Last Chance to See…
Plynlimon was the first proper hill that I climbed on my own. It’s also the first hill I camped on. My first visit was in near-zero visibility, and the sense of achievement compensated for the total lack of summit views. I’ve been back a lot since then, and it’s an area I love. It’s the feeling of space, the silence, and the sense of being in wilderness.
Except it’s not. There are signs of man everywhere. Some, millennia old, like the bronze age burial cairns that sit atop most of the peaks here. Others, mere centuries old, like the remains of the Lead Mine on the track from Eisteddfa Gurig, and Sir Watkin Williams-Wynn’s boundary markers.
And there are newer intrusions, like the Nant-y-Moch reservoir and the useful navigational handrails of sheep fences.
But as you reach the lead mine, take the time to turn and look behind you. Across the road, you’ll see some of the Cefn Croes wind turbines peeping over the hillside. The 39 turbines here were installed in 2005, despite vociferous opposition.
Now there are plans for a new and bigger wind farm on the hills south and west of the reservoir. 64 turbines, up to 145m high, and significantly closer than Cefn Croes.
Both sides of the wind energy debate seem to be able to produce reams of misleading figures, maps and other propaganda, but it all boils down to emotion or money at the end. And yet… the environment and landscape here will be changed significantly, permanently, and for the worse – more by the concrete foundations and access roads than by the turbines perched on top. The Cefn Croes turbine bases required over 600 tons of concrete each. These ones won’t be smaller. And the concrete here is permanent. It will not be removed when the wind farm is decommissioned.
Looking at the remains of the lead mine, we don’t have a good record in this country of clearing up industrial sites in the hills when they become economically unviable – and wind turbines don’t last forever. Nant-y-moch has a planned lifespan of only 25 years. If we do have to tolerate wind farms in our hills, how do we ensure that we’re not left with a forest of fallen, rusting turbines in a concrete desert in a hundred or so years time?
