A 90ft turbine in Aberdeenshire has fallen after being battered by 70mph gales. "It's worrying because there are so many turbines in this area. If someone had been walking by when this came down it could have been very serious."
"While there was no malfunction or abnormality with the turbine or tower, there was a problem with the structural grout and the manner in which the tower was fixed to the foundation that affected the durability of the anchor rods resulting in the tower collapse."
The manufacturer of a wind turbine which collapsed in north Cornwall has written to other owners over concerns about the turbine towers' construction. Scottish firm Gaia-Wind has identified a potential problem ...It has written to the owners of 15 of the same turbines to help "in checking their foundation fixing systems for reassurance".
The Canadian manufacturer of a large wind turbine which toppled during gales has denied the device was faulty, following an internal investigation. But the collapse in Devon last week has prompted a fresh probe by the firm into the safety of 20 identical models, including some at sites in the Westcountry.
Local resident Sheila Lawes said people in the area are concerned about the dangers if a turbine gets damaged. Another turbine was about to be erected at nearby Piper's Pool and a fresh investigation has now been launched after a second tower was said to have been toppled during high winds in North Cornwall.
Manufacturer Dulas said it did not suspect sabotage but a full investigation is underway. Bradworthy Parish Council chairman Margaret Coles said: "We know the bolts are gone but don't know what caused it." ..."I don't know how someone would sabotage them because the bolts were under the concrete.
Safety concerns have been raised over wind turbines and a fresh investigation has now been launched after a second tower was said to have been toppled during high winds in Cornwall. ...In the House of Commons yesterday, Energy Secretary Ed Davey warned wind farm operators to make sure their equipment is safe.
Apart from being ugly, noisy, expensive, inefficient, destructive to wildlife and incapable of doing the one thing that notionally they're supposed to do - "reduce CO2" - they are also BLOODY DANGEROUS.
Margaret Coles, Chairwoman of Bradworthy District Council, said hail storms and strong winds have hit the area and the turbine, installed just three years ago, simply could not withstand the wind. "The bolts on the base could not withstand the wind and as we are a very windy part of the country they [the energy company] have egg on their face," she said. "There are concerns about safety."
Blades from an 18m high wind turbine have snapped off after a night of heavy rain and winds. The turbine in a field near Bishop Auckland was built last year after planning permission was granted in November, 2011.
The turbine at East Ash Farm is currently lying flat on the ground after falling over in the early hours of Sunday morning, prompting local speculation it was caused by Saturday night’s high winds.
Wobbly wind turbines will be shored up next month in a project bosses described as "an interesting engineering challenge". Engineers discovered earlier this year that grout connections on the foundations of turbines at the Kentish Flats wind farm, off the coast of Whitstable and Herne Bay, had shifted slightly, meaning a piece of the turbine had also moved.
One of England's largest onshore wind farms is out of action because of a faulty part. Owner Electricity Supply Board (ESB) said the 22 turbines at Fullabrook Down near Ilfracombe, Devon could be off for weeks.
Kirklees Council yesterday suspended planning applications for a type of windmill manufactured by Brighouse firm Evoco Energy. The move came after high winds ripped blades from the company's turbines in Hepworth and Upper Cumberworth earlier this month.
"Weather-dependent" work is underway to replace a section of the cable ...With the weather being with us we would hope to complete it in February, but there is no guarantee with offshore work." The export cable was installed by now-bankrupt cable-laying company Subocean.
An 82ft high wind turbine which was controversially given planning permission near Shrewsbury last year came crashing to the ground in high winds. The wind turbine, on private farmland in the Wattlesborough area, fell yesterday afternoon.
"Apparently some Dolfor residents reported hearing a big bang over Christmas, which one could wonder - was it the noise of the turbine exploding or hitting the ground? "Walking tracks meander through this windfarm. "It goes without saying that this distance should be greater and that turbines should be nowhere near public footpaths.
The U.K. plans to get one quarter of its electricity from offshore wind by 2020. However, to place this in perspective, at around 11 GW of generating power, at least 7,000 turbines will need to be installed (ignoring for a moment the inconsistency of supply) and it being the start of 2012, this must be done at a rate of 2-3 per day which is an acutely challenging undertaking.
First there were the wind farms that had to be shut down if it got a bit blowy. Then there was the turbine that burst into flames in a gale a month ago. And now three turbines have been wrecked in the latest bout of rough weather - sweeping away any remaining illusions that strong winds simply mean more electricity being generated.
Ryan Gill, of manufacturers Evoco, blamed the exceptionally strong winds for the damage. ...Fraser McLachlan, the chief executive of GCube, a wind turbine insurer, said "It does happen but by the very nature of where wind farms are - they are usually in very sparsely populated spots and therefore the risk of damage to property or to people risk is very very low," he said.
