Proof of the need to repeal the Unfair Green Energy Act
Tuesday October 17, 2017 was a typical Ontario fall weekday with electricity demand relatively low.
Total Ontario demand for power was slightly over 335,000* MWh for the whole day, peaking at hour 19 (7 PM) at 16,318 MW, according to the IESO’s Daily Market Summary.
That hour has significance as during weekdays, it signals the time when off-peak hours start. That Tuesday, it also was the hour when the Hourly Ontario Electricity Price (HOEP) reached its high for the day, getting all the way up to $5.01/MWh or ½ cent per kWh.
All through the day the wind was blowing. Based on the IESO’s Generator Report and Capability and their “wind generation forecast” it could have produced just over 57,000 MWh — that could have met 17% of Ontario’s demand. IESO only accepted 20,900 MWh, however, and the other 36,100 MWh were curtailed or cut back.
The collective cost of the grid-delivered and curtailed wind generation over the 24 hours was almost $7.2 million, making the cost of the grid-accepted wind $344.50/MWh or 34 cents/kWh. Also because of a surplus of generated power, Ontario exported 38,200 MWh (almost double what IESO accepted from wind generators), principally to New York and Michigan — they had to pay them an average of $1.13 per MWh to take it.
All this makes it clear: Ontario’s electricity ratepayers don’t need any of wind’s intermittent and unreliable power, but are forced to pay for it anyway. To make matters worse, that power we subsidize gets delivered to our neighbours at negative prices. Those costs wind up on our electricity bills, too.
It’s time for Premier Wynne to stop the bleeding and kill the Unfair Green Energy Act.
