Rants about Ontario’s electricity system

Industrial Wind Turbines on Canada Day In Ontario

As is often the custom in Ontario on hot humid summer days, most of the IWT (industrial wind turbines) took the day off so the 4,800 MW of capacity they have was virtually silent.  Had they operated at 100% of capacity they would have delivered 115,000 MWh but instead they only managed to puff out 7,440 MWh and had 400 MWh curtailed (at 11 PM) meaning they operated at a level of capacity of 6.8% including the curtailed MWh.  As the morning broke at hour 9 AM they generated 8 MWh or 0.017% of capacity.  Fortunately, we didn’t need their power as nuclear, hydro and gas easily supplied our needs throughout the day even though total market demand reached 22,641 MWh and Ontario demand peaked at 19,342 MWh or 402,000 MWh for the full day.  Our net exports were north of 45,000 MWh which earned us ratepayers only about $750,000 while costing us close to $7 million.”
