People wanting to prevent plans which could see hundreds of pylons being built across Shropshire and Mid Wales are being urged to write and fight.
Montgomeryshire Against Pylons has been formed to combat plans to build a substation in Mid Wales and a 400,000 volt cable linking it to the National Grid.
The group is now hoping to get as many people to write to various organisations including the Countryside Council for Wales and Cadw, which protects heritage sites, in a bid to protest against the plans.
Jonathan Wilkinson, chairman of MAP said the group needed people to “write and fight” and sign petitions.
He said: “We have left the Welsh Assembly with little doubt as to exactly how strongly we, the people of Montgomeryshire and its surrounding areas, feel regarding the impact of the proposed windfarms, hubs and pylons that are being so forced on Mid-Wales.
“We want people to join our campaign to stop the turbines and the related infrastructure from destroying Montgomeryshire and the surrounding areas. Proposed plans would see the heartland of the county disappear under concrete and massive wind turbines, as high as the London Eye, together with supporting 400,000 volt cables.
“We need help in turning National Grids pylons away from the valleys of Montgomeryshire, Mid Wales and beyond and stop the wind farms from desecrating the land.”
He also urged people to write to the Royal Society for the Protection of Birds.
He said: “Curlews nest in great numbers in Montgomeryshire. Peregrine falcons have nested on the hills above the valley for 20 years and the valley is their hunting ground. Both species are on the red list of endangered birds and we encourage people to write to the RSPB to express their thoughts.”
He said addresses for organisations and bodies to write to had been included on the Montgomeryshire Against Pylons website www.montgomeryshireagainstpylons.org
It comes weeks after National Grid bosses announced they would be holding consultation events across the region to find a potential route for a 400,000 volt cable, using either 46-metre high pylons or by routing the wires underground. They said no decision had yet been made.
