Nuclear New Build Generation Company (NNB GenCo) is a subsidiary created by EDF Energy to build and then operate two new nuclear power stations in the United Kingdom. The new plants are to be Hinkley Point C and Sizewell C and will eventually produce up to 6.4GW in total.[1]

EDF originally entered the UK nuclear industry with the acquisition of British Energy in 2009. At the same time, EDF established NNB GenCo as a separate subsidiary for the construction of additional new nuclear plants. Centrica purchased a 20% stake in British Energy from EDF, and also had an option to acquire 20% of NNB GenCo,[2] but on 4 February 2013, Centrica stated it would withdraw from the project.[3]

The company's plans include building four new nuclear reactors adjacent to existing plants, two at Hinkley Point C in Somerset and two at Sizewell C in Suffolk. Framatome's (previously Areva) European Pressurized Reactor is the preferred design for the sites.[4]
