Base power is doing something similar in Texas. AFAICT, they take a loss on the equipment, charge the batteries when electricity prices are cheap, then sell power out of the batteries when prices are high and keep the difference. The homeowner enjoys only most likely having backup power.

I mean, the electricity still has to be generated. That still costs money. This whole thing only works as long as there is someone willing to buy at the high prices and off peak demand stays low enough to keep prices cheap. Eventually there’s no more road to kick this can down.

What do you mean? The opportunity for energy arbitrage will go away if energy prices are constant. Right now they aren’t, and I don’t really see how they would become constant based on the physics of producing and consuming energy.
