The project has obtained planning approval and has started construction works. It has recently achieved Financial Investment Decision (FID) meaning that all the funding for the full lifespan of the project is now secured and in place guaranteeing the full delivery of this new nuclear power station. When completed, it will provide dependable electricity to 6 million homes for 60 years, which along with renewables, will support Britain to achieve Net Zero by 2050.
