SGE SA, a developer of small nuclear plants backed by Polish billionaire Michal Solowow, is planning a £35 billion ($46 billion) fleet in the UK with the first units expected to start up in 2034. 

The company submitted an application under the UK’s Advanced Nuclear Framework to build 14 units at three sites to provide enough power to serve nearly 8 million homes for decades, SGE said in a statement Thursday.

The installations will use GE Vernova Hitachi BWRX-300 small modular reactors. Google Cloud and Samsung C&T are among the members of the deployment team.  

SGE expects the project to enter the Advanced Nuclear Pipeline in November with site selection and government negotiations to be completed in the first half of 2027. Together, the reactors would be able to produce 4.2 gigawatts, the equivalent of more than 10% of the country’s electricity. 

The project would help jumpstart the UK nuclear sector and expand supplies of zero-carbon energy. The country’s grid is struggling with capacity constraints and high energy bills, delaying the ability to connect data centers.
