Following a fire in one of the Vestas V-66 turbines at the Muiderhoek wind farm near Almere, owned by NUON, Vestas has replaced the low-wind speed start up system in all ten of the plant's turbines. The fire, in early July, burnt out the nacelle, rotor and the uppermost section of the three part, 67 metre tower. Firemen arriving on the scene were unable to tackle the blaze directly as their ladders were too short. The fire is thought to have been caused by a short circuit in the low-wind cut in system. The wind station is fully operational again.
