A wind turbine burst into flames, shutting a rural road for hours.
The blaze at the 25-turbine Tir Mostyn and Foel Goch windfarm in Nantglyn, Denbighshire, lasted for about two hours.
Debris left behind by the fire forced North Wales Police to close Drws-y-Buddel, between the site and Pentrellyncymer Outdoor Education Centre.
Tir Mostyn is capable of annually lighting up to 15,500 properties, but all 25 turbines were shut down for safety reasons yesterday.
The fire broke out at about 6pm on Tuesday but no precise cause has been released.
Local councillor Paul Marfleet said: “I had several calls from concerned residents who saw the fire, which burned for over two hours.
“I went up to the site and the police and fire service were there, but there was little they could do to tackle a fire 75 metres above the ground and I did sympathise.”
A fire service spokesman said a crew from Denbigh attended the scene, but took no action.
An engineer from Hg Capitals, who run the site, was called to deal with the blaze but no-one from the company was available for comment last night.
Cllr Marfleet added: “I have been looking into this on the internet and it seems it is quite a common thing.
“Turbines are catching fire quite regularly – it’s something to do with the gearbox overheating.
“These particular turbines are very close to trees and there was a lot of debris left behind in them this morning.”
