"We are up and running, yes. The short and simple answer is that prices are high now, and that is why the market has called us out," Björn Magnusson, communications manager for Karlshamnsverket, told Sveriges Television.
The plant, which was previously part of Sweden's electricity reserve, only runs when the electricity price is high enough because production costs are high.
The last time Karlshamnsverket was in operation was for a few days at the beginning of December, but now one of the plant's two units has started up again due to the cold and calm weather, SVT reports.
The electricity price on Monday is 1.50 SEK/kWh on average, the same across the country, according to the electricity exchange Nord Pool.
