Pumped storage and grid scale batteries provide that at much cheaper cost overall. Nowhere near as much is needed as people think either.

- ch4s3 4y agoWhere are grid scale batteries doing that today?
- ncmncm 4y agoBefore a thing has been built, it needs to be built. Do you need this explained further? The overwhelming bulk of utility storage will not be batteries, because that is the most expensive alternative. Utility storage will be whatever is cheap and locally practical.
- ch4s3 4y agoThat’s basically what I meant.

Pumped storage is generally a lot more economic and can store a lot more than batteries but it cant be built quite as quickly & is somewhat geographically dependent. It takes 4-5 years to deploy rather than months.
