In February 2009, GDF SUEZ and IBERDROLA entered a partnership to participate in the development of new nuclear power stations in the UK.
On 28 October 2009, the joint venture announced that it had been successful in securing an option to purchase land for the development of a new nuclear power station near Sellafield on the West Cumbrian coast from the Nuclear Decommissioning Authority (NDA) for a total cash consideration of £70m.
On 24 June 2011, the UK government confirmed through its National Policy Statement, that NuGen’s site was suitable for a new nuclear power station. NuGen is now preparing detailed plans for developing the site, which will be submitted for consideration by the relevant planning authorities with the aim of a final investment decision being taken around 2015. These plans will be prepared in full consultation with the safety authorities and local stakeholders. On this basis, the expectation is that any new power station would be commissioned around 2023.
On 1 December 2011 NuGen announced that the name Moorside had been selected as the project name.
