Pumped storage hydro is great, but it is limited to places that have the right terrain.

- Nition 10y agoI wonder what the cost would be of pumped storage in just like a massive water tank on a hill, or a big manually dug out lake, rather than in somewhere that could actually be a natural lake.
- jccooper 10y agoTaum Sauk, an artificial pumped storage facility which famously failed, was rebuilt to 3600 MW·h for $490 million. So that was like $136 per kwh capacity, though I think they didn't have to do much for the lower reservoir (which was built in the 60s). Seems to be a lot better than batteries, though still requires appropriate terrain. https://en.wikipedia.org/wiki/Taum_Sauk_Hydroelectric_Power_Station https://en.wikipedia.org/wiki/Taum_Sauk_Hydroelectric_Power_...
