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.
