Sweden just made its biggest bet on nuclear power since the late 1970s. State-owned utility Vattenfall has selected Rolls-Royce SMR to deliver three small modular reactors for a new facility on the Värö Peninsula, collectively generating approximately 1,500 MW of capacity.
That’s enough juice to power roughly one million homes.
How Sweden picked its reactor partner
This wasn’t a snap decision. Vattenfall’s search started with a pool of 75 potential suppliers, a number that was gradually whittled down through a formal evaluation process. By August 2025, only two contenders remained: Rolls-Royce SMR and GE Vernova Hitachi.
Large-reactor designs were excluded entirely from consideration. Each Rolls-Royce SMR unit is rated between 470 and 500 MWe. The light-water reactor design offers advantages in standardization and construction efficiency.
