388 steel pylons. 27 metres high. Sixty miles through one of the most beautiful and historically significant landscapes in Wales. We are the communities fighting to stop it.

The Land is Our Language

Our Grounded Truth

In Wales, we do not merely live on the land; we are of the land. Our landscape is not a blank canvas for industrial infrastructure — it is the living parchment upon which our history, our folklore, and our language are written.

To plant steel lattice pylons into our valleys is to tear through the very fabric of our Cynefin. When the skyline is scarred, the soul of the community that looks upon it is diminished. We believe that the preservation of our hills, our ridges, and our quiet places is inseparable from the preservation of the Welsh spirit.

Our Promise to the Future

We stand as the current stewards of a beauty that does not belong to us — it belongs to those who came before and those yet to be born.

Our Demand

We do not oppose energy; we oppose the desecration of our home. We call for the undergrounding of all high-voltage lines. We ask that the value of our landscape be measured not in pence per kilometre, but in the priceless continuity of our culture.

“Ni lwybrir ddoe i yfory heb y tir hwn.” Yesterday does not journey to tomorrow without this land

We fully support renewable energy — but we will not accept that its development should come at the cost of our landscape, our heritage, and the communities that call this valley home. There are better options.

Llandovery Community Pylon Action Group

Wales already generates twice the electricity it consumes. This is not a project for Wales. This is a gold rush that will industrialise the beautiful landscapes of rural Wales for profit that flows to Scotland and Denmark.

On the true purpose of the proposal

Our slogan — 'Cofiwch Ddyffryn Tywi' — recognises the parallels between what happened at Tryweryn and what is proposed in the Towy Valley. We are united behind our love of the Welsh countryside and the powerful emotions this invokes.

Remember the Towy Valley
The Threat

What They Want to Build

A 132kV double-circuit overhead line on steel lattice pylons from Nant Mithil Energy Park through the heart of the Towy Valley to Llandyfaelog substation.

Landscape Devastation

27-metre steel pylons slicing through a Special Landscape Area noted by NRW as scenically and ecologically outstanding.

Heritage Under Attack

Iron age hill forts, Roman encampments, Grade I listed Dinefwr and Dryslwyn Castles, Paxton's Tower — centuries of Welsh history.

Communities Broken

Tourism worth £412m to Carmarthenshire. The £19m Towy Valley Path cycle trail. Farming families with generations of roots.

Ecology Destroyed

The River Towy is an SSSI. Home to tree sparrows, Hairstreak butterfly, water voles, otters, Red Kites, and rare orchids.

No Benefit to Wales

Electricity feeds the UK National Grid, not Wales. Bute Energy is based in Scotland, financed by Danish investors. Profits leave.

Health Risks Ignored

IARC classifies power-frequency magnetic fields as "possibly carcinogenic." The route passes near homes, schools, and nurseries.

The Reality

Pylons This High Every 250m

A 27-metre crane erected in the valley to show the true scale of just one pylon. Imagine 388 of them stretching for sixty miles.

The Solution

Underground, Not Overhead

Welsh Government's preferred position: where possible, cables should be laid underground. The technology exists. It works.

Cable Ploughing Technology

The cable plough cuts, installs and back-fills in one operation. It works on almost any terrain, manoeuvres around rocks, trees, hedges and walls. The land is reinstated the same day.

Proven at Scale

Local specialist ATP demonstrated burying both 132kV and 400kV cables after one of the wettest winters on record. Pylons are being removed in Snowdonia and Dorset. If they can, so can we.
