Should nations extend the operating life of existing nuclear power plants to ensure electricity reliability?
Released in June 2026, the report analyzed strategies to address projected electricity shortages in Sweden and Finland. It assessed how extending the operational life of existing nuclear reactors could help bridge massive generation gaps expected by 2045.
Why it matters
Rising electricity demand from industrial electrification, hydrogen production, and data centers requires massive increases in power capacity. Without extending the life of current nuclear plants, both nations face severe energy deficits.
Sweden and Finland require 117 TWh and 155 TWh of additional capacity by 2045, respectively. Nuclear currently provides 29 percent of Sweden's power and 40 percent of Finland's electricity generation.
The players
Energiforsk
This is a Swedish research institute that facilitates collaborative research on energy and power systems.
EY Sweden
This is a global professional services firm providing consulting and strategy analysis for large-scale industrial sectors.
The details
The report utilized interviews with utility executives, policymakers, and regulators to review nuclear lifetime extensions in Belgium, Canada, France, and the United States. It highlights that 95 percent of U.S. reactors have already secured licenses to operate for 60 years, with most expected to aim for 80 years or longer.
Timeline
June 2026 saw the release of the report on the Nordic electricity system.
The next 10 to 20 years will see many Nordic reactors reaching their planned operational lifespans.
By 2045, Sweden and Finland face critical requirements for additional electricity generation capacity.
The Big Picture
This study follows a pattern set by the U.S. Nuclear Regulatory Commission's license renewal process to extend plant lifespans. It suggests that Nordic energy policy is shifting toward the long-term operational models already being adopted by U.S. nuclear utilities.
Reliable long-term nuclear power generation could stabilize electricity prices for consumers facing rising energy demands. Sustained output from these facilities may prevent grid instability as nations transition toward industrial electrification.
The takeaway
Maintaining current nuclear infrastructure is increasingly viewed as a critical component of regional energy security. Policymakers must reconcile existing reactor lifespans with the accelerating power requirements of the next two decades.
