Vattenfall picks Rolls-Royce SMR for new Ringhals reactors

Videberg Kraft has selected Rolls-Royce SMR to supply three planned reactors next to Sweden’s Ringhals nuclear plant, ending a final contest with GE Vernova and moving the project into detailed planning.

The supplier choice is a major milestone for one of Sweden’s most closely watched energy projects. Coverage says the reactors are planned as three 470 MW units, with first output targeted for the mid-2030s and the full buildout expected in the early 2040s.

Supplier choice

The decision follows a three-year assessment that reportedly involved around 70 suppliers before the field narrowed to the final two contenders.

According to the reporting, Rolls-Royce SMR came out ahead of GE Vernova on investment cost, operating cost and build risk. That means the project has now moved from procurement into more detailed technical and commercial planning.

Vattenfall chief executive Anna Borg was quoted in coverage as saying the company had reached the stage where it could choose a supplier. The announcement marks a shift from competition to execution.

What is planned at Ringhals

The reactors are planned for the Ringhals site on Sweden’s west coast, adjacent to the existing nuclear plant. The project envisages small modular reactors rather than a single large unit.

Coverage identifies the planned output as 470 MW for each reactor. If built as described, the plant would add a substantial new source of firm power to Sweden’s electricity system.

One source says Videberg Kraft is owned 60% by the Swedish state and 20% each by Vattenfall and Industrikraft. That ownership structure underlines the political and industrial weight of the project.

Timeline and next steps

The reporting points to first electricity from the new reactors in the mid-2030s, with all three units entering service in the early 2040s. Those dates are still forward-looking milestones, not completed commitments.

Permitting, financing and final investment decisions remain open questions. The supplier choice is important, but it does not remove the need for regulatory approvals and further project decisions before construction can fully proceed.

The next stage is expected to focus on detailed planning for the Ringhals site, including design work, schedule refinement and the remaining approval process. Those steps will determine how quickly the project can move from selection to execution.

Strategic stakes

The decision matters beyond a single power plant. It affects the design, cost, schedule and delivery risk of Sweden’s planned new nuclear build.

It is also a test of Sweden’s long-term electricity supply strategy and of the industrial power needs that are driving new firm generation capacity.

For Rolls-Royce SMR, the win is a significant signal in the European small modular reactor market. The contract strengthens the company’s international rollout at a time when SMR suppliers are competing for early reference projects.

The broader political backdrop remains important. Swedish ministers have framed the nuclear expansion as supportive of jobs and the wider economy, while the project continues to move through a high-profile development phase.

What to watch

The next developments to watch are a formal company statement, additional detail on schedule and financing, and any response from GE Vernova or Swedish ministers.

Further clarity on licensing, ownership arrangements and the pace of site work will show how quickly the Ringhals project can advance after this supplier decision.
