About Us

Horizon Nuclear Power is a UK energy company developing a new generation of nuclear power stations to help meet the country’s need for stable and sustainable low carbon energy. With headquarters in Gloucestershire and a site office on Anglesey, the company is a wholly owned subsidiary of Hitachi, Ltd. We are currently planning to deliver at least 5,400MW of electricity, enough power for around 10 million homes.

Nuclear power can play a vital role in meeting the challenge of maintaining affordable and secure energy supplies for the UK, while also tackling the global threat of climate change. This is why we are developing the next generation of nuclear power stations for the UK.
These new nuclear power stations will help Britain hit emissions reduction targets and create thousands of new jobs for UK companies. Each power station could create up to 850 permanent jobs, with a construction workforce of around 4,000 workers for the majority of the time, potentially reaching between 8,000 and 10,000 workers during peak periods, at both Wylfa Newydd on Anglesey and then at Oldbury, South Gloucestershire.
Together with national, regional and local government, as well as sector bodies, colleges and universities, we are working to ensure that people and businesses in local communities are well placed to take advantage of new jobs and supply contracts.
