Big hole in "decommissioning plan" for wind turbines, says writer

As an observer at the special wind turbine meeting in the Kincardine council chamber on Tuesday, April 5, I was astounded at the content of the Leader Resources Services Corp. presentation. 

This company would have us believe that “decommissioning is good business” and that after expenses, there would be a net profit from each turbine of $8,938. Exactly how naïve do they think we are? A quote from their presentation:

  • Material in turbines is valuable
  • > 250 tonnes steel per turbine
  • Copper, aluminum, gearboxes, transformers, etc.
  • Salvage value more than covers cost of decommissioning

The big hole that I was referring to, is the one that was previously occupied by the concrete and steel footing on which the turbine stood. There are estimates of more than 1,000 cubic metres of concrete required per turbine footing. Say it was half of that, 500 cubic metres of concrete has an approximate weight of 2,400 kilograms per cubic metre.

  • 500 x 2,400 = 1,200,000 kilograms

In pounds, that’s 2,640,000 pounds; in tons, that’s 1,320 tons. That does not include the steel that was pile-driven into the soil 30 metres deep. In the 40 turbines that were erected by Enbridge, 1,000 piles were reported to have been driven.

 

The cost of putting this land back together as it was, after these monoliths cease to function, would be astronomical. Unfortunately, we did not have the opportunity to ask what the projected price of broken concrete and rubble was.

If for one moment these corporations think they can continue to pull the wool over our eyes and treat us with such disrespect, they are very much mistaken.
