Yes, germany is already doing that with electric cars. I have a Wallbox in our garage, with seperate electric because it is sadly 300 meters away from our house. So I can't use our solar. However this connection is terminated via GSM when many people are using the grid. This is usually around morning and evening. If the grid isn't exhausted they will turn the electricity back on. I really like this approach. It works well.

It would be nice, if this would be mandatory for big official mining operations. Pretty sure they would just move somewhere else but still.
