This is in fact a very good feature. When power is cheap or negative it's because there is more generation than load in some segment of the grid. To fix this you can tell people to stop generating, you can tell people to start loading, or you can just drop the price and let both happen on their own.
There are targetted ways this is done when the difference is so big it threatens grid stability, but its often better to let the market handle the gross imbalance on longer timescales when grid stability is not threatened.
There are some things markets are very good at. This is one of them.

Ironic in a thread about the market making up a totally imaginary generation surplus.
10-20% of Finnish retail customers are on spot market based contract, and stand to save up to something on the order of 0.40€/kWh consumed (net after taxes and fees) off their electrical bill for the reminder of the day. I suppose every market-rational consumer would have a 10kW electric space heater outside melting snow on the ground, maxing out their supply.
It's actually particularly important that prices be able to go negative in an electricity market, because it's physically impossible to store electricity: it must be generated and consumed at the same moment. "Electricity storage" is shorthand for "conversion to and from a different kind of energy", which from the perspective of the grid is just a kind of consumption or generation. And if there is too much unused power on the grid, it will damage it.
No the opposite is the case. How would you expect a zero minimum price to be enforced? All waste products would have to be disposed by the government for free and the thing is that this costs money. Negative prices signal a desire to get rid of something.

Thanks, the 970 Evo Plus is a solid unit. I have one in my old PC, along with a 980 Pro. Went 990 Pros on my new, they didn't go 30 minutes before I had the firmware updated. :-) Very good performers.
(I always keep an eye on things like firmware updates).
