British Energy
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, but on 4 February 2013, Centrica stated it would withdraw from the project.
