Wind energy keeps growing in popularity as a renewable energy source. But for a group of people in the Bureau County town of Ohio,Ill., it’s growing into a major problem.

“It sounds like an airport at my house and I live in the country,” Al Harris, an Ohio resident for eight years, said.

“You can’t go outside and enjoy the peace and quiet,” Deb Anderson, a 16-year resident of Ohio, said.

The Big Sky wind farm in Ohio began operating in September. The spinning turbines have meant great things for the environment, but hardships for its residents.

“There are three issues: one is television reception, one is shadow flicker, and the other one is noise,” Anderson said.

Their TV’s are sometimes unusable. The spinning turbine blades block the air waves from getting to their antennas causing a loss of signal.

The giant arms of the turbines cast spinning shadows over their homes and through their windows all day long.

And the noise is 10 to 20 decibels over the maximum allowed amount.

“We got no TV to speak of and the noise. It’s just not right. You can’t come into somebody’s area and do that and not do something about it to fix it. [The wind farm operators are] not seeming to do anything,” Harris said

The farm is operated by Edison Mission Energy. In a statement, the company said problems are not uncommon and they are working to fix any issues. But so far, the residents say the problems still persist.

“All we’re asking for is just to fix it and we’re not getting much response,” Harris said.

On Monday night, Harris, Anderson and more of their neighbors will attend a meeting with the Bureau County Board of Appeals with the goal to limit future wind farms.

“We don’t want anymore permits given out because they have to fix the issues they have now,” Harris said.

“I hope that the Board of Appeals will deny the conditional use permits that are being asked to be renewed,” Anderson said. “I would hope they would deny that, take the time to study all the issues that have come forward, and let’s get this problem resolved.”

The meeting with the Board of Appeals will take place at 7 o’clock Monday evening at the Bureau County Courthouse in Princeton, Ill.

CUSTOMER GROUPS OPPOSE INCREASE

Clogged transmission lines will prevent green power generated by Wisconsin Power & Light Co.’s new Minnesota wind farm from reaching Wisconsin, so the Madison utility’s ratepayers shouldn’t have to pay higher prices linked to the nearly $500 million project.

That’s the argument presented to state energy regulators Monday by two customer groups that want to block a price increase from taking effect for WP&L customers on Jan. 1.

The customer groups say the Madison utility failed to disclose information about potential transmission problems that could prevent the Bent Tree Wind Farm project from generating as much power as the utility envisioned.

“Ratepayers should pay for only the goods they get, not the sales pitch they were given,” the Wisconsin Industrial Energy Group (WIEG) and Citizens’ Utility Board (CUB) said in a filing with the PSC on Monday.

But Wisconsin Power & Light said it has been transparent in providing information to regulators about the project and the status of securing enhanced transmission capacity to move the power from the wind farm in southern Minnesota to Wisconsin.

“CUB and WIEG’s allegations are unfounded and unsupported,” the utility said.

The utility said it expects transmission constraints to be resolved within a few years that would enable the project’s full output, 200 megawatts, to be able to flow onto the power grid.

At issue is WP&L’s proposal to raise rates by $18.9 million, or 1.9%, in January. The protests about the Bent Tree wind farm were raised by the same groups that filed suit last year seeking to overturn the state’s approval for the project.

A Dane County Circuit Court judge ruled last week that the Public Service Commission didn’t need to use a more exhaustive review process for Bent Tree. The wind farm is under construction, with turbines now being delivered to the site and erected, said utility spokesman Steve Schultz. The project is expected to open in phases beginning in November, with the entire project slated to be done by March, he added.

WIND TURBINES IN THE NEWS:

WIND TURBINE NOISE, AN INDEPENDENT ASSESSMENT

SOURCE Herald Gazette, knox.villagesoup.com

By Stephen Ambrose and Robert Rand,

Stephen Ambrose and Robert Rand are members of the Institute of Noise Control Engineering. In 2009, they became concerned about the negative comments from residents living near wind turbine sites and, the apparent lack of regulatory action to address the potential for adverse health impacts from wind turbine generator noise in Mars Hill. They launched their own evaluation, and came to the following conclusions in a series of guest columns.

Wind turbines larger than one megawatt of rated power have become an unexpected surprise for many nearby residents by being much louder than expected.

The sounds produced by blades, gearing, and generator are significantly louder and more noticeable as wind turbine size increases. Long blades create a distinctive aerodynamic sound as air shears off the trailing edge and tip.

The sound character varies from a “whoosh” at low wind speeds to “a jet plane that never lands” at moderate and higher wind speeds. Blade-induced air vortices spinning off the tip may produce an audible “thump” as each blade sweeps past the mast.

Thumping can become more pronounced at distance, described as “sneakers in a dryer,” when sounds from multiple turbines arrive at a listener’s position simultaneously.

Wind turbines are not synchronized and so thumps may arrive together or separately, creating an unpredictable or chaotic acoustic pattern.

The sounds of large industrial wind turbines have been documented as clearly audible for miles. They are intrusive sounds that are uncharacteristic of a natural soundscape.

Studies have shown that people respond to changes in sound level and sound character in a predictable manner. A noticeable change in sound level of 5 decibels (dB) may result in “no response” to “sporadic complaints.” An increase of 10 dB may yield “widespread complaints,”; a 15 dB increase “threats of legal action.”

The strongest negative community response occurs with an increase of 20 dB or more, resulting in “vigorous objections.”

Audible tones, variability in sound level, and an unnatural sound character can amplify the public response. For a distinctive or unpleasant sound, a small change in sound level, or the sound simply being audible, may provoke a strong community response.

Community response can intensify further if sleep is disturbed and quality of life or property is degraded.

Weather conditions influence the sound level generated and how it travels to nearby homes. Sound waves expand outward from the wind turbine with the higher frequencies attenuating at a faster rate than low frequencies.

Locations beyond a few thousand feet may be dominated by low frequency sounds generated by the wind turbines.

Wind turbulence and icing, both common in New England due to topography and latitude, increase aerodynamic noise from intensified or chaotic dynamic stall conditions along the blade surfaces.

Atmospheric conditions at night and downwind enhance sound propagation toward the ground by increasing levels over longer distances.

Wind turbines are elevated hundreds of feet to receive stronger winds yet winds down on the ground or in nearby valleys may be non-existent with correspondingly low background sound levels, accentuating the impact of the intrusive sounds.

Other professionals have developed thresholds, or criteria, for sound level to protect public health that may be applied to planning for wind turbine permitting.

Recommendations from Hayes McKenzie Partnership in 2006 limited maximum wind turbine sound levels at residences to 38 dBA and no more than 33 dBA when “beating noises” are audible when the turbines spin.

Dan Driscoll presented his analysis in 2009 (Environmental Stakeholder Roundtable on Wind Power, June 16, 2009) with a Composite Noise Rating analysis of 33 dBA to reduce rural community response to the level of “sporadic complaints.”

Michael Nissenbaum issued his findings in 2010 from his medical study at Mars Hill, recommending a 7000-foot setback for public health.

The World Health Organization published sound level thresholds of sleep disturbance and adverse health effects from peer-reviewed medical studies (Night Noise Guidelines for Europe, October 2009).

Our next column will compare our sound level versus distance data with these medical, health, and community response criteria and show what distances are necessary to protect public health.

Currently there is no effective, reliable noise mitigation for wind turbines of this size other than shutdown.

Therefore, at this time it appears appropriate that proposed wind turbine sites should position wind turbines at least one mile away from residential properties and further for sites with more than one wind turbine. Smaller wind turbines (under one megawatt power rating) produce less noise than those currently being marketed and installed for grid power in Maine; these may be an option when distance is an issue.

State of Maine finds Fox Island Wind Turbines in violation of noise standard

Click on the image below to watch Wisconsin wind siting council members discuss the the relative necessity of a safety setback from large wind turbines. Two council members representing groups that lobby on behalf of wind development believe in this case, safety is a relative term. Because they do not believe safety is an issue when it comes to siting turbines, they suggest the term "courtesy setback" instead of "safety setback"

Click on the image below to watch part of a Wisconsin Wind Siting Council Meeting where Council member and wind lobbyist Michael Vickerman claims that community acceptance of wind projects is higher when there are fewer turbines. Council member and UW Professor Emeritus, Dr. Doug Zweizig asks Vickerman for support for his claims and and in the discussion it is revealed that the turbines in the projects cited by Vickerman are much smaller than the 400 to 500 foot turbines now being proposed. Vickerman then claims the size of the turbines doesn't matter.

Where does the wind developers preference for a noise limit of 50dbA come from? A wind lobbyist explains why the type of wind developers interests he represents want the turbine noise limit to be as high as 50daA and what it's based on. The World Health Organization says for restful sleep, 35dbA is the limit for nighttime noise.

Columbia County Gives Wind Energy a Nod

SOURCE Capital Newspapers, www.wiscnews.com

May 21 2010

By LYN JERDE,

PORTAGE – The Columbia County Board of Supervisors offered tepid approval Wednesday to a resolution declaring electricity-generating wind turbines on five parcels of farmland are in keeping with the landowners’ farmland preservation agreements with the state.

But the non-unanimous voice vote assent didn’t come without questions about the effects of the turbines on farming, and about how the county’s approval or disapproval of the resolution might affect the future of what could soon be the state’s largest wind energy farm.

We Energies plans to build Glacier Hills Energy Park, beginning this spring, on leased farmland in the towns of Randolph and Scott. Plans call for up to 90 wind turbines, capable of generating up to 207 megawatts of electricity.

Five of the parcels leased for turbine locations – four in the town of Randolph, one in the town of Scott – are subject to farmland preservation agreements with the state.

The intent of the resolution was to declare the county’s conclusion that locating a turbine on the land is not inconsistent with the agreement that the land must continue to be used for agricultural purposes.

But why, asked Supervisor Debra Wopat of Rio, is Columbia County even addressing this issue?

The towns of Randolph and Scott are not covered under the county’s zoning ordinances. And the farmland preservation agreements, she said, are between the landowners and the state’s Department of Agriculture Trade and Consumer Protection.

Kurt Calkins, director of Columbia County’s land and water conservation department, said it was the county board that originally approved forwarding the farmland preservation agreements to the state – so the County Board has to authorize a change in the agreement to reflect the presence of the windmills. The DATCP will agree that the windmills do not impede agricultural use of the land if the county also agrees to that, he said.

“The real question is, do you deem them consistent with agricultural use? That’s the question the state has asked us to answer,” Calkins said.

Supervisor Fred Teitgen of rural Poynette questioned whether the turbines are good for rural areas.

“There are problems with large wind turbine systems, especially with noise and shadow flicker,” he said.

That was why Teitgen proposed amending the resolution to say, “Columbia County believes [that] a wind turbine structure may not (instead of will not) conflict with continued agricultural use in the area,”

He also proposed adding to the resolution a condition that the turbines should be sited properly in accordance with Wisconsin Public Service Commission standards and local requirements.

This amendment failed on a voice vote.

Supervisor Brian Landers of Wisconsin Dells said he was concerned that the revision might imply that the county can or should provide oversight for the construction of the We Energies turbines. If that’s the case, Landers asked, then which department would be responsible for the oversight, and at what cost to the county?

“I would be hesitant to add language that we somehow have a governance of this if we don’t have the legal authority to do so,” Landers said.

When Supervisor John Tramburg of Fall River asked how much farmland would be consumed by the turbines and related structures such as roads, Walter “Doc” Musekamp of We Energies said that, among the five land tracts in question, a total of 3.4 acres would be taken out of production for roads and foundations.

Construction of the roads and other ancillary structures is expected to start this spring.

Wind Farms vs. Doppler Radar

SOURCE: WMBD/WYZZ Chief Meteorologist Marcus Bailey

Lincoln -  Last year a weak tornado touch-downed near Holder in eastern McLean county. That's near the Twin Groves wind farm, one of the largest in the state.

Chris Miller, Warning Coordinating Meteorologist for the National Weather Service in Lincoln explains what happened next.    

"When that storm enter the wind farm area, because the rotation was weak we lost that signature as it went through the wind farm."  Says Miller.  "We had to rely strictly on storm spotter reports in the area."

Here's the concern:  The Doppler Radar beam hits the blades on a wind farm tower, causing interference.  That interference looks similar to a thunderstorm.  Current Doppler Radar uses software to filter out objects that are stationary, but rotating wind tower blades are an issue.

"We don't want to eliminate actual moving storms, but somehow the Radar would need to decide in what area the wind turbines are located and how fast they're moving and then try to remove some of that."  Says Miller.  "That's a very difficult problem to try to do software related."

This isn't an issue when the weather is fair; but when severe weather approaches or moves over a wind farm, meteorologists may not be able to pick out certain features; most specifically tornadoes.  

There are two wind farms that impact the Doppler Radar in Lincoln.  Railsplitter in southern Tazewell and northern Logan counties is the closest and most commonly seen on Radar.  A proposed wind farm may be built in western Logan county, which could also affect Radar images once completed.

So what's next?  National Weather Service officials are educating wind farm developers on their potential impact on Doppler Radar. 

"There is open dialog for the wind farm developers, but if anything we just want to educate them on what some of the concerns are."  Says Miller.  "Hopefully we have future discussions about what can be done to help mitigate the problem."


Tom Vinson, Director of Federal Regulatory Affairs with the American Wind Energy Association says wind developers are in discussions with the National Weather Service on this matter.    The Association hope that the Weather Service can develop software to take care of the problem.

"The preference on the industry side would be for a technical solution that would resolve the problem without having to necessarily give up energy production at certain times."  Says Vinson.   "It's certainly something that should be discussed but it's not something that we have definite agreement on today."  

We contacted Horizon Wind Energy, the owner of the Railsplitter wind farm.  They had no comment on our story.  Oklahoma University scientists are conducting studies on the issue.
