Multiple have been built, for cheaper than a nuclear reactor, losing zero capacity within a decade.
I present you Nant de Drance [0]:
- 20 GWh of storage capacity
- 900 MW of power
- 2.1 * 10^9 USD cost
This kind of project cannot be replicated just anywhere. Other fairly cheap large scale scalable electricity storage solutions do exist.

- TheLoafOfBread 4y agoShow me where you will build it in Poland or even Germany?
- markvdb 4y agoGoldisthal [0], Markersbach [1] and Żarnowiec [2] exist and are quite significant. Also, the Młoty pumped hydro storage project is being worked on again after 33 years. The best sites for this have been taken already, but there is still some potential in new sites and optimisation of existing ones.
