Vampire Turbines In July

I recently read an entry on Wayne Gulden’s Wind Farm Realities website reviewing some figures for the Vestas V82 – 1.65MW capacity industrial wind turbine. The statement that stuck with me was:

… when the wind doesn’t get above 3.5 m/s – typically there’s a MINUS 50kw of production. This is power that must be supplied from the grid just to keep the turbine in business. And 50kw seems to be what the turbine uses to stay alive in good weather. In the winter it gets slightly higher – the highest negative numbers were in the 80 kw range.

I decided to investigate the performance of an industrial wind turbine project in Ontario comprised of 110 of the Vestas V82 turbines; Enbridge’s Underwood turbines in Bruce County.
110 turbines potentially each drawing 50kW means that at times when all Enbridge’s turbines are still, the draw would be ~5.5MW. In the parlance of the Ministry of Energy, and the renewables lobby, a draw of 5.5 MW is enough to prevent power being provided to over 4000 homes.

In Ontario, we know that wind is least productive in July – so the topic of how much “parasitic” load is present when turbines are unproductive is particularly relevant here.

The turbines’ manufacturer, Vestas, produced a Life cycle assessment of the V82-1.65 MW (the LCA) showing “energy balance” is achieved in 7.2 months of production. The “energy balance” is how long the turbine will take to generate the amount of energy consumed in production and disposal.

Mothers Chat with Energy Minister Chiarelli

DSCN0760It was field day for Mothers Against Wind Turbines and the destination today was Babcock and Wilcox Nuclear Manufacturing Facility in Cambridge.

Energy Minister Bob Chiarelli was also at the facility and was available to speak to the Mothers and address their many concerns. Issues discussed included health, noise decibel levels, improper siting, financial and economic impact on Ontario, wind company contracts in  addition to how it infuriates  rural Ontario that the Liberals are appealing the Ostrander point decision.

Minister Chiarelli showed himself to be an excellent example of a Liberal “listener” but only time will tell if he follows company policy and refuses to hear. We Mothers made it clear that we are determined to protect our families, our children, and the best course of action for the minister and all Ontarians is to no longer support industrial wind facilities being built within our communities and province. Mr Chiarelli, although thoughtful and pleasant, continued to recite the usual Liberal propaganda and spin . Great job Mothers! Not only is it important to speak out for those whom our government now refuses to protect, but as always, to set an example for our children. And thanks to Bob Chiarelli who took ten minutes out of his busy day to speak with the Mothers. I hope your next stop later that day, touring the Canadian Solar Facility, was just as interesting and eventful.
