YNYS Môn Assembly Member Rhun ap Iorwerth sparked a debate over an act which could have a bearing on the development of the electricity infrastructure on Anglesey.

He quizzed the Welsh Government about the role of the 'Well-Being of Future Generations Act and said the connection plan for the island should only happen in accordance with the principles of the act.

The act was brought in in 2015 to help improve the social, economic, environmental and cultural well-being of Wales.

Speaking in Cardiff, the AM said: “The National Grid intends to have a new electricity connection across Anglesey with the cost being the main, if not the only, factor in deciding what kind of connection that will be," he said.

"What they intend to do, therefore, is to go for the cheapest possible option, pylons above ground rather than undergrounding, or placing cables underwater, which is what we on Anglesey would want to see.

"Going underwater or underground would safeguard the interests of Ynys Môn now and for future generations, and we do have a Well-being of Future Generations (Wales) Act 2015, here in Wales.

Addressing his comments to Cabinet Secretary Mark Drakeford, he said:

“You're the Cabinet Secretary with responsibility for the implementation of that act. Are you willing to give a commitment that you will work with me and others such as campaigners against pylons to urge the National Grid, Ofgem and the UK Government to ensure that this connection plan can only happen in accordance with the principles of this important piece of legislation?"

The Cabinet Secretary replied: “We as a Government are working more closely with the local councils on the issues.

“There is some recognition there by the National Grid of the impact of the act. I hear, of course, what the Member says about under grounding and over grounding and the Welsh Government's starting position is that under grounding is the preferred option, but there will be discussions as we seek to maximise the benefits for the island while mitigating the impacts of these developments.”

Speaking afterwards Mr ap Iorwerth added: “I will be meeting National Grid in to discuss this matter further. Even though the act is not binding on them, it is important that the principles of the Act are respected.”
