The group has plans to build up to 3.6 gigawatts (GW) of new nuclear capacity in the UK, with work beginning in 2015. This brings total proposals for new nuclear power stations in the UK up to 16 GW.
Commenting on the acquisition, Alistair Phillips-Davies, energy supply director of SSE, said: "Nuclear power is a tried and tested way of generating power that can help meet energy security and climate change objectives, which we support. In line with our commitment to a diverse generation portfolio, we believe that some participation in new nuclear power stations makes sense and complements our core investment in renewable energy."
IIR Europe tipped the GDF Suez consortium as the most likely candidate for the Sellafield site in June when the NDA put the land up for sale.
The consortium lost out earlier this year when it withdrew from the online auction for three sites in Wylfa, North Wales (178 hectares); Oldbury, Gloucestershire (48 hectares); and Bradwell, Essex (200 hectares). That auction exceeded all expectations, raising more than £387 million (US$638.8 million) for the NDA from winning bidders comprised of the UK subsidiaries of RWE AG, E.ON AG and EDF Development Company Limited, a part of Electricite de France SA.
The sale has been welcomed by Energy and Climate Change Secretary Ed Miliband. "These latest plans, together with the ambition of existing plans from two other operators, mean that new nuclear could power the equivalent of all 26 million homes in the UK." he said. "This sale is further proof that we're giving industry the confidence to invest and that the UK is creating a successful low carbon economy."
NDA Commercial Director John Clarke added: "The sale of this land is a significant milestone in our asset-disposal programme and follows on from the successful sale of land at three of our sites earlier this year. The £450 million [US$742.6 million] generated from these sales will be utilized to support the NDA's clean-up mission and is good news for the UK taxpayer."
