If you have a Tesla power wall, I believe you can set it up to do this. Basically go power wall (house battery) to house during expensive times of electricity.

If you have a Tesla power wall, I believe you can set it up to do this. Basically go power wall (house battery) to house during expensive times of electricity. And then charge the battery back up during cheap electric times. I think even 10% of the grid with such a system would do a lot to take the edge off peak demand, as all of those goes guys go to 0% usage.
