Swedish grid operator predicts less severe power shortage this winter

Grid operator Svenska Kraftnat reported on Monday that Sweden will face less of an energy shortage this winter than previous years, as higher prices have reduced demand. However, southern Sweden still has a deficit.

Transmission system operators (TSOs) estimate a power balance of 600 megawatts per hour during peak hours under normal temperatures, but warn of a deficit of 600 MWh/h in the event that winter is colder than usual.

The report, which focuses on the Swedish power balance for 2025, states that Sweden won't need to import net imports in order to meet peak demand.

TSO releases a new report each year. It had previously predicted a 3,800-MWh/h winter deficit in 2025/26, but now has lowered expectations for peak demand.

Eva Vitell of Svenska Kraftnat’s System Division said that the increased awareness about electricity prices among customers was largely responsible for this.

The Swedish energy ministry reported that the demand for electricity in Sweden has fallen from 140 terawatt-hours (TWh), which was the case in the years prior to the 2022 crisis. This led to record high prices.

The TSO reported that consumption last winter, which was described by meteorologists as being unusually mild, peaked at 22,5 MWh/h (measured in watt-hours per hour) on January 13. This is the lowest winter peak recorded since records began for 1997/98.

Northern Sweden is experiencing a surge in wind energy installations, creating an electricity surplus.

Svenska Kraftnat predicted a power imbalance in southern Sweden this winter of -7.700 MWh/h in the event of normal temperatures. The shortfall is expected to be compensated by power imports and flows from northern Sweden. (Reporting and editing by Anna Ringstrom, Jacqueline Wong and Nora Buli)
