Development of Sizewell C took a huge step forward today as the companies were announced that will build its sister nuclear power station in Somerset.

Construction of the new twin reactor on Suffolk's coast has always hinged on the successful development of Hinkley Point C, which will be the UK's first new nuclear plant in more than 20 years.

Today French firm EDF Energy announced a number of national and Somerset companies or joint ventures as preferred bidders set to win contracts worth more than £1.3 billion at Hinkley.

The firms include engineering giants Balfour Beatty, Doosan Babcock, Laing O'Rourke and Weir, and companies close to the Somerset site such as food producers Somerset Larder and bus organisation Somerset Passenger Solutions.

It is now estimated that more than 60% of the construction cost will be placed with UK firms, 3% more than an initial estimate.

The power station will provide 25,000 jobs during the construction phase, including 1,000 apprenticeships.

A final investment decision (FID) is expected in the coming months, after which the contracts will be signed.

Hinkley Point C will cost around £14bn to build at present costs, rising to £24bn by the time it is finished, and interest payments have been added.

Background preparatory work has been taking place for Sizewell C but further progress has been delayed while the final investment decision is put in place for Hinkley.

Now that decision is fast approaching, people in east Suffolk will soon be asked to take part in further consultation on a number of major issues, including road improvements such as the Four Villages Bypass project, the sites for park and ride services to ferry workers to and from the site, and an accommodation village for workers.
