High electricity prices loom as Swedish nuclear power faces summer of disruptions

Sweden faces a summer of unusually high electricity prices due to widespread problems plaguing its nuclear power plants. More than half of the country's nuclear production is currently offline, with several reactors forced to reduce output and repeatedly postpone their restarts.

Recent weeks have seen further complications. Both reactors at Ringhals have encountered additional issues, with three-quarters of their normal production expected to be offline until mid-August. Oskarshamn's only reactor has been out of service since March for repairs, with a restart currently anticipated at the end of June.

These domestic nuclear issues are compounded by external factors. Drier-than-normal weather has reduced hydroelectric power generation in Sweden and Norway, while high global gas prices, influenced by the conflict between Iran, Israel, and the US, are also driving up electricity costs in southern Sweden.

Projections based on the futures market indicate that summer electricity prices will be double those of last year and the highest since 2022. In southern Sweden (electricity area 4), prices are forecast to average 75 öre/kWh, compared to 53 öre last summer. While prices in northern Sweden are expected to be lower, they are also seeing significant percentage increases. Analysts predict that the high prices will persist throughout the year, with the autumn looking "unusually expensive."
