EV fast charging station tells you when its power is at its cheapest and greenest

[Think. Again.]

10. Hi! just getting back to you....

...about that info you asked for.

Here's a quick and easy wikipedia link to start looking for a list of large, grid energy storage plants in operation.

The list at the link below has about 60 large storage facilities listed with lots of additional info, but it doesn't include ANY of the H2 production plants that can store energy for longer periods.

Good luck!...

List of energy storage power plants

This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual energy storage plants augment electrical grids by capturing excess electrical energy during periods of low demand and storing it in other forms until needed on an electrical grid. The energy is later converted back to its electrical form and returned to the grid as needed. Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in List of pumped-storage hydroelectric power stations and not included here. This article list plants using all other forms of energy storage.
