Sweden has taken one of its most significant energy policy decisions in decades, moving forward with a financing agreement for the construction of a new generation of nuclear reactors. The deal, announced by Prime Minister Ulf Kristersson, marks a major milestone in the country’s strategy to strengthen energy security while supporting its long-term climate ambitions.
The agreement establishes the first state-backed financing package for Videberg Kraft, the company leading the project. Under the new ownership structure, the Swedish government will become the majority shareholder with a 60% stake, while state-owned energy company Vattenfall will reduce its participation from 80% to 20%. Another 20% will remain in the hands of an industrial consortium. The package must still receive approval from the European Commission under EU state-aid rules before it can enter into force. The investment represents a dramatic shift in Sweden‘s energy policy. If completed, these will be the first nuclear reactors built in Sweden in more than forty years, reversing decades of limited investment in new nuclear capacity.
A New Era for Swedish Energy
Sweden already relies on a low-carbon electricity system dominated by hydropower and existing nuclear plants. However, rapidly increasing electricity demand—driven by industrial electrification, battery manufacturing, hydrogen production and the expansion of data centres—has convinced policymakers that additional stable, fossil-free power generation is essential. The current government has therefore made nuclear energy a cornerstone of its long-term energy strategy. Parliament has already approved legislation designed to facilitate new nuclear investments, including financial support mechanisms and the removal of previous restrictions on reactor construction. The national objective is to build two large-scale reactors by 2035 and the equivalent of ten new reactors by 2045, including Small Modular Reactors (SMRs).
Small Modular Reactors at the Heart of the Plan
Earlier this month, Videberg Kraft selected Rolls-Royce SMR as its preferred technology partner to develop three Small Modular Reactors at the Ringhals nuclear site on Sweden’s west coast. Together, the reactors are expected to provide around 1,500 MW of generating capacity—enough to produce roughly 12 TWh of electricity annually, equivalent to about six percent of Sweden‘s current electricity consumption. Unlike traditional nuclear plants, SMRs are designed to be manufactured in modules before assembly on site, potentially reducing construction times, costs and financial risks while improving scalability.
Balancing Climate Goals and Energy Security
The Swedish government argues that expanding nuclear power is necessary to guarantee reliable electricity supplies while maintaining one of Europe’s lowest-carbon power systems. Officials also see new nuclear capacity as a key factor in preserving Sweden’s industrial competitiveness and achieving the country’s target of net-zero greenhouse gas emissions by 2045. Supporters believe the investment will strengthen energy independence and provide stable baseload electricity alongside renewable sources such as wind and hydropower. Critics, however, continue to question the project’s cost, construction timeline and financial risks, arguing that large public investments could instead be directed toward renewable energy, storage technologies and grid expansion.
A Project That Could Shape Europe’s Nuclear Revival
Sweden’s decision is being closely watched across Europe. As many countries reconsider the role of nuclear power in achieving climate neutrality while ensuring secure electricity supplies, Stockholm’s financing model could become a reference for future public-private nuclear partnerships. Should the European Commission approve the package, Sweden will formally begin its first new nuclear construction programme since the 1980s—opening a new chapter in the country’s energy history.
