Sweden passes bill on state aid for new reactors

In October 2022, Sweden's incoming centre-right coalition government adopted a positive stance towards nuclear energy. In November 2023, it unveiled a roadmap which envisages the 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 a bill submitted to parliament on 27 March this year, the Swedish government proposed a new law regarding state support for nuclear power investments. In the bill it proposed providing state loans to finance new reactors as well as a contract-for-difference power price mechanism.

The loans - aimed at lowering the cost of financing new nuclear - will be limited to the equivalent of four large-scale reactors (about 5000 MWe of capacity). The government noted that support may only be granted if the new reactors are located at the same location and have a total installed output of at least 300 MWe. The two-way Contracts for Difference may be entered into once a new reactor has become operational and has been licensed to produce electricity at full capacity.

The Riksdag has now approved the government's proposal. The new act on state aid enters into force on 1 August. Interested companies may apply for the aid from that date.

"This is a historic announcement that takes responsibility for public financing and tax payers' money when we enable actors to build new nuclear energy," said Minister for Financial Markets Niklas Wykman. "An expansion of nuclear power is expected to result in greater price stability and lower system costs, which helps households as well as businesses. With new nuclear reactors, we are paving the way for higher growth, more jobs and better conditions to achieve the climate transition."

The government appointed Mats Dillén in December 2023 to produce and submit proposals for models for financing and risk sharing for the construction of new nuclear power reactors. According to the mandate, the proposed models must be designed so that nuclear power with a total output of at least 2500 MWe - equivalent to the output of two large-scale reactors - must be in place by 2035 at the latest.

Dillén presented the findings of the study in August last year. His report said the investigation "identified conditions which give rise to a discrepancy between a private investor's business case for new nuclear power and the socioeconomic equivalent. It is concluded that efficiency reasons give a rationale for the state to support investments in nuclear power".

His proposed financing and risk sharing model consists of three main components that lead to a lower cost of capital that facilitates new investments in nuclear power at a low cost. The components are: state loans to finance investments in new nuclear power, which lowers the cost of capital; a two-way contract-for-difference signed between the state and the nuclear power producer; and a risk and gain-share mechanism that gives investors a minimum return on equity.
