Finland’s electricity consumption has climbed to the highest level ever recorded as freezing weather combines with low power prices, according to the national grid operator Fingrid. Fingrid said peak demand reached a new record on Thursday morning, with average power use over a 15-minute period rising above 15,000 megawatts. The figure may increase further during the evening as heating demand remains high. The surge comes during an extended period of sub-zero temperatures across the country.
