Horizon Nuclear Power has recently announced their decision to suspend their UK nuclear projects.  They have told us that they no longer need our connection for Wylfa Newydd and have brought our contract with them to a close. 

In light of this we have withdrawn our application for a new electricity connection across Anglesey and North Gwynedd.

We would like to thank the thousands of local people and organisations who have engaged with us on the project.  During eight years of detailed work, we have considered over 5,000 pieces of feedback, hosted 70 consultation events and undertaken thousands of assessments which resulted in hundreds of changes to our proposals. 

We are writing to landowners who may have signed agreements with us to explain what this decision means for them.

If Horizon or another developer brings forward plans for new nuclear development at Wylfa, we will work closely with them to ensure that there’s a strong and secure electrical connection.  As always, local communities would be able to have their say on any future proposals.
