Vattenfall selects Rolls-Royce SMR over GE Vernova for three reactors at Ringhals, adding 1,500 MW of clean nuclear power to Sweden's grid by the mid-2030s.
- Videberg Kraft chose three Rolls-Royce SMR units totaling ~1,500 MW, defeating GE Vernova's rival five-reactor BWRX-300 proposal.
- Rolls-Royce shares rose 3.85% to 1,358.40p in London; the contract is described as worth several billion pounds.
- Sweden's government plans a 60% majority stake in Videberg Kraft with up to SEK 34.3 billion in construction-period financing.
Lead
Videberg Kraft, the nuclear development company 80% owned by Vattenfall, on Monday selected Rolls-Royce SMR as supplier for three small modular reactors at the Ringhals site on Sweden's southwest coast — the country's first confirmed step toward new nuclear power in more than four decades and the British technology's third consecutive win in a European competitive tender.What Happened
The selection, announced June 15, 2026, ends a multi-year competitive process in which Rolls-Royce SMR defeated GE Vernova's BWRX-300 boiling water reactor design — a five-unit proposal — for the project formally known as the Videberg venture on the Värö Peninsula in Varberg Municipality.
Each Rolls-Royce SMR unit delivers 470 megawatts of electrical output. Three units combined will add approximately 1,500 MW of baseload generating capacity and produce roughly 12 terawatt hours annually — about 6% of Sweden's total electricity consumption. The first reactor is targeted for commercial operation in the mid-2030s, contingent on permitting and regulatory approvals.
Vattenfall Chief Executive Anna Borg said the project "will now be turned into reality." Swedish Energy Minister Ebba Busch said the agreement would "result in lower electricity prices for consumers." UK Prime Minister Keir Starmer called it "a major win for Britain's economy."
Market Reaction
Rolls-Royce Holdings (RR.L / RYCEY) shares gained 3.85% to 1,358.40p in London, reaching levels last seen in March. CEO Tufan Erginbilgic said the Vattenfall selection "reinforces the status of Rolls-Royce SMR as the only company with multiple contractual commitments to deliver SMR units in Europe" — a reference to prior wins with Great British Energy Nuclear in the United Kingdom and CEZ Group in the Czech Republic. GE Vernova (GEV) had competed with its BWRX-300 design under a five-reactor configuration that would have delivered comparable combined output. The Swedish decision closes this market to that platform for the current build cycle.Strategic Context
Sweden's Riksdag passed legislation in 2025 enabling state-backed financing for new nuclear power Sweden through a combination of government loans and Contracts for Difference, replicating a model used successfully in the United Kingdom. The Swedish government now plans to acquire a 60% majority ownership stake in Videberg Kraft through an initial SEK 1.8 billion capital injection, with parliamentary authority sought for up to SEK 34.3 billion in construction-period funding.
The Videberg Project is built around proven pressurized water reactor (PWR) technology — the same class as the existing Ringhals units — reducing regulatory novelty and engineering risk. Ringhals currently operates two PWR units following the politically driven decommissioning of its two older units under a prior phase-out policy that Sweden has since reversed.
Clean Energy Tech Dimension
Sweden's return to nuclear power reflects energy security pressures that sharpened after 2022. The country depends heavily on hydropower and cross-border power trade; rising demand from steel, battery gigafactories, and data center investments requires firm baseload additions to meet net-zero targets by 2045 without grid instability.
The Rolls-Royce SMR's industrialized manufacturing model — factory-built modular components assembled on-site — is central to its competitive case. The approach is designed to compress construction timelines and reduce per-unit capital exposure compared with conventional large-scale nuclear plants, offering a scalable pathway for utilities facing long permitting cycles and capital constraints. This clean energy tech proposition has now been validated in three separate national procurement processes within two years.
Outlook
With contractual commitments spanning the UK, Czech Republic, and now Sweden, Rolls-Royce SMR holds a clear European first-mover position in utility-scale small modular reactor deployment. Remaining milestones for the Videberg Project include formal site permitting applications, Riksdag ratification of the government's ownership and financing commitments, and finalization of CfD contract terms. The mid-2030s operations target assumes no material regulatory delay. At SEK 34.3 billion in state construction support alone, nuclear power Sweden has moved decisively from policy ambition to committed sovereign capital.
