Ontario’s Industrial Wind Turbines Fall Flat When Actually Needed

According to IESO data, Hour 19 on May 14th was Ontario’s peak demand hour reaching a high of 17,758 MW and once again those IWT were missing.  At that hour they generated a miserly 335 MW or 1.8% of demand while representing almost 16% of total capacity.  It should be noted they also have “first-to-the-grid” rights meaning they rank ahead of all other generation due to their contracts with the province.  

At hour one (hour ending at 1 AM) when demand is amongst the lowest in any day and declining, those IWT were generating 1751 MW or almost 39% of their capacity with demand under 13,000 MW ie: less than the combined capacity (14,814 MW)  of nuclear (even without the 3,144 MW of Bruce shut for their planned Vacuum Building Outage) and hydro . 

Generating excess power when unneeded always reflects itself by causing the market price ie; the HOEP (hourly Ontario energy price) to be low when IESO sell it off to our neighbours in Michigan, NY and Quebec. At hour one the HOEP averaged $13.31/MWh (1.3 cents/kWh) whereas at hour 19 it averaged $78.66/MWh. The foregoing is a reflection of how IWT generation’s intermittent and unreliable nature has caused the price of electricity in Ontario and around the world to increase to unaffordable levels.

It is worth noting at Hour 1 Ontario’s natural gas plants were generating 127 MW and in Hour 19 generated 3,477 MW disclosing their reliability.

The facts emphasized above should be ones the OCAA should disclose to the 32 municipalities throughout the province who have told the Ontario Ministry of Energy to shut down all gas plants by 2030. The OCAA has also pushed for the closure of all our nuclear plants suggesting Quebec would supply us with cheap hydro. That claim is an illusion by the OCAA as Quebec doesn’t have the power, we would need to replace what nuclear and gas provide! 

We Ontarians and those inept municipal politicians should be thankful we have those natural gas and nuclear plants or we all would experience continuing backouts!

Pretty sure we all appreciate; lights on to lights off!
