In Part 1 of this series, I dealt with two of the five claims CanWEA makes for industrial-scale wind power development in its October 11, 2018 blog post, “Five reasons why wind energy is Ontario’s best option for new electricity supply”.
Refuting those two claims for omission of facts was relatively easy.
Here are the details on the remaining three.
3. CanWEA claim: “Wind energy will be necessary if Ontario is to keep Ontario’s electricity supply reliable through the next decade.”
CanWEA says the IESO “forecast a need for significant new electricity generation, especially from 2023 onwards, as the Pickering Nuclear station shuts down, other nuclear units are being refurbished, and generation contracts expire.” Well, that is true as IESO did suggest a shortfall, but here are the facts: the forecast shortfall is 1,400 MW. The OPG Lennox generation station with 2,100 MW has a contract expiring that year. So the question is, will the contract be extended? I was recently taken on a tour of the Lennox facility where I observed they were in the process of refurbishing one of the four 525-MW units which suggests they anticipate a renewal of the contract. With the anticipated renewal the “need for significant new electricity generation” is simply a figment of CanWEA’s imagination.
This claim goes on to suggest: “New wind energy would help keep Ontario’s electricity supply reliable, as well as more affordable.” And, “Other jurisdictions around the world are proving this – for example, Denmark now produces more than 44 per cent of its electricity from wind turbines on an annual basis.” The Denmark example ignores the cost of residential electricity on Danish households which is the highest in Europe. Denmark’s household electricity price is 312.60 Euro/MWh or $471.10 CAD/MWh, based on current exchange rates.
Is CanWEA suggesting is that if Ontario’s ratepayers were paying 47.1 cents/kWh it would be affordable? That seems like a big stretch and would push many more households into energy poverty!
The same applies to the claim of it being “reliable.” As noted in a June 2017peer-reviewed report by Marc Brouillette, wind generation in Ontario presented itself when needed only 35% of the time. If one considers that wind’s annual generation averages about 30% of capacity, it is therefore “reliable” about 10.5% of the time it’s actually needed. (Note: IESO values wind generation at 12% in their forecasts)
4. This CanWEA claim suggests: “Wind energy provides many services to system operators to keep electricity supply flexible.” Their view of “flexible” fails to align with what the grid operator IESO would consider flexible. As Marc Brouillette’s report noted, “… wind output over any three-day period can vary between almost zero and 90 per cent of capacity.” That variance often requires clean hydro spillage or nuclear steam-off or the export of surplus capacity or full curtailment.
All of those actions cost ratepayers considerable money. Wind is unable to ramp up if demand increases and is the reason Ontario has over 10,000 MW of gas/oil plant capacity, with much of it idling in case the wind stops blowing or clouds prevent solar from generating. CanWEA needs to review the definition of “flexible.”
Another amusing statement under this claim is that: “Wind energy can also provide a suite of electricity grid services, often more nimbly and more cost effectively than conventional sources, helping to ensure reliable and flexible electricity supply. These services include: operating reserve, regulation, reactive support, voltage control, primary frequency response, load following, and inertia and fast frequency response.” The bulk of those “suite of electricity grid services” are requirements for any generators on the grid. The ones suggesting operating reserve, reactive support, load following and fast frequency support are really referencing the curtailment of wind generation as noted in the preceding paragraph.
5. CanWEA’s final claim is: “Wind energy is essential to reducing greenhouse gas emissions” and goes on to suggest: “Ontario has achieved a 90 per cent reduction in electricity sector greenhouse gas emissions over the past 15 years, and wind energy has been an important contributor. Wind turbines do not emit greenhouse gases, just as they do not pollute the air.” If CanWEA bothered to be truthful, the trade association would not claim “wind energy has been an important contributor” in reducing greenhouse gas emissions. If you review year-end data as supplied by IESO for the year 2004 and compare it to the data for 2018, you are obliged to reach the conclusion that wind generation played absolutely no role in the “90% reduction in the electricity sector greenhouse gas emissions.”
Ontario demand in 2004 was 153.4 TWh (terawatt hours) and in 2018 was 137.4 TWh representing a drop in demand of 16 TWh. Nuclear generation in 2004 was 77 TWh and in 2018 was 90.1 TWh for an increase in generation of 13.1 TWh. The drop in demand of 16 TWh, plus the increased nuclear generation of 13.1 TWh, equals 29.1 TWh. Those 29.1 TWh easily displaced the 2004 coal generation of 26.8 TWh!
Ontario didn’t need any wind turbines to achieve the 90 per cent reduction in emissions by closing the coal plants, and CanWEA was totally wrong to suggest wind generation played anything more than a very small role.
As the saying goes, “there are always two sides to every story” but if it doesn’t fit the message you wish to convey, you simply ignore the other side! CanWEA has done that consistently while ignoring the negative impacts of industrial wind turbines.
Here are just five:
1.Providing intermittent and unreliable generation,
2. Causing health problems due to audible and inaudible noise emissions,
3. Driving up electricity costs,
4. Killing birds and bats (all essential parts of the eco-system), and
5. Possible link to contamination of water wells.
I could list other negative impacts, but I would first invite CanWEA to attempt to dispel those five.
Needless to say, the anticipated response will be “crickets”!
