Carlisle MP John Stevenson is backing villagers at Cumwhinton who are fighting plans to erect a 328ft wind turbine near their homes.
Bolsterstone Innovative Energy has appealed against Carlisle City Council’s decision to refuse planning consent for a single turbine at Newlands Farm, near junction 42 of the M6.
The firm originally wanted to put three 377ft turbines there.
That scheme was thrown out in 2010, prompting Bolsterstone to table two more applications – one for a single turbine, the other for two.
Both brought more than 1,100 objections and were rejected in November on the grounds that the turbines would be too close to Cringles Farm and Beech Cottage.
Conservative Mr Stevenson said: “I’m 100 per cent behind the objectors.
“I am very disappointed that Bolsterstone have decided to go to appeal.
“I hope the result of that appeal is confirmation of the decision the council made to refuse permission, which was the right decision.”
The appeal is likely to be heard by a planning inspector at Carlisle Civic Centre in late May or June.
News of the appeal has dismayed opponents.
Allison Stamper lives at Cringles Farm, 460 yards from the proposed turbine.
She said: “I am angry and extremely disappointed. These wind energy companies keep coming back and coming back, which is totally unfair.”
Maggie Cleave, who lives 650 yards away, has written to Mr Stevenson.
Her letter says: “It is incomprehensible that this company has come back at our village once again. It has now been nearly four years since the whole process began.
“The last public inquiry took its toll on the stamina and resources of the community. When does ‘No’ really mean ‘No’?”
Villagers raised £25,000 to fight the last attempt.
To date, Bolsterstone has appealed only against refusal of the application for a single turbine but it has not ruled out an appeal against refusal of its plan for two.
