“When they were first put up we had a long spell of really nice weather and they weren’t working at all. But since we’ve had the wind and the recent spell of bad weather the noise is unbearable of a night time.”

“It’s unbelievable the noise they make sometimes,” said Mr Paulton, 68.

A Torrington couple are selling their home and business following the erection of a wind farm in a field opposite their bungalow.

Patricia and Arthur Poulton say they are being kept awake at night by the noise from a trio of giant turbines less than 500 metres from their home at Higher Darracott.

The couple, who have operated their Deepmoor Metal Processors scrap metal business from the site for the last 21 years, said they now had no option but to sell up and move on.

“I can hear the turbines through my pillow at night,” said Mrs Paulton, 70.

“It’s a droning whooshing sound and as the blade passes the upright, the windier it gets, the noisier it gets. I have to close the window but you can still just about hear it through the double glazing.

“When they were first put up we had a long spell of really nice weather and they weren’t working at all. But since we’ve had the wind and the recent spell of bad weather the noise is unbearable of a night time.”

“It’s unbelievable the noise they make sometimes,” said Mr Paulton, 68.

“They are supposed to be no more than five decibels above background noise but when the wind blows across the bungalow it’s surprising how far it travels.”

The 240ft turbines were constructed by FIM Services Ltd in March and became operational in April. Planning consent was originally refused by Torridge District Council in May 2004 but later granted by a Government Inspector following a High Court appeal by land owners.

When the Gazette visited the couple on Wednesday, heavy blobs of white and grey cloud blotted out all but a few snatches of blue sky. On the hillside overlooking Torrington, two of the three turbines turned in a stiff breeze.

On the approaches to the town, the first of 22 ESB Wind Development UK turbines can be seen being built at Fullabrook Down on the other side of the Taw Estuary.

When the sun does shine here – especially towards the end of the day – the couple say the blades produce a “flicker shadow” over their bungalow.

“The sun goes down right behind the turbines and you get this strobe effect,” said Mrs Paulton, who suffers from Ménière’s disease – a disorder of the inner ear that can affect hearing and balance.

“They also produce a low frequency noise that you can’t hear but can cause dizziness, nausea and headaches. I’m not sure if it’s a coincidence but I’d not been ill for about five months but as soon as the turbines started I was sick for two weeks and have had to take the medication.

“We had a couple of break-ins at the yard last year and were thinking of selling up, but this has been the final straw.”

The couple have been in contact with Torridge District Council and have been asked to fill in forms to record their disturbance.

A spokesperson for the council said an official investigation had already started.

A statement from the council said: “The necessary forms have been sent to the complainants and our environmental protection team is awaiting the return of the paperwork with a diary of noise disturbances to see whether or not further investigation is required.”

Regarding shadow flicker, it said: “In the planning permission the inspector stipulated that a report should be submitted on shadow flicker which concluded that there would be very little chance of it happening. However, should it occur, effective steps should be taken to stop it.”

The couple were keen to point out that they were not concerned about the turbines’ impact on the landscape.

“We’re not bothered about how they look,” said Mrs Paulton.

The Gazette contacted FIM Service but a spokesperson was unavailable for comment.

Overcoming President Obama's Wind Power Addiction

An alternative form of energy with embarrassingly underwhelming returns.

Cumulative federal subsidies for wind are now well north of $100 billion. The very business running the Pennsylvania facility at which Obama made that bold prediction--Spanish wind company Iberdola--has received an astounding $1 billion in grants, tax credits and other incentives from the U.S. government (a.k.a., you and me).

This spring, Secretary of the Interior Ken Salazar announced federal approval for the construction of a huge new offshore wind farm in Massachusetts. The so-called Cape Wind project will include 130 turbines, each roughly 440 feet tall, and span 25 miles of ocean off the coast of Cape Cod. Construction is expected to commence this fall--assuming the troubling economics of the project can be resolved.

Getting Cape Wind approved was no easy task. The project had been stalled in controversy for nearly a decade. Even the late Sen. Ted Kennedy opposed the turbines for spoiling the tranquility of his seaside vacation home.

But Cape Wind survived its environmental review. And that's in no small part due to the Obama administration. Expanding wind power is core to the president's peculiar, ill-defined green energy agenda. At an April visit to a Pennsylvania turbine manufacturing facility, he went so far as to declare wind "the future of American energy."

That's quite a claim--and hardly true. Our country's history with wind power consists of grand promises from politicians, huge investments of taxpayer dollars, ratepayer sacrifice and embarrassingly underwhelming returns. More of the same can be expected.

Of the $10 billion invested by wind developers last year, $3.4 billion came in the form of federal grants. Thus taxpayers picked up a full one-third of the tab. And ratepayers have no choice but to pay the extra cost from wind power in states that mandate its use even after the tax subsidies.

Cumulative federal subsidies for wind are now well north of $100 billion. The very business running the Pennsylvania facility at which Obama made that bold prediction--Spanish wind company Iberdola--has received an astounding $1 billion in grants, tax credits and other incentives from the U.S. government (a.k.a., you and me).

NOISE RESEARCH TO COMBAT WIND TURBINE SYNDROME

SOURCE: adelaide.edu.au

June 1, 2011

“Wind turbine noise is very directional. Someone living at the base might not have a problem but two kilometres away, it might be keeping them awake at night,”

“Wind turbine noise is controversial but there’s no doubt that there is noise and that it seems to be more annoying than other types of noise at the same level.

University of Adelaide acoustics researchers are investigating the causes of wind turbine noise with the aim of making them quieter and solving ‘wind turbine syndrome’.

They are also developing a computer model to predict the noise output from wind farms so they can accurately and quickly assess the effectiveness of potential noise-reducing designs and control methods.

Research leader Dr Con Doolan, of the University’s School of Mechanical Engineering, said the noise generated from wind turbines is ‘trailing edge or airfoil noise’, the same sort of noise generated at the edge of aircraft wings.

“We know generally what causes that noise – as the turbulent air flows over the sharp edge of the blade it radiates sound much more efficiently, so the noise can be heard at some distance,” said Dr Doolan.

“What we don’t yet understand, however, is exactly how that turbulence and blade edge, or boundary layer, interact and how that makes the noise louder.

“If we can understand this fundamental science, we can then look at ways of controlling the noise, through changing the shape of the rotor blades or using active control devices at the blade edges to disrupt the pattern of turbulence and so reduce the noise.”

Dr Doolan said further complicating factors came from the effects of multiple wind turbines together and the way the noise increases and decreases as the blades rotate – the blade ‘swish’. The model they are developing will look at the noise from the whole wind turbine and how multiple numbers of wind turbines together, as in a wind farm, generate noise.

“Wind turbine noise is very directional. Someone living at the base might not have a problem but two kilometres away, it might be keeping them awake at night,” he said.

“Likewise this broadband ‘hissing’ noise modulates up and down as the blades rotate and we think that’s what makes it so annoying,” he said.

“Wind turbine noise is controversial but there’s no doubt that there is noise and that it seems to be more annoying than other types of noise at the same level. Finding ways of controlling and reducing this noise will help us make the most of this very effective means of generating large amounts of electricity with next to zero carbon emissions.”

Something from the Wind Developer's point of view

IS WIND ENERGY THE NEW WEDGE ISSUE?

SOURCE: North American Windpower

By Jeff Siegel,

Almost as soon as the situation at Japan’s Fukushima Daiichi nuclear plant became critical in March, Fox News reported that wind power had killed more Americans than nuclear energy. Meanwhile, the Texas Public Policy Foundation, a conservative think tank, issued a study that said the state’s taxpayers would be $28 billion better off if Texas abandoned its pro-wind policies.

Wind, after being the darling of the media, business and state governments for much of its history, has suddenly found itself on the receiving end of negative publicity, questions about its value as an energy source and even calls for an end to wind development. The feel-good “green” story, according to the New York Times, “is now nearing extinction.”

Texas, Wisconsin and Minnesota, all considered wind-friendly states, have recently pursued policies that can be seen as anti-wind.

Some of this shift is due to the industry’s natural maturation process, according to David Lowman, an attorney who is co-chair of Hunton & Williams’ global renewable energy practice group in Washington, D.C.

Some of the backlash against wind also stems from the recession, which has not only hampered wind development but has made even previously wind-friendly regulators and legislators question its cost at a time when state and federal budgets are being slashed.

The pushback, says attorney Jim Tynion, who chairs Foley & Lardner’s energy industry team, is genuine and something that the industry needs to address.

The acrimony is being powered by a combination of small-government conservatives who see wind and other renewables as a waste of money and by others who consider wind a technology that will never be as effective as oil, coal or natural gas.

During a Texas ground-breaking ceremony for an oil and gas processing company, Sen. John Cornyn, R-Texas, told KSAT in San Antonio, “I understand that some people want to see green jobs; I think that’s great. We need all of the above when it comes to energy: wind, solar, biofuels and the like. But the fact of the matter is 85 percent of our fuel consumption comes from fossil fuels.”

Cornyn’s comments underscore the political realities that wind energy faces.

“The political landscape has changed,” Tynion says. “It’s easy to take potshots at something that isn’t part of the status quo, like wind. It has become an easy target.”

Certainly, not all has gone badly for wind. The American Wind Energy Association (AWEA) estimates that the U.S. wind power industry grew by 15% in 2010 and provided more than one-quarter of all new electric-generating capacity. Also, California, despite its fiscal problems, will require one-third of the state’s electricity to come from renewable sources by 2020.

But those are the bright spots. Some dark ones include the following:

• The Wisconsin State Legislature is considering a bill that would restrict the development of approximately $500 million worth of projects over the next two years. According to the Milwaukee Journal Sentinel, Republican Gov. Scott Walker says wind costs too much and impedes on rural property rights. The legislature voted in March to suspend wind farm siting rules. The five-to-two vote tracked along party lines, with all five votes to suspend coming from Republican members;

• Texas comptroller, Republican Susan Combs, has decried wind as an expensive boondoggle that does not produce jobs. The state’s GOP-controlled legislature may limit the ability of local school districts to give tax abatements, which wind advocates in the state say will limit development in rural areas; and

• The 2012 extension of the production tax credit could be in jeopardy, given the budgetary concerns on Capitol Hill. Jon Chase, vice president of government relations for Vestas-American Wind Technology, told an AWEA finance and budget workshop in April, “All the credits out there are going to be looked at very closely. Everything is going to be on the table.”

“There are politicians who can make political hay by playing to that constituency,” says Tom Konrad, who manages several green energy stock portfolios and is editor of AltEnergyStocks.com.

As part of this political footwork, Konrad says rhetoric debunking climate change has increased markedly over the past several years, more or less in relation to how many Americans believe that climate change actually exists. If fewer Americans believe in climate change, fewer Americans will support wind and other renewables, he says.

This goes a long way toward explaining the difference in the current political and media attitude toward wind compared to just a couple of years ago. Also important, say wind industry analysts, has been the length and depth of the recession, both in how it has slowed development and made consumers more wary of higher energy prIces.

Whether or not some of these concerns may be warranted, says Tynion, the wind business should not discount the change in the political climate.

“Politicians and state regulators are withdrawing their support for wind across the board,” he says, citing the Wisconsin controversy as a prime example.

Walker’s proposed legislation would overturn a siting compromise three years in the making, says Tynion, adding that the compromise seemed to satisfy everyone involved: developers, rural landowners and regulators.

For its part, AWEA does not support the claim that wind energy is a wedge issue for either political party. “The fact is nine out of 10 voters Republicans, Democrats and Independents – want more wind power, as we found in a recent poll,” says Elizabeth Salerno, AWEXs director of data and analysis. “Specific to Republicans, AWEA found that 84 percent of Republicans believe increasing the amount of energy the nation gets from wind is a good idea.”

Has the backlash irreparably damaged wind? Has the momentum and goodwill built up over the past 20 years been lost? The answer is complicated and depends not only on what happens during the 2012 presidential and congressional elections, but on what the wind industry does over the next several years to regain lost momentum.

“There is still a great deal of support for wind and other renewables, both among Democrats and Republicans,” says Lowman. “And there are plenty of initiatives going on, especially on the East Coast. For example, Virginia Governor Robert F. McDonnell, a Republican, wants to build offshore wind.”

Education also remains key, say several analysts. Focusing on the longterm benefits of wind is important. If the green argument fails to work, there is always the economic one.

Lowman says there is reason to expect that renewable prices will continue to become more competitive with fossil fuels over the next decade.

Anne Mudge, an attorney at San Francisco-based Cox Castle & Nicholson, recommends that wind energy advocates should not let opponents dominate the discussion by focusing on the short term.

“Continue to demonstrate what is the truth – that there are economic benefits to wind, that it brings jobs, that it increases the property tax base and that it doesn’t take much in the way of government services,” she says.

In other words, do what wind has always done – but do it in an even more urgent way. Because, says Konrad, if the argument focuses on the short term, and if wind’s opponents can direct the discussion, “wind will remain a whipping horse.”

WHAT'S BLACK AND WHITE AND YOU CAN'T TALK ABOUT IT FOR THE REST OF YOUR LIFE?

Sorry. I signed a wind lease. I can't discuss it.

NOTE FROM THE BPWI RESEARCH NERD: Better Plan has been collecting copies of wind leases for the last few years and has yet to find one that didn't contain a confidentiality agreement ---also known as a 'gag order'

Landowners who share wind leases are taking a clear risk, but more are coming forward anyway. One farmer who shared his contract said, "I don't care anymore. I just don't want this to happen to anyone else."

The section below is copied from a wind lease contract that came our way. The landowner who signed it agreed to allow noise, vibration, shadow flicker and any other disruption the turbines might cause to take place on his property. If he has problems with these things he can't talk about it because the gag order requires that he:

Not to talk about the contents of lease to anyone. 

Not to talk about the construction or operation of the turbines.

Not not speak to reporters or anyone in the media or issue statements or press releases unless the wind company gives the landowner their written permission.

The landowner also had to agree that the gag order would still apply long after the turbines are gone. This line says it all: "This section shall survive the termination of expiration of this lease"  It means this gag order is forever.

The landowner can talk to his lawyer or accountant and certain others about the contract but only after they agree to a gag order too. 

 STRAIGHT FROM THE CONTRACT:

Confidentiality

(Landowner) shall maintain in strictest confidence, for the sole benefit of (wind developer) all information pertaining to the terms and conditions of this lease, including, without limitation, the construction and power production of the wind farm.

Without first obtaining written permission from the (wind developer), (the landowner) shall not issue any statements or press releases or respond to any inquires from news media regarding such matters.

(Landowner) shall maintain the strictest confidence, for the sole benefit of the (wind developer) all information pertaining to the terms and conditions of this lease, including, without limitation, the financial terms hereof.

This section shall survive the termination of expiration of this lease.

Nothing in this section shall prohibit sharing or disclosing information with any party's (lawyer) accountants or current or prospective investors, purchases, lenders or as required by law, provided that the party sharing or disclosing such information requires the recipient to maintain the confidentiality of such disclosed information

Wind Energy Update: Wind Farm O&M - Best Practice On Cost Containment Elusive

The constantly evolving wind turbine market means that new components must continually be demonstrated, with little assurance of their availability five years down the track in the event of component failure.

Posted on: Monday, 23 May 2011

SOURCE: "Wind Energy Update" VIA PR WEB

When it comes to turning a profit throughout the lifecycle of a wind farm, just a one percent improvement in operations and maintenance can make a huge difference to the bottom line, according to the latest Wind Energy Update Operations & Maintenance Report 2011.

(PRWEB) May 23, 2011

When it comes to turning a profit throughout the lifecycle of a wind farm, just a one percent improvement in operations and maintenance can make a huge difference to the bottom line, according to the latest Wind Energy Update Operations & Maintenance Report 2011. [Click here to download report]

The challenge, however, is how to achieve that one percent improvement in the face of operations and maintenance (O&M) costs that are double or even triple initial projections.

O&M costs under-estimated

On the basis of an exhaustive industry survey, the latest report finds that wind farm return on investment is around -21 percent. This underperformance is attributable to over-estimation of power production and underestimation of O&M costs say the report’s authors.

In the early days, the industry had costed out O&M at roughly 0.5c/kw over a turbine’s 20-year life. But as newer models and their respective components continued to flood the market, this has turned out to be far from the reality.

The report highlights that wind O&M costs can now be expected to increase on average 253 percent over the 20-year life of the various wind machines.

“Given that every wind turbine comprises an average of 8000 components, it is not surprising that higher-than-expected rates of component failure continue to plague the industry,” say the report's authors.

Understanding the root cause

The constantly evolving wind turbine market means that new components must continually be demonstrated, with little assurance of their availability five years down the track in the event of component failure.

Of even greater concern is that, if not properly addressed early on, component failures can persist through new product generations. It is therefore vital, despite pressure from competitors to continuously push the boundaries on nameplate capacities, that both the onshore and offshore industries adopt a backwards compatibility approach when evolving each model.

A thorough understanding of failure trends can also provide a basis for the best O&M practices for a given system, say the reports authors.

Sketching a component failure timeline, the authors characterise earliest wind turbine designs (1987-91) by their gearbox failures, while wind turbines built between 1994-99 are characterized by electronic power failures.

Turbines manufactured between 2000-2004, again exhibit problems with generators and gearboxes. More recent models are plagued with issues linked to retrofits.

Aftermarket potential

But there is a silver lining. Some component suppliers to the OEM wind turbine market view the aftermarket as a new, long-term opportunity.

“Advances in turbine design may make certain parts obsolete, but with a typical projected turbine life of 20 years or more, the aftermarket will provide ongoing spares demand for these suppliers for some time to come”, says the report.

The report also notes that in the long-run, as the wind industry matures and begins to validate the success of condition and performance monitoring systems, as direct drive turbines replace gear-box driven turbines, and as the industry begins to collaborate on O&M, reductions in long-term O&M costs are the most likely scenario.

READING BETWEEN THE (POWER) LINES

Note from the BPWI Research Nerd: Lobbyists and wind developers tell the media that wind projects are being cancelled in our state because of the 'uncertain' regulatory environment, resulting in headlines in the press and on the web like this:

"TURBINE SETBACK RULE SOUNDS DEATH KNELL ON WISCONSIN'S WIND INDUSTRY"

DEVELOPER PULLS PLUG ON WISCONSIN WIND FARM OVER POLICY UNCERTAINTY

LARGE WISCONSIN WIND FARM KILLED BY POLITICS

Similar headlines came when Wisconsin utility, Alliant, recently announced it was cancelling its plans for a wind project in Green Lake County.

WALKER'S WAR ON WIND ENERGY CLAIMS ANOTHER VICTIM

THIRD LARGE WISCONSIN WIND PROJECT CANCELLED DUE TO LEGISLATIVE ACTION

WISCONSIN  WIND RESTRICTIONS COST UTILITY $5 MILLION

The story in the Milwaukee Journal Sentinel began like this:

"Moves to restrict wind farm development in Wisconsin led a Madison utility to take a $5 million charge, citing the difficulty of being able to build the project in Green Lake and Fond du Lac counties."

The '$5 Million dollar charge' appears to be the price paid for the project by Alliant to Florida Power and Light (now known as NextEra) a company with a history of coming into our state to sign up landowners to host wind projects and then selling the leases to utilities. (Apparently undeterred by Wisconsin's 'uncertain regulatory climate' a developer for NextEra is currently prospecting for wind rights in Rock County's Spring Valley Township.)

The purchase of the FPL/NextEra project was reported in March 2009 by Journal Sentinel this way:

"The Madison utility holding company has reached an agreement with NextEra Energy Resources, a unit of FPL Group Inc., to buy wind power from NextEra under a 25-year contract. Under the deal, Alliant also would buy development rights to a future wind farm in the Green Lake area, utility spokesman Rob Crain said....Though specific details about the pricing terms to buy wind power from NextEra are confidential, Crain said, "These are reasonable and cost-competitive projects."

Although the cancellation of the Alliant/NextEra project has been portrayed in the media as another example of Wisconsin politics driving out wind development, the following article sheds light on the real reason Alliant decided to take the $5 million dollar hit and pull out of the project.

Alliant spokesman, Steve Shultz seemed to contradict himself when asked about the reason behind the cancellation of the project.

To Milwaukee Journal Sentinel he said:

"The $5 million charge is in recognition of the fact that it will be much more difficult to build the wind farm given uncertainty in the state’s wind siting requirements, said utility spokesman Steve Schultz."

To The Ripon Press he said:

Schultz emphasized the Green Lake-area wind farm was never a concrete plan or proposal, but rather a possibility.

“At no point have we had any timeline or any specific plan as to say, ‘We’re going to build a wind farm here at such-and-such a date,’” he said.

ALLIANT PASSES ON LOCAL WIND FARM

Explaining why Alliant has abandoned the area development rights, Schultz said the Madison-based utility has reached its “renewable portfolio standard” for the state.

“We’re exceeding that, actually,” he said. “And at this point in time, we don’t see that that requirement is going to increase in the near future.”

Alliant Energy has decided not to pursue a significant wind-turbine farm near Green Lake.

In 2009, the utility company bought development rights from NextEra Energy Resources for a region around the Green Lake-Fond du Lac county line, with the idea of a possible wind farm in the future.

If developed, it may have accommodated about 60 turbines. But this month, the company announced it nixed that idea.

“We’re essentially discontinuing those development rights,” Alliant Energy spokesman Steve Schultz said.

This means Alliant has taken a $5 million loss — the cost to purchase the rights.

This cannot be recouped via utility charges. It just goes down as a loss, he explained.

The decision also means the wind energy rights to that area now are fair game for any other company, Schultz said.

It’s not out of the question that another company may be or become interested, as Alliant previously had noted the Green Lake area as having a “strong wind regime,” thanks in part to Big Green.

Explaining why Alliant has abandoned the area development rights, Schultz said the Madison-based utility has reached its “renewable portfolio standard” for the state.

“We’re exceeding that, actually,” he said. “And at this point in time, we don’t see that that requirement is going to increase in the near future.”

Schultz emphasized the Green Lake-area wind farm was never a concrete plan or proposal, but rather a possibility.

“At no point have we had any timeline or any specific plan as to say, ‘We’re going to build a wind farm here at such-and-such a date,’” he said.

Rather, it was a “potential future development,” he said.

Still, it probably would have been a large wind farm, had it come to pass.

“What we had determined was that the site would accommodate about 100 megawatts ... Probably in the range of 60 turbines,” Schultz said.

As of 2010, Wisconsin was home to nine commercial wind farms, with more than 400 megawatts of wind power capacity, according to the Alliant Energy website.

In this region, Fond du Lac County and northeastern Dodge County are home to five of those nine sites. Turbines can be seen from Highway 41.

“Wind power is the fastest-growing energy source in the world,” the website reads.

Wisconsin Power & Light — a subsidiary of Alliant — operates the Cedar Ridge Wind Farm in Fond du Lac County.

The 68-megawatt wind farm began producing emissions-free energy in 2008. The company’s second wind farm, the Bent Tree Wind Farm in Freeborn County, Minn., began commercial operation in February.

“Just because we’re not going to continue the development rights in Green Lake doesn’t mean we’re not committed to renewable energy,” Schultz said.

FROM PENNSYLVANIA

Note from the BPWI Research Nerd: The wind turbine related bird and bat kill rates in Pennsylvania have made news several times in the past few years with numbers considered to be shockingly high.

Sadly these numbers are far less than the turbine related kill rates in the state of Wisconsin

In a recent Green Bay Press Gazette Article , turbine related bat kills in Wisconsin were reported to be as high as 50 per turbine per year, a number that is not not only ten times what the wind companies say is the national average, but it is considered to be unsustainable. To the best of our knowledge the bat kill rates from wind turbines in our state are the hightest in North America. And to the best of our knowledge no one is doing anything about it.

BLOWING' IN THE WIND

READ ENTIRE STORY AT THE SOURCE: Outdoor Trails, Staff Writer, lancasteronline.com

May 16, 2011

By AD CRABLE,

Since 2007, 73 percent of the owners of wind projects in the state have signed the Wind Energy Voluntary Cooperation Agreement.

Among the notable exceptions is Florida Power & Light and its subsidiaries, which have the most turbines in the state. High bat mortality has been found at some of them.

Are proliferating wind turbines killing a large number of birds in Lancaster County and Pennsylvania? No, say the Game Commission and power companies. You’ll have to take their word for it.

Every other day since March 1, a searcher has walked a grid pattern under the two new wind turbines on Turkey Hill, looking for the carcasses of birds that may have been killed by the turning blades.

So, have there been any bats, tundra swans, birds of prey or endangered songbirds unfortunately whacked by the 135-foot-long blades?

Project owner PPL Renewable Energy and the Pennsylvania Game Commission know, but they’re not telling.

Certainly there is no reason to think many birds are being sliced and diced at the Manor Township site.

But shouldn’t the public be allowed to know if there are? After all, the turbines were partially built with federal stimulus funds, your tax dollars.

How about bird scientists with the Pennsylvania Biological Survey, the Game Commission’s independent scientific advisers who monitor the state’s bird populations? Should they be privy to the mortality rate at Pennsylvania’s proliferating wind turbines?

The group certainly thinks so, but the body count is not shared with them, either.

Instead, the Game Commission, apparently to gain turbine owners’ participation, agree to share information with each other but not anyone else.

The agreement states, “It is understood between the parties that information resulting from the cooperator’s compliance with this agreement shall be treated with the highest affordable level of confidentiality available unless otherwise agreed to in writing by both parties.”

When I requested the results of dead bird searches at the Turkey Hill project, PPL said it “was following the Game Commission’s protocol in keeping it in confidence.”

This is the questionable state of affairs several years into wind energy taking hold in Pennsylvania.

The Game Commission is responsible for the state’s birds and mammals.

As wind technology advanced like a sudden gust of wind several years ago, it became clear there were no comprehensive regulations in place to protect wildlife.

Working with energy companies — and at least initially independent advisers such as the PBS — the Game Commission fashioned a voluntary agreement designed to avoid, minimize and mitigate impacts on wild animals.

Mainly, we’re talking about birds, and especially bats, which seem to be most prone to running into turbine blades.

Since 2007, 73 percent of the owners of wind projects in the state have signed the Wind Energy Voluntary Cooperation Agreement.

Among the notable exceptions is Florida Power & Light and its subsidiaries, which have the most turbines in the state. High bat mortality has been found at some of them.

In addition to working with the Game Commission to reduce effects on birds, wind companies agree to do pre-construction surveys of birds and animals at proposed sites, and to count any mortality from turbines for two years after startup.

That advance scouting of bird habits and pooling of information has been effective, according to the Game Commission.

Turbines have been moved, bat-roosting locations have been pinpointed and protected, and even a few turbine sites have been abandoned, the agency says.

Indeed, at Turkey Hill, the number of turbines was reduced from four to two, the two turbines that were built were set back farther from the Susquehanna, vegetation is kept close-cropped so as not to attract predators and electrical lines were buried to discourage perching birds near the turbines — all because of pre-construction wildlife surveys, points out Steven Gabrielle of PPL.

“We’re not required to do this. We’re spending a lot of time and money to do this because we respect preserving the environment,” Gabrielle says.

Then why not prove it by making available the results of all those commendable approaches, I say.

Another who is very unhappy with the no-tell approach is George Gannon, a professor of biology and ecology at Penn State-Altoona who worked with the Game Commission in setting up the wind energy cooperative agreement on behalf of the PBS.

He voices this complaint, “There is no independent scientific peer review of anything submitted by the wind companies, as these data are not permitted to be seen by anyone else.

“This is contrary to the very basic premise of how good science works.”

He mentions a 2009 case in West Virginia where a federal court found that a wind company’s hired bat consultants reached a conclusion favorable to the client, but turned out to be inaccurate when the actual data was reviewed.

“It was Ronald Reagan who said ‘trust but verify,’ ” continues Gannon. “Unfortunately, with the system in place, the PGC cannot verify the work submitted by wind developers and the people of Pennsylvania cannot verify either the developers or the PGC.”

In 2007, a PBS wind energy and bats subcommittee accused the Game Commission of “side-stepping” input and review from the PBS in developing the cooperative agreement with wind energy developers.

The group, which included two PGC biologists, unanimously urged the agency to abandon the protocol used in evaluating bats and bat mortality at wind turbine sites and to “develop a more realistic, more meaningful, and more scientifically sound protocol.”

The current agreement “puts the interests of the wind industry before the interests of the Commonwealth,” the PBS group said.

The Game Commission recently issued its second wind energy summary report that includes 150 wildlife surveys and research under the voluntary agreement from 2007 through June 30, 2010.

Among the tidbits (no names, of course):

The number of bat deaths comes out to 24.6 per turbine per year.

Among birds, the average death rate was 3.9 per turbine per year.

Three state-endangered birds were killed: two blackpoll warblers and one yellow-bellied flycatcher. All three were deemed to be migrants passing through and not from local breeding populations.

No large mortality events were recorded, defined as more than 50 carcasses found in a single day.

Surveys conducted as part of the agreement have located new locations of state- and federally-listed bats.

As part of the cooperative agreement, the Game Commission has said it will not pursue liability against cooperating wind turbine companies that kill birds, as long as they comply with the conditions of the agreement.

The agency is proud of its efforts.

“The Cooperative Agreement has allowed Pennsylvania to become one of the national leaders for determining and addressing wildlife impacts from wind energy development, as well as providing critical data needed to address future wind energy project proposals,” said William Capouillez, director of the agency’s Bureau of Wildlife Habitat Management.

With some transparency on behalf of the Game Commission and wind turbine operators, maybe the public would come to the same conclusion.

IBERDROLA SAYS FALLING SUZILON BLADES WERE A ONE-TIME ACCIDENT

By Natalie Obiko Pearson,

Iberdrola SA (IBE), the world’s biggest renewable energy producer, has found that falling blades from a Suzlon Energy Ltd. (SUEL) generator at a U.S. wind farm was a one-off accident unrelated to the turbine’s history of cracked blades.

“This type of failure is a singular event,” said an Iberdrola report, a copy of which was mailed by Suzlon to Bloomberg News, on a joint investigation by the two companies into the incident.

Iberdrola suspended operations at the 150-megawatt wind farm in Rugby, North Dakota after blades from a Suzlon S88 turbine fell from their mount, the company said on March 21. The same model suffered cracked blades starting in 2007, which had prompted a $100 million global retrofit program by India’s largest maker of windmills for power production.

The accident at Rugby was caused by the failure of a bolt connecting the rotor assembly to the nacelle, the report said. Stress may have been put on the bolt because of a misalignment of the connecting surfaces between the rotor hub and mainshaft flange, it said.

All 70 turbines and 3,360 bolts were inspected and seven bolts replaced as a precaution before Iberdrola and Suzlon agreed the site was safe to return to service, it said.

“Suzlon, who is permanently onsite, will perform additional checks in conjunction with regular maintenance activities,” it said.

Suzlon has more than 2,000 sets of S88 turbines operating worldwide and its global fleet are performing above industry standards, spending only 3 percent in downtime for maintenance, the company said in an e-mail.

Suzlon shares plummeted 83 percent between the time it announced the defect in January 2008 and completed retrofitting in October 2009 as customers, including Rosemead, California- based Edison International (EIX), canceled orders.
