Plaid Cymru politicians have highlighted concerns in the Senedd regarding a proposed network of pylons along the Tywi Valley.

Renewable energy developer Bute Energy recently wrote to local landowners in the Tywi Valley outlining proposals for a new 60-mile 132Kv electricity connection from Nant Mithil Energy Park located east of Llandrindod Wells, Powys, to the existing electricity network between Carmarthen and Pont Abraham.

The proposals have caused widespread concern in the Tywi Valley, with more than 70 residents attending a recent meeting held at Llanarthne.

Particular concerns have been raised regarding the potential visual impact of 20-metre-high pylons; many local residents and politicians want to see the proposed electricity connection undergrounded along the valley – causing less visual pollution.

Speaking in the Senedd on Wednesday, February 8, Cefin Campbell, Plaid Cymru Member for Mid & West Wales highlighted the concerns with the Welsh Government’s Climate Change Minister, Julie James MS.

He went on to call on the Welsh Government to strengthen measures and expectations that would encourage the undergrounding of electricity cables in proposed grid connection developments.

Speaking after his question, Cefin Campbell MS said: “There has rightly been widespread concern locally regarding the possible erection of pylons along the Tywi Valley.

"Like others, I believe the undergrounding of these cables would be a rational compromise – allowing the furthering of our grid capacity, whilst also minimising the long-term scarring of the landscape."

Adam Price, MS for Carmarthen East & Dinefwr, added: “Over recent weeks my inbox has been inundated with concerns regarding the proposals which could see pylons erected along the beautiful Tywi Valley – with many alarmed as to the visual detriment to the natural and historic beauty of the area.

“I welcomed the opportunity to meet with Bute Energy last month to discuss their proposals further, and I will continue to press to ensure that the concerns of the local community are fully considered in the proposals.”

Bute Energy has previously stated it is engaging with landowners to help develop a detailed and accurate assessment of potential routes.

It will be holding further public consultation later this year, before submitting a planning application.
