Ontario engineer develops new protocol for wind turbine noise measurement, tells international conference Ontario government procedures are missing noise problems
How badly were ratepayers hit? Millions upon millions for power produced out of phase with demand…
While the Canadian Wind Energy Association, the trade association for the wind power industry and vested interests, continues to maintain that wind power cannot be contributing to Ontario’s rising and unsustainable electricity bills, the facts indicate otherwise. The figures for April 2017 show wind power produced out-of-phase with demand, causing power from other, clean sources to be wasted, and wind power producers paid not to add power to the Ontario grid.
Here is Parker Gallant’s analysis.
The Independent Electricity System Operator or IESO’s 18 month outlook report uses their “Methodology to Perform Long Term Assessments” to forecast what industrial wind turbines (IWT) are likely to generate as a percentage of their rated capacity.
The Methodology description follows.
“Monthly Wind Capacity Contribution (WCC) values are used to forecast the contribution from wind generators. WCC values in percentage of installed capacity are determined from actual historic median wind generator contribution over the last 10 years at the top 5 contiguous demand hours of the day for each winter and summer season, or shoulder period month. The top 5 contiguous demand hours are determined by the frequency of demand peak occurrences over the last 12 months.”
The most recent 18-month outlook forecast wind production at an average (capacity 4,000 MW growing to 4,500 MW) over 12 months at 22.2%, which is well under the assumed 29-30 % capacity claimed by wind developers. For the month of April, IESO forecast wind generation at 33.2% of capacity.
April 2017 has now passed; my friend Scott Luft has posted the actual generation and estimated the curtailed generation produced by Ontario’s contracted IWT. For April, IESO reported grid- and distribution-connected IWT generated almost 703,000 megawatt hours (MWh), or approximately 24% of their generation capacity. Scott also estimated they curtailed 521,000 MWh or 18 % of generation capacity.
So, actual generation could have been 42% of rated capacity as a result of Ontario’s very windy month of April 2017, but Ontario’s demand for power wasn’t sufficient to absorb it! April is typically a “shoulder” month with low demand, but at the same time it is a high generation month for wind turbines.
How badly did Ontario’s ratepayers get hit? In April, they paid the costs to pay wind developers – that doesn’t include the cost of back-up from gas plants or spilled or steamed off emissions-free hydro and nuclear or losses on exported surpluses.
Wind cost=22.9 cents per kWh
For the 703,000 MWh, the cost* of grid accepted generation at $140/MWh was $98.4 million and the cost of the “curtailed” generation at $120/MWh was $62.5 million making the total cost of wind for the month of April $160.9 million. That translates to a cost per MWh of grid accepted wind of $229.50 or 22.9 cents per kWh.
Despite clear evidence that wind turbines fail to provide competitively priced electricity when it is actually needed, the Premier Wynne-led government continues to allow more capacity to be added instead of killing the Green Energy Act and cancelling contracts that have not commenced installation.
* Most wind contracts are priced at 13.5 cents/kilowatt (kWh) and the contracts include a cost of living (COL) annual increase to a maximum of 20% so the current cost is expected to be in the range of $140/MWh or 14cents/kWh.

“Assertions are complete nonsense … only wilful blindness would suggest that wind and solar are low cost”
Recently, energy analyst and occasional columnist for The Financial Post Parker Gallant wrote that the Canadian Wind Energy Association (CanWEA) was hitting back at allegations that wind power was contributing to Ontario’s rising electricity bills.
Ontario representative Brandy Gianetta said wind power was a low-cost energy source, and she referred to University of Waterloo professor Jatin Nathwani for support.
Trouble is, she was wrong.
Professor Nathwani took the time to correct CanWEA’s statements in an email to Parker Gallant, published on his Energy Perspectives blog today.
Here is Professor Nathwani’s email:
Dear Mr Gallant:
In your Blog, you have cited Ms. Giannetta’s post on CanWEA’s website on April 24, 2017 as quoted below:
Her article points to two articles that purportedly support the “myth” she is “busting,” but both require closer examination. She cites Waterloo professor Natin Nathwani’s, (PhD in chemical engineering and a 2016 “Sunshine list” salary of $184,550) article of March 6, 2017, posted on the TVO website, which supports Premier Wynne’s dubious claims of “a massive investment, on the order of $50 billion, for the renewal of Ontario’s aging electricity infrastructure.” Professor Nathwani offers no breakdown of the investment which suggests he simply took Premier Wynne’s assertion from her “Fair Hydro Plan” statement as a fact! It would be easy to tear apart Professor Nathwani’s math calculations — for example, “The total electricity bill for Ontario consumers has increased at 3.2 per cent per year on average” — but anyone reading that blatant claim knows his math is flawed!
First and foremost, the record needs to be corrected since Ms Giannetta’s assertions are simply incorrect and should not be allowed to stand.
If she has better information on the $50 billion investment provided in the Ministry of Energy’s Technical Briefing, she should make that available.
The breakdown of the investment pattern in generation for the period 2008-2014 is as follows:
Wind Energy $6 Billion (Installed Capacity 2600 MW)
Solar Energy $5.8 Billion (Installed Capacity 1400 MW)
Bio-energy $1.3 Billion (Installed 325MW)
Natural Gas $5.8 Billion
Water Power $5 Billion (installed Capacity 1980 MW)
Nuclear $5.2 Billion
Total Installed Capacity Added to the Ontario Grid from 2008-2014 was 12,731 MW of which Renewable Power Capacity was 6298MW at a cost of $18.2 Billion.
For the complete investment pattern from 2005 to 2015, please see data available at the IESO Website.
In sum, generation additions (plus removal of coal costs) are in the order of $35 billion and additional investments relate to transmission and distribution assets.
I take strong exception to her last statement suggesting that the 3.2 percent per year (on average) increase in total electricity cost from 2006 to 2015 in real 2016$. The source for this information is a matter of public record and is available at the IESO website.
Ms Giannetta’s assertion is complete nonsense because she does not understand the difference between electricity bill and generation cost. Let Ms Gianetta identify the “blatant flaw.”
As for the electricity bill that the consumer sees, there is a wide variation across Ontario and this is primarily related to Distribution.
The Ontario Energy Board report on Electricity Rates in different cities provides a view across Ontario:
For example, the average bill for a for a typical 750kWh home Ontario comes is $130 per month.
In Toronto it is $142, Waterloo at $130 and Cornwall at $106. On the high side is Hydro One networks is $182 and this is primarily related to cost of service for low density, rural areas.
Your Table 2 Total Electricity Supply Cost is helpful and correctly highlights the cost differences of different generation supply.
Only wilful blindness on Ms Giannetta’s part would suggest that wind and solar are coming in at a low cost.

In a recent interview, Ontario Energy Minister Glenn Thibeault spoke in defence of his government’s energy policies, which he admits have been responsible for escalating electricity bills and creating “energy poverty” in the formerly prosperous province.
The Minister claimed that his government didn’t self-promote the benefits of its policies often enough, and offered some public health figures as proof.
“When I talk about energy,” the Minister said, “we don’t [talk] about the fact we haven’t had a smog day in three years. Our air pollution hospitalizations are down by 41 per cent, deaths are down 23 per cent.”
Parker Gallant took the initiative to query the Minister’s office on the source of those dramatic figures and learned that whoever provided them to Mr. Thibeault for “talking points” had actually taken them from a report which in turn referenced another report, which had nothing whatever to do with energy and electricity generation in Ontario.
Here is the relevant excerpt:
These estimates include the impact of pollution originating in other parts of Ontario and the United States and represent a decrease of 23% in premature deaths and 41% in hospitalizations as compared with 2004 estimates. Air pollution in Toronto comes mainly from traffic, industrial sources, residential and commercial sources, and off-road mobile sources such as rail, air, and marine sources. Of these sources, traffic has the greatest impact on health, contributing to about 280 premature deaths and 1,090 hospitalizations each year…”
To be sure, air pollution is a major concern in public health, but for a Minister of the Crown to misappropriate figures to bolster policy in another area entirely is unacceptable, and deceitful.
We recall again the fact that two Auditors General for Ontario chastised the government for having implemented a green energy program including highly invasive wind power projects in quiet rural communities against their wishes, with no cost-benefit analysis. The truth about health benefits might have shown up, if a real independent analysis had ever been done.
“…in the public interest … to remove from the REA turbines … in Blandings turtle habitat”
The Environmental Review Tribunal released its long awaited decision on the remedies proposed by wind power developer WPD for its White Pines project in Prince Edward County Ontario to protect the endangered Blandings turtle and Little Brown Bat.
Relevant sections of the decision:
 In light of all of the circumstances, based on the evidence provided and taking
into account the purposes of the EPA in support of environmental protection and
renewable energy, the Tribunal finds that it is in the public interest to alter the Director’s
decision by amending the REA in part. The Tribunal finds that it is in the public interest
to add the Approval Holder’s proposed Condition L2 to the REA, but to alter that
condition by removing Tables 3-1 to 3-3, in the NRSI Plan. The Tribunal further finds
that it is in the public interest to remove from the REA the turbines proposed to be
accessed by the proposed upgraded secondary and tertiary municipal road segments
and by the intersections in Blanding’s turtle habitat, specifically Turbines 12, 13, 14, 15,
16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 and 29.
Condition J7.1. The Company shall implement the Mitigation Plan
for Operation of the White Pines Energy Project, dated July 21,
2016 prepared by Stantec Consulting Ltd., including:
1. Implement the monitoring and mitigation measures as
outlined in Table 2 of the Mitigation Plan;
2. Adjust cut-in speed to 5.5 m/s between sunset and sunrise
from May 1 to September 30 at all turbines for the operating
life of the Project; and
3. In the event of a mortality of a bat species that is a species
at risk, successively increase the operational mitigation as
detailed in Table 2 of the Mitigation Plan.
The question that remains is, with 60 percent of the project effectively removed, how can WPD meet its obligation to provide 75 percent of the power in its contract?
The entire project may have to be reformulated…it remains to be seen whether the company will opt to do that by using 4.1 MW turbines perhaps, or by finding other locations, but the company may have run out of time to do that.
The decision is here:ERT15068-White PInes
Here is a recording of lawyer Eric Gillespie’s closing remarks at the remedy hearing held in Wellington, last January. “The only remedy is to revoke [the approval]. … the result of mitigation will be to extirpate a species.”
As in, little or no understanding of the problems with wind turbine noise emissions.
On Friday, April 21, the Ministry of the Environment and Climate Change released a new protocol document intended for “assessing noise from wind turbines that have already been built. It is used by industry and ministry staff to monitor compliance.”
While in the absence of guidance for staff, and the complete lack of compliance audit information from wind power developers and operators, this is a step forward, the truth is, the protocol doesn’t change much.
- the protocol still relies on audible noise only, when many of the complaints registered with the MOECC concern effects that are clearly linked to other forms of noise
- the protocol does not take into account lower wind speeds, which is where problems are being experienced, particularly with newer, more powerful turbines
- there is no comment on any sort of transition between the protocol that existed before and this one
- the Ministry’s action in producing this protocol is an indication that they know they have a problem
- the description of Ministry response is a good step forward
- requiring wind power companies to actually have, and to publish, compliance audit documents could be a sign of expectations of greater accountability among the power developers/wind power project operators.
This table outlines the critical gaps in the new protocol document.
|Issue||Protocol Requirements||Actual Experiences|
|Wind Speeds||Assessment of noise at wind speeds between 4 m/s and 7 m/s||MOECC testing indicates problem noise starts below 3 m/s which is outside of wind speeds involved in the protocol.|
|Ambient Noise||Narrow time period assessed||Wide seasonal variations while wind turbine noise constant|
|Location||Only test outside of home||Very different inside noise conditions|
|Tonal Assessments||Uses criticized techniques||Narrow band analysis shows tonal noise present.|
|Resident Input||None||Resident concerns drive other MOECC procedures|
|Frequencies||Excludes Infrasound||Elevated levels of infrasound in homes|
The Ministry of the Environment and Climate Change needs to acknowledge that there is a problem with wind turbine noise, and accept that it must play a role as a government agency charged with protecting the environment and people in it — preparing an industry-led document may look like a positive step, but this document does not meet the needs of the people of Ontario forced to live with wind turbines, and their noise emissions.
Wind Concerns Ontario
“A careful reading of this paper shows that the conclusions are not supported by the data provided …”
A paper by Jalali et al was published in the journal Environmental Research last year, concluding that psychological factors contributed to distress and changes in sleep pattern, not the actual wind turbine noise emissions. Many people already living close to wind turbines were disappointed (not to say, astonished) by its conclusions, particularly those who trusted the research team and allowed them into their homes in the hopes of a meaningful and accurate research study.
Engineer and Ontario resident William Palmer did a detailed analysis of the Jalali paper; his comments have just been published by Environmental Research.
It remains a continuing disappointment that ideology (wind power is good and trumps all other concerns) seems to underlie research into the growing public health/environmental health issue associated with industrial-scale wind turbines and the noise emissions they produce. It is also disappointing that researchers continue to look for “psychological” factors instead of taking a public health approach to doing real-world investigation into a real-world health effect.
We say, BELIEVE the complaints from people. Then look for the cause of the problems.
The link to Mr Palmer’s comment is here.
Short-Communication: Revisiting conclusions of the report titled, “The impact of psychological factors on self-reported sleep disturbance among people living in the vicinity of wind turbines”.
The research report concluded, “It appears that self-reported sleep reported of participants may be associated to the indirect effects of visual and attitudinal cue and concern about property devaluation rather than distance to the nearest WT’s or noise as itself.”
Careful reading of the report shows that the conclusions presented are not supported by the data provided in the report.
MOECC admission of ‘tonality’ a step forward but more action needed
(C) Wind Concerns Ontario
Residents living near the K2 wind power project in the Township of Ashfield-Colborne-Wawanosh have received a report from the Ontario Ministry of the Environment and Climate Change following noise testing done at their property, Wind Concerns Ontario has learned.
WCO received a copy of the MOECC report and other correspondence from the residents, who are members of the coalition of Ontario community groups and individuals in Ontario concerned about the impact of wind turbines on the economy, natural environment, and human health.
The noise testing was done at their request, connected to complaints made to the MOECC about excessive noise and sound pressure or vibration being emitted from industrial-scale wind turbines at the K2 power project.
The MOECC report’s Executive Summary states that
Based on the results of the analysis, it is acknowledged that sound from the wind turbines was audible during the measuring campaign at levels that appear to exceed the applicable sound level limits, and based on C3 measurements conducted at a nearby receptor (the distance is about 1250 m from R876; where the same turbine(s) within 1500 m distance impact both receptors) it was further concluded that there is a possibility that sound from the nearby turbines could be tonal. To confirm compliance, it is recommended that a tonal audibility assessment and detailed noise audit be undertaken in accordance with Part D of the draft Compliance Protocol for Wind Turbines Noise, NPC 350, 2017.
This is remarkable as it is the first time MOECC supervisory staff have admitted to “tonality” in wind turbine noise emissions. And also because, in previous noise testing by the MOECC, the Ministry claimed results were “inconclusive” due to other noises such as birds chirping and tree leaf movement.
A tonal audibility assessment is a step forward.
Is it enough?
The Ministry needs to acknowledge that there is a problem with wind turbine noise emissions, and in the case of this particular report and recommendation, immediate action is required, including comprehensive testing including for infrasound which was excluded by the equipment used for these tests.
It is time for government to accept responsibility for its wind power program and the impacts on people who were given no choice but to live with them.
Wind Concerns Ontario
The sitting Liberal government persists in “green” ideology despite energy poverty, no environmental benefit from industrial-scale wind turbines
Sam Oosterhoff, MPP for Niagara-West Glanbrook, put forward a Private Member’s Bill in the Legislature yesterday, proposing the government halt all wind power approvals in unwilling host communities.
An excerpt from his speech:
Industrial wind turbines are one of the reasons people are facing a choice between heating and eating. Expensive and counterproductive power subsidies for turbines we don’t want or need have contributed to the soaring hydro prices that are among the greatest burdens the people of Ontario have to face.
Whether they are spending billions of dollars to stretch out future debt payments or handing out rich subsidies to industrial wind turbine operators, this government will always stick Ontarians with the bill.
I’m not just tilting at windmills like Don Quixote, but a comparison is in order. Cervantes, in his famous novel, wrote about a dreamer of no substance who could not perceive reality—sounds a lot like the Liberals and their hydro plan. This government’s scheme does nothing to address the root cause of the Ontario energy affordability crisis: the Liberals’ Green Energy Act. We call it the bad contracts act because it was designed to benefit Liberal corporate donors, and locks taxpayers into a 20-year contract for overpriced wind and solar power. It’s also for energy we don’t need.
Since 2009, Ontario has given away $6 billion—$6 billion—in surplus energy to US states. States that have lower energy costs than Ontario are getting electricity from us at discount prices. We’re giving businesses across the border a competitive edge over our own Ontario businesses. Truly, Premier Wynne is the best Minister of Economic Development the United States has ever had.
Speaker, I’d like to remind everyone that although the NDP also like to complain about high hydro costs and say that they too are on the side of local communities, they were complicit in setting the stage for industrial turbines being forced down the throats of rural municipalities across Ontario. The NDP joined the Liberals to pass the bad contracts act that enabled the government to sign contracts with big hydro companies that aren’t transparent and can’t be examined. Municipal governments also say that their planning authority was eliminated by this provincial legislation. …
The Minister of Energy has acknowledged that this government has made mistakes with the energy file. The Premier has acknowledged that there are serious issues on the energy file that her government is going to be working on. Yet they don’t seem willing to address the fundamental reasons behind those mistakes. Today, I’m giving them a chance, and I hope they’ll take up the chance that this government can make remedy. If they’re actually sorry, they will vote for this motion. If the Liberal government is actually willing to listen to rural residents, to listen to municipalities and to follow up on the words of their throne speech, I hope their caucus will vote in favour of my motion.
Several other MPPs spoke as well, including Jim McDonell, PC Energy Critic Todd Smith, and Michael Mantha and Gilles Bisson for the NDP.

Testing being done for audible noise alone–residents’ symptoms indicate other problems
Two Ontario municipalities are supporting the call for the Ministry of the Environment and Climate Change to do comprehensive testing for the full range of noise emissions from wind turbines.
Last night, Kincardine Council supported residents Norma and Ron Schmidt, who have been forced from their home because of adverse health effects from the noise and pressure produced by turbines near them, in sending a letter to the Ministry.
The situation echoes that of Port Elgin where hundreds of complaints have been filed with the Ministry about the turbine on the property owned by Unifor. The municipality of Saugeen Shores has repeatedly asked the Ministry to conduct the necessary investigations, to no avail.
