Pre Application Consultation

On 6 December 2019 we launched our pre-application consultation on proposals to remove pylons across the Dwyryd Estuary and place the connection in a tunnel underground. 


We have now submitted our planning application. To view these documents please click here.

We’ve been working closely with local technical stakeholders, including the Snowdonia National Park Authority, Gwynedd Council, Cadw, Natural Resources Wales and the National Trust, as well as landowners and independent landscape consultants, to develop our plans. This has included many detailed ecological and engineering surveys and identifying potential routes for the new underground connection.
