Even on Friday, there was a sale on electricity, with an average price of six öre and with many individual hours with theoretical negative prices, also in all four electricity price areas.
When electricity consumption, as usual, decreases during the weekend, it will be extra cheap on Saturday and probably also on Sunday.
But it has absolutely not looked like that earlier in the month, at least not in southern Sweden (electricity area 4). The price differences have been unusually large. While electricity in the rest of Sweden has cost around ten öre for several days, people in Skåne have had to pay over one krona per kilowatt-hour (kWh) on the same day.
A major contributing factor is that the transmission capacity between electricity areas 3 and 4 is reduced due to maintenance work. A nuclear reactor at Ringhals shut down due to maintenance is also negatively affecting the possibility of electricity transmission to southern Sweden, according to Svenska kraftnät.
However, there will never be a question of negative prices for the end consumer. On top of the stock market price, electricity tax, VAT, and network fees of over one krona/kWh are added.
According to, among others, the electricity trader Tibber, there have never been as many hours with negative prices as during the past summer. More and more wind and solar energy are making prices more and more volatile.
