The financing model for new nuclear power in Sweden consists of three main parts: state loans, price guarantee agreements, and a risk- and profit-sharing mechanism, according to multiple reports. For state loans, companies need to contribute only a smaller portion of the cost with their own capital and can borrow the rest from the state, with 220 billion kronor budgeted for these loans and an equal amount set aside as a safety margin. The price guarantee agreement ensures a price per produced kilowatt-hour; if the market price falls below the guaranteed price, the state covers the difference, valid for up to 40 years, with the price guarantee estimated to cost 1-3 billion kronor per year, or over 100 billion kronor for the 40-year period. The risk- and profit-sharing mechanism is activated if needed based on a market valuation of the project company two years after operation start, adjusting interest rates on state loans or the guaranteed electricity price, providing additional flexibility for long-term projects.
Sweden's nuclear policy has evolved significantly in recent years, with the incoming centre-right coalition government adopting a positive stance towards nuclear energy in October 2022, according to reports. In November 2023, the government unveiled a roadmap envisaging construction of new nuclear generating capacity equivalent to at least two large-scale reactors by 2035, with up to 10 new large-scale reactors coming online by 2045. In May this year, Sweden's parliament approved government proposals for providing state aid to companies investing in new nuclear reactors, with state aid loans limited to the equivalent of four large-scale reactors, about 5000 MWe of capacity. Support may only be granted if new reactors are located at the same location and have a total installed output of at least 300 MWe, and two-way Contracts for Difference may be entered into once a new reactor has become operational and been licensed to produce electricity at full capacity. The new act on state aid entered into force on 1 August, since when interested companies have been able to apply for aid, marking a formal opening for project submissions.
The government is now taking concrete actions to implement these policies, having launched a fast-track inquiry into how the state can facilitate the construction of new nuclear power. The government has proposed that the 2026 budget bill include financial frameworks for negotiating with companies applying for support, with these frameworks involving powers to enter into agreements and decide on loans for investments in new nuclear power and on price hedging agreements. These frameworks are based on expected lending of SEK220 billion (USD23.4 billion) over 12 years for reactor construction and expected future annual expenses for price hedging of SEK1-3 billion per year for 40 years after reactors are operational. The government said exact terms will be negotiated individually with each project company based on project conditions, and noted that to provide support to a company, approval from the European Commission is needed, which may lead to further adjustments to agreements. State costs are affected by final reactor construction costs and future electricity price development, according to the government, which emphasized that the proposal for financial frameworks does not constitute a price tag but an upper limit for negotiations.
State ownership and project developments are advancing at the Ringhals nuclear site, where the state is forced to become the majority owner, holding 60% in the new nuclear power company Videberg Kraft, which will build new, smaller reactors at Ringhals, according to multiple reports. Last month, Vattenfall decided to choose small modular reactors for new nuclear capacity at the existing Ringhals plant site, with a shortlist of two technologies: GE Vernova Hitachi's BWRX-300 and the Rolls-Royce SMR. Vattenfall said an application to the government for state risk-sharing was to be submitted and a final supplier selected, indicating active planning despite uncertainties about the exact ownership structure and project timeline.
The first applications under new regulations are emerging, with Kärnfull Next submitting Sweden's first application under the new Act on Government Approval of Nuclear Facilities. This application covers a planned small modular reactor campus in Valdemarsvik, southern Sweden, and has been formally submitted to Johan Britz, Minister for Employment and acting Minister for Climate and the Environment. Locations such as Valdemarsvik, Motala, Västervik, Nyköping, and Karlshamn are being evaluated as potential sites in the Re:Firm South program, showing broader geographic interest in small modular reactor deployment.
Industry expansion is underway, with Studsvik's acquisition expanding its role from supporting existing nuclear fleets into developing new nuclear projects, reflecting growing corporate investment in the sector. This move aligns with increased activity across Sweden's nuclear industry as companies position themselves for new construction opportunities under the government's supportive policies.
Industry reactions have been positive, with the Swedish government's proposal for a national risk-sharing model for investments in new nuclear power described as a historic and welcome step toward realizing fossil-free electricity production. For Kärnfull Next, the government proposal confirms growing momentum behind SMRs and enables progress in the Re:Firm South program, according to multiple reports. Christian Sjölander, CEO of Kärnfull Next, stated in a press release that the government proposal sends a clear signal to investors, municipalities, and technology providers that the state is ready to share risks and enable long-term infrastructure projects, and that for planned SMR initiatives, they can now take the next step in discussions with partners to move the process forward, with an application dialogue expected later this year.
A critical context for Sweden's nuclear expansion is the requirement for European Commission approval of state aid, which the government noted may lead to further adjustments to agreements. The Commission's review process will assess whether the support complies with EU competition rules, potentially influencing the final terms and timing of projects. This regulatory layer adds complexity to Sweden's ambitious nuclear plans, as outcomes remain pending.
The implications of Sweden's nuclear financing model include significant long-term financial exposure for the state, with price guarantees extending up to 40 years and loans totaling hundreds of billions of kronor. Market price risks are substantial, as the state covers differences if electricity prices fall below guaranteed levels, potentially costing over 100 billion kronor over the guarantee period. These commitments represent a major fiscal undertaking that will shape Sweden's energy and budgetary landscape for decades.
Several unknowns persist, including which specific companies have applied for state aid under the new act as of now, and what the exact terms and conditions for the state loans and price guarantee agreements being negotiated with individual project companies will be. The government's fast-track inquiry into facilitating new nuclear construction has not yet been completed, leaving its specific recommendations and timeline uncertain. Additionally, how many small modular reactors are planned for the Ringhals site and what the expected timeline for construction and operation is remains unclear, as does the current status of the European Commission's approval process for Sweden's state aid to new nuclear projects.
