My dad said when he was a young engineer nuclear and space was going to be the future and it didn't pan out. Friends dad was a nuclear engineering professor and said I retired just in time.

I think battery storage costs something like $100/MWh or 10 cents per kwh. (Don't quote me/find a reliable source). Batteries increase demand when there is excess supply and increase supply when there is under supply. The result is lower price swings. The price differentials are higher than the cost of storage which makes them balance sheet profitable. The notable thing is the buy low sell high cycle is 24 hours, not weeks or months. From an arbitrage point of view that's exceptionally attractive. Better than buying wheat futures in the spring and trying to offload them in August and sometimes losing your shirt.
