Water (pumped hydro) storage is really great, but only works well at scale where the geographic features support it.

- stucomp 6y agothe article mentioned desalinating water as a way to use negatively priced energy and storing the value in a commodity for sale or consumption at a later date, not pumped hydro storage
- tuatoru 6y agoStored water for hydro power generation is also a commodity for later sale or consumption.
- robocat 6y agoExisting hydro (not pumped) also acts as storage: a decrease in the load on a normal hydro dam means more stored power... and all the infrastructure exists including grid connection.
- abe_m 6y agoIt a lot of cases that doesn't happen. The water levels in the headwaters and the amount of flow on the downstream river are controlled with goals other than power production. Like not causing floods, and having enough water depth for navigation. In Ontario, Canada, if the plant doesn't run at capacity, generally the water is sent through the spillway without generating power. I'd assume that to be common in many hydro-electric installations.
