Dropped Data Raises Concerns

February 26, 2015

Graph shows gaps in dataIberdrola missed a few deadlines on its way to meeting a self-imposed schedule to bring its turbines into line with the Mass. noise limits. As a result, the DEP issued a consent order with mandated deadlines, followed by a fine of $1000 per day if the violations continue. To comply with the order, Iberdrola must respond to complaints about noise. A recent complaint brought a less-than-stellar response, as indicated in the report.Stephen Ambrose letter to MADEP Analysis by acoustician Stephen Ambrose noted the data gaps, which he detailed in a subsequent letter to the Mass. DEP.

My professional opinion is that this wind-turbine compliance noise test is not credible and does not show that the turbines meet the Mass DEP noise limits.

Observers have noted that whenever sound monitoring is done at the Hoosac, significant data points are eliminated from the report findings.



Wind Turbine Noise–Complaints Easy to Understand

February 15, 2015

Wind turbine noise is different from other types of noise, as acoustician Stephen Ambrose explains through two charts. The first is from the study done in Sweden in 2004, when Eja Pedersen and Kerstin Waye illustrated their findings with the top graph below. In the second chart, Ambrose and Robert Rand developed a schematic to show the results of numerous studies which independently echo the lived experience of wind turbine neighbors. Too loud, which often means too close, is predictable from the volume of complaints.

Australian Research Yields Insights on Wind Turbine “Signature”

February 8, 2015

Acoustician Steven Cooper was commissioned by the Australian utility, Pacific Hydro, to investigate the complaints of families near the wind plant at Cape Bridgewater, Australia. The Cape Bridgewater Wind Farm Acoustic Study is a 235-page report, packed with data, including six appendices which amplify and detail the findings of the study.

According to the Waubra Foundation’s analysis (“Acoustic Engineering Investigation at Cape Bridgewater Wind Facility” 2/1/15),

The purpose of the investigation was simply to find out what was causing the symptoms and sensations, resulting in sleep disturbance and health damage, reported to Pacific Hydro between 2009 and 2014 by the residents of three homes sited between 600 – 1600 metres [from just over 1/3 mile to 1 mile] from wind turbines sited at the Cape Bridgewater Wind Project in Victoria, Australia. [see maps below]

In The Australian “Turbines may well blow an ill wind over locals, ‘first’ study shows” (1/21/15), Graham Lloyd reported :

Funded by wind farm operator Pacific Hydro, the study was conducted at Cape Bridgewater in southwest Victoria where residents have long complained about headaches, chest pains and sleep loss but have been told it was all in their minds.

There were several “firsts” to this study.

  • Cooper took a variety of measurements in and around the three homes during both times when the turbines were operating and when they were shut down–with the cooperation of Pacific Hydro.
  • The measurements went beyond standard dB(A), to capture harmonics peculiar to wind turbines as the blades pass by the stationary mast. This yielded new readings, branded by Cooper “wind turbine signature” or WTS.* Infrasound below the audible range was captured, as well.
  • The residents kept continuous diaries, recording their experience of noise (which can be heard), vibration (which can be felt), and sensations (which were considered to be reactions to infrasound). The diary entries were later correlated with recorded measurements.

Wicked Local Kingston Picks up Chronicle Story

February 2, 2015

click to watch the videoThe WCVB TV5 Boston news magazine, Chronicle, noted the issues raised by wind plants for turbine neighbors in Kingston (“Too Close for Comfort” 1/22/15).  Noise and strobing are the tangible effects, but lack of transparency in the siting process and in the production output is also cited as a factor in the piece.

Reporter Kathryn Gallerani revisited  the piece in “Channel 5 program focuses on Kingston wind” in Wicked Local Kingston (2/2/15), giving readers the quotes from the piece, which are absent from WCVB’s transcript.Doreen-Reilly-interview-Chronicle

“Our quality of life is important, and I don’t think the town of Kingston took the residents into consideration that would be the most affected by the turbine,” she said. “I don’t think anybody did it maliciously. I don’t think people realized what they were actually voting on. Even the people in charge didn’t realize what they were doing. They weren’t educated.”

Chronicle‘s J. C. Monahan interviewed wind neighbor Doreen Reilly and wind booster Tom Bott, Kingston’s Town Planner. Predictably Bott labeled suffers as being annoyed. Monahan offered push-back, “for people in that situation it’s more than an annoyance, it reduces their quality of life.” Neither brought up the technical/medical use of the term “annoyance” to mean severe impacts such as sleep disruption, headaches, nausea, vertigo and other health effects attributable to industrial wind turbines.

Memo to Gov. Baker: Stop New Wind Projects

January 11, 2015



In response to the Globe South’s question “Should the Baker administration support wind energy?” Joanne Levesque argued that

Our state’s energy policy should never sacrifice the rights of private property owners or promote public harm. Current support for wind power projects is premised on allowing harm to our neighbors. Violation of the law is not how a civil society should adopt solutions to climate-change challenges.

A resident of Duxbury, Levesque serves on the Wind Advisory Committee. She urged the Baker administration to

immediately do what 44 Massachusetts cities and towns have done in the past 10 years — that is to deny the construction of new land-based wind projects. The new administration should also do what Falmouth has been forced to do by a Barnstable Superior Court judge who ruled on the evidence: reduce the operational hours of existing turbines to protect their neighbors from further harm.

The pro/con discussion appeared in the Boston Globe’s metro South edition on January 10, 2015.

Bourne Meeting Reminded of Falmouth Effect

December 15, 2014

FGW-Plymouth“Haven’t we learned anything from the town of Falmouth?” asked John McMahon at Bourne’s Board of Health meeting on the wind project to be sited in neighboring Plymouth. His comments were reported in The Enterprise: “Bourne Residents Speak Out Against Plymouth Turbines” (by Michael J. Rausch on 12/12/14).

John T. McMahon of Morning Mist Lane in Buzzards Bay was outraged that Mr. Mann was even considering his project. Mr. McMahon held in his hand a report from the Falmouth Board of Health that showed 47 people suffering from health problems due to wind turbines.

According to the news report, the audience had plenty to say about potential harm from the proposed project beyond its compliance with BOH wind turbine siting regulations (quoted later in the post).

In an effort to deflect noise concerns, Keith Mann of Future Generation Wind, said the project will use newer turbines. This drew an online comment from Mark Cool, whose Firetower Road residence is impacted by the Falmouth turbines. In his post (Bourne Resident Deals Wind Developer “Falmouth Experience” Trump Card 12/12/14), Cool debunks assumptions that newer turbines are quieter.

The International Electrotechnical Commission [IEC ~ the international standards and conformity assessment body for all fields of electrotechnology] has sound rated ALL patented industrial wind turbines. The IEC-reported sound power levels range from 102dbA – 107dbA for industrial turbines. The IEC’s rating methodology IS NOT, in any way, shape or form, correlated to or distinguished by the age of the turbine.

The Plymouth project consists of four 476-foot, 2-megawatt Gamesa turbines with potential impacts on residents of Bournedale. In their Op-Ed in the Cape Cod Times, “Let’s not bargain with the devil,” (11/21/14), Lilli-Ann Green of Wellfleet and Yvonne Relin of Brewster urge Cape communities to get the facts before signing municipal power purchase agreements (“net metering”) that will allow the project to advance. Plymouth's Future Generation Wind impact zone

Bourne passed regulations for “Wind Energy Conversion Systems” to protect residents from turbine noise:

A. Noise.
Daytime: The noise generated by a WECS shall not exceed 6 dB(A) above ambient or and with a cap value of 65 dB(A) at the closest property line. The Board may allow a greater dB(A) where the applicant has demonstrated proven at a public meeting no inhabitants will be adversely affected.
Nighttime: The noise generated by a WECS shall not exceed 6 dB(A) above ambient and with a cap value of 40 dB(A) at the closest property line. The Board may allow a greater cap value of 65 dB(A) where the applicant has proven at a public meeting no inhabitants will be adversely affected.
B. Modulation.
The amplitude modulated noise measurable in overall A-weighted sound pressure level shall not exceed 4 dB peak to trough at the closest property line. A higher AAM may occur only of [sic] the applicant has demonstrated to the Board of Health that no inhabitants will be adversely affected.
