I'm not sure you'd need to pay much. Already I've seen power prices go negative in TX on ERCOT's site. I expect that is somewhat accounting only. I thought some power is priced ahead and committed at a given price and then there is the "open market" which covers surprises. So if wind/solar has a better than expected day, there are days they get nothing for it. So I'd expect those days they'd take a ten bucks a MWH and be ahead.
Right, and it will have extremely good days because of seasonal variation. If we size our systems to provide most of the winter load, there will be a lot of excess power in the summer, and while batteries will continue to get cheaper, I don't think they'll get cheap enough to timeshift from summer to winter. Long-distance power transmission also doesn't do much to address that problem, unless it's really long distance.
