National Grid has launched the first stage of public consultation on proposals for the Western Link 2 electricity connection between Scotland and Wales.
The company said the project forms part of Uwchraddio’r Grid / The Great Grid Upgrade and would help carry more renewable electricity to homes and businesses across Wales.
National Grid added that the link would be capable of carrying up to 2GW of electricity in either direction, enough to power around two million homes.
Western Link 2 is a joint proposal by National Grid and Scottish Power Energy Networks for a predominantly subsea high-voltage direct current electricity link between Scotland and Wales.
In North Wales, the proposals include about 260km of offshore cable to a landfall at Caernarfon Bay, about 25km of underground cable, a new converter station near Pentir and works to extend the existing Pentir substation.
National Grid said the project would support a multi-billion-pound supply chain and create skilled jobs in North Wales.
The first stage of consultation runs from 23 June to 21 July 2026.
Leandro Vacirca, project director at National Grid, said: “Western Link 2 will play an important role in delivering the electricity infrastructure Wales needs for a secure and more efficient energy future.”
“As demand grows, it is essential we make better use of renewable energy sources by upgrading the electricity network so that clean energy isn’t wasted.”
“We are seeking feedback on early-stage proposals which will give communities and stakeholders the opportunity to influence our plans.”
“Local knowledge is important in the development of Western Link 2 and will help us minimise impacts wherever possible.”
“We also want local communities to benefit from the transition to cleaner, renewable energy through local jobs, skills and supply chain opportunities.”
