Nuclear power in Sweden

The electricity sector in Sweden has three operational nuclear power plants with 6 operational nuclear reactors, which produce about 29.8% of the country's electricity. The nation's largest power station, Forsmark Nuclear Power Plant, has three reactors producing 3.3 GW and 14% of Sweden's electricity.

Sweden formerly had a nuclear phase-out policy, aiming to end nuclear power generation in Sweden by 2010. On 5 February 2009, the Government of Sweden announced an agreement allowing for the replacement of existing reactors, effectively ending the phase-out policy.

In June 2023, the new Kristersson Cabinet established after the country's 2022 election voted to switch the national energy target from 100% renewable electricity by 2045 to 100% fossil fuel-free electricity by 2045, a move seen as supporting and extending the ongoing use of nuclear power in the country. At the time, hydro, nuclear, and wind power already produced 98% of Sweden's electricity, with the government aiming to increase electricity production from carbon-free sources to meet an estimated doubling of national electricity consumption by 2040.
