A £2m wind turbine was knocked over by the wind after raging storms and 50mph gales made the blades on the 300ft rotary turn at twice their normal speed.
The turbine, which was almost the height of St Paul’s Cathedral, was torn apart by the raging winds and eventually collapsed to the ground in February.
An investigation, launched by manufacturer Nordex, found a power failure caused the blades to run in an ‘overspeed condition’ for more than four hours and rotate uncontrollably in the 50mph winds.
The energy generators are supposed to automatically switch off after it detects winds of 55mph.
A spokesman for Nordex said: ‘A Root Cause Analysis investigation determined that a technical issue, starting within an Uninterrupted Power Supply cabinet for one of the blades, triggered an unprecedented chain of events in quick succession.
‘This disabled the main power supply and the backup power supply to each blade of the pitch system, therefore all three blades of the wind turbine were left without power resulting in a fixed state.
‘The wind speed conditions on the day increased putting the wind turbine into an overspeed condition until it collapsed.’
Villagers said the huge noise woke them at around 6.50am on a Monday morning in February and echoed around the valley below.
