Not realy. There are TWO markets for electricity. One is the Day Ahead system, where producers and consumers agree on who runs what generators and who consumes how much, in 24 hours. The real time market, meanwhile, covers who it is who has to adjust his production or consumption to cover the difference between what everyone thought would happen 24 hours ago and what happens now. The real time price hits negative, but it's only the delta between real time volume and day-ahead volume that's traded at the negative price. And it's the people who are turning knobs, being paid by those who are sticking to what they planned to do at the Day Ahead market.
