On Sunday, there were negative prices for electricity throughout the country, reports Sveriges Radio Ekot.
In electricity area 1, the spot price averaged minus 1.20 öre per kilowatt-hour, while in the other three electricity areas it was minus 7.89 öre per kilowatt-hour.
The explanation is a combination of strong winds and plenty of sunshine.
These two production types cannot shut down even if the electricity is not in demand, it has to go out on the grid, says electricity price analyst Bengt Ekenstierna to the radio.
Then it's supply and demand that govern. When nobody wants as much electricity as is produced, the price drops.
But the negative prices did not last long. Already by 5 pm on Sunday, they rose to positive levels again. On Monday, the price is around 53 öre per kilowatt-hour in southern Sweden.
