What is the total investment value and scope of SGE SA's planned UK nuclear fleet, including number of units, sites, and expected power output?

SGE SA is planning a £35 billion ($46 billion) nuclear fleet in the UK, comprising 14 small modular reactors (SMRs) to be deployed across three sites. The project aims to generate 4.2 gigawatts of electricity—enough to serve nearly 8 million homes for decades—and represents over 10% of the UK’s current electricity supply. The reactors will use GE Vernova Hitachi BWRX-300 technology, and the first units are scheduled to start up in 2034.

What regulatory process is SGE SA following in the UK, and what are the key upcoming milestones for the project?

SGE SA has submitted an application under the UK’s Advanced Nuclear Framework and expects to enter the Advanced Nuclear Pipeline in November. Key upcoming milestones include completing site selection and government negotiations in the first half of 2027. The company’s deployment team includes Google Cloud and Samsung C&T, supporting the development of the 14-unit fleet.
