Four new nuclear reactors could be created in Britain if EDF's proposed acquisition proves to be successful.
Prime minister Gordon Brown said that the deal was "good value for the taxpayer" and a "significant step" towards the creation of new power stations.
"Nuclear is clean, secure and affordable; its expansion is crucial for Britain's long term energy security, as we reduce our oil dependence and move towards a low carbon future."
EDF recently claimed that the deal would help to secure "affordable energy" for both its domestic and commercial consumers.
The company added that it would also improve its capabilities in field such as nuclear engineering, safety management, design, construction and operations.
