In January 2019, work was suspended on the development of the Wylfa Newydd nuclear power station on Anglesey. In this report, we consider the implications of the suspension, and what might be done to restart development.

Implications for North Wales

North Wales is a key centre for the nuclear sector. Wylfa Newydd was a key part of the North Wales Growth Deal, a new agreement to boost the region's development. We heard it was important for the North Wales economy that other projects from the Growth Deal were brought forward to fill the gap left by Wylfa Newydd.

Our main findings and recommendations to the Government are:

  • the UK Government, Welsh Government, local authorities and other partners should work together to ensure that other projects in the Growth Deal bid can be accelerated to minimise the damage to the local economy.
  • the two Governments should support Growth Deal partners on new high quality projects, in time for the 2019 Budget.
  • the UK Government should work with the Welsh Government and developers on a proposal for a small modular reactor at Trawsfynydd.
  • the UK Government should talk to the Nuclear Decommissioning Authority about opportunities for the apprentices from Wylfa Newydd.

Resuming work

We heard that Wylfa Newydd was one of the best sites in the country for nuclear development, not least because of the geology and supply of cooling water. It was suggested that Hitachi, the owners of the site were concerned about the financing arrangements, and that a new model might help to get development back underway. We were told that another option might be for Hitachi to sell the site to another developer.

Our main findings and recommendations to the Government are:

  • the UK Government should complete its assessment of the regulated asset base model as soon as it can. If the model is viable, the legislation to enable it should be introduced without delay.
  • if, after this, Hitachi does not want to resume development, the UK Government should encourage it to sell the site. The UK Government should also seek out other developers who might wish to take work forward.
