Better Plan, Wisconsin

 

NOTE FROM THE BPWI RESEARCH NERD:

WISCONSINS DIRTY GREEN SECRET: The most recent post construction mortality studies confirm that Wisconsin's wind turbine related bat-kill rate is the highest in North America and is considered to be unsustainable.

Aside from a single article by Tony Walter in the Green Bay Press Gazette, the media has been silent on this issue. (The article by Tony Walter is no longer available on the Press Gazette website (why?) but you can read it HERE.)

State and local environmental groups are taking a strict hands-off approach to this subject and have not spoken out, allowing the slaughter to continue with no complaint.

If you are a member of a Wisconsin environmental group, please urge them to look into this issue and speak up.

HOW BAD IS IT?

Wind developers claim turbine related bat mortality will cause about four deaths per turbine per year.

Pennsylvania is making headlines with a bat kill rate of 25 kills per turbine per year.

In Wisconsin, the most recent post construction mortality study puts the kill rate at over fifty bats per turbine per year.

Larry Roberts/Post-Gazette

Suzanne B. McLaren, the collection manager in the Carnegie Museum of Natural History's section of mammals, extends the wing of an approximately 3-inch specimen of a Seminole bat, rare in Pennsylvania, which was reportedly killed in the vicinity of a wind turbine.

The butterfly effect suggests the flapping of a tiny insect's wings in Africa can lead to a tornado in Kansas.

Call this the bat effect: A bat killed by a wind turbine in Somerset can lead to higher tomato prices at the Wichita farmers market.

Bats are something of a one-species stimulus program for farmers, every year gobbling up millions of bugs that could ruin a harvest. But the same biology that allows the winged creatures to sweep the night sky for fine dining also has made them susceptible to one of Pennsylvania's fastest-growing energy tools.

The 420 wind turbines now in use across Pennsylvania killed more than 10,000 bats last year -- mostly in the late summer months, according to the state Game Commission. That's an average of 25 bats per turbine per year, and the Nature Conservancy predicts as many as 2,900 turbines will be set up across the state by 2030.

This is a bad time to be a bat.

It may seem like a good thing to those who fear the flying mammals, but the wind farm mortality rate is an acute example of how harnessing natural energy can lead to disruptions in the circle of life -- and the cycle of business. This chain of events mixes biology and economics: Bat populations go down, bug populations go up and farmers are left with the bill for more pesticide and crops (which accounts for those pricey tomatoes in Kansas).

Wind industry executives are shelling out millions of dollars on possible solutions that don't ruin their bottom line, even as wind farms in the area are collaborating with the state Game Commission to work carcass-combing into daily operations.

"If you look at a map and see where the mountains are, everything funnels through Somerset," said Tracey Librandi Mumma, the wildlife biologist who led the March commission report on bird and bat mortality. "If I'm out driving ... I wonder, 'How many are being killed at that one?' "

Bats are nature's pesticide, consuming as many as 500 insects in one hour, or nearly 3,000 insects in one night, said Miguel Saviroff, the agricultural financial manager at the Penn State Cooperative Extension in Somerset County.

"A colony of just 100 little brown bats may consume a quarter of a million mosquitoes and other small insects in a night," he said. "That benefits neighbors and reduces the insect problem with crops."

If one turbine kills 25 bats in a year, that means one turbine accounted for about 17 million uneaten bugs in 2010.

Bats save farmers a lot of money: About $74 per acre, according to an April report in Science magazine that calculated the economic value of bats on a county-by-county basis.

In Allegheny County, bats save farmers an estimated $642,986 in a year. That's nothing compared with more agricultural counties in the region such as Somerset ($6.7 million saved), Washington ($5.5 million) or Westmoreland ($6.1 million).

Lancaster County? You owe bats $22 million.

In all of Pennsylvania, bats saved farmers $277.9 million in estimated avoided costs.

Initially, the "Economic Importance of Bats in Agriculture" article was meant to attract attention to the white-nose fungus virus that is wiping out entire colonies of bats across the country.

"We were getting a lot of questions about why we should care about white-nose syndrome," said author Justin Boyles, a post-doctoral fellow in bat research at the University of Tennessee. "Really, it's the economic impact that makes people listen."

The white-nose syndrome is compounding the wind turbine problems, having killed more than a million bats in the northeastern United States since 2006. It surfaced in Pennsylvania in 2008 and has killed thousands of in-state bats.

Meanwhile, the same creatures that save Pennsylvania farmers millions of dollars each year are also costing energy companies some big bucks as they try to stave off a mass execution beneath the blades.

Technology is being developed on sound generators that would deter the creatures from getting too close with a high-pitched noise only heard by bats. Some studies suggest that a slowdown in blade speed would reduce mortality.

But new technology is expensive and a blade slowdown would reduce the number of megawatts produced.

"All these options cost money," said Ms. Librandi Mumma, and it can be a tough sell to the private industry handing over the information that helps in the research. "You don't want to penalize the hand that's giving you the data."

Companies that have signed a Game Commission cooperation agreement must foot the bill for the commission's pre-construction reconnaissance and post-construction monitoring. The cost of the process varies, but the research can last several months and involve extensive habitat monitoring.

Under the agreement, each site conducts two years of mortality monitoring, sending a lucky employee out every day from April to November to comb the six meters around each turbine for carcasses. The employees are tested to see "how good they are at finding dead things," said Ms. Librandi Mumma.

"We got a dead snake once, because it was on the road and they were just collecting everything dead," she said. "It wasn't because the wind turbine killed it. The guy was just being thorough."

Some retrievers aren't so good.

"The average person finds 30 percent of the carcasses that are under a turbine," said Ms. Librandi Mumma, so the commission has come up with an algorithm that accounts for the missing bodies.

Agents will leave a carcass on the ground and note how long it takes to disappear -- this provides some insight on how many carcasses are unaccounted for because of living animals that have a taste for decomposing flesh.

Some wind companies with Pennsylvania operations have already seen seven-figure expenses on account of the bat problem.

NextEra Energy Resources, which operates the Somerset wind farms visible from the Pennsylvania Turnpike, has five active sites in Pennsylvania but did not participate in the Game Commission study.

The company monitors its mortality rates in house and funds outside research to reduce bird and bat deaths at its sites, said Skelly Holmbeck, environmental business manager at the Juno Beach, Fla.-based firm.

The funding program involving nine different research facilities is "in the millions overall," she said.

Migratory research that precedes any construction can employ bird watchers, nets or tape recorders designed to read the local ecosystem.

PPL Renewable Energy LLC of Allentown had planned on installing four turbines at its Lancaster County wind farm, but went with only two after sensitive avian populations were found nearby.

"There were design aspects that we elected not to use," said spokeswoman Mimi Mylin. "Some construction sites use lattice towers, but those can become roosting sites" for birds.

It's not just bats that are dying around wind turbines. An estimated 1,680 birds were killed by turbines last year, according to the state Game Commission report.

The disparity in mortality stems from biology. Birds typically crash into the blade and die from blunt force trauma, while bats suffer from a condition called barotrauma. It's the bat equivalent of the "bends" that scuba divers can suffer if they surface too quickly.

The rapid drop in air pressure around the blades causes the bats' lungs to burst, and they collapse with no ostensible lacerations or scars on the body.

"They just look like they're sleeping," said Ms. Librandi Mumma.

Bats must fly very close to the blades for their lungs to burst, and some researchers say the lights around the turbines might attract insects, which in turn attract bats.

Barotrauma in bats was only discovered in 2008, when a Canadian biologist thought to dissect one of the unblemished carcasses turning up at wind farms across North America.

"It was an 'a-ha' moment," said Ms. Librandi Mumma.

The turbine problem has yielded some other, unexpected contributions to bat research.

One carcass hunter in central Pennsylvania found a Seminole bat felled by barotrauma under the blades. Seminole bats live in the southeastern United States and rarely show up in Pennsylvania.

"It's like a double-edged sword," said Ms. Librandi Mumma. "You're excited because it's a new bat, but it's a dead one."

The Seminole specimen was kept on dry ice in a small styrofoam container by a commission employee and handed over to Suzanne McLaren, the collection manager at the Carnegie Museum of Natural History's research center in East Liberty. They met in the Ligonier Diamond town square -- home to a postcard-perfect gazebo and lots of sunlight -- for the transfer.

The bat, which may have traveled here from as far as Florida, found its final resting place in a freezer in East Liberty.

HEALTH REVIEW PROMISED INTO WIND FARMS

“I’m standing here because there is a problem,” Ms Bernie Janssen told the seminar. Ms Janssen says she didn’t object to the wind farm at Waubra, in Victoria in 2009, until she began feeling unwell.

“In May-June 2009 I woke in the night with rapid heartbeat, shortness of breath. I didn’t associate it then with wind turbines. In July, my GP noticed that my blood pressure was elevated.” She says she’s also felt body vibration, hypertension, tinitus, cognitive depression, sleep disruption, ear and head pressure.

She found out 37 people living up to 4km away from turbines began experiencing symptoms at about the same time.

The NHMRC’s hearing comes just one week before the Senate Inquiry in the impacts of windfarms is tabled in Parliament.

Many studies on so called wind turbine syndrome have been based on interviewing sufferers.But a Portugese environmental scientist is studying the physical effects of low frequency noise on the body. Dr Mariana Alves-Pereira of Lusofona University in Portugal has been studying vibroacoustics.

“We assess the effects of noise based on medical tests, so they’re objective medical tests. If we go in what we’ll do is get echo-cardiograms, we’ll do brain studies.”

Dr Alves Pereira has degrees in physics, biomedical engineering and a phD environmental science. She bases her research on her earlier work on aircraft workers, dating back to the 1980s who’ve been exposed to high levels of noise, up to 200Hz. “Noise in the aeronautical industry is very rich in low frequency components,” she says.

She found a specific set of symptoms associated with people exposed to low frequency noise, but says these levels are much lower than the levels of low frequency noise in houses near windfarms. She says they studied one family and their horses near a windfarm, and the biological response of their tissues which she says relates to exposure to low frequency noise.

UK based noise and vibration consultant Dr Geoff Leventhall says the media has been running scare stories about infrasound since the 1970s. He cites NASA’s research with Apollo space program found no impact.“The sort of energy exposure from the NASA work over 24 years would take a few thousand years to get from wind farms at the low levels that they have.”

He rejects the theory of a direct physiological effect of infrasound, he says it’s an assumption. He says what annoys people is the audible swish of the blades not infrasound.

Renowned anti-smoking campaigner, public health Professor Dr Simon Chapman has entered the debate and says it’s a noisy minority who say they suffer from the noise. Dr Chapman argues compensation from wind turbines situated on your farm could be the antitode. “People who move to the country, often will feel don’t want their environment disturbed.. and they’re annoyed to see wind farms unless they’re benefitting economically from them.”

He doesn’t see the need for more research, because it might hold up development of wind power. Despite the scepticism, Australia’s peak body supporting health research the NHMRC will conduct another review of the evidence over the next 12 months.

TURBINE TALK: NEW STATE PANEL TO STUDY HEALTH EFFECTS

READ THE ENTIRE STORY AT THE SOURCE: FALMOUTH BULLETIN, www.wickedlocal.com

June 8 2011

By Craig Salters

Terri Drummey told the crowd that her son refuses to sleep in his bed because of the “thumping” and was having problems at school until the turbine was curtailed.

Falmouth selectmen organized a Monday night forum to discuss the issue of wind turbines and received a standing-room-only crowd of state and local officials, expert consultants and mostly angry residents.

Discussions of noise, low frequency noise, shadow flicker, proper setback distances and possible health effects from the turbines dominated during the more than three-hour meeting.

The final portion of the meeting was reserved for the comments of abutters to the town’s Wind 1 turbine at the Falmouth Wastewater Treatment Facility. Those residents shared stories of sleepless nights, headaches and other ill effects they say are brought on by the turbine.

Regardless of this or that study, they told the board, there is a problem with the nearly 400-foot, 1.65-megawatt turbine, which has been operational for more than a year but is now curtailed during strong winds in a nod to residents.

“Clearly there is a problem. We are not complaining just to complain,” Blacksmith Shop Road resident Dick Nugent told selectmen after pointing to the packed auditorium at the Morse Pond School. “We don’t expect you to have all the answers but we do expect you to take it and run with it.”

The entire auditorium received a bit of news early in the meeting when Steven Clarke, assistant secretary at the state’s Executive Office of Energy and Environmental Affairs, announced that a panel will be formed this week to specifically study any health effects regarding the sounds from wind turbines. That panel will be comprised of representatives of the state’s Department of Environmental Protection and its Department of Public Health.

“Right now, the focus is on sound,” Clarke told the audience.

Regarding possible health effects, Gail Harkness, chairwoman of the Falmouth Board of Health, said that board has been meeting with concerned residents for the past year and now receives bi-weekly updates at its regular meetings She said reported health effects include sleep disturbances, fatigue, headaches and nausea. The board has created a database of information on the issue and has also developed a wind turbine complaint and/or comment form which will be available online.

Patricia Kerfoot, chairwoman of the planning board, lauded the town for its decision to have a one-year moratorium on new wind turbine projects while more information is collected and regulations are formulated. “First and foremost, the planning board is here to listen,” Kerfoot said.

Kerfoot and others had plenty to listen to. There was Chris Menge of Harris Miller Miller & Hanson, the project manager of a noise study on the Wind 1 turbine. He discussed the results of the analysis including additional clarifications requested by the state. According to Menge, Wind 1 did not exceed noise limits but there would be trouble between midnight and 4 a.m. after Wind 2 goes into service. He recommended shutting down one of those turbines at low wind speeds during those hours.

But there was also Todd Drummey, an abutter, who used data available from the studies to point to different conclusions. Drummey said Menge’s claim that the turbine is less intrusive at high wind speeds is contrary to the experience of residents.

“The wind turbine is annoying at low speeds,” Drummey said. “It’s intolerable at high speeds. It drives people out of their homes.”

Drummey was joined by Mike Bahtiarian of Noise Control Engineering, a consultant hired by the resident group. His major point was that amplitude modulation, or what he called “the swishing” of the turbines, needs to be considered.

Stephen Wiehe, a representative of Weston & Samson, discussed the financial aspects of the municipal turbines while Thomas Mills and Susan Innis, both of Vestas, discussed the mechanical details of the turbine itself.

Malcolm Donald, an abutter from Ambleside Drive, discussed the concerns of turbine malfunction and the potential of ice being thrown from the blades. However, probably his most compelling testimony concerned “shadow flicker,” which is the rhythmic flashing of sunlight and shadow caused by the spinning blades. He showed the audience a video shot from inside his house where, looking through the window, the shadow of the blades can be seen moving repeatedly across his lawn.

“The inside of the house looks like a disco in the morning,” he said.

Terri Drummey told the crowd that her son refuses to sleep in his bed because of the “thumping” and was having problems at school until the turbine was curtailed.

“He’s happily brought his C’s and D’s up to A’s and B’s within days,” said Drummey. “Let me repeat that: within days.”

Falmouth selectmen have scheduled a July 11 meeting to follow up on further discussion of the turbines.

Selectmen Chairwoman Mary Pat Flynn thanked everyone for attending the forum but singled out residents for sharing their experiences.

“Certainly they were very personal and right to the point,” she said.

"Terri Drummey referred to the turbine issues as “the so-called Falmouth Effect,” and described the difficulty sleeping and concentrating which she said had led to her 10-year-old son’s declining grades, as well as her daughter’s headaches, and the ringing in her husband’s ears.

“We are the unwilling guinea pigs in your experiment with wind energy,” she said.

ST. PAUL — Two wind companies with plans to build wind farm projects in Goodhue County shelled out $480,000 in lobbying expenditures in 2010, according to a new report.

AWA Goodhue, which has proposed a 78-megawatt project, spent $380,000 on lobbying. That company ranked 17th highest when it came to lobbying expenditures in 2010, according to the report released by the Minnesota Campaign Finance and Public Disclosure Board. Geronimo Wind, which is also looking at installing turbines in Goodhue County, spent $100,000.

Zumbrota Township resident Kristi Rosenquist, who opposes the wind project, said she was “shocked” when she saw how much AWA Goodhue spent on lobbying.

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

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.

FROM NORTH DAKOTA

IBERDROLA SAYS FALLING SUZILON BLADES WERE A ONE-TIME ACCIDENT

READ THE WHOLE STORY AT THE SOURCE: Bloomberg, www.bloomberg.com

May 18, 2011

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.

WIND GENERATORS STILL CAUSING PROBLEMS

SOURCE Fond du Lac Reporter, www.fdlreporter.com

April 14, 2011

I live about 2,100 feet from a wind generator and had experienced interference on my television as soon as it went into operation.

Cedar Ridge Wind Farm made arrangements to remedy the interference. I was given two years of basic Satellite TV service at no cost.

Then, I received a notice that Alliant, owners of the wind farm, had decided to grant us compensation equal to the cost of getting only the Green Bay local channels. All I needed to do was to sign a “Release of Claim,” which states in part “the undersigned… hereby fully and forever releases and discharges Wisconsin Power and Light … from any and all claims, demands, actions and/or rights … arising from…”

The three paragraphs protect Alliant forever in every way from any future actions. There is no mention of what we might expect in the coming years.

Does this sound like a good faith effort to correct a wrong done to those of us who have no commercial interest in the wind farms?

Feeling put upon by Alliant following both written and oral communications with their representative, last February I proceeded to contact my local Assembly representative, Richard Spanbauer. I received a letter from him stating, “The Joint Rules Committee recently held a public hearing about the proposed rules changes.”

He offered no suggestions regarding the restraints Alliant is imposing upon us.

Sensing that I might get a better response from our native son, U.S. Rep. Tom Petri, I delivered copies of all correspondence to his office in Fond du Lac. No response. I sent an email to him reminding him of my concern. No response.

I suppose my next attempt at obtaining fair treatment from Alliant would be to file a class action. Why must it come to that?

FOREST RESIDENTS CONTINUE FEUD OVER WIND TURBINES

SOURCE: Pierce County Herald, www.piercecountyherald.com

April 14, 2011

Jeff Holmquist

The Town of Forest has been a quiet, rural community for much of its long history. But these days there is an atmosphere of unrest throughout the township, thanks in part to a proposed wind farm proposal that has been debated over the past couple years.

Supporters of the wind energy idea and opponents have been feuding over an agreement with Emerging Energies LLC to place up to 39 wind turbines on private properties. The agreement would pay landowners and residents within a half mile of each turbine an annual payment. The township and county would also have received annual payments.

“Residents and landowners are either for or against this,” said Jaime Junker, newly elected town board chairman. “There really is no in between ground. The division line is fairly well divided between people who would get compensated by the project and those who would not.”

Emerging Energies has been studying wind speeds in the St. Croix County township for more than two years. The Forest area was found to be a favorable location for large wind turbines due to sustained winds in the area.

The company’s research shows that average wind speeds are about 16 to 17 mph, which is sufficient to turn a large turbine and thus generate electricity.

According to the original plans, the turbine system would have been hooked up to a new or existing electric substation and the power would have ended up on the grid.

While there was support for the idea among some residents and the Forest Town Board during the initial planning stages, a number of residents are less than happy with the project.

A citizens group, called the “Forest Voice,” formed in an attempt to stop the project from moving forward.

The group filed a federal lawsuit on Feb. 9, 2011, claiming that the Town Board had bypassed open meeting law requirements to push through an agreement with Emerging Energies. The group also claimed that several board members should not have participated in the vote for the wind farm plan as they or their relatives stood to gain financially from the project.

The disgruntled Town of Forest residents also petitioned for a recall election of the former town board members. All of the challengers eventually won election to the board. The support of the majority of the residents was reaffirmed last Tuesday when wind turbine opponent Jaime Junker was re-elected as town chairman, and newly elected Patrick Scepurek and Richard Steinberger were returned to their supervisor positions.

After gaining office, the new board members voted on March 17 to rescind the wind energy development agreements, driveway permits and other approvals that had been granted to a wind developer. The board also approved a temporary stay on the location and construction of the turbines in the township.

According Forest Voice’s Attorney Glenn Stoddard, most Town of Forest residents were “completely unaware” that the former town board members had approved an agreement in 2008 and another one on Aug. 12, 2010, to proceed with the proposed wind energy project.

A postcard announcing the project was the first many heard about the plan, he claimed.

No public hearing was ever held by the defendants during a three-year development period, he further claimed.

The opponents of the wind project allege that the proposed wind energy project would destroy their quality of life and have adverse health and safety impacts on them.

Despite the fact that the agreements have been rescinded and the town board has been replaced, Stoddard said the federal lawsuit is likely to continue. He said Emerging Energies has indicated that it may seek legal action in an effort to continue with the previously approved project.

Officials with Emerging Energies did not want to comment on the Forest project when contacted.

Junker said many expect the company to seek a legal opinion in the matter.

“Now it’s pretty much a wait and see situation,” he said. “It’s hard to predict what the short term future is going to be.”

Whatever the future holds, residents on both sides of the issue say they are frustrated by the continuing feud over wind turbines.

“What has happened in our township is heartbreaking and has left many residents feeling betrayed,” said Brenda Salseg, a property owner and managing member of the Forest Voice LLC.

“Those of us who researched industrial wind turbines found disturbing evidence of health, safety and property devaluation issues associated with so-called wind farms when turbines are sited too close to homes. It’s all about what is profitable rather than responsible, which is what I thought green energy is supposed to be.”

Salseg said it’s unfair to force wind turbine opponents to live near such a large project.

“The statement we continually hear that wind energy is green, clean and renewable is nothing more than deception,” she said.

Gary Heinbuch, who continues to be a supporter of the wind project, said the atmosphere in Forest is now “as foul as can be.”

“It’s neighbor against neighbor. It’s niece against uncle,” he said. “I never thought it would get this bad.”

Rick Heibel, 53, who signed an agreement to have three turbines sited on his 240 acres, agreed.

“It’s gotten way more heated than I ever thought it would,” he said. “I never thought it would get this divisive.”

Heibel, who has lived his entire life on the farm that was first settled by his grandfather 99 years ago, said he remains convinced that the wind project would be good for him and for the town.

The annual payments to landowners and local units of government would mean a lot, he said.

“It would greatly enhance my retirement,” Heibel said. “Right now, my retirement is Social Security. All my savings is in my land, and I don’t want to sell my land. It would make my standard of living more comfortable.”

Apart from the financial benefits, Heibel said wind generation just makes sense.

He said all energy generation methods have their drawbacks. The burning of coal contributes to global warming and the mining of coal harms the land, he noted. With the ongoing disaster in Japan, Heibel wonders if more nuclear plants are a good idea. Even natural gas has its problems, he added.

“With wind, I think it’s one of the least damaging forms of generation as far as the environment goes,” he said.

BPA, WIND DEVELOPERS ARGUE OVER LOOMING PROBLEM OF TOO MUCH POWER FROM RENEWABLES

SOURCE: The Oregonian, www.oregonlive.com

April 14 2011

By Ted Sickinger,

Under pressure from wind developers and investor-owned utilities around the region, the Bonneville Power Administration this week backed away from a plan to start pulling the plug on wind turbines when it has too much water and wind energy at the same time.

BPA Administrator Steve Wright is still reviewing a controversial plan to occasionally “curtail” wind farms in the region, a move the federal power-marketing agency has said is necessary to maintain grid reliability, protect migrating salmon and avoid passing big costs onto its public utility customers.

Wind developers and utilities who buy their output say such shutdowns are discriminatory, will breach transmission agreements and compromise wind-farm economics because the projects rely on lucrative production tax credits and the sale of renewable energy credits that are generated only when turbine blades are spinning.

They also maintain the plan is simply unnecessary, a sop to public utility customers that can be solved by other means.

In one sense, the debate is simply the latest wrinkle in the perennial debate over who should bear the costs and benefits of operating the federal hydroelectric dams and transmission system. But it illustrates the growing complexity of integrating into the grid intermittent sources of renewable energy.

“This is going to be a major issue for the region,” said John Saven, chief executive of the Northwest Requirements Utilities, a trade group representing 50 public utilities that buy their power from the BPA. “We’re in the first inning.”

The capacity of wind farms connected to the BPA’s transmission network has ballooned from 250 megawatts in 2005 to more than 3,500 today and is expected to double again in the next two years. That outstrips demand growth in the region and is being driven in large part by California utilities, which are required to meet a third of their customers’ electricity needs with renewables by 2020.

Oregon and Washington have their own mandates, but more than half the wind power generated in the Northwest is sold under long-term contact to California. Congested transmission often means the only things exported are the associated renewable energy certificates that buyers use to comply with state mandates. The electricity often stays in the region, dumped into this region’s wholesale market, depressing prices for electricity from all sources.

Grid balance

The BPA, which operates 75 percent of the high-voltage transmission grid in the region, is responsible for balancing the minute-to-minute variations in supply and demand on the grid. The agency says growing wind capacity requires it to reserve more of its hydro generation as backup reserves, either to fill in for scheduled electricity when the wind isn’t blowing or back off hydro production when wind-farm output is higher than scheduled.

The BPA charges wind farms for that flexibility. But it says there’s only so much it can absorb before those reserves start to compromise regular operations.

Overgeneration typically occurs in the spring and early summer, when snow runoff and heavy rains combine to increase hydro generation and the same storm fronts rapidly ramp wind turbines. The BPA says the dam operators have only limited flexibility to dial back hydro generation to accommodate wind surges because dumping water through the dams’ spillways raises dissolved nitrogen levels in the river, which can harm migrating fish.

The result, BPA officials say, is that the agency is left with more power than regional customers need or that an already congested transmission system can ship out of the region.

“Eventually, you just run out of places to put it,” said Doug Johnson, a BPA spokesman.

Long-term fixes

The BPA has worked during the past two years — some say been pushed and dragged — to accommodate more wind by improving forecasting and transmission scheduling. Adding transmission or new storage is a potential solution, as is transferring the responsibility for balancing some of the variable supply and demand to other utilities. But those are expensive, long-term fixes.

Meanwhile, new wind farms keep mushrooming on the Columbia Plateau, exacerbating the problem. Last June, high wind and water nearly forced the BPA into “negative pricing,” when it is forced to pay utilities and independent power producers in the region to shut down their plants and take BPA power instead.

That’s expensive for wind farms, where the cost of curtailment is not just replacement power, but the loss of production tax credits and renewable energy tags they generate when operating. The BPA recently estimated the combined impact at $37 a megawatt hour.

That’s not a price the BPA or its public utility customers want to pay.

Wind producers are the Johnnys-come-lately to the Northwest’s energy scene. But they argue that any move to single them out and curtail their production is discriminatory and violates the equal-access provisions of the laws governing the federal transmission system.

They have the support of Oregon’s Rep. Earl Blumenauer and Sen. Jeff Merkley, two Democrats who have criticized the agency in the past for dragging its feet on wind issues.

The BPA has backed away from formally implementing the wind-curtailment plan, a move that renewables advocates applauded. But it hasn’t come up with an alternative.

BIRDS & BATS VS BLADES

SOURCE: Prince George Free Press, www.bclocalnews.com

April 14 2011

By Allan Wishart -

What happens when a bird or a bat gets involved with a wind turbine?

It’s not usually a good result for the animal, UNBC instructor Ken Otter told a Cafe Scientifique audience at Cafe Voltaire on Wednesday evening.

Otter, an instructor in the ecosystem science and management program, said people have been researching the idea that wind farms and birds have a collision problem.

“Most research suggests the problem is not much worse than with other tall structures, such as high-rise buildings or radio towers,” he said in an interview with the Free Press, “but certain species seem at a higher risk.”

Most of the at-risk species are migratory birds, which may encounter the turbines on their regular route, and “soaring” birds.

“These are species which make use of a lot of updrafts when they’re flying, birds like hawks or eagles and cranes.”

With the wind-farm technology still relatively new in Canada, the opportunity is there to work with industry to make it as safe as possible for the animals, he said.

“What we’re finding s it doesn’t take much to make the farms safer for birds. A lot of it is looking at weather patterns.”

Generally, he said, the birds are flying at elevations well above the turbines. Sometimes, however, a weather pattern will push them lower, to where they may be at risk.

“We can plot out the tracks of their migrations and see how they use the ridges and rises. That allows us to predict where the patterns will occur, and we can get very specific information.”

How specific? Otter says in some cases it could be a question of just idling one turbine in a group for a few minutes to allow a flock of birds to get by.

“Most of the turbines can be idled in about two minutes. It might just be a question of having someone out there to keep an eye on the conditions and, if needed, call back to the main operation and ask them to shut one of the turbines down for a few minutes.”

Otter said a University of Calgary study found bats ran into a different problem when it came to wind turbines.

“They have very thin walls in their lungs, and a lot of capillaries to distribute the blood. the study found groups of sometimes hundreds of bats dead near a turbine, but with no contusions on their body to indicate they had been hit by one of the vanes.”

Autopsies showed the capillaries had burst inside the bats. This led researchers to take a look at how the turbines affected wind pressure in their area.

“What happens with any fan is there is a low-pressure area created right behind the vanes. The bats were coming into this area, and their capillaries were bursting because of the sudden drop in pressure.”

Again, the solution may be as simple as varying the speed the vanes turn at to ease the drop in pressure.

And, he says, the industry seems to be willing to look at making these changes.

“We’re working with them, showing them how these small changes can keep the birds and bats safe, and they’re listening.”

WIND FARMS AND DEADLY SKIES: TURBINES ON TEXAS COAST KILLING  THOUSANDS OF BIRDS AND BATS EACH YEAR

SOURCE: San Antonio Express-News, www.mysanantonio.com

February 27, 2011

By Colin McDonald,

SARITA — The 260-foot-tall wind turbines of the Kenedy Ranch stand like a steel forest along the edge of the Laguna Madre and pump out hundreds of megawatts of emission-free electricity.

The spinning blades, alongside some of the most important habitat in Texas and one of North America’s largest migratory flyways, are killing thousands of birds and bats each year.

How many isn’t publicly known because, unlike California counties, Texas and the federal government don’t require turbine operators to make public reports, according to state and federal officials.

Aside from the quantity of bird and bat deaths, a more complicated question remains unanswered as more wind turbines are put up along the Texas Coast: Have the turbines changed the ecosystem and displaced wildlife?

For the first time, Pattern Energy, which owns 118 turbines on the ranch, and Iberdrola Renewables, which owns 168, voluntarily released results of their first yearlong studies.

Pattern estimates up to 921 birds and 2,309 bats were killed between Aug. 24, 2009, and July 31; Iberdrola’s estimates: 1,812 birds and 3,087 bats for the same period.

While the bird killings match the national average, one researcher found the bat killings much higher than expected.

Those who opposed the wind farms are not convinced the studies are credible or conclusive.

The work was paid for by the companies and not peer-reviewed. In their reports, biologists wrote about the challenges of collecting good data with rattlesnakes biting their search dogs and cows that would not leave. The researchers estimate scavengers removed half of the bird and bat carcasses before they could be found.

They also could not get federal permits to collect the species they did find, so many had to be marked as unknown.

After more than a year of submitting forms, the companies received a collection permit last month, said Rick Greiner of Pattern Energy.

But of the species identified, none were endangered.

“We think there is a low impact to T and E (threatened and endangered species) because we have not found any,” he said.

The reports state the wind farms had a bird mortality rate of three birds per megawatt, which is in the middle for the national average of one to six birds, according to the American Wind Energy Association, a trade group. A national average for bats killed per megawatt is not well-established.

In addition to average bird mortality, the companies point to the high-tech radar systems they voluntarily installed that will trigger a shutdown of the spinning turbines during fog or low visibility when a mass of birds or bats is approaching.

As of the end of 2010, a shutdown had not occurred.

“At every stage of the project’s life, Iberdrola Renewables has gone above and beyond what has been required by the state of Texas and federal government to conduct extensive studies and monitor the outcomes of our wildlife protection measures,” said Jan Johnson, a spokeswoman for Iberdrola.

More than numbers

One who disagrees the studies have been extensive is David Newstead, an environmental scientist for the Coastal Bend Bays & Estuaries Program in Corpus Christi and president of the Coastal Bend Audubon Society.

He believes mortality rates are an incomplete measurement of the effect of wind farms. The numbers do not reflect how turbines could be changing behavior of birds and bats by forcing them out of their habitat and putting them under greater stress.

“Cumulative effects are practically never discussed by wind developers,” Newstead said. “At the end of the day, the most important numbers, for the sake of the wildlife, is how many of what species of birds and bats are being not only killed, but displaced.”

Newstead is one of most vocal challengers to the construction of wind farms along the Texas Coast and was part of an unsuccessful lawsuit to stop them, funded in large part by the King Ranch, which borders the Kenedy Ranch.

“There is no other place in North America that plays such an important role for so many species during some part of their lives,” Newstead said about the Laguna Madre and surrounding grasslands. “Collision mortality can thus affect any of more than 400 regularly occurring species.”

Newstead’s concerns for the coast only grow as more turbines are built, following the lead of the Kenedy Ranch.

Since the Kenedy turbines came online in 2009, Iberdrola has added more, and the Papalote Creek Wind Farm with 196 units was built outside Corpus Christi, according to AWEA.

When operating at capacity, the Kenedy Ranch turbines in total can generate close to 680 megawatts, or enough electricity to meet the needs of 135,000 to 170,000 homes, according to CPS Energy, which buys power from Iberdrola.

That power is produced during the day when consumer demand is the highest, and it can be delivered via uncongested transmissions lines, said CPS Energy spokeswoman Lisa Lewis, adding that effect on wildlife was not considered when it signed the contract.

Working with wind

For now, wind companies face few consequences for killing wildlife, explained Paul Schmidt, assistant director at the Migratory Bird Program for the U.S. Fish and Wildlife Service.

While it’s against federal law to kill or harm any endangered, threatened or migratory bird species, the agency has not prosecuted any wind farm owner.

Instead, the service is working with the wind industry, scientists and conservationists to establish guidelines for how wind companies should place and operate a wind farm, Schmidt said.

A draft of those guidelines was released for comment this month.

Once the guidelines are adopted, the Fish and Wildlife Service will have a basis to decide which companies to investigate, Schmidt said.

“It’s just like you’re driving down the highway and the speed limit is 55,” he said. “You can go 60, probably 62, but at some point you are going to get caught.”

Schmidt said companies that volunteer information will avoid the scrutiny given those that do not.

Pattern and Iberdrola have regular communication with the service. But the reports they send are marked “privileged and confidential,” so they can’t be shared.

When Pattern gave its reports to the San Antonio Express-News, it called them public but then requested it preapprove anyone who saw them and that they not be posted online.

“Clearly we have a problem with transparency with the wind and wildlife issues, and I think we have a ways to go,” said Edward Arnett, director of programs at Bat Conservation International, whom Pattern approved to review its studies.

With wind farms across the country reluctant to share data openly, the understanding of the cumulative effect on wildlife and the best way to minimize it are stunted, Arnett said. This is especially true of bats.

At 150 feet long, the wind turbine blades move between 100 and 180 mph at their tip. The pressure change on the trailing edge is enough to cause internal hemorrhaging in bats, according to Bat Conservation International.

Before the Kenedy wind turbines went in, Arnett had expected low bat mortality, as there were no known concentrations of bats in the area. Since so little is known about bat movements, he is not surprised the numbers turned out to be higher.

Before wind turbines were built, little was known about bat movements.

It isn’t possible to know what is and isn’t working, he said.

“Until we have the information published in a credible fashion that is publicly shared and published in journals, it is going to be unknown,” he said.
