EDF Energy came into being in 2003, following a series of acquisitions and mergers:
- London Electricity – merged in January 1999
- SWEB supply business – merged in July 1999
- Sutton Bridge power station – acquired in March 2000
- Cottam power station – acquired in November 2000
- West Burton power station – acquired in December 2001
- EPN Distribution – merged in January 2002
- SEEBoard – merged in July 2002.
Since then the company has grown steadily, aiming to become more responsive and effective in the fast-changing energy marketplace by integrating and streamlining operations.
Early in 2009, EDF Energy acquired British Energy. The combined business is one of the UK’s largest energy companies, and its largest producer of electricity. In its nuclear activities, EDF Energy has partnered with energy company Centrica, which has a 20% stake in the company's eight existing nuclear power stations.
In November 2010, EDF Energy divested itself of EDF Energy Networks, the part of the business that owned and operated the cables and power lines that distribute electricity around London, the South East and the East of England.
Ownership and governance
EDF Energy is a wholly owned subsidiary of EDF, one of Europe’s largest energy groups. As such, EDF Energy is not listed on the London Stock Exchange – but the company’s own corporate governance standards seek to embrace many of the same principles as those required of companies listed on the Exchange.
