The chart below uses IESO data for nine (9) July days and clearly demonstrates the vagaries of those IWT (Industrial Wind Turbines) which on their highest generation day operated at 39.7% of their capacity and on their lowest at 2.3%!  As the chart also notes, our natural gas plants were available to ramp up or down to ensure we had a stable supply of energy but rest assured IESO would have been busy either selling or buying power from our neighbours to ensure the system didn’t crash. [Independent Electricity System Operator for Ontario, Canada]

The only good news coming out of the review was that IESO did not curtail any wind generation as demand was atypical of Ontario’s summer days with much higher demand then those winter ones.

Days Gone By:         

Back and shortly after the McGuinty led Ontario Liberal Party had directed IESO to contract IWT as a generation source; their “Annual Planning Outlook” would suggest/guess those IWT would generate an average of 15% of their capacity during our warmer months (summer) and 45% of their capacity during our colder months (winter). For the full year they would be projecting an average generation of 30% of their capacity and presumably that assumption was based on average annual Ontario winds!

The contracts for those IWT offered the owners $135/MWh so over the nine days contained in the chart below those 125,275 MWh generated revenue for the owners of $16,912,125 even though they only generated an average of 11.8% of their capacity.  They are paid despite missing the suggested target IESO used because they rank ahead of most of Ontario’s other generation capacity with the exception of nuclear power due to the “first-to-the-grid” rights contained in their contracts at the expense of us ratepayers/taxpayers!

Should one bother to do the math as to the annual costs based on the 15% summer and 45% winter IESO previously used it would mean annual generation from those IWT in the summer would be about 3.9 TWh and 11.7 TWh in the winter with an annual cost of just over $2.1 billion for serving up frequently unneeded generation which is either sold off at a loss or curtailed!

Replacing Natural Gas Plants with BESS:

Anyone who has followed the perceived solution of ridding the electricity grid of fossil fuels such as natural gas will recognize ENGO [Environmental Non-Governmental Organizations] have convinced politicians that battery energy storage systems are the solution!  Well is it, and how much would Ontario have needed over those nine charted July days? One good example is July 9^th and 10^th and combining the energy generated by natural gas from the chart over those two days is the place to start. To replace that generation of 221,989 MW with BESS units the math is simple as those BESS units are reputed to store four (4) times their rated capacity. Dividing the MWh generated by Ontario’s natural gas generators by four over those two days therefore would mean we would need approximately 55,500 MW of BESS to replace what those natural gas plants generated.  That 55,500 MW of BESS storage is over 27 times what IESO have already contracted for and add huge costs to electricity generation in the province driving up the costs for all ratepaying classes. The BESS 2034 MW IESO already contracted are estimated to cost ratepayers $341 million annually meaning 55,500 MW of BESS to the grid would add over $9 billion annually to our costs to hopefully avoid blackouts!

The other interesting question is how would those 55,500 MW be able to recharge to be ready for future high demand days perhaps driven by EV recharging or those heating and cooling pumps operating?  The wind would have to be blowing strong and the sun would need to be shining but, as we know, both are frequently missing so bring us blackouts seems to be the theme proposed by those ENGO and our out of touch politicians and bureaucrats!

Just one simple example as to where we seem to be headed
based on the insane push to reach that “net-zero” emissions target!

Extreme Examples of Missing IWT generation:

What the chart doesn’t contain, or highlight is how those 4,900 MW of IWT capacity are undoubtedly consuming more power than they are generating on many occasions and the IESO data for those nine days contained some clear examples but less than a dozen are highlighted here!

To wit:

• July 5^th at Hour 11 they managed to deliver only 47 MWh!
• July 7^th at Hours 8, 9, and 10 they respectively generated 17 MWh, 3 MWh and 18 MWh! 
• July 9^th at Hour 9 they delivered 52 MWh!
• July 12th at Hours 8, 9, 10 and 11 they respectively generated 33 MWh, 13 MWh, 13 MWh and 35 MWh. 
• July 13^th at Hours 9 and 10 they managed to generate 19 MWh and 39 MWh respectively! 

Conclusion:

Why politicians and bureaucrats around the world have been gobsmacked by those peddling the reputed concept of IWT generating cheap, reliable electricity is mind-blowing as the Chart coupled with the facts, clearly shows for just nine days and only looking at Ontario!

Much like the first electric car invented in 1839, by a Scottish inventor named Robert Davidson, the first electricity generated by a wind turbine came from another Scottish inventor, Sir James Blyth who in 1887 did exactly that. Neither of those old “inventions” garnered much global acceptance until those ENGO like Michael Mann and Greta arrived on the scene pontificating about “global warming” being caused by mankind’s use of fossil fuels!

As recent events have demonstrated both EV and IWT are not the panacea to save the world from either “global warming” or “climate change” even though both have “risen from the dead” due to the “net-zero” push by ENGO.

The time has come for our politicians to wake up and recognize they are supporting more then century old technology focused to try and rid the world of CO 2 emissions.  They fail to see without CO 2 mankind will be setback to a time when we had trouble surviving!

Stop the push and stop using ratepayer and taxpayer dollars for the fiction created by those pushing the “net-zero” initiative. That initiative is actually generating more CO 2 such as the 250 tons of concrete used for just one 2 MW IWT installation!   Reality Bites!
