‗Wind turbine accidents‘, You Tube.

While few would contend that turbines are a major threat to public safety (most deaths and injuries are suffered by those transporting, erecting and maintaining turbines), the wind industry is marked by both a reluctance to admit to accidents and a tendency to cover up the failings of the technology.1

In 2011 RenewableUK admitted that there had been over 1,500 reported accidents/‗incidents‘ in the UK in the previous five years, some of which resulted in deaths and serious injuries. There is no requirement for accidents which do not cause death or injury to be reported. A Minister recently confirmed that, “Neither DECC, nor the Health and Safety Executive (HSE), collect specific data for wind turbine accidents.” 2 Most accidents are not noticed unless damage is spotted by the public and the press report it. Examples of industry cover-ups abound.

The wind industry always tries to play down the frequency of turbine accidents: for example, in Cornwall in 2006, “Part of a wind turbine blade weighing more than half a ton snapped off and crashed into a field during high winds. Operators Cumbria Windfarms said the site has been running since April 1993 and nothing like this had happened there before.” It had, as several locals pointed out: in 1993, a month after the turbine park opened, they had had a similar accident.

Then we had a spokesperson for Scottish Power quoted as saying of a blade accident at Whitelee, “This is a highly unusual situation. I've not heard of this kind of incident happening in 30 years.” 3

This may fool some of the public, but, as is evident from this page, blade failures are fairly common and there were several instances just in the North East and Borders when only a handful of turbines were operating in the area.

The Danes are rather more honest. The Technical Approval Authority at the Risø National Laboratory revealed in 2008 that they had recorded the collapse of 15 turbines in the previous three years.4

A Dutch company whose core business is blade repair admits that, “Rotor blade lightning damage is a common problem.”. 5

German turbine fire. ‗SEND US YOUR BURNOUTS, WE ACCEPT TRADE-INS‘ (Generator Manufacturer's Slogan)

Turbine fires are nearly as common as blade accidents, which is no great surprise when you consider that turbines have a combination of large volumes of lubricants, highly stressed bearings and electrical generating sets - brought together at the top of a very high lightning conductor.

Modern turbines are too high for fire fighters to use ladder equipment. Unless firefighting helicopters are available, turbines are normally left to burn out, burning off large quantities of oil, plastics and other noxious materials in the process.

Catastrophic Danish turbine accident, Live Leak video (22.02.08). SAFE SEPARATION DISTANCES

The propensity of very large industrial wind turbines to catch fire, shed blades or bits thereof, throw ice and, occasionally, to suffer catastrophic, high speed blade failures followed by a tower collapse leads sensible people to question their construction close to houses or transport routes.

The world wide problem of turbine noise nuisance also underlines the need for sensible separation distances.

Other countries have acted on that conclusion. In Scotland there is planning guidance (SPP 6, Renewables) which suggests a 2 kilometre separation distance. Similar separation distances have been put in place in other countries, in Europe, parts of Australia, Canada and the US.

Nothing so sensible exists in England and Wales. If anything, things have got worse. In the 1990‘s the DTI was suggesting a 450m separation distance for turbines that then were a maximum of 60m high. Now, with 125m turbines the norm, and turbines of up to 200m being built in France and Germany, there is no suggested cordon sanitaire and we are entirely at the mercy of developers and the haphazard decisions of local planning authorities, many of which have little experience or understanding of wind turbines. Road and Rail

The Highways Agency recognises the risks but fails entirely to recommend a separation distance which would protect road or rail users from a turbine accident:

Consideration of the risks associated with structural failure and ‗icing‘ identifies the clear need to incorporate a safety margin in the offset between the trunk road boundary and the siting of a wind turbine. Therefore, it is appropriate to achieve a set-back from the nearest highway boundary equal in distance to their height + 10% for micro and small turbines. Commercial turbines should be set back a distance equal to their height + 50 metres. (Network Services, Spatial Planning Advice Note: SP 12/09, ‗Planning applications for wind turbines sited near to trunk roads‘, 13).

As is evident from accident reports on this page and academic studies of blade throw, large turbines can throw very large blades, or pieces thereof, weighing many tonnes, for hundreds of metres. Noise The industry routinely proposes building 100-140m turbines within 500m of housing although they are well aware of the noise problems with large turbines. ―A STANDARD PRECAUTIONARY MEASURE‖

Images and video available on EPAW website.

“As a standard precautionary measure, all Infinis staff vacate wind farms when wind speeds exceed 55 mph and therefore no one was present on site at the time of the incident,” (Press release from Infinis regarding the Ardrossen wind farm fire, 8 December 2011).

That must be a comfort to neighbouring members of the public. TWO FACES OF THE WIND INDUSTRY: THE SPIN: ―Fancy a fun-filled family day out at your local wind farm this Bank Holiday Weekend? This August Bank Holiday (27/28 August), on the last weekend before schools go back, families across the UK will be able to visit a working wind farm and touch a turbine as part of the first ever, simultaneous nationwide opening of wind farms – and all for FREE.‖ (BWEA Press release). INDUSTRY WARNINGS:

Turbine operating manuals and site noticeboards tell a different story:

Vestas, ‗Mechanical Operating and Maintenance Manual, V90 – 3.0 MW‘ (29.06.2007).

The BWEA‘s irresponsibility in encouraging thousands of children to touch electricity generators, and Powergen‘s [now E.ON UK] equally notorious „Hug a turbine‟ TV advertising campaign, eventually caused such an outcry that the wind industry‘s friends at the DTI were forced to issue a warning:

“We would not normally advise any member of the public to make contact with installations being used for the supply of electricity,” said a DTI spokesman. “Though the risks to the public from wind turbines are minimal they are large industrial structures and it is sensible to take precautions.” (‗Warning: don't hug a wind turbine‘, The Times, 28 May, 2006).

Apparently PR trumps common sense. Wind power station operators continue to ignore safety advice from their own industry and the government:

―There was a range of children‘s craft activities which included making wind chimes, wind socks and there was the opportunity to leave your hand print on one of the turbines‖ [our emphasis]. (‗Duns nursery benefits from Black Hill wind farm cash‘, Berwickshire News, 9 June 2010. Article refers to wind industry open day event).

Can you imagine the outcry there would be in parliament and the press if children were invited to leave handprints on electrical transformers? ‗WUTHERING HEIGHTS - THE DANGERS OF WIND POWER

Spiegel Online, August 20, 2007. „Wind turbines continue to multiply the world over. But as they grow bigger and bigger, the number of dangerous accidents is climbing. How safe is wind energy?

‗After the industry's recent boom years, wind power providers and experts are now concerned. The facilities may not be as reliable and durable as producers claim. Indeed, with thousands of mishaps, breakdowns and accidents having been reported in recent years, the difficulties seem to be mounting. Gearboxes hiding inside the casings perched on top of the towering masts have short shelf lives, often crapping out before even five years is up. In some cases, fractures form along the rotors, or even in the foundation, after only limited operation. Short circuits or overheated propellers have been known to cause fires. All this despite manufacturers' promises that the turbines would last at least 20 years.

‗Gearboxes have already had to be replaced “in large numbers,” the German Insurance Association is now complaining. “ In addition to generators and gearboxes, rotor blades also often display defects,” a report on the technical shortcomings of wind turbines claims. The insurance companies are complaining of problems ranging from those caused by improper storage to dangerous cracks and fractures.

‗[...]

‗Wind power expert Martin Stöckl knows the problems all too well. The Bavarian travels some 80,000 kilometers (49,710 miles) across Germany every year, but he is only rarely able to help the wind farmers. It is not just the rotors that, due to enormous worldwide demand, take forever to deliver, but simple replacement parts are likewise nowhere to be found. “You often have to wait 18 months for a new rotor mount, which means the turbine stands still for that long,” says Stöckl.

‗“Sales Top, Service Flop” is the headline on a recent cover story which appeared in the industry journal Erneuerbare Energien. The story reports the disastrous results of a questionnaire passed out to members of the German WindEnergy Association asking them to rank manufacturers. Only Enercon, based in Germany, managed a ranking of ―good.‖ The company produces wind turbines without gearboxes, eliminating one of the weakest links in the chain.

‗Even among insurers, who raced into the new market in the 1990s, wind power is now considered a risky sector. Industry giant Allianz was faced with around a thousand damage claims in 2006 alone. Jan Pohl, who works for Allianz in Munich, has calculated that on average “an operator has to expect damage to his facility every four years, not including malfunctions and uninsured breakdowns.”

Many insurance companies have learned their lessons and are now writing maintenance requirements -- requiring wind farmers to replace vulnerable components such as gearboxes every five years -- directly into their contracts. But a gearbox replacement can cost up to 10 percent of the original construction price tag, enough to cut deep into anticipated profits. Indeed, many investors may be in for a nasty surprise. “Between 3,000 and 4,000 older facilities are currently due for new insurance policies,” says Holger Martsfeld, head of technical insurance at Germany's leading wind turbine insurer Gothaer. “We know that many of these facilities have flaws.” ‗Flaws And Dangers

‗And the technical hitches are not without their dangers. For example:

 In December of last year, fragments of a broken rotor blade landed on a road shortly before rush hour traffic near the city of Trier.

 Two wind turbines caught fire near Osnabrück and in the Havelland region in January. The firefighters could only watch: Their ladders were not tall enough to reach the burning casings.

 The same month, a 70-meter (230-foot) tall wind turbine folded in half in Schleswig-Holstein -- right next to a highway.  The rotor blades of a wind turbine in Brandenburg ripped off at a height of 100 meters (328 feet). Fragments of the rotors stuck into a grain field near a road.

‗At the Allianz Technology Center (AZT) in Munich, the bits and pieces from wind turbine meltdowns are closely examined. “The force that comes to bear on the rotors is much greater than originally expected,” says AZT evaluator Erwin Bauer. Wind speed is simply not consistent enough, he points out. “There are gusts and direction changes all the time,” he says.

‗But instead of working to create more efficient technology, many manufacturers have simply elected to build even larger rotor blades, Bauer adds. “Large machines may have great capacity, but the strains they are subject to are even harder to control,” he says.

‗Even the technically basic concrete foundations are suffering from those strains. Vibrations and load changes cause fractures, water seeps into the cracks, and the rebar begins to rust. Repairs are difficult. “You can't look inside concrete,” says Marc Gutermann, a professor for experimental statics in Bremen.“It's no use just closing the cracks from above.”

‗The engineering expert suspects construction errors are to blame. “The facilities keep getting bigger,” he says, “but the diameter of the masts has to remain the same because otherwise they would be too big to transport on the roadways.” ‗Not Sufficiently Resilient

‗Still the wind power business is focusing on replacing smaller facilities with ever larger ones. With all the best sites already taken, boosting size is one of the few ways left to boost output. On land at least. So far, there are no offshore wind parks in German waters, a situation that Minister Gabriel hopes to change. He wants offshore wind farms to produce a total of 25,000 megawatts by 2030.

‗Perhaps by then, the lessons learned on land will ward off disaster at sea. Many constructors of such offshore facilities in other countries have run into difficulties. Danish company and world market leader Vestas, for example, had to remove the turbines from an entire wind park along Denmark's western coast in 2004 because the turbines were not sufficiently resilient to withstand the local sea and weather conditions. Similar problems were encountered off the British coast in 2005.

‗German wind turbine giant Enercon, for its part, considers the risks associated with offshore wind power generation too great, Enercon spokesman Andreas Düser says. While the growth potential is tempting, he says, the company does not want to lose its good standing on the high seas.‘ ‗FIRES ARE MAJOR CAUSE OF WIND FARM FAILURE, ACCORDING TO NEW RESEARCH ‘

Imperial College, 17 July, 2014

‗Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research out today.

‗Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today‘s research suggests that incidents of wind turbines catching fire are a big problem that is not currently being fully reported.

‗Researchers from Imperial College London, the University of Edinburgh and SP Technical Research Institute of Sweden carried out a global assessment of the world‘s wind farms, which in total contain an estimated 200,000 turbines. The team found that ten times more fires are happening than are being reported.

Western Morning News, 7 September, 2014.

‗Safety concerns have been raised about the wind energy industry after reports showed two Westcountry turbines collapsed because of faults.

‗The giant masts crashed down on farmland amid initial rumours of sabotage and claims they had fallen victim to severe weather.

‗Documents obtained by the WMN on Sunday have revealed that the towers actually toppled over due to defects and mistakes in the construction process.

‗A 115ft (34 metre) mast at East Ash Farm, Bradworthy, in Devon, tumbled in January 2013, prompting claims of foul play from the local parish council.

‗Around the same time, a 60ft (18-metre) tower sited at Winsdon Farm, North Petherwin – the family farm of Liberal Democrat Cornwall Councillor Adam Paynter - also came loose from its moorings and fell.

‗Subsequent investigations by both manufacturers identified further defects and prompted warnings to other sites, including in Somerset, Devon and Cornwall.

‗Glasgow-based Gaia Wind wrote to owners and overhauled its entire first generation fleet.

‗Canadian firm Endurance Wind Power said it was also concerned about machines on dozens of locations.

[...]‘ WIND TURBINE GEARBOX FAILURES - THE ONGOING PROBLEM It has long been known that wind turbine gearbox, and associated bearing, problems have been, and continue, to be a major problem, with gearboxes often failing only a few years into the expected operating life of the turbine.

This is especially the case in the offshore industry where there have been large-scale gearbox and bearing problems in even relatively recent installations.

This long running problem is so serious that since 2007, the US Government has been coordinating research into it through the The National Renewable Energy Laboratory (NREL),a national laboratory of the US Department of Energy, Office of Energy Efficiency & Renewable Energy.

NREL, ‗Gearbox Reliability Collaborative Project Report‘, 2011 (PDF download). ‗MORE DISASTERS AT SEA BY WIND TURBINES‘

NL Times.nl, 11 November, 2013.

‗The Coast Guard fears more accidents if the number of wind farms along the coast is increased. The North Sea is already one of the busiest seas in the world. If the plans for building even more wind turbines are realized, the chances of accidents will increase, according to Ed Veen, director of the Dutch Coast Guard.

‗Ships are already cramped on the increasingly crowded North Sea. By a growing number of wind turbines, they have to do with even less space. Each obstacle increases the risk of conflict. Veen points to the 100 to 150 ships that become rudderless annually in the North Sea to illustrate the dangers. If only one of those drifts into a wind farm it would cause an incident like the one with the cruise ship Costa Concordia, which cost the Italian state a billion Euros, according to the Coast Guard Director.

[...]‘ HORSES SPOOKED BY SMALL WIND TURBINE AT SHOW

The wind industry loudly disputes that turbines frighten horses. This view has been very publically disproved by incidents involving horses being scared by wind turbines, most recently at the Pembrokeshire County Show: County Show riders express turbine concerns

Western Telegraph, 25 August, 2012.

SEVERAL incidents involving horses being scared by wind turbines on display in the Pembrokeshire County Show ground have led organisers to re-think their tradestand layout for next year.

Concerns were voiced by owners and riders after their horses reacted to the spinning of a small turbine on a stand near the show‘s collecting ring.

Among them was Dave Scourfield, whose own equestrian establishment is set to be in the shadow of Pembrokeshire‘s largest turbine on land near Ludchurch.

His wife, Isobel, was riding through the walkway on her way to the ring when her horse was ‗spooked‘ by the turbine. ―She was thrown off, and he went galloping off into the lorry park, where he fell and cut his leg,‖ said Mr Scourfield. ―This really proves the point that turbines and horses just don‘t mix. This accident could have been avoided if the show organisers had used a bit of common sense and not put the turbine so very close to the horse area.‖ Sarah Whitfield of Penskyber Livery Yard, Letterston, was working a child‘s pony in the collecting ring when it span around, frightened by the turbine‘s movement.

―I managed to stay on, but if a little child had been riding the pony, there could have been a nasty accident,‖ she said.

One of her four-year-old hunters also reared up and bucked when he caught sight of the turbine, she added.

[...] ‗SPINNING TO DESTRUCTION‘

‗Wind power may be one of the cleaner, greener energy sources available, but turbine and blade failures point to dangers that were not anticipated, says Michael Connellan

The Guardian, 4 September 2008

‗David Campbell and his family were asleep in their farmhouse in Northern Ireland when the 16-foot blade from the wind turbine crashed through the roof of his home one windy night in January last year. “It was like a bomb hitting the roof,” he told the Belfast Telegraph. “It shattered the tiles and the blade disintegrated itself.”

‗Campbell was not the only person to see the direct effects of a turbine failure. Just over a year later, in February, a 200ft Vestas wind turbine near the Danish city of Århus disintegrated spectacularly in high winds when a blade came loose and smashed into the central tower, causing the whole structure to collapse. The incident was captured on video camera and footage has been viewed thousands of times on YouTube.

‗Just two days later a turbine close to the town of Sidinge, in Denmark, sent a blade flying more than 300ft before it hit the ground. Keld Boye, a farmer whose land is near the structure, told Danish television: “I drive my tractor and my wife rides horses out there. Just think if we'd been out there when it happened.”

‗After Denmark‘s climate minister demanded an investigation, authorities found the blade loss was caused by a lack of maintenance: regular checks on bolts in the turbine had been neglected. The Danish government announced mandatory service checks for every one of the 5,000 wind turbines in the country. ‗Cracking up

‗Turbines in Britain - there are 2,000, almost all of which are onshore - aren‘t immune from failure. A 200ft turbine at a wind farm in Kintyre collapsed last November in a 50mph wind. Following that, 26 wind turbines across Scotland were shut down as a precautionary measure while the broken structure was examined. Then the following month in Cumbria, a 100ft steel turbine crashed to the ground.

‗Six months later, in June, as concerns over the incidents last year were receding, a blade cracked away from a 190ft turbine on a Sheffield University research park. Police evacuated the area while engineers allowed the 30ft blade to fall to the ground. The turbine was made by WES, a Dutch company. Earlier that month, the British government had published its renewable energy strategy - with plans to build around 4,000 new onshore wind turbines.

Renewable Energy World,6 Augyst, 2013.

‗LONDON -- Claims for blade damage and gearbox failure top the table for U.S. insurance payouts, according to a new analysis from GCube. ‗Using data based on reported claims in the U.S. for 2012, the analysis shows that blade damage and gearbox failure account for the greatest number of losses — accounting for 41.4 percent and 35.1 percent of the total claims reported, respectively.

‗Meanwhile, damage to generators (10.2 percent) and transformers (5.1 percent) ranked third and fourth in the report, with damaged to foundations coming in fifth in terms of claims volumes.

‗Although the majority of wind turbine blade damage can be attributed to lightning strikes, delamination and improper handling during the construction and installation phase are also frequent and need to be addressed.

[...]‘ ‗60% OF TURBINES MAY BE BEHIND IN CRITICAL MAINTENANCE‘

Windtech International, Monday, 04 August 2008.

‗Frontier Pro Services of Banning, California conducted an informal survey of approximately 75 wind farm operators in the United States.‘

‗Designed to assess the specific operation and maintenance service needs of wind energy operators, the survey reveals potentially serious threats to wind farms owing largely to the industry-wide shortage of qualified turbine technicians. Many wind farm operations and maintenance teams are so resource constrained that they are barely able to keep up with the unscheduled maintenance repairs their wind turbines require to generate electricity. Even regular, scheduled preventative-maintenance like oil changes and gearbox lubrication (services that are often still under warranty) are falling behind as manufacturers face similar resource struggles related to the shortage of qualified technicians. Gearbox failures account for the largest amount of downtime, maintenance, and lose of power production. These costly failures can total 15-20% of the price of the turbine itself, making wind turbine and gearbox maintenance a high priority. If oil is not properly monitored and replaced as needed, bearing and gear wear will lead to more serious and costly damage to the drive train. When a US$ 1,500 bearing fails unnoticed, it can lead to production loss and revenue loss including an unscheduled replacement of a US$ 100,000 dollar gearbox and a unscheduled crane cost of up to US$ 70,000 to access the failed components.‘ ANOTHER TURBINE ‗MYTH‘ SHATTERED

The wind industry claim that it is only scare- mongering NIMBY‘s who say that ice throw from wind turbines can endanger the public.

Local residents with ice from the Whittlesey turbine. © PeterboroughToday.co.uk ‗Wind turbine's deadly ice shower

PeterboroughToday.co.uk, 2 December 2008 Residents were left fearing for their safety after shards of melting ice fell on homes and gardens from the blades of a giant wind turbine. For about four hours people in King's Dyke, Whittlesey, had to take cover as huge lumps – some two feet long – showered them from the 80 metre high tower on Saturday morning.

Resident Peter Randall, whose son's house lies a stone's throw away from the turbine, said: "Somebody is going to get killed. There was huge lumps of ice shooting off and landing everywhere.

―No one wants to leave the house because they are frightened and worried about the ice falling.‖

―My son's partner is pregnant and she is now worried sick about her unborn baby.‖

Freezing overnight temperatures had caused the ice to form and after frantic calls to Truro-based firm Cornwall Light and Power, which owns the turbine, the £2 million machine was eventually turned off.

SECOND LOCAL ACCIDENT WITH HANNEVIND TURBINE

A second Hannevind turbine in the local area has suffered a serious accident.

The 31m Hannevind turbine at Tillmouth Farm, near Norham, north Northumberland, suffered a catastrophic blade failure in February, with large pieces of blade falling to the ground. It has now been dismantled and removed from the site.

The turbine was sited next to a public footpath.

In December 2011, a 30.3m Hannevind turbine was deliberately collapsed by its builder after suffering a runaway brake failure in high winds, only two weeks after it was commissioned (see below).

It was subsequently revealed by Maden Eco, the turbine builders, that Hannevind had been declared bankrupt in October 2011, shortly before the turbine was commissioned.

FARM TURBINE DAMAGED IN HIGH WINDS

A blade has failed on a 71m farm turbine at Low Horton, near Blyth.

Local people noticed on 18 April, 2013, that the twin- bladed, French Vergnet turbine had suffered serious blade damage.

The whole structure was subsequently lowered for repairs.

WINGATES TRANSPORT PROBLEMS

Following on from the major problems caused by an overturned turbine transporter travelling to the Green Rigg site, local people were surprised that the transport of only six turbines to the Wingates site should again cause problems. They experienced delays and diversions when first a mobile crane skidded off the road, followed at a later date by a transporter vehicle getting stuck trying to negotiate a bend and hill.

Questions have continued to be raised about safety, regulation and costs to the community of turbine transport since the A696 was closed for a week when a giant transporter carrying part of a wind turbine tower crashed off the road at Raylees, near Elsdon.

The transporter was part of a convoy carrying turbine parts from Blyth to Green Rigg, near Ridsdale, where Wind Prospect are building 18 Vestas V80 turbines for French-owned EDF Energy. The transport route had been designated as the A68, but was changed by the delegated decision of a Northumberland County Council planning officer after a transporter had grounded on the southern section of the A68.

The Chinese-made tower section is 45m long (147ft) and weighs 56 tonnes. It was eventually recovered on 31 May and returned, this time with a substantial police escort, to Blyth for inspection and repair.

Local people continue to query the suitability of this route and why the crashed transporter apparently did not have a proper police escort. Meanwhile, businesses in Otterburn were left severely our of pocket, losing thousands of pounds from loss of trade.

COLDINGHAM TURBINE COLLAPSED

A 30m turbine near Coldingham was deliberately collapsed by its constructors, Maden Eco, after going out of control on Wednesday, 7 December, 2011.

Lothian and Borders Police said the turbine “suffered brake system failure and had been freewheeling” in 50mph winds.

Nearby houses had been evacuated and the A1107 shut. The turbine had only been operational for a short time. Simon Maden, MD of Maden Design and Build, said that they had only recently been alerted to the fact that Hannevind, the Swedish manufacturers of the turbine, had gone out of business.

Update

According to a letter from Maden Design to an SBC officer regarding an application for a replacement turbine, the client, ―has suffered a total loss as a result of the manufacturer ceasing trading‖ (letter to SBC Officer, 6 March 2012).

BLYTH TURBINES NOT WORKING FOR NEARLY THREE YEARS

The two Blyth offshore turbines, after an early blade failure and cable fault, were out of service from April 2006 until January 2009 due to damage to a power cable on the seabed.

WANSBECK HOSPITAL TURBINE FAILS

A Freedom of Information request by Windbyte in 2009 regarding output figures revealed that the landmark Wansbeck Hospital wind turbine at Ashington, Northumberland, had not been working since 2007.

The small (33m) Vestas turbine in the hospital car park, which was commissioned in 1992, was shut down after a blade began to come apart. This is a fairly common problem, even with newer 125m-plus wind turbines.

A statement from Northumbria Health Care Trust said that: “We have commissioned an external report which will look into the feasability of repairing and re- commissioning the turbine or, if not practical, the alternative uses which the turbine may be put.” The trust could not reveal how much the turbine cost, as it was included in the hospital‘s original capital costs.

The turbine has averaged 14.3% of its headline capacity of 0.1MW since it was commissioned. The British Wind Energy Association has long claimed that,“Over the course of a year, it [‗a modern wind turbine‘] will typically generate about 30% of the theoretical maximum output.”.

KIRKHEATON TURBINES AT A STANDSTILL FOR NEARLY TWO YEARS

Two of the three 66.5m turbines at Kirkheaton, which were put up less than 10 years ago, have not operated since Autumn 2008 due to blade faults on two of the turbines.

The turbines were supposed to be removed if they did not operate for six months or longer, but EDF, the French operating company, has been granted a second 12 month variation on the planning conditions by Northumberland County Council.

EXAMPLES OF UK ACCIDENTS

‗Council blew cash on wind turbines that don‘t work‘

Milton Keynes Citizen, 16 May, 2014.

‗Three costly wind turbines built in the grounds of a school are now to be dismantled – after allegedly generating just £3.67 worth of electricity in NINE years.

‗Milton Keynes Council paid £170,000 for the giant turbines at Oakgrove School at Middleton.

‗But shortly after the school opened in 2005, the structures were switched off for health and safety reasons due to a manufacturing defect.

‗A source told the Citizen: ―It all seems to be an extraordinary waste of money. None of it is the fault of the school itself – they‘ve just been stuck with these huge things that have proved useless.‖

‗The turbines were provided by a German company which has since gone into liquidation, leaving the council unable to get compensation.

‗But this week there was finally a sunny outcome to the sad saga. The council has negotiated with another contractor to remove the turbines for free and replace them with solar panels.

BOLTS NOT UFO‘S!

Failed Conisholme turbine, © Telegraph.co.uk

Dale Vince of Ecotricity has been assiduous in spreading the silly story that the turbines which suffered catastrophic blade failure at his Conisholme power station might have been struck by a UFO or some other mysterious external agent:

‗It was Mr Vince's willingness to consider paranormal explanations that drew attention to the UFO theories, and he told the Telegraph he was disappointed by the results [of the tests].‘

As most sensible people with any knowledge of the wind industry know, it is never UFO‘s, little green men or sabotage by low-flying NIMBY‘s on broomsticks which are responsible for the frequent failure of turbine blades. It is the more mundane story of poor design, defective construction, material failure, lightning strike or poor maintenance (or permutate any combination). The usual consequences are loss or break up of blades, sometimes resulting in the catastrophic collapse of the entire structure as blades impact on the tower.

Unsurprisingly, Enercon, the manufacturers of the Conisholme turbines, have now discovered that the bolts attaching a blade failed. This is of little comfort to people who live close to massive turbines with 40 to 50m long blades that weigh 8 to 12 tonnes (61.5m blades now being built weigh nearly 18 tonnes). Broken blades, or pieces thereof, have travelled hundreds of metres in previous blade failures.

‗Gay‘s home in Varysburg is surrounded by wind turbines - 58 of them. The General Electric 1.6 megawatt turbines were recently installed by Invenergy at the Orangeville Wind Farm.

‗The turbines are big. From the base to the tip of an upright blade, they stand at 425 feet tall. Each individual blade is 160 feet long and weighs 200,000 pounds.

‗The loud noise Ginny woke up to Sunday morning wasn't thunder or a cannon. It was a blade from a turbine behind her home crashing to the ground.

‗German media focus on turbine fires ‘

Windpower Monthly, 31 October 2013

‗Several onshore wind turbine fires in Germany in recent months have triggered media interest, with even financial newspaper Handelsblatt reporting a single turbine fire in Saxony Anhalt.

‗The Saxony Anhalt incident happened at a three-turbine project near Klein Rodensleben on 27 October 2013 during stormy weather. The local fire-fighting association Feuerwehrverband Börde e.V. said the nacelle burnt out completely and a burning blade fell to the ground. ‗Burning debris flew several hundred metres but no one was hurt and the fire did not spread on the ground, the fire association reported that day. Vestas said Handelsblatt‘s claim it was one its turbines was incorrect.

‗Speaking to Windpower Monthly, Energiequelle, which owns the Windpark Wanzleben-Rodensleben, said the turbine was a Fuhrlander 1.5MW. He said the fire was due to a technical fault, not the storm.

‗Other recent turbine fires include an Enercon 800kW turbine that went up in flames at the Windpark Sande on 11th October 2013, the NWZ-Online newspaper service reported 15th October 2013.

‗A fire has consumed one of the three wind turbines at Schlossbühl /Kempfenbühl above the Langenhard. Initial estimates of the cost of the damage are one to two million Euros according to Arno Markowsky, CEO of Freiburg green energy group.

‗At 12.38, the alarm was received at the control center. The column of smoke was widely visible in the Rhine valley. In order not to bring his men into danger, Fire Chief Thomas Happersberger decided not get close.

‗It is presumed that the fire broke out in the generator. The cause of the fire is still unknown. The operators have experts on site. With a rotor diameter of 77 meters, Happersberger decided to shut off the windmill.

‗Happersberger requested additional forces of the riot police and the police to secure a wide area in the forest paths on the ridge between Lahr and Seelbach to prevent any onlookers being endangered.

‗Barely an hour after the fire was reported the first rotor blade was in flames. Just ten minutes later it crashed noisily to the ground, producing a cloud of toxic black smoke. The rotors are made of glass fiber composites, the tower itself from steel. [Our translation].

‗Repair work on VA hospital‘s turbine project hits a snag‘ (Minnesota,USA)

SCTimes, 12 July. 2013.

Work is underway at St. Cloud VA Health Care System to repair a wind turbine that‘s been idle for most of the past 12 months.

But those efforts were hindered by the latest in a string of setbacks this week when a replacement gearbox for the turbine, expected to get the machine working as soon as this week, was discovered to have been damaged during shipment from India.

But the damage shouldn‘t significantly delay the repair timeline, St. Cloud VA Health Care System public affairs officer Barry Venable said Friday. The damage should be able to be repaired on-site.

VA officials hope the turbine will be generating power again as soon as next week, depending in part on wind conditions that can slow repair work.

It‘s the latest development in the ongoing effort to bring the turbine up to speed after more than two years of false starts. The 250-foot-tall turbine that looms near Minnesota Highway 15 has made the issue all the more noticeable.

The turbine has been out of operation for all but about one hour since August 2012 and has operated only about 20 percent of the time since it was installed in 2011, Venable said.

‗FIRE THAT DESTROYED $4 MILLION WIND TURBINE RAISES SERIOUS QUESTIONS OVER LACK OF REPORTING REQUIREMENTS‘ (USA) Wind company fails to call fire department, lets blaze burn overnight

East County Magazine, San Diego County, California.

‗April 27, 2013 (San Diego‘s East County)—Why is there no federal requirement for wind farm operators to report fires?

‗That troubling fact came to light following a turbine malfunction that caused a fire, destroying a $4 million wind turbine at the Kibby Mountain facility in Maine. Opponents accuse Trans-Canada of a cover up, the Bangor Daily News reports. (Trans-Canada, builder of the project, is also the company seeking to construct the controversial Keystone Pipeline.)

‗A sensor in the turbine detected the fire. But an employee did not arrive on scene until the next morning, after the fire had burned itself out. The fire department was never notified, nor was any state agency. Had the blaze not occurred in winter with snow on the ground, the fire could have spread to the adjacent forest, a Maine forestry official has stated.

‗ECM has asked Cal-Fire in an e-mail whether wind facility operators are required to report fires to fire officials. No response has been received.

‗The turbines were made by Vestas. The company‘s turbines have previously been involved in fires elsewhere, including an April 2013 fire in Ontario, Canada, a March 30, 2012 fire in Germany a June 2012 fire in Spain, and a 2011 fire in Scotland in which a turbine ignited in high winds.

‗The wind industry claims wind turbine fires are rare. But the facts suggest otherwise. Vestas is not the only manufacturer plagued with fires linked to equipment failures. Hundreds of fires have occurred, and likely more, since there is no reporting requirement in many locations.

‗Two brush fires in California in July 2012 were caused by wind turbines. A wind turbine fire in Riverside caused a wildfire that burned 367 acres; nearby residents in a box canyon narrowly escaped disaster. Also last summer, a wind turbine sparked a grass fire in Tehachapi.

‗The website ―Turbines on Fire‖ observes that ― you only have to look at insurers‘ reports to get a better understanding of accident rates and insurance claims made by wind energy developers to get a truer account of the health and safety aspect of turbines. According to the IMIA Insurance of Wind Turbines report, a report that was compiled based on 15 years of the Wind Energy industry in Danish markets; Mechanical faults (blade failure and other faults) accounted for 40% of claims, Lightning accounted for 20% of claims, Fire accounted for 7% of claims, Storm accounted for 4% of claims, Liability for 0.5% of claims, and Others (LOP, short circuit, etc.) accounted for 28.5% of claims.

‗In December 2011 the Daily Telegraph reported that RenewableUK confirmed that there had been 1500 wind turbine accidents and incidents in the UK alone in the past 5 years.

EPAW summary: ‗Media commentators said the turbines‘ braking system failed, the machines revved up and caught fire. One of them exploded, sending burning debris into the vegetation and starting fires. Thank God it had rained two days before, said a woman to the journalist, but had this occurred in August, it would have been a different matter. The radio commentator said a similar incident occurred 8 years ago at the same windfarm.‘

‗VESTAS WIND REPORTS PART OF BLADE BROKE OFF V112 WIND TURBINE PROTOTYPE‘ (Denmark)

Bloomberg, 9 September, 2010.

‗A portion of the blade on the first prototype of the Vestas Wind Systems A/S V112 wind turbine broke off late yesterday in Denmark, Michael Holm, a spokesman for the company, said.

‗A six- to seven-meter (20 to 23 feet) portion came off the blade at the turbine in Lem, western Denmark, Holm said today in a telephone interview from Randers, Denmark. “We‟re looking into the root cause. We don‟t see this as a design error.”

‗LIGHTNING STRIKE BURNS DOWN WIND TURBINE‘ (USA)

Sioux City Journal (Iowa), 2 August, 2010.

‗A lightning strike started a fire in a wind turbine Saturday morning, destroying the turbine and one of three new blades that had been laid out on the ground beneath it in order to be installed as replacements. Damages totaled $760,000, according to Peterson Fire Chief John Winterboer.

‗The turbine was owned by Aes Wind Generation Inc., of Alta Iowa. ‗Winterboer said the call came in at 7:30 a.m., but firefighters were on the scene until 3:30 p.m. because they had to wait for the turbine and its three blades to burn enough to fall the 210 feet to the ground before they could extinguish the smoky blaze.

‗TWO WIND TURBINES SELF- DESTRUCT IN ONE WEEK‘ (Denmark & Sweden)

Copenhagen Post, November 3, 2009.

‗Wind turbine blades rip loose near Esbjerg and southwestern Sweden, one landing on a hiking path.

‗A malfunction on a Vestas wind turbine in the town of Falkenberg on Sweden‘s southwest coast could have resulted in tragedy, as one of the structure‘s large blades flew off and landed on a track used by hikers.

‗Yesterday‘s incident follows a similar one this weekend near Esbjerg, where a defective axle caused all of the blades on a 40m high turbine to rip loose, one of them hitting a power transformer.

‗Both wind turbines were produced in Denmark.

‗And, although no one was injured in either incident, the accidents have brought the problem of faulty wind turbines into focus. The wind turbine industry in Sweden has now proposed setting up a commission to investigate the many incidents.

ANOTHER AMERICAN TURBINE COLLAPSE

‗Noble Environmental Power Confirms Altona Turbine Collapse‘

WPTZ.com, March 6, 2009.

‗ALTONA, N.Y. -- Noble Environmental Power has confirmed that a turbine collapsed at its Altona, N.Y., wind park Friday morning, but said no one was injured in the collapse and ensuing fire.‘ [...]

‗Residents reported large explosions from the scene at about 9:30 a.m. NewsChannel 5 went to the scene off Purdy Road, which leads to the wind farm, and found Noble trucks blocking the roadway. Noble officials at the scene would not provide access to the area and offered no information about the situation at that time.‘

‗Residents in the area told Newschannel 5 they heard what sounded like a large explosion and said the loud noises lasted for several minutes. Others equated the sound to an earthquake and speculated one of the company's large windmills may have thrown a blade. Another local resident told NewsChannel 5 she could see flames coming from Noble.‘

Update

‗The investigation by New York‘s Department of Public Service found that the collapse of one turbine and failure of a second at the 65-turbine Noble Altona Windpark was the result of a wiring system that prevented the turbines from being automatically shut down in the event of a loss of electric power.‘

‗MORE THAN 10 DANISH WIND TURBINES WRECKED IN 3 YEARS‘

The Engineer, 26 February 2008.

‗The collapse of a wind turbine is far from unique in Denmark, the Technical Approval Authority at Risø [National Laboratory] states. It has happened between 10 and 15 times in the last three years, and poor maintenance is the most frequent cause. [...]‘ [Our translation].

MINISTER DEMANDS EXPLANATION FOR TURBINE COLLAPSES (Denmark)

The Danish Climate Minister, Connie Hedegaard, called for an investigation to determine the cause of the two violent wind turbine collapses in Denmark in one week in February 2008. Hedegaard's request to the Energy Board came after other accidents were reported in Denmark and elsewhere during the previous two months.

Catastrophic Danish turbine accident, Live Leak video (22.02.08).

The author of the Danish video clip comments:

―The braking system failed while 2 technicians worked in the turret in the top. They got out before the collapse. A 19 metre piece of the wing was thrown 200 metres away. Smaller pieces were sent more than 500 metres away..!!‖

‗BAD GLUING BLAMED FOR MISHAPS AT WIND FARM‘ (USA)

‗It all came down to glue. And how it was misapplied by workers. Spanish wind-energy company Gamesa said “insufficient and irregular distribution of glue” caused large pieces to break off seven turbine blades at the Allegheny Ridge Wind Farm near Lilly, Cambria County. No one was injured during the mishap in mid-March, but pieces of the blades flew more than 500 feet, according to residents.

‗From a distance, it is hard to comprehend how large the Gamesa turbine blades are - 140 feet long, about 14 feet wide and weighing about 7 tons, according to the company.

‗"It's something the size of a yacht flying through the air," said Brian Alger, an analyst who covers the wind-energy industry for Strata Capital Management in Beverly Hills, Calif.

‗Several of the blade pieces landed on property owned by James A. Davis, 69, of Lilly, and leased in part to Gamesa. One piece was thrown more than 500 feet before coming down through the trees, Davis said. That would put it outside the official 300-foot safety zone around each turbine.

CATASTROPHIC TURBINE FAILURE RAISES DOUBTS ABOUT SAFETY (USA)

Searsburg turbine tower (courtesy IWA)

NEW HAMPSHIRE (October 16, 2008). Turbine #10 at the Searsburg wind energy facility in Searsburg, Vermont experienced a catastrophic failure when one of the blades came in contact with the turbine's tower causing it to buckle during high winds. This turbine's 28-ton nacelle and 3-blade rotor assembly crashed to the ground scattering debris several hundred feet from the structure. Approximately 20- gallons of heavy oil spilled from the unit when its fluid reservoirs were damaged. The 11-turbine Searsburg facility was brought online in 1997 and according to preconstruction documents, the turbines had an expected lifespan of 30-years.

Industrial Wind Action (IWA) Group‘s executive director, Lisa Linowes, was not surprised by the failure. “The Searsburg towers are located at an elevation of nearly 3000-feet in some of the harshest weather conditions in New England. Performance issues and blade failures have plagued this project for some time,” she said pointing to incidences in May 2006 and again in May 2008.

While the eleven-year old Searsburg turbines are failing, newer models have not improved the safety record. “Wind developers today tout life expectancies of industrial wind turbines that exceed 20 years,” Linowes said, “but the fact remains that estimates of the functional lifespan of modern utility-scale wind turbines are speculative and cannot be substantiated since so far very few have been operating for ten years.” Unfortunately, unless a person or property is damaged in a turbine failure, there is no obligation for the owner of an industrial wind turbine to report the incident.

Information on the number and types of failures is sparse and poorly reported, and thus this vital data is not adequately incorporated into estimates of turbine longevity. The Searsburg failure occurred on September 15.

“What's more ominous,” Linowes said, “is that reports of turbine failures in the United States are increasing. These failures include blade throws, oil leaks, fires, and collapse.” IWA attributes the increase in reporting to the fact that the machines are more visible, being erected close to where people live, and also due to the growing interest in wind energy development. In the last year alone, IWA has tracked catastrophic failures in Idaho, Minnesota, California, New York, Pennsylvania and elsewhere, raising concerns about public safety.
