> They are not necessarily a good thing Indeed. I would even go as far as to say they are never a good thing. They indicate that the plants are having to spend money to keep things running, and that extra cost is carried over to the very same consumers who for short periods get “free” power or get paid to absorb the load. And since the scenario of having negative prices is far from efficient the total cost is still positive. So unless you have a very unusual completely selective powerusage you end up paying more net than if the prices had remained positive but slightly lower throughout.
