yeah, the only case where power companies would pay people to consume power would be the event that they are over producing, and have nowhere for it to go, which would be actively harmful, nuclear plants will lose money if you aren't selling energy, but it doesn't make sense to buy that energy yourself, you would just let it burn. Or maybe the government would subsidize burning it, i don't know. Generally this kind of thing happens in a really unstable electricity market. It's not that ideal.

Energy storage is going to be a huge business though, i think batteries are probably going to be common than people think, compared to things like thermal storage, though i guess it all depends on how expensive batteries are in comparison more than anything.
