Electricity supplies may come under strain this winter in Finland, France and Southern Sweden, according to ENSTO-E's winter outlook.
ENTSO-E (the European Network of Transmission System Operators for Electricity) is a cooperation body for European transmission system operators (TSOs).
"Close follow-up is needed on the uncertainties around nuclear availability in France, Sweden and Finland, as well as coal supply in Germany and Poland," the group said in its winter outlook published on Thursday.
The body said that while it expected the Nordics to have enough electricity to manage the winter, glitches at electricity-producing facilities or transmission systems could lead to shortages.
The Finnish Transport Infrastructure Agency on Friday meanwhile reported that some rural roads may darken this winter in an effort to prevent electricity shortages.
Should officials decide to cut roadside lights, the measure would be taken during peak electricity usage hours—that is—in the mornings between 7am and 9am and in the evenings from 4pm to 7pm.
Efforts would be made to keep busy areas lit, such as those near intersections and schools, as well as in tunnels, according to the agency.
People in Finland, however, appear to be taking the government’s advice to use less electricity. National grid operator Fingrid on Thursday said electricity consumption in November was down nine percent year-on-year in Finland, according to preliminary figures.
