4/16/11 What's happening with Wisconsin's wind rules? Recommended Reading: Rep. Frank Lasee's proposal

PROPOSED WIND FARM REGULATIONS
SOURCE: WFRV GREEN BAY
BROWN COUNTY, Wis. (WFRV) -- A proposal from an area lawmaker will make it even harder for wind farmer developers to build in the state. This after two developers recently pulled the plug on projects in Northeast Wisconsin.

David Enz built his home for his family back in 1978. But last month he and his wife decided they could no longer stay.

"Started feeling pressure in my ears, feeling pressurized, started feeling unstable," Enz said.

Enz attributes the symptoms to the eight wind turbines that were built last fall about a half mile from his house.

"It gets to the point where your body just does not want to be here, it just can't be here," said Enz.

Today, State Senator Frank Lasee introduced legislation that would require developers to keep turbines at least 2,250 feet from a person's property unless there's permission to build closer.

Right now, they need to be at least 1,250 feet from homes. Earlier this year, Governor Scott Walker said he wanted to change the law to 1,800 feet.

Senator Lasee says that's not enough.

"Two thousand fifty feet is a reasonable distance that will help preserve their health and safety because of shadow, flicker, noise and I believe there is either magnetic or electric noise that causes health problems for people," Lasee said.

Last month, two wind farm developers pulled out of projects in both Brown and Calumet Counties, saying the current regulations already go too far.

According to Senator Lasee, the strict regulations aren't what's driving companies away from projects here in Wisconsin. He says it all comes down to money.

"Many utilities are no longer paying premiums which drive up our electric costs for wind energy so they're having trouble getting a contract that would pay," Lasee said. "I think they're using this as an excuse."

Enz hopes the Senator's proposal can prevent other families from going through what he has.

"We have a house that we can't live in," he said.

Enz and his wife have been staying with their children for the last few weeks. Senator Lasee is circulating the bill in the senate and assembly.
LASEE BILL WOULD CHANGE RULES FOR WIND ENERGY SYSTEMS
Sen. Frank Lasee is circulating for co-sponsorship a proposal revising PSC authority over wind energy system siting. Basically, the bill requires owners of a large wind energy system to design and construct the system so a straight line distance from the vertical center line of any turbine in the system to the nearest point on the property line be at least one-half mile. The distance could be shorter if the system owner and property owners agree to a lesser distance. The bill also changes the distance from the vertical center of any turbine to the permanent foundation of any building.

4/6/11 What Would John Muir Say?

WIND FARM EFFICIENCY QUIRIED BY JOHN MUIR TRUST STUDY

 SOURCE: www.bbc.co.uk

April 6, 2011

Wind farms are much less efficient than claimed, producing below 10% of capacity for more than a third of the time, according to a new report.

The analysis also suggested output was low during the times of highest demand.

The report, supported by conservation charity the John Muir Trust, said assertions about the ability of wind farms must be challenged.

It concluded turbines “cannot be relied upon” to produce significant levels of power generation.

The research, carried out by Stuart Young Consulting, analysed electricity generated from UK wind farms between November 2008 to December 2010

Statements made by the wind industry and government agencies commonly assert that wind turbines will generate on average 30% of their rated capacity over a year, it said.

But the research found wind generation was below 20% of capacity more than half the time and below 10% of capacity over one third of the time.

‘Different manner’

It also challenged industry claims that periods of widespread low wind were “infrequent”.

The average frequency and duration of a “low wind event” was once every 6.38 days for 4.93 hours, it suggested.

The report noted: “Very low wind events are not confined to periods of high pressure in winter.

“They can occur at any time of the year.”

During each of the four highest peak demands of 2010, wind output reached just 4.72%, 5.51%, 2.59% and 2.51% of capacity, according to the analysis.

It concluded wind behaves in a “quite different manner” from that suggested by average output figures or wind speed records.

The report said: “It is clear from this analysis that wind cannot be relied upon to provide any significant level of generation at any defined time in the future.

“There is an urgent need to re-evaluate the implications of reliance on wind for any significant proportion of our energy requirement.”

According to figures from industry body Scottish Renewables, which has yet to comment on the report, electricity generated from renewable sources in the UK grew from 5.6% of total UK electricity generation in 2008 to 6.7% in 2009.

WIND FARMS REMAIN AN ISSUE IN GLENMORE, MORRISON

Source: Green Bay Press Gazette

March 31, 2011

By Doug Schneider

Wind farms remain a campaign issue in two southern Brown County towns, despite a company's recent decision to cancel plans for 100 wind turbines in Morrison, Glenmore and other nearby communities.

Invenergy LLC said it would not pursue permits for a wind farm in the area, but campaign signs related to wind energy continue to dot the landscape, and candidates say they still need to be prepared with future proposals that could affect residents' quality of life.

"We have to keep in mind that there are other projects like this out there, smaller developments," said Todd Christensen, who is seeking re-election as Morrison town board chairman, "and there could be more in the future."

Invenergy would have put 54 turbines in Morrison, four in Glenmore, and others in Wrightstown and Holland. Because some town officials expect there will be other developments proposed, towns are banding together to push for consistent regulations on issues related to windmills, and are asking state officials to consider their concerns. A handful of wind turbines were built as part of another project off Wisconsin 96 near the hamlet of Shirley.

But candidates also say there are issues beyond wind-energy regulation.

Cliff Hammond, who is challenging Christensen, said the next town board also will need to work to maintain a balanced budget as financial support from the state and county decline.

Kriss Schmidt, who is running for board chairperson in Glenmore, said board members will have to make sure basic services like snowplowing and road-patching are maintained.

Pat Kolarik, who also is running for Glenmore board chair, said the key for elected officials will be to focus on maintaining residents' quality of life whether the issue is wind energy or something else.

"There are going to be a number of challenges we have to address — budget, services, appropriate setbacks for any structure," she said. "The goal for me would be to work with residents on appropriate solutions."

ENERGY SOLUTION OR LEGAL TROUBLE?

SOURCE: Hudson Star Observer

March 31 2011

"The controversial energy project in Forest has come under fire and may be stopped by a federal lawsuit which was filed by a citizens’ group in February."

A legal battle in northeastern St. Croix County highlights the difficult issues of wind-generated power. Talk to anyone and they will, in general terms, talk about wind power as a good, efficient and cheap energy source for the times — be it today or tomorrow.

Try finding a location to construct wind generators and suddenly you’ve got yourself a first-class controversy, complete with arguments among neighbors, recalls and lawsuits.

Such is the case in St. Croix County in the town of Forest.

The controversial energy project in Forest has come under fire and may be stopped by a federal lawsuit which was filed by a citizens’ group in February. That suit was also supported by action of a new town board that was elected through a successful recall election. The former board had approved the proposed wind energy project last summer.

A citizens’ lawsuit was filed in February. In March, the new town of Forest board voted to rescind a wind energy development agreement and other approvals that had been granted to a wind developer. The project, being proposed by a private developer named Emerging Energies, is in jeopardy.

The project in Forest called for 39 wind towers. Each tower stands about 500 feet tall.

Many landowners in the town had signed leases with the wind firm, but were prohibited from discussing the project. When the rest of the town’s residents got “wind” of the deals, the uprising began.

Now there are battles over setbacks, noise, quality of life, health, property value, safety and more. Emerging Energies, LLC, has also threat-ened the new town board with legal action.

A similar scenario developed in the eastern part of the state when a Chicago wind energy developer, Invenergy LLC, dropped its plan to build a large wind farm near Green Bay.

Opponents in the Green Bay area are expressing the same concerns and claim they will continue to work to prevent the “irresponsible development of industrial wind projects.”

State energy regulators are now trying to come up with a plan to help support wind projects. Regulators may be asked to go back to the drawing board to develop statewide rules governing wind power projects, under a bill to be considered this week.

The Legislature’s joint committee for review of administrative rules voted earlier this month to temporarily block a wind farm site rule developed by the state Public Service Commission.

Supporters of wind energy development say legal problems will stall development, leading to a loss of jobs tied to wind turbine construction as well as revenue for host property owners and local governments. There seems to be plenty of controversy over, among other things, setbacks for wind towers.

A property rights bill introduced by Gov. Scott Walker in January would restrict wind towers from being placed less than 1,800 feet from a property line. That bill had the apparent support of wind farm opponents and the Wisconsin Realtors Association.

In its most recent wind farm decision, the PSC ruled that 1,250-foot setbacks be required for We Energies’ Glacier Hills Wind Park, now under construction in Columbia County.

The bottom line is, when wind towers begin popping up in either populated areas, or rural countryside, there is likely to be plenty of opposition. A group of wind towers doesn’t do much for the scenic value of any topography.

Despite all the virtues of wind power, developing a power source to a degree where it would have a significant impact could be difficult when facing “not in my backyard” neighborhoods.

MIDWEST WIND SUSPENDS DEVELOPMENT WORK IN STATE

"Wind industry representatives said the PSC rule was restrictive because it set specific decibel limits for turbine noise and shadow flicker restrictions as well as setbacks."

Midwest Wind Energy is suspending development of two wind farms in Wisconsin, the Illinois company said Wednesday.

The company developed the Butler Ridge wind farm in Dodge County and the Cedar Ridge project in Fond du Lac County, projects now owned and operated by other companies.

Midwest Wind said it was actively working on a 98-megawatt wind farm in Calumet County and another project for which a location had not yet been announced.

Midwest Wind cited development opportunities in other states at a time when Wisconsin policymakers are moving to restrict wind farm development.

"Most states are clearly open for renewable energy development and the economic development dollars and jobs that come with it,” said Stefan Noe, company president. “So long as there are states rolling out the welcome mat it doesn't make sense to devote significant dollars to a state that is creating unreasonable roadblocks for wind development."

The action came one week after Invenergy of Chicago canceled plans to develop a large wind farm near Green Bay, and one day after a legislative committee voted to introduce a bill sending wind siting rules back to the state Public Service Commission for more work.

Republican lawmakers and Gov. Scott Walker have said the PSC rule allowed turbines to be built too close to nearby homes. Wind industry representatives said the PSC rule was restrictive because it set specific decibel limits for turbine noise and shadow flicker restrictions as well as setbacks.

A bill that passed in the Legislature two years ago called on the PSC to set up a uniform standard for wind projects across the state, to replace a patchwork of local rules and moratoriums that were in place with regard to wind projects.

Keith Reopelle, senior policy director at the environmental group Clean Wisconsin, said the new chair of the PSC, Phil Montgomery, was a co-sponsor and supporter of the bill that called on the PSC to set statewide standards. He said he hoped the agency would move quickly to develop a workable set of rules.

When the bill was introduced in 2009, Montgomery – then a state lawmaker from Brown County and ranking Republican on the Assembly energy and utilities committee - released a statement in support of a uniform state standard.

“Wind power is job-creating power,” Montgomery said in April 2009. “A fair and uniform state standard for siting wind developments will create an environment of investment in our state while moving us closer to our green energy goals.”

WIND TURBINE PLANT ON HOLD

"I think we had to give them every opportunity to succeed," council member Lee Albrecht said. "You have this carrot dangling out there that there are 600 jobs on the horizon; I think you have to do whatever you can to have that carrot come to you."

Wisconsin Rapids is ready to buy back land it sold to a local company that two years ago announced plans to build a wind-turbine blade manufacturing plant on the property.

Energy Composites Corp. faces a Friday deadline to either reach an agreement with Wisconsin Rapids or sell the nearly 94 acres of land back to the city at the original purchasing price, Mayor Mary Jo Carson said.

Carson said the sale doesn't necessarily mean the project is dead, but it won't happen right now.

"Obviously, ECC doesn't want to hold us up in reference to that land, which we thank them for," she said. "We appreciate their interest in their hometown."

Carson said City Attorney Sue Schill has been working with the company's attorney to reach a buy-back agreement.

On March 31, 2009, the company announced plans to build a 350,000-square-foot plant in the Rapids East Commerce Center that would create at least 400 local jobs. Since then, those plans expanded to 535,000 square feet and more than 600 positions.

To facilitate the project, the city later sold the Wisconsin Rapids-based company 93.7 acres of land in the Rapids East Commerce Center for $500 an acre -- a 90 percent discount from the typical asking price -- plus a $1,000 option fee, for a total price of $47,850.

Under the pending agreement, the city would buy back the land at the same price for which it sold it, Carson said.

"I'm glad to see it being sold back to the city at the original price," City Council member Marion Hokamp said. "The sooner they do it, the better it's going to be. Maybe we're going to get somebody else interested (in the property)."

As part of the original development agreement, the city would have paid $1.5 million for infrastructure costs, including extending city streets and expanding railroad access to the property, and $6,000 for each full-time job the company created on or before Dec. 31, 2012, up to $3.8 million.

At this point, Wisconsin Rapids has not invested any money in the project, city Finance Director Tim Desorcy said.

A decline in bond market conditions led company officials to put the project on hold while they searched for investors. Those efforts have been unsuccessful.

Hokamp, who has publicly criticized Energy Composites for a lack of action, said the city should have bought the property back sooner. She remained skeptical of the project throughout the process.

"Way back when they started, I never thought it was going to be done," she said. "They knew they weren't going to have anything out there a long time ago."

Other council members do not regret giving the company so long to bring the plan to fruition.

"I think we had to give them every opportunity to succeed," council member Lee Albrecht said. "You have this carrot dangling out there that there are 600 jobs on the horizon; I think you have to do whatever you can to have that carrot come to you."

COMMITTEE VOTES TO SUSPEND WIND-SITING RULES

March 1, 2011

By Andy Szal

The Joint Committee for Review of Administrative Rules this morning voted to suspend wind turbine siting regs that were set to take effect today.


The committee voted 5-2 along party lines to suspend PSC rule 128 and now has 30 days to submit a bill repealing the measure to the full Legislature.


Rep. Gary Hebl, D-Sun Prairie, accused the majority of going around the normal legislative process and flip-flopping, since a number of Republicans supported the wind siting bill last session.


"This wasn't a flash in the pan, fly by night rule," Hebl said.


Sen. Leah Vukmir, R-Wauwatosa and the committee co-chair, said the committee had a duty to reconsider the PSC rule after lawmakers voiced concerns about the issue early in the new session. Rep. Dan LeMahieu, R-Cascade, added, "We didn't vote for the rule. We voted to give them the authority to promulgate a rule."


Rep. Fred Kessler, D-Milwaukee, said the bill would have a particularly detrimental effect on the wind turbine industry in Manitowoc.


"These jobs probably will go to other states," Kessler said.

WIND FARM COMPLAINTS

"As the sun comes across the sky, it hits the turbine blades and causes this flicker," she said.

Nearby homeowners say it can go on for hours. "When it first happened, we felt there was something wrong with the electricity because it felt like every light was blinking,"said Barb Draper.

People crowded a meeting in Princeton, Illinois Monday night to express their concerns about wind farms. Residents packed into a meeting with the Bureau County Board of Appeals. Some want to put a stop to the proposed Walnut Ridge wind project. It would build 150 turbines over more than 15,000 acres and affect more than 75 landowners.

Others at the meeting are already surrounded by wind turbines from the Big Sky wind farm. They want the county and the companies to focus on issues caused by the current turbines. They complain that the turbines are noisy, cast flickering shadows that can cause seizures and even block television reception.

The Anderson family in rural Ohio, Illinois says it has turned their quality of life and turned it into living in an industrial park. THe nearest wind turbine is 1,750 feet from their home. Deb Anderson says ever since the turbines started running, their life hasn't been the same.

"As the sun comes across the sky, it hits the turbine blades and causes this flicker," she said.

Nearby homeowners say it can go on for hours. "When it first happened, we felt there was something wrong with the electricity because it felt like every light was blinking,"said Barb Draper.

"On, off, on, off as the blade caught the sun it made a very disturbing motion. It almost made you sick to your stomach." added Bob Draper.

Another problem that came up after the turbines were turned on is with their TV reception. The family says it varies, depending on the direction of the blades. Some days, the family gets 15-20 channels. During our visit, they could only get in two.

On top of that there's the noise that won't go away. These property owners say they understand the benefits of the wind farms. But they'd like the problems fixed before more wind turbines come into the area.

The wind power company has put up two antennas on their house, but the family says they didn't help. They company also offered them money to buy a better delivery system, like satellite TV.

Ryan Light in the Director of Renewable Energy for the Eastern Iowa Community College District. He says those are some of the drawbacks for people living near large wind farms.

"One effect we need to look at a little harder into is the flicker effect, which is the spinning of blades and shadow cast. For people with certain medical concerns it can cause seizures," Light said.

He says there are companies working to alleviate the radio interference with a new kind of blade and there is more research being conducted on noise reduction systems.

SPLIT DECISION FINDS WE ENERGIES DIDN'T EARN TOO MUCH

SOURCE: Milwaukee Journal Sentinel

March 1, 2011

By Thomas Content

In a 2-to-1 vote, state regulators ruled Thursday that We Energies won’t have to issue credits to its 1.1 million electricity customers for profit it earned in 2008 and 2009.

Commissioner Lauren Azar sided with customer groups that had called for the commission to vote to return money to customers, saying the commission should decided that the utility earned more than its maximum profit allowed the regulated utility – 10.75% in 2008 and 2009.

But commissioners Eric Callisto and Mark Meyer voted not to require any profits to be returned to customers. Meyer said it was inconsistent for the commission to be seeking to return profits to customers when a utility earns above its maximum profit level since the commission does not allow utilities to raise rates when utilities fail to earn as much in a given year as the profit level, or return on equity, set by the commission.

Over the past 10 years, utilities have more often earned less than their return on equity, Meyer said.

The debate at Thursday's meeting ended up boiling down to how Callisto and Azar interpreted whether management bonuses paid to utility executives should be included in the calculation of a utility’s profit.

Callisto said the commission specifically excludes management bonuses and incentive pay from being collected in utility rates and that the commission staff will be conducting an investigation of utility bonuses in upcoming rate cases.

He said his position in this case was consistent with how the commission interpreted the issue in setting new rules for how utilities can raise rates when fuel prices climb.

Azar, who wanted the issue of bonuses addressed in the new fuel rules last year, said she has not changed her view. She said she considered utility bonuses too high for a regulated utility, given the state of the economy, high poverty rates in the We Energies service territory. The utility's "shareholders are doing quite well," she said.

In filings with the commission, We Energies had argued that the commission was shifting from utility regulator to utility micro-manager if it adopted the proposal of Azar and customer groups. The utility also argued that the commission has not had a consistent definition for utilities to determine what would and would not be included in a PSC calculation of whether a utility earned too much profit.

Callisto agreed. The issue came up in one prior case – in which the commission also ruled in We Energies’ favor – but the commission’s guidance to utilities on this issue has been “ephemeral.”

An analysis by We Energies prepared last week indicated that the utility could have been required to return $53 million to customers. Based on the majority decision Thursday, the commission determined that the utility earned profit of 10.36% in 2008 and 10.52% in 2009, below the 10.75% profit allowed by the PSC.

That means the utility $25.7 million less than the maximum, according to the filing.

FALMOUTH OFFERS PARTIAL TURBINE SHUTDOWN

SOURCE: Cape Cod Times, www.capecodonline.com

March 1, 2011

By Aaron Gouveia,

FALMOUTH — Falmouth officials have offered to turn off the town’s wind turbine for three hours a day, following noise complaints from neighbors.

Acting Town Manager Heather Harper proposed the partial overnight shutdown, calling the offer a “good faith effort toward a mutual resolution of the matter.”

After tracking complaints regarding the 1.65-megawatt turbine off Blacksmith Shop Road, known as Wind I, town officials found residents are most affected during periods of high winds in the late evening and early morning hours, Harper wrote in a Feb. 23 letter.

“We intend to modify the operation of the machine between the hours of midnight and 3 a.m., the times at which the background noise may be lower than the sound emanating from our wind energy equipment,” Harper wrote.

Details of the town’s offer are still unclear, however. Harper’s letter did not specify whether the turbine would be turned off for three hours every night or only during periods of high winds.

When approached by a Times reporter prior to Monday’s selectmen’s meeting, Harper said she did not know the answer and was unable to provide one before the start of the meeting. The meeting was still in progress as of the Times’ deadline.

But Gerald Potamis, the town’s wastewater superintendent who oversees operation of Wind I, said the change will go into effect as soon as the turbine manufacturer, Vestas, sends a technician to reprogram the turbine.

The shutdown is an “interim solution” until town officials and neighbors can work out a permanent solution, Potamis said.

But Christopher Senie, an attorney representing 18 residents who claim they are adversely affected by turbine noise, vibrations and shadow flicker, has said the town’s offer is not good enough.

Senie, who was not available for comment Monday, penned a Feb. 25 letter that stated this is the second time in four months Harper has made the offer to his clients.

Senie called the three-hour reprieve “wholly inadequate” in his letter, and wrote the suffering of neighbors “will not be lessened in any meaningful way.”

The only acceptable interim solution, he wrote, is to shut off Wind I whenever wind speeds reach 23 mph. It is a proposal Harper has repeatedly rejected, according to Senie’s letter.

“This is the only meaningful way to provide my clients some relief while the ultimate solution is developed and implemented,” Senie wrote.

Todd Drummey, who lives approximately 3,000 feet from Wind I, said the town’s offer “completely misses the point” because it assumes residents will be satisfied with three hours of sleep every night.

“It’s the same offer from back in October,” Drummey said. “It was ridiculous then and it’s ridiculous now.”

The ultimate goal, according to Senie and his clients, is to convince the town it was wrong not to require a special permit before the turbine became operational.

Building Commissioner Eladio Gore deemed the turbine a municipal use, and cited zoning bylaws that exempt “all municipal uses” from the special permit process. Senie, on the other hand, cited another local bylaw specifically pertaining to windmills, that requires a special permit in all instances.

Last month, three members of the zoning board of appeals said Gore made a mistake in interpreting the bylaws. But the appeal failed because two ZBA members recused themselves, meaning a 4-0 vote was necessary to uphold the appeal.

But the neighbors are still hopeful because selectmen — acting as the owners of the turbine — can request a special permit at any time.

To that end, several neighbors showed up at Monday’s meeting hoping to persuade selectmen to start the special permit process, which will give neighbors a chance to negotiate some potential compromises. But they were not on the agenda, and as of 9:30 p.m. it was unclear whether they would be allowed to speak.

WOLFE ISLAND WIND PLANT STILL HARMING BIRDS IN IMPORTANT BIRD AREA

SOURCE: Nature Canada, www.naturecanada.ca

Last May, Nature Canada’s Ted Cheskey blogged about a report that described how birds and bats have been affected by the TransAlta wind plant on Wolfe Island, a globally significant Important Bird Area in southern Ontario known for its waterfowl, raptors and swallows. He called the numbers of birds and bats being killed by TransAlta’s turbines “shockingly high,” indeed the highest recorded in Canada and one of the highest in North America.

However, since the report only studied a six month period, TransAlta’s spokespeople argued that it was premature to reach conclusions so soon, especially when comparing the Wolfe Island deaths to yearly casualty rates for other wind plants. Besides, TransAlta reasoned, the results appeared to be within the thresholds of acceptable limits set by provincial and federal government regulators.

Then last month, Stantec Consulting, the firm that produced the original report, released its report on the second half of the year: January 1, 2010 to July 1, 2010.

And the results for birds are troubling.

Wolfe Island: Most Deadly Wind Plant in Canada

Though casualty numbers for birds did not skyrocket in the second sixth month period, a time that included the spring migration, they still were high enough to make the Wolfe Island wind plant the most deadly for birds in Canada.

The 13.4 birds per turbine casualty rate is about 7 times the industry average in Canada according to Canadian Wind Energy Association (CANWEA) but below the so-called “adaptive management” threshold for TransAlta facility, as set by various government agencies. That level is 11.7 birds per MW which translates to 21 birds per turbine, which just happens to be the highest level ever recorded at any wind facility in North America (Buffalo Mountain, Tennessee). Using the highest level recorded as the threshold before which any mitigation is even considered seems a bit dubious to say the least.

Estimated and actual numbers of birds killed, proportioned by the species actually found, over the entire 12 month period, paints a disturbing picture:

  • Tree Swallow 218 (calculation based on 31 corpses)
  • Purple Martin 49 (calculation based on 7 corpses)
  • Bobolink 73 (calculation based on 9 corpses)
  • Wilson’s Snipe 50 (calculation based on 7 corpses)
  • Red-tailed Hawk 10 (actual count)

It is important to note that the calculated numbers are arrived at using Stantec’s formula to calculate total casualty rates. A sample of turbines are visited either weekly or twice a week and a search for bird corpses on the ground beneath the blades is conducted. As the method is not intended as a comprehensive search, determining the casualty rate requires taking in factors like the ability of the search team to find carcasses, the percentage of the area searched and the rate of predation between searches. The 31 Tree Swallow corpses, in other words, represent about 15% of the calculated number of tree swallows killed, based on Stantec’s calculations and field testing.

Birds Most Effected are Already in Serious Decline

While the report and the research behind it appear to be quite solid, the authors contend that the casualty rates are quite sustainable and will not have any effect on the species populations. They do this by contrasting the kill numbers from the turbines with the estimated Ontario population of the most affected species – Tree Swallow, numbering about 400,000 and Bobolink, about 800,000. (They do not do this for Red-tailed Hawk, which in fact may not meet their sustainability criteria). They also contrasted the numbers with estimates of birds killed by other human activities or artifices such as tall buildings, vehicles, cell towers, and pets.

While this argument has gained considerable traction among some in the wind industry and even the scientific community, it fails to consider that the turbines at Wolfe Island are killing different species than the tall buildings, cats and cars. Tree Swallow, Purple Martin, Red-tailed Hawk, Turkey Vulture and Bobolink rarely if ever show up on lists of casualties from tall buildings, and are unlikely victims of cats, with the possible exception of the Bobolink. And vehicle collisions, well – while this is a legitimate concern, Turkey Vultures have arguably had a net benefit from the carnage caused by vehicles.

But it is some of these very species – the ones most likely to be harmed by Wolfe Island’s turbines – that are already experiencing declines.

Take swallows, for example. Most species of swallow have declined significantly in Canada over the past 20 years. Adding additional threats to already stressed populations is not prudent. According to trend data on this species from Breeding Bird Survey routes in Ontario, the Tree Swallow has declined by about 6% annually over the past 20 years, a cumulative decline of almost 80%! In other words, the current estimated population of 400,000, was 2 million only 20 years ago. Bobolink, recently added to COSEWIC’s list of threatened species, declined 4.1% over the same period. We should not trivialize the impact of removing dozens, or hundreds of individuals from a population of species that are clearly in trouble.

In the meantime, good documentation of the impacts is essential. While TransAlta had to deliver these studies – they were a condition of the wind project’s approval – the company and Stantec should be recognized for doing good work. Once one takes the spin out of the document, the data and the methodologies are solid. The quality of the monitoring appears to be high, and some weaknesses, such as a potential bias to undercount the number of raptor fatalities, are recognized in the report.

With regard to birds of prey, even if they were not undercounted, the number of casualties is excessively high at .27 per turbine. This was the highest recorded rate for raptor kills outside of California. The victims included:

  • 10 Red-tailed Hawks,
  • 1 Northern Harrier,
  • 1 Osprey,
  • 2 American Kestrel,
  • 1 Merlin
  • 8 Turkey Vulture

This number crossed the “notification threshold” for the project, meaning that the CWS and MNR were notified about the high rates. The report states that TransAlta and MNR have initiated discussions regarding “adaptive management” in response to the raptor deaths. We look forward to hearing what the response might be.

Next Steps to Reduce Bird Deaths

With the plant already in operation, the only option now is to mitigate the risk to wildlife perhaps by slowing down the blades of the turbines at hazardous moments of the year, or turning them off. However, unless the numbers of casualties increase even further in the next two years, it is unclear how far the threshold must be exceeded and how often, before mitigation is implemented. It is reported in the document that four notifications were made by the company to the government for raptors alone, yet none appears to have led to mitigation.

Today, several wind farms are being proposed around the eastern end of Lake Ontario, the most worrying being Gilead’s Ostrander Point wind farm. Ostrander Point is an area that is arguably even more significant for birds than Wolfe Island, because of its specific geography. Ironically, the land on which the Gilead project is being proposed is owned by the Province of Ontario – a Crown forest block.

Opposition to turbines in agricultural areas appears to have persuaded government officials to meet their renewable energy agenda by prioritizing “crown lands” as locations for wind energy plants. While this might be appropriate and acceptable for some properties, when a wind plant is located in an area of great significance to wildlife, as is the case with Ostrander Point, so-called green energy ceases to be green at all. The Ontario government needs to think more carefully about where they allow wind turbines. It is not too late for the Province to design a policy that promotes green energy and also protects key biodiversity sites including Important Bird Areas.

Otherwise, as more of these facilities are built in bad places, wind energy will become a significant contributor to the declines of several species that are already in trouble, and the Green Energy Act will be recognized and remembered for all of the wrong reasons.

About Wolfe Island

Wolfe Island, located in the eastern end of Lake Ontario, a shore distance from Kingston, is about 32 kilometres long and about 11 wide in the widest area covering about 12,140 hectares.  The west end of the island is exposed to the westerly winds blowing across much of the length of Lake Ontario.   The island is a mixture of agricultural land under various regimes of management from annual crops to pasture, natural habitats from woodlands and patches of second-growth forest, to grasslands, wetlands and the residences and farms of the Wolfe Islanders.   TransAlta’s 86 turbines tower 80 metres above the farmland, pasture, and grasslands, and are constructed largely on the western side of the islands where the winds are probably the strongest.   The wind plant has a nameplate capacity of 198 Megawatts, but the average output in its first year of operation was only 48 Megawatts, a quarter of the capacity, due to the variability of winds.  This output number appears to be about average for Ontario’s wind industry. 

Wolfe Island is a Globally significant Important Bird Area, (IBA) recognized for its significance for waterfowl primarily, but also for its importance to raptors (birds of prey including hawks and owls) and Tree Swallows.  Being at the eastern end of Lake Ontario, the island’s habitats are also important stop-over destinations for migrating birds and bats.  Nature Canada believes that industrial wind plants should be excluded from IBAs, and other sites that are known to be highly significant for wildlife, particularly birds.   No wind plant, even the notorious Altamont plant in California, has ever, to our knowledge been decommissioned because of impacts on wildlife.   Once these things are built, then are not turned off until they stop working or break down.   For us at Nature Canada, this a strong incentive to encourage provincial policies to exclude wind plants from IBAs and important migratory corridors and fight the few existing proposals within IBAs.   However, the Wolfe Island plant is built and operating, so its impacts on birds and bats will be instructive for other projects being proposed or considered in areas that are significant for birds.

Journal, health agency wrong about turbines

Wisconsin State Journal, madison.com 21 August 2010

The State Journal’s editorial Wednesday, “Science says wind power safe,” provides false reassurance to its readers about the dangers of living in the vicinity of large wind turbines.

The “science” trumpeted in your editorial comes from an inadequate literature review conducted by under-qualified staff at the Wisconsin Division of Public Health — a staff that has not conducted a survey of the hundreds of people in Wisconsin now living in the vicinity of large wind turbines. They have not spent one overnight in a wind farm, the time when the most troublesome noise occurs.

Instead of caring for the difficulties of Wisconsin citizens and directly addressing the numerous complaints of sleeplessness and the ailments that result from disturbed sleep, the division has instead prepared a report from its undiscerning reading of the literature. It has told those suffering these effects that they have no complaint, and then the division has promoted this callous position to the press.

Wisconsin deserves better care from its Department of Health Services.
