On one day recently, for one hour, Ontario’s thousands of towering wind turbines delivered just one megawatt of power. And still, Ontario had a surplus that was sold off cheap.
May 27 was a Saturday which is usually a “low demand” day for electricity in Ontario, compared to weekday power demand and assuming weather patterns are close to average. The temperature on the recent May 27 was slightly below historic averages in Toronto; as people woke up and set about their activities that day, the demand for electricity built slowly.
According to the IESO’s (Independent Electricity System Operator) Daily Market Summary, Ontario demand peaked at 14,069 MW and averaged 12,751 MW (total Ontario demand was 306,024 MWh for the whole day). If anyone checked IESO’s “Power Data” page at, say, just after 11 AM, they would have noted demand was 13,208 MW at 10 AM and the HOEP (Hourly Ontario Energy Price) was indicating a negative price of -$4.00 /MWh. If one had also looked at the “Generator Output and Capability” and scrolled down to “Wind Total” they would have seen that under the heading “Output” the number appearing on the screen was “1”!
As in, one single megawatt of power.
About half the capacity of one ordinary wind turbine.
So, at 10 AM on May 27, 2017 the approximately 4,500 MW capacity of the more than 2,000 wind turbines installed throughout the province by the McGuinty/Wynne governments with lucrative, 20-year contracts, were delivering one megawatt of power.
And yet, to the best of my knowledge, Ontario didn’t experience a blackout or brownout because intermittent wind power generation was almost completely absent, nor did our emissions increase, as we got all the power needed from nuclear and hydro resources. In addition, the almost 9,000 MW of gas generation was idling, operating at an average of about 2% of capacity almost all day.
Despite wind only producing an average hourly output of 75 MW for the day and just the “1” for hour 10, Ontario still exported 43,584 MW of power at a cost to ratepayers of $5.6 million*.
Despite the lackluster performance of industrial wind turbines May 27 and on many other occasions, a visit to the home page of CanWEA still claims: “Wind is delivering clean, reliable and low-cost electricity”!
Perhaps with another 4,500 MW of capacity in Ontario, the industrial wind turbines may have delivered TWO MW of power at 10 AM on May 27?
*Cost estimate assumes the second IESO estimate of May’s Global Adjustment of $127.76 holds up.
The past few days presented a couple of conflicting news events that made you want to scratch your head in wonderment.
First was a CTV news item June 5 headlined “Wasted green power tests China’s energy leadership”. The article stated: “In western China’s Gansu province, 43 per cent of energy from wind went unused in 2016, a phenomenon known in the energy industry as ‘curtailment.’ In the neighbouring Xinjiang region, the curtailment figure was 38 per cent and in northeast China’s Jilin province it was 30 per cent. The nationwide figure, 17 per cent, was described by Qiao’s organization as ‘shockingly high’ after increasing for several years in a row.” It went on to say: “The problem threatens to slow China’s progress in clearing its air and controlling the greenhouse gas emissions that make it the top contributor to climate change.”
A CanWEA blog (Canadian Wind Energy Association) by Brandy Giannetta, also on June 5, was headlined: “Adding more wind to the Ontario grid: no problem!”
Ms. Giannetta made these claims:
“Ontario could reliably integrate about 16,000 megawatts of wind energy (which would be able to meet more than a third of electricity demand in the scenario studied).
The additional amount of electricity generation reserves required to back up that 16,000 MW of wind (beyond the reserve capacity already in the system) would be as small as 196 megawatts, or 1.2 per cent of the wind energy capacity.
Wind energy, which is now the least-cost option for new electricity generation available in Ontario, would avoid about $49 per megawatt-hour of production costs within the electricity system if it supplied 35 per cent of Ontario’s electricity demand.”
The claims made on the blog supposedly used information from a partially taxpayer-funded, three-year study released in July 2016 co-sponsored by CanWEA and Natural Resources Canada and carried out by GE Energy Consulting, a subsidiary of General Electric. (GE’s website claims “Our portfolio of turbines feature rated capacities from 1.7 MW to 3.8 MW (Onshore) and 6MW (Offshore), we are uniquely suited to meet the needs of a broad range of wind regimes.”) As one would expect there is a “legal notice” (disclaimer) at the start of the report which names CanWEA as their client.
Needless to say, the report is extensive but looking at the 62-page Section 1, Summary Report, I noted the following, suggesting CanWEA suggest the small “reserve capacity” of only 196 MW is required to back up the 11,000 MW of new wind capacity and could be integrated:
“1.11.9 Reduced Reserves from Conventional Generation — This sensitivity examined the impact of reducing the level of spinning reserves obtained from conventional generation resources (thermal and hydro). Instead the reserves could be obtained from demand response, storage devices, or other nonconventional resources. This approach could reduce curtailment during periods where conventional generation resources are dispatched to their minimum output limits.”
The suggested CanWEA small 196-MW “reserves” being all that would be needed is a huge “stretch goal” (to use a phrase once favoured by the ruling Ontario government) and highly improbable! It suggests dispatching existing “conventional generation resources” will allow wind to contribute a lot more of its intermittent and unreliable generation.
The same section contained a stumbling block in respect to containing further cost increases as it notes: “Production simulation results show no significant reduction in curtailment. This indicates that the system is not constrained by the commitment of conventional generation units for reserve services.”
What that means is, curtailment will remain as is, as long as ratepayers pick up the costs of constraining conventional generation. It infers industrial wind generation be treated as “base-load” with “first to the grid” rights! Somehow, CanWEA view the expensive: “demand response, storage devices or other nonconventional resources” along with dispatch of conventional generation as an unrelated cost ratepayers must pay for unreliable and intermittent generation from industrial wind turbines, yet they claim “wind is now the least-cost option”. This appears to be CanWEA’s contribution to the “Fair Hydro Plan” kicking wind’s integration costs to the ratepayers bills!
Now with two conflicting perspectives about IWT curtailment from China and CanWEA, let’s look at recent Ontario history sourced from IESO and Scott Luft’s Monthly Wind data.
IESO reported in their 2016 Year-End Data they dispatched 2,244,230 MWh “representing 19 per cent of the total amount of wind energy produced in the province.” So, 2% more than China’s “shockingly high” amount garnered no attention in Ontario! Dispatched wind in 2016 added approximately $270 million to the GA for undelivered power, and no doubt caused nuclear steam-off and spilled hydro adding additional costs to the GA pot.
Scott’s files contain TX (transmission connected) and DX (distributor connected) wind generation as well as what has proven to be relatively conservative estimates of “curtailed” generation. For the first five months of the current year, curtailed wind was 1,580,629 MWh, which represented 22.3% of grid delivered and curtailed wind. It looks like the current year will easily surpass the record amount dispatched in 2016 in MWh and percentage terms.
Combining the average costs of wind generated MWh along with dispatched MWh suggests an average cost of a kWh from industrial wind turbines for the first five months of 2017 was 17.5 cents /kWh and for May 2017 was 23.4 cents /kWh.
Those costs to Ontario ratepayers makes it relatively easy to understand Ms. Giannetta’s closing paragraph on her blog where the “we” in the following sentence suggests she is clearly speaking for the members of CanWEA!
“It’s increasingly obvious that we are only beginning to reap the benefits of wind energy in Ontario.”
Stumbling over the IESO weekly summary* for May 24th to May 30th came with a shocking discovery that the HOEP (Hourly Ontario Electricity Price) for the week had descended to a low of $1.05 /MWh (megawatt hour) or 0.11 cents /kWh (kilowatt hour).
As it turns out, there is probably nothing you could buy for eleven one hundredths of a cent except for what was surplus to Ontario’s electricity demand for the week.
If you were looking to buy power from Ontario while living elsewhere it was much better than a Boxing Day or Black Friday sale! During that week IESO exported 278,712 MWh to NY, Michigan, Quebec, etc., which could have supplied 1.6 million average Ontario households with their electricity needs for the whole week for 19 cents. Yes, you read that right! The 278,812 MWh cost Ontario ratepayers the GA (Global Adjustment) which IESO’s 2nd estimate for May suggests will be $127.76/MWh (12.8 cents /kWh)!
What that means is, Ontario’s ratepayers will pick up $35.6 million in GA costs reducing electricity rates for our neighbours. Our neighbours can use that cheap power to lure small and medium sized businesses to their state or province. The businesses being lured away provide employment for many Ontarians.
Now, so surprised was I by the foregoing I fired off an e-mail to my friend Scott Luft about the meager amount of the HOEP for that week. Scott quickly responded suggesting a look at the prior week which he said was even more egregious. So egregious, that the HOEP for the week of May 17th to May 23rd was negative at -0.48 /MWh or -0.5 cents /kWh. He closed with the thought provoking “free power is really expensive” alluding to wind and solar as a fuel having virtually no cost!
It turned out the 308,616 MWh exported to NY, Michigan, etc., for the week commencing May 17th required Ontario ratepayers to pick up almost the full costs of our surplus and unneeded** generation and to also pay our neighbours to take it off our hands. The cost of the latter was $148,134. and the cost of the generation based on the second IESO estimate of the GA for May was $39.4 million! Those exported 308,616 MWh were equivalent to the “average” consumption of 1.8 million Ontario ratepayers for one week. Those 1.8 million ratepayers if they lived in Ontario, unburdened by the GA costs, would have been paid .83 cents for their average weekly consumption.
Instead of a benefit, those ratepayers were obliged to pay 12.8 cents /kWh for power they didn’t consume and also pay $20.00 for their own “average” consumption of 172 kWh for the week.
In just two weeks of May Ontario ratepayers subsidized the generation and export of 587,328 MWh at a cost of $75 million (excluding costs of curtailed wind, spilled hydro, etc.) to ensure our grid was stable and not cause blackouts or brownouts.
What the foregoing highlights is the complete mess our various Ministers of Energy have made of Ontario’s electricity system by catering to the whims of the many unqualified environmental groups who have led our government down the path of contracting for intermittent and unreliable wind and solar generation at high rates to save the world without even so much as a cursory cost/benefit analysis.
Just those two weeks of May 2017 make it obvious: Free power is really expensive!
June 6, 2017
* IESO’s weekly summaries commence Wednesday running to Tuesday of the following week.
**Unneeded generation costs include: spilled hydro, curtailed wind, steamed-off nuclear and idling gas plants.
April brought high winds, record curtailment of wind power, and record low consumer demand. Wasted and exported power could have supplied half the homes in Ontario for a month.
The Independent Electricity System Operator (IESO) recently released their April 2017 Monthly Market Report with information on power consumption, market pricing, exports and a host of other data. What the April report revealed was Ontario’s average demand was low — so low that when energy analyst Scott Luft searched IESO’s records, he found the total demand for the month was a record low. He searched back to 1994, which is as far back as available.
The total demand reported by IESO for April 2017 was 9,788,614 megawatt hours (MWh): Ontario ratepayers are conserving, or we have lost many industrial clients, or both!
Another significant fact appearing on IESO’s website is that April was a pretty good month for Class A ratepayers. They consumed 21.9% of Ontario’s demand, but were only charged 11.4% of the Global Adjustment (GA), $965.7 million. Class B ratepayers (that’s you and me, and small businesses) were charged with paying 88.6% of the GA, but represented only 78.1% of Ontario’s demand.
Cost: $160 million for revenue of $14 million
The other disturbing fact about April was our net export sales of power. That totaled 1,311,120 MWh sold at an average price of $11.14/MWh for a revenue of just $14.6 million for power that cost ratepayers $160 million. The loss of $145.4 million for the month contributed to the GA total of $965.7 million.
That 1.3 million MWh of exported power — which you paid for — could have provided power for more than 1.7 million average Ontario households at a cost of 1.11cents/kWh or just $8.35 for the month! (Assuming average use of 750 kilowatt hours/kWh of electricity for the month.)
Reviewing the IESO stats provides relatively current information but it doesn’t disclose the source of the generation, or what caused the hourly Ontario electricity price (HOEP) to be so low. Did we, for example, have to curtail wind?
Wind power: wasted. Again.
For that information I depend on my friend Scott Luft, who keeps a monthly data file which includes not only actual industrial wind generation, but also an estimate (always conservative) of curtailed wind power which we pay for but isn’t delivered to the electricity grid. For the month of April 2017, wind power generated and curtailed (521,056 MWh) was 1,374,873 MWh, for a cost of approximately $182 million.
Curtailed wind in April was the highest on record since we began paying for it back in September 2013!
Here’s the fatal math:
net exports of 1.3 million MWh +
the 521,000 of curtailed wind = 18.7% of total Ontario demand.
Combined, the 1,832,176 MWh at the HOEP price of $11.14/MWh and 1.11 cents/kWh and what do you get? Enough power for more than 2.4 million average households (over 50% of all households in the province) with their average need for power at a cost of only $8.35 — for the whole month.
Why doesn’t Premier Wynne simply cancel the Green Energy Act and the contracts for projects not yet built?
Either math is a problem for the Premier or she doesn’t want to admit to another “mistake”!
May 28, 2017
*Please note the GA is the can Premier Wynne is “kicking down the road” under her “Fair Hydro Plan” where she will refinance assets the Province doesn’t own by getting Ontario Power Generation to accumulate the debt for the uncoming 25% reduction in our monthly bills for the next four years. Look forward to a reappearance of the DRC (Debt Retirement Charge) but on a bigger scale in 2021!
Compare power output from wind and the cost to consumers between 2010 and 2016 and we learn this: we’re paying more for intermittent wind power, produced out-of-phase with demand
In 2010, industrial wind turbines (IWT) in Ontario represented total installed capacity of approximately 1,200 megawatts (MW); they generated 2.95 terawatt hours (TWh*) of transmission (TX) and distributed (DX) connected electricity. The power from wind cost Ontario’s ratepayers about $413 million for those 2.95 TWh, about 2.1% of total 2010 consumption. The cost of IWT generation in 2010 was 3.1% of total generation costs (Global Adjustment [GA] + Hourly Ontario Energy Price [HOEP]) and represented 33.5% of “net exports”** of electricity to our neighbours in Michigan, New York, and others.
Wind was over 90% of exported power
Jump to 2016: wind turbines represented installed capacity of almost 4,500 MW, and generated and curtailed*** TX and DX connected electricity totaling 13.15 TWh. The cost to Ontario’s ratepayers jumped to $1,894.3 million — about 12.2 % of total generation costs. The 13.15 TWh of generation was 7.9% of Ontario’s total consumption but 94.9% of net exports.
The cost per kilowatt hour of electricity generated by wind in 2010 was 14 cents and in 2016 it had increased to 17.5 cents, despite downward adjustments to the contracted values between 2010 and 2016. That cost doesn’t include the back-up costs of gas generation when the wind doesn’t blow and we need the power, nor does it include costs associated with spilled hydro or steamed off nuclear, but it does include the cost of curtailed wind, which was 2.33 TWh in 2016 and just shy of total wind generated electricity in 2010.
In the seven years from 2010 to 2016, Ontario’s electricity ratepayers picked up total costs of $7.746 billion for 56.9 TWh of grid-accepted and curtailed (4.9 TWh) wind-generated electricity. The actual value given to those 56.9 TWh by the HOEP market was just shy of $570 million meaning ratepayers were forced to pick up the difference of $7.166 billion for power that wasn’t needed. The foregoing is based on the fact we have continually exported our surplus generation since the passing of the Green Energy Act and contracted for IWT generation at above market prices.
During those same seven years, Ontario had “net exports” of 85.95 TWh while curtailing wind, spilling hydro and steaming off nuclear. And, at the same time, we were contracting for gas plant generators that are now only occasionally called on to generate electricity yet are paid considerable dollars for simply idling!
Refinancing wind payments
As noted above the cost of wind generation in 2016 was almost $1.9 billion and represented 15.3% of the Global Adjustment pot. That cost was close to what was inferred in an Energy Ministry press release headlined: “Refinancing the Global Adjustment” but suggesting it was taxpayer owned “infrastructure”: “To relieve the current burden on ratepayers and share costs more fairly, a portion of the GA is being refinanced. Refinancing the GA would provide significant and immediate rate relief by spreading the cost of electricity investments over the expected lifecycle of the infrastructure that has been built.”
What’s really being refinanced is a portion of the guaranteed payments to the wind and solar developers who were contracted at above market rates! So, what is being touted as a 25% reduction includes the 8% provincial portion of the HST and a portion of annual payments being made to wind and solar developers for their intermittent (and unreliable) power.
Premier Wynne’s shell game continues!

Note: Special thanks to Scott Luft for his recent chart outlining the data enabling the writer to complete the math associated with this Liberal shell game!
* One TWh equals 1 million MWh and the average household in Ontario reputedly consumes 9 MWh annually, meaning 1 TWh could power 111,000 average household for one year.
** Net exports are total exports less total imports.
*** Ontario commenced paying for “curtailed” wind generation in September 2013.
How many homes could have benefitted from the excess power Ontario wastes, or sells off cheap?
Recently reading comments on an article related to the cost of wind power generation in Ontario, I was struck by a simple message.
The commenter had obviously visited the IESO “Data Directory” and reviewed one item labeled Intertie Flows; he observed that IESO had exported 3,000 MWh (megawatt hours) in an hour. He then observed that the exported power could have supplied 4,000 homes with free power for a month. (Here’s the math: 3,000 MWh equals 3 million kWh; the “average” Ontario household consumes 750 kWh per month, so divide the 3 million by 750 and the answer is 4,000.)
This simple fact has not been picked up on by the media and yet, it is an easy way to shed more light on Premier Wynne’s “mistake” and our rising electricity rates. The commenter also suggests going further and examining a full quarter to determine how many Ontario households would benefit from no exported power.
Excess wind and solar costs us
To be fair, while Ontario has frequently exported 3,000 MWh, we also import electricity generated elsewhere presumably at similar market prices. Those net exports or net imports (very infrequent for Ontario) are contained in the Intertie* hourly reports posted by IESO. Let’s look at the first three months of the current year.
To begin, IESO’s Monthly Market Reports for January, February and March of 2017 indicate Ontario’s “average net intertie schedule” for the first quarter of the current year totaled 2,909,000 MWh. While that was happening, industrial-scale wind turbines were generating over 3.9 million MWh in the same three months, and were also required (by IESO) to curtail (and be paid for) another 536,000 MWh. So, the wind power developers picked up about $620 million for those three months.
To make matters worse, the average of the Hourly Ontario Electricity Price (HOEP) received (via the traded market) over those three months was only $22.72 per MWh or 2.27 cents per kWh. That means Ontario received $66.1 million for the sale of the 2.9 million “intertie” MWh, while the average cost paid by ratepayers at 11.1 cents/kWh means the cost of those exports was almost $324 million.
Reducing power bills by 25% is peanuts—kill the contracts
Let’s go farther: if 1.3 million (28% of all residential households) of Ontario’s average ratepayers could have purchased those net exported kWh over the three months at the same price they were sold for, the 2250 kWh they consumed would have cost them $51 instead of the $250 they were billed. That would have reduced their cost of electricity by 390%. That makes Premier Wynne’s supposed 25% electricity bill reduction pale in comparison.
If the Premier really wants to lessen the burden on future ratepayer bills she should immediately cancel any wind and solar contracts that have not broken ground, and suspend any all future procurement of these unreliable and intermittent generation sources.
*Intertie is defined as an interconnection permitting passage of current between two or more utility systems.
