UK announces $19 billion investment in first major nuclear plant since the 1990s

Key Points

• UK government to invest £14.2 billion ($19 billion) in Sizewell C, the first new nuclear plant since 1995, aiming to boost energy security and cut reliance on volatile fossil fuel markets.
• Sizewell C is projected to generate enough low-carbon electricity to power 6 million homes and create 10,000 jobs, with operations expected to begin in the 2030s.
• Rolls-Royce was named preferred bidder for developing small modular reactors that could power around 3 million homes and support energy-intensive industries like AI data centers.
• Critics warn that nuclear projects are costlier and slower than renewables and may harm local wildlife, with protests at the Suffolk site and doubts about meeting the UK’s 2030 net-zero target.

LONDON (AP) — Britain will invest 14.2 billion pounds ($19 billion) to build a new nuclear station that will reduce the U.K.'s reliance on volatile international fossil fuel markets, the government said Tuesday.

Officials said the investment will go into building the new Sizewell C nuclear power plant in Suffolk, on England's eastern coast, saying it will generate enough low-carbon electricity to power 6 million homes when it becomes operational in the 2030s.

Prime Minister Keir Starmer said previous governments had dithered and delayed over nuclear power. No new nuclear plant has been opened in the U.K. since Sizewell B in 1995.

“Having our own energy in this country that we control, gives us security, gives us independence, so (Russian President Vladimir) Putin can’t put his boot on our throat," Starmer said. “And it means that we can control the prices in a way that we haven’t been able to in recent years, which has meant very high prices for businesses, for households and for families."

The government also announced that Rolls-Royce is the preferred bidder to develop a number of small modular reactors, which it said can power around 3 million homes and help fuel power-hungry industries like AI data centers.

The Treasury said building Sizewell C will create 10,000 jobs. The investment announced Tuesday is in addition to 3.7 billion pounds the U.K. government already committed to the project.

Nuclear power is seen as an increasingly important electricity source as the government seeks to decarbonize Britain’s electricity grid by 2030, replacing fossil fuels with low-carbon power.

The U.K. also wants to reduce its dependence on imported oil and gas, especially in light of soaring energy prices following Russia’s invasion of Ukraine.

But critics have said nuclear plants are far more expensive and slow to build compared with renewable energy options such as solar and wind power. Environmental groups have also argued Sizewell C will damage local nature reserves that host wildlife like otters and marsh birds.

About 300 people joined a protest against the development at the Suffolk site over the weekend.

“Net zero is supposed to happen by 2030 — there is no way this is going to be completed by then," said Jenny Kirtley, a local resident who chairs the campaign group Together Against Sizewell C.
