New system cost study on the development of Swedish nuclear power

The study shows that Sweden has favourable conditions to reach net-zero emissions by 2050 in a cost-effective way. It highlights the interplay between nuclear power and onshore wind power as key, where system stability is achieved through a broad mix of fossil-free technologies.

"To achieve net zero, we cannot pit different power sources against each other. It is about how fossil-free technologies can best work together to create a robust and cost-effective system. The NEA study emphasises that a combination of lifetime extensions of existing nuclear power, new nuclear power and continued expansion of wind power enables Sweden to maintain its competitiveness and enjoy low electricity prices, even as electricity demand increases significantly," says Gustav Ebenå, Head of the System Analysis and Statistics Department at the Swedish Energy Agency.

The study is based on electricity use in the Swedish Energy Agency's long-term scenarios and has been modelled by experts at the NEA.

"Our scenarios are used to explore alternatives and prepare for different outcomes, and to understand the consequences of various possible futures. The NEA study on potential development pathways for nuclear power can complement our regular work of developing future scenarios for the energy system as a whole," says Martin Johansson, Head of the Forecasts and Scenarios Unit at the Swedish Energy Agency.

Nuclear Energy Agency (NEA)

The OECD Nuclear Energy Agency (NEA) is a cooperative organisation for countries with advanced nuclear technology infrastructure. The organisation's objective is to support member countries in maintaining and further developing the scientific, technical and legal foundations required for the safe, environmentally sustainable and economically viable use of nuclear energy for peaceful purposes.

The NEA was founded on 1 February 1958 and Sweden has been a member since the beginning.
