That's where I think things like Tesla's Powerwall becomes so handy. Imagine 95 kWh just sitting there on your wall. Or in your Model-S. When there's an adverse power event, use your battery. Or, sell it back to the grid if there's money to be made.

Having a massive virtual peaker plant (https://en.wikipedia.org/wiki/Peaking_power_plant) is a neat idea. Telsa, another new business idea for you!
