only one is on top of the mesa though.
- sidewndr46 4y agoSo at that point why use a river? Couldn't you just use ocean water? It's comparatively "free" and we aren't going to run out anytime soon.
- BurningFrog 4y agoWith a high enough plateau near an ocean, that should work. I think those places are really rare though.
