McGuinty forced this hazard into our residential communities

  1. They had a minor problem this past winter too; freezing blades
    They were all amazed.
    But, they think it will ‘eventually’ work.
    They have experts looking into it.

  2. In an eight page letter I received from NextEra about the Conestogo Wind Energy Centre, they had a comment about tornadoes: “Wind turbines are designed to meet rigorous standards and can withstand high wind speeds.”

    It’s another half truth from the windies. If you’re reading this Ms. Fraser would you care to comment?

  3. The lightning issues with OntarioIWTs also involve ground to cloud lightning as well as branch lightning .
    Has the public been informed just what is a safe distance

      • Same article, “Lightning Exposure Of wind Turbines”
        “This also implies that 1.31% of Danish wind turbines will receive direct lightning strikes in a year.” “This compares well with observed direct strike rates of 1.33% . “with a flash density at 0.35 flashes/sq.km/year.
        Lightning flashes /sq.km/year for southern Ontario range from ~3.5-6 flashes/sq. km/year

      • With Ontario lightning flashes per sq.km/year in the ~3.5-6/sq.km/year is ~10-15 times higher than Denmark at 0.35 flashes/sq.km/year.
        Denmark 1.33% IWTs struck by lightning and Ontario could be in the range of at least 13% struck by lightning/year or at least 10 times greater than Denmark?

      • FROM PORTUGAL, “A Case Study of Risk analysis due to Lightning for Wind Power Plants”, http://www.icrepq/icrepq-08/332-rodrigues.pdf
        Section 1.,Introduction, “Results obtained are able to support the advantage for investors to take into account the lightning activity in regions where the wind power plant shall be located.” NOTE: INVESTORS NEED TO BE INFORMED OF LIGHTNING ACTIVITY. Ontario is NOT Europe when it comes to lightning activity.

    • Another Ontario lightning hot spot is along a line from the southern tip of Georgian Bay to southeast of Barrie. Maybe a good idea for people to copy these maps for future references.

    • “Lightning Exposure of Wind Turbines”, May 2006 by Dale Dolan,Charles Sao,Peter Lehn.
      http://www.ele.utoronto.ca/~lehn/conference_papers/CP5.pdf
      This paper deals with the risk of lightning damage to IWTs by direct lightning strike. Note that in Denmark the lightning flash density is 0.35 flashes per sq.km per year. Lightning strike/flashes /sq.km/year are very much higher in Ontario. So the risk of lightning strikes is much greater here.
      The risk of upward/ground to cloud lightning increases as a structure height exceeds 100 meters.

      • “Lightning Protection Optimization for Large Wind turbines with Methods-of-Moments” General Electric,Munich,Germany
        http://www.emss.de/downloads/pdffiles/kru04_p.pdf, Risk Managemnet Section
        This article has the math formula for calculating the average annual number of direct lightning flashes to wind turbines. One area of off shore Germany has 0.75 flash density

      • Now every community involved with IWT installations can do their own calculations for the risk of lightning strikes to wind turbines in their area. Just “plug” in the needed local data to the math formula/equation and do the calculations. No more taking the government’s word on this issue.

    • http://www.nrel.gov/docs/fy00osti/28604.pdf, “Lightning Activties in the DOE-EPRI Turbine Verification Program”. See, “Historical Wind Energy Lightning Risk” section.
      The modern era of wind energy development originated in LOCATIONS where lightning activity is MINIMAL. Nothern Europe & California. Denmark 10 thunderstorm days/year & California less than 4 thunderstorm days/year.

    • International Electrotechnical Commission/IEC founded 1906

  4. And there are wild lightening storms in west lincoln….does the receptor have any idea what 400 gallons of toxic gear oil spewed across a couple of acres on the land will cost to clean up. Not to mention if a fatality occurs. Who would put their family at risk in such a manner with a 50 storey lightening rod close to their home.

  5. Go after the landowners and the people that are selling and leasing land..it was up to them to do due diligence…that’s where all our court battles should be directed to

    • That’s an interesting thought – there are many interesting court challenges –
      over – ‘due diligence’ – that’s for sure!

  6. It’s True!

    Don’t forget to click on – comments – for the evaluation of the story – interesting!

    • Published July 18,2008, Marion Fraser,
      “I discovered I loved helping customers get the best value for their energy dollars” She must have changed her mind since then? Does she think customers get their best value from IWTs?

  8. The link to those pictures seems to have disappeared. Lincoln County Emergency Management does not have a web link.

    Local newspaper has a few pictures of farm damage.

    Sorry, The picture links are back. Just my suspicious mind.

  9. Well of course a turbine can’t withstand a massive storm!! Nothing can, just look at the Joplin tornado. The 2/3s of the town was flattened, even churches so why would a man made IWT be any different? I don’t even know why you are having this discussion.

    • We had our suspicions – thank you for confirming
      At least now, we know we’re not nuts.

    • Does anyone know the number of conventional power plants that have been wiped out by tornados?

    • Well, for starters Jef, the setbacks from roads for IWTs aren’t even topple distance…. the setbacks for billboards or a sugar shack are far more than a row of massive spinning electrical machines (that are prone to blade failure and flopping over). Yes we should be concerned.
