Alstom is delighted to have been named as preferred bidder by NNB, a subsidiary of EDF Energy UK, for the companys Hinkley Point C nuclear power station in Somerset.

Subject to the signing of a final contract, Alstom expects to supply two 1,750 MW conventional islands, based on ARABELLE steam turbines, together with other non-nuclear construction work. 

At least one third of the project will be UK content. Alstoms UK teams will perform erection of the turbine generators, and undertake service throughout the lifetime of the project.  

The ARABELLE turbines the worlds largest - will be delivered from Alstoms Belfort site in France, whilst other equipment will be delivered from other advanced facilities and suppliers in the UK and in the rest of Europe.  The ARABELLE steam turbine is widely acknowledged as the most advanced in the market, offering outstanding power output (1,000 to 1,900 MW) and efficiency, whether for a boiling water reactor (BWR) or a pressurised water reactor (PWR). 

Around two-thirds of the UKs existing nuclear power stations were built with steam turbines manufactured by Alstom and its predecessor companies, and all of EDFs 58 French reactors use conventional equipment supplied by Alstom. 

Alstom technology currently generates over 50% of the UKs electricity and, every day, around 2,000 Alstom engineers help to maintain and operate the countrys power stations.
