It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
In Finland they've been developing small scale reactors about the size of a shipping container but they're not intented to produce electricity but instead just heat water and then push it into the district heating grid. This way the powerplant would also be much simplier to produce and maintain as well as safer due to the lower pressures and temperatures it operates at. Basically a nuclear powered kettle.
That really fucking cool! Whoever came up with that application for nuclear power is a genius.
