Energy giant Innogy is investigating after one of its wind turbines was destroyed by a fire.
The turbine - one of eight machines at the Knabs Ridge site near Harrogate - was seen burning on Friday night.
Pictures of the aftermath showed the nacelle, the part at the centre of the blades that contains the generator and gearbox, completely burnt out.
Each turbine at Knabs Ridge, which started generating in 2008, has a capacity of two megawatts.
The nacelles stand 190ft above ground and the blades reach up to 305ft tall. The turbines were manufactured by REpower Systems in Germany.
A spokesman for Innogy Renewables UK said: "As a result of an incident involving one turbine at the Knabs Ridge onshore wind farm in Harrogate, the fire service was called out by on-site personnel on Friday."
The company has launched an investigation to establish the cause of the fire and said there had been no injuries from the incident.
Four of the turbines at the wind farm site are still operating while three that are linked to the damaged turbine remain out of action.
Wind turbine fires are relatively rare, although a study backed by Imperial College has suggested they may be more common than is thought.
One high-profile incident in the UK in 2011 saw a £2m turbine in Ardrossen destroyed after catching fire during hurricane-force winds, reportedly due to a lightning strike.
