A single hour on Monday evening, the electricity price in southernmost Sweden was the highest so far this year, at 4.50 kronor per kilowatt hour. The daily average landed at 1.50 kronor, the highest since February.
Also in other electricity areas, prices have been higher this week compared to last week.
Five of eleven reactors
We have had high pressure which has made it very low wind power, says Johan Sigvardsson, electricity analyst at Bixia.
In addition to the fact that it has blown poorly, the price is also affected, according to Sigvardsson, by the fact that much nuclear power is out of operation, both in Sweden and Finland.
In total, five of eleven reactors are standing still.
It would have been two of eleven reactors out of operation actually, but there have been extended maintenance in different places. They are a bit temporary stops, he says.
Windy next week
Next week, both reactor 4 in Ringhals and one of two reactors at the Lovisa nuclear power plant in Finland are expected to be back in use again.
It will be a better situation next week, above all it looks like it will be very windy on Monday and Tuesday, says Sigvardsson.
He also notes that it is still summer temperatures outside and that consumption is therefore low.
