Just as a curiousity. Is this negative power often enough to make a business model of battery supply to the power system feasible? I mean having a company with a massive bank of batteries. When power goes negative they try to take as much as they possibly can from the network and when it goes positive they try to sell it back at the higher rate. Essentially win-win. You only power up on negative days and you sell when you make money, otherwise you just sit on it. And since you were paid to take the energy in the first place losing it over time when you don’t sell isn’t a loss because you didn’t pay for it at all.
