Wind power on two recent windy days cost Ontario electricity customers three times the current rate … and the surplus meant emissions-free hydro and nuclear was wasted

Two days last week in Ontario are real-world proof of the cost of wind power, no matter what the government or wind power industry spin tells you. Tuesday, December 5th and Wednesday December 6th were two very windy days, an excellent opportunity to examine both the power generation from industrial wind turbines in Ontario and their delivered cost of power to the grid.
The numbers for those two days:
$$$ IESO forecasts indicated that wind could have delivered 23.8% (177,100 MWh) of total Ontario demand (755,200 MWh) via the 4,200 MW of grid-connected wind capacity.
But wind turbines have a bad habit of generating power when it’s not needed (middle of the night, spring and fall) so the intermittent power must often be curtailed (constrained/wasted but paid for). It was!
$$$ The IESO curtailed 41.8% of their forecast generation meaning 74,000 MWh were not used!
Via the contracts in place with wind power companies, IESO is obliged to pay for both delivered and curtailed power at prices for grid-accepted power at $135/MWh and $120/MWh for curtailed power.
$$$ Quick math: the cost for grid-accepted wind on those two days meant Ontario ratepayers got charged approximately $22.8 million or $221.14/MWh for grid-accepted wind. That means it cost ratepayers 22.11cents/kWh (kilowatt hour), well above what the average time-of-use rates would be for the average Ontario ratepayer! The cost of the delivered wind power for those two days was almost three times the current levied* “average” cost of 8.22 cents/kWh, and 3.7 times the off-peak cost of 5.9 cents/kWh.
There’s more (sorry): be assured IESO instructed OPG to spill water over the hydro dams and Bruce Nuclear to steam off nuclear power — so power from our two reliable, emissions-free sources of power generation was also wasted. OPG and Bruce will be paid for that waste and the cost will be added to our bills. At the same time gas plants (backing up wind and solar) were being paid for idling.
Those two December days also saw sales of surplus power of 93,700 MWh to our neighbours in New York, Michigan, and others for pennies of the actual cost. In all probability, we recovered around 15% of their generation costs meaning, we bit the bullet for another $10/11 million.
Total: too much
Just the cost of the curtailed and grid-accepted wind and the losses on our surplus exports for those two days was $32/33 million for absolutely no benefit to any of us ratepayers. If every day of the year was like those two days last week, Ontario’s ratepayers would be shelling out over $6 billion annually, due to the abysmal planning and management of the electricity sector by the current Ontario government.
Imagine how far $6 billion would go to improve our health care system.
