Ontario’s Perfect Demonstration of Wind’s Intermittent and Unreliable Nature

A Short History about wind’s electricity generation arrival

“Scottish engineer and physicist James Blyth (1839-1906) was credited as the first to generate electricity by constructing a windmill attached to a dynamo to light his cottage in his home village of Marykirk, Scotland in 1887.  He offered to allow his current to be used to light the main street of the village, but superstitious residents reportedly considered the mysterious electric light to be “the work of the devil“!

The Ups and Downs of Industrial Wind Generation

 A day in the life of industrial wind turbines in Ontario

On November 11th Ontarians were treated to the up and down vagaries of IWT (industrial wind turbines) spread throughout the province. They did a great job exhibiting their spasms and inability to generate power when needed but cranked it out when unneeded. A few examples over the day follow!

Hour 1

At Hour 1, IESO forecast IWT would generate 3,936 MW but only accepted 3,253 MWh on the grid so we should assume the difference (683 MW) was curtailed at a cost of $120/MWh allocated to ratepayers.  The market price (HOEP) was 0.00/MWh over the hour as we supplied Michigan, New York, and Quebec with 2,428 MWh. The 2,428 MWh represented 74.6% of the above noted grid accepted IWT generation so clearly wasn’t needed but, we ratepayers picked up their costs of over $327,000.  To drive the point home IWT frequently generate power when its unneeded! Ontario’s peak demand in Hour 1 was only 12,591 MW and could have been easily supplied by nuclear and hydro alone but the “first-to -the-grid rights allotted to IWT companies usurps our other generation sources! Hydro at that hour generated only 3,307 MWh, their lowest hourly generation for the day!

Hour 4

Moving on to Hour 4 (hour ending at 4 AM) IESO reported it as the lowest Ontario peak demand hour (12,095 MW) for the day and those IWT were still humming and forecast to generate 2,938 MW. IESO accepted 2,718 MW (22.5% of demand) and sold off 2,497 MW (91.9% of accepted IWT generation) to the same Hour 1 buyers for the princely sum of $3.49/MWh generating $8,714.53 of revenue but it cost (assuming it was all IWT generation) us Ontarians $337,095.00 without including curtailed costs.

Hours 1 to 7

Hours 1 to 7 saw IESO forecast IWT generation of 19,866 MW (58% of their capacity) and 17,884 MW was accepted while exporting 16,422 MW (91.8% of IWT grid accepted generation). The HOEP average was $8.90/MWh for those 7 hours meaning if those exports were either all IWT generated power (very likely) or caused by them the net cost to Ontario ratepayers was: $1,963,000 (16,422 MW X $135 plus 1,982 MW [curtailed] X $120 minus 16,422 MW X $8.90) for those 7 hours!

Hours 8 to 19

As the day progressed Ontario peak hourly demand increased while generation from IWT fell and at Hour 18 they only supplied 267 MW or 1.5% of Ontario’s daily peak demand of 17,237 MW! IWT failure at that hour to provide generation meant “net imports” were 1,004 MW as we purchased power from Quebec and even some from Michigan.  We paid an average of $46.93/MWh for that imported power greatly exceeding the cost of our sales to them in the middle of the night when those IWT were generating power we didn’t need.  As IWT generation fell the HOEP market price climbed and from hours 8 to 19 averaged $50.12/MWh a vast improvement from the early morning prices.

Hour 17 and hours 20 to 24

IWT generation at Hour 17 was at its lowest for the day generating only 240 MW but it started to ramp up slowly and by hour 20 was generating five times what it generated at hour 17.  For hours 20 to 24 IESO accepted 10,357 MW as peak demand fell and exports climbed.  Needless to say, as demand fell over the final five hours IWT generation increased while the HOEP fell from $34.40/MWh during Hour 20 to $2.11/MWh in Hour 24 as our unneeded generation from those IWT climbed!

The “first-to-the-grid” rights granted to the IWT owners by the Ontario McGuinty/Wynne led government(s) continue to burden us ratepayers with costs as the foregoing clearly demonstrates! As it turned out November 11th, 2022, captured the intermittency and unreliable nature of IWT over a 24 hour period clearly demonstrating how they operate not just daily but, weekly, monthly and annually! 

Based on what Ontarians and many others around the world are currently experiencing, due to the unreliable and intermittent nature of those “windmills”, we should, perhaps reconsider the events from 135 years ago! Eco-warriors around the world have pushed to have IWT replace reliable electricity generation from fossil fuels in their push for “net-zero” so perhaps the label by the residents of Marykirk, Scotland in 1887 should be resurrected and applied to IWT but not the electric light.

Perhaps it really is the “work of the devil” posing as an eco-warrior out to save the world from “climate change” that brought on the push for those intermittent and unreliable IWT!

  1. What governments fail to understand is that electricity is not just a single homogeneous product. Its generation components vary hourly as does its price, so it is really 24 different products. All these products today have two generic generation categories: dispatchable (reliable) and non-dispatchable (intermittent). Thus when governments tell us that renewables are now less costly they fail to mention less costly at providing what products?

  2. Can we be assured that the additional industrial wind capacity contracted for under the “climate plan” will not be granted “first-to-the-grid” rights?
