While the wind power lobby claims it could supply as much as one-third of our power, the hot summer days tell a different story — wind is pretty much nowhere to be found
A post on the wind power lobbyist the Canadian Wind Energy Association/ CanWEA’s website about seven months ago (December 6, 2018) stated: “The Pan Canadian Wind Integration Study* – the largest of its kind ever done in Canada – concluded that this country’s energy grid can be both highly reliable and one-third wind powered.”
Based on the hot days of July 2, 3, and 4 we have just experienced here in Ontario, the “one-third” of wind generation required would have been 482,430 MWh meaning wind capacity would have to be quite a bit larger than the 4,486 MW* currently grid-connected.
On top of that, the wind turbines would have to operate well in excess of the level they operated at during those three days.
Over the three days, total electricity demand was high-averaging just under 483,000 MWh per day. While nuclear, hydro and gas provided almost all of the power (1.448 TWh) needed the 4,486 MW of grid-connected wind generating capacity contributed 12,056 MWh in total over those three days.
That output represented a meagre 0.83% of total demand.
What that suggests is this: operating at that level would require in excess of 86,000 MW of wind capacity (2.3 times Ontario’s existing total grid connected capacity) to simply meet the “one-third” claim.
It would be a big stretch to ever see them contribute the self-proclaimed “one-third” of power the wind power lobby claims.
Hot muggy summer days and very cold winter days when electricity demand is at its highest is generally when industrial wind turbines take the day off!
One-third wind powered would be the antitheses of a “highly reliable” grid.

**4,486 MW of capacity operating at 100% would produce approximately 323,000 MWh over three days
The recent headline on the website North American Windpower read, “CanWEA Applauds New Carbon Pricing: ‘A Great Day For Canada’ “!
The article below the headline, as one would expect, had a cheering section from Robert Hornung, the President of CanWEA as follows:
“This measure sends a clear signal to investors,” comments Robert Hornung, president of CanWEA. “Ensuring that new natural gas-fired electricity generation will have all emissions exposed to the price on carbon by 2030 means that more carbon-free options like wind energy and solar energy will be deployed instead of fossil-fueled electricity generation, creating thousands of jobs and bringing investments into Canadian communities while protecting our climate. This is a great day for Canada.”
Instead of luring investors with the hope of riches in the wind, one might hope that Hornung’s diatribe sends a clear message to politicians and those responsible for managing the electricity grid (in the provinces affected) that they shouldn’t buy into the rhetoric! The reason most provinces have gas plants is to ensure there is power available when the wind doesn’t blow and those turbines sit idle (those forced to live close to the noisy machines love when that happens).
Ontario has seen high demand in recent days as temperatures rose and air conditioners were fired up to cool homes and businesses. On July 2, total demand was 463,656 MWh and wind generation delivered to the grid from the approximately 4,500 MW of wind capacity in Ontario was 4,054 MWh over 24 hours or — that’s less than 1% of total demand.
While wind turbines were sleeping on that day, gas generators were required to fill in for them and supplied almost 34,000 MWh (7.3% of total demand).
In my view, all ratepayers (industrial, commercial and residential) should lobby the federal and (affected) provincial governments to alter regulations in respect to the “carbon tax” charge. The regulations should require both the wind and solar generators to produce power when required and if they are unable to do so, the applicable “carbon tax” should be charged to them during hours when producing power surplus to demand.
Presently that surplus generation is disposed of by either exporting it or curtailing it. Both of those actions currently come at a substantial cost to ratepayers. The regulation change would direct revenue from the charge applied to offset the additional cost ratepayers would be picking up from the carbon tax charge on gas generators when wind and solar are not generating needed power and they are called on to fill the gap.
To paraphrase CanWEA’s president, then a carbon pricing announcement would “send a clear signal” to the intermittent and unreliable wind and solar power generators that ratepayers are fed up with electricity rates that have soared in part due to costly and intermittent renewable wind.
That “carbon-free option” touted by Robert Hornung has cost ratepayers in Canada billions, to the benefit of mainly foreign owned companies.
Mild spring weather, breezy days are money-making combo for wind power corporations
As very recently pointed out, utility-scale wind power operators love the spring because it brings nice breezes that result in lots of generation for which they are paid. The bad news for Ontario electricity customers is that the power produced is generally not needed, but due to the wind power industry’s negotiated “first-to-the grid” rights, they must be paid regardless.
That was the case on May 8 and again the following day.
May 9 was another low demand day in Ontario as reported by IESO with only 337,700 MWh required to supply all of the province’s needs for electricity. IESO’s forecast for power generation from wind was about 79,400 MWh, which would have represented 23.5 % of total demand. However, a large part of it was forecast for low demand hours; no doubt that meant power from other relatively cheap sources of generation were dispatched off.
Low demand on a low demand day caused IESO to curtail 29,400 MWh (37.1%) of the forecast output and to sell off surplus generation to our grid-connected neighbours in New York, Michigan, Quebec, etc. The net exports of 41,600 MWh (rounded) sold to those buyers represented 83% of the accepted “output” of wind power.
In other words, Ontario didn’t really need any wind power!
The net exports were worth $3.70 per MWh (average of the Hourly Ontario Electricity Price or HOEP for the day) meaning they produced total revenue for Ontario of approximately $154,000.
So, you might ask, how much wind generation cost Ontario ratepayers for the day?
The 29,400 curtailed MWh at the $120/MWh IWT operators get paid was $3.528,000 and adding in the cost of the 50,000 MWh actually accepted at $135/MWh adds another $6,750,000 to the cost of wind. That brings the total cost of wind for that spring day to $10,124,000 if we deduct the $154,000 generated by the sales of our net exports.
Ten million paid, $150,000 recouped–makes sense doesn’t it?
So, wind power on May 9 cost Ontario ratepayers $202.48/MWh or 20.2 cents/kWh. That doesn’t include any of the other costs its generation may have caused such as spilling cheap hydro or steaming off cheap nuclear. To top it off, most of the day’s wind power generation, if exported, at an average price of $3.70/MWh means a loss of $198.78 for every megawatt hour sold.
The “average” Ontario ratepayer would love to be able to buy the 9 MWh they consume in a year at those bargain basement prices of $3.70/MWh. Imagine: it would cost them $33.30 for a full year’s electricity needs. I’m confident our small and medium-sized businesses would also love the opportunity to pick up some of that cheap electricity, instead of being forced to pay for expensive, intermittent and unreliable wind and solar generation!
It’s time to sort out the mess created by the McGuinty/Wynne governments in respect to the electricity file.
If it isn’t, Ontario will continue to be stuck with climbing above-market electricity prices until the wind and solar contracts finally end.
Most Canadians love Spring simply because the snow is melting and that signals the summer is coming.
Ontario’s wind power developers love Spring, too! They know the wind will blow much stronger than in the hot summer weather and that means, their generation output will climb.
The fact the wind power lobby negotiated “first to the grid” rights with the Ontario government under Premier Dalton McGuinty means most of them will be paid 13.5 cents/kWh for whatever they produce, whether it is needed or not.
For example, May 8 was a day when the breezes were brisk throughout Ontario and the industrial-scale or utility-scale wind turbines were busy generating lots of power. The IESO (Independent Electricity System Operator) reports hourly on both the forecast for wind generation, as well as the actual output. That day, wind could have provided as much as 26% of total Ontario demand for power. But here’s the important fact: the total Ontario demand on an early May spring day is not what it is in the heat of summer or the cold of winter and that was the case on May 8. Total Ontario demand was only 322,000 MWh for the day.
Money for nothing
Because of the low demand, about 36% (30,400 MWh) of IESO’s forecast for wind power generation looks as though it was probably curtailed (paid for but not used) and the wind power operators were paid $120/MWh. That means, Ontario’s electricity ratepayers paid almost $3.7 million for nothing. Zero.
The output actually accepted into the grid was just over 54,000 MWh, which cost ratepayers about $7.3 million. Coupled with the curtailment costs, that meant each kWh of wind “grid-accepted” cost 20.3 cents/kWh.
We should also assume that Ontario was probably spilling hydro or steaming off nuclear due to low demand, which would further drive up that price.
As if this information isn’t enough of a downer on a nice spring day, the HOEP (Hourly Ontario Energy Price), or what is referred to as the “market price,” was noted in their daily summary at an average of $1.75/MWh.
And the very next day …
Ontario’s demand was so low so we didn’t need any wind generation May 9, so IESO had to sell it off at the market price to U.S. and other grid-connected operators. The surplus demand of just under 44,000 MWh (81% of grid-accepted wind generation) was sold at $1.75/MWh generating total revenue of $77,000 but cost ratepayers in the order of $6 million.
This all simply demonstrates why the Global Adjustment charge keeps climbing. If the loss of $6 million daily for just the cost of exporting our surplus energy occurred every day of the year, it would represent in excess of $2.1 billion annually as a cost to Ontario ratepayers.
The time has come to fix this weird situation created by the former Ontario government.
More work to be done to get Ontario electricity bills down
In the campaign before last year’s election in Ontario, Doug Ford promised to cut hydro bills by 12 per cent if his party won. He said it would be on top of a rate reduction (25% under the Fair Hydro Plan/FHP) from the governing Liberals, whose plan he had repeatedly criticized.
He also said he would cut rates through a variety of measures that would save the average ratepayer $173 a year. When asked about their plans in respect to the FHP he said, “We’re going to be reviewing that. That was, as far as I’m concerned, the wrong thing to do, borrowing down the future and the only people who are going to pay for it is our children, our great-grandchildren.”
He also said he would give ratepayers the dividends from the government’s share of the partially privatized Hydro One.
Since being elected with a majority, the Ontario PC Party has often issued press releases suggesting “promises made, promises kept” but so far, we haven’t heard those words uttered in respect to the electricity file.
IESO reports are now available for the first three months of 2019, so we can compare the quarter with 2018 under the previous government to see if any progress has occurred.
To begin, if you look at the IESO report reflecting the “Variance Account under Ontario’s Fair Hydro Plan” you can discern the dollars being deferred went from $410.5 to $496.6 million, a jump of $86.1 million or 21%. That is money Ontario ratepayers will have to pay back in future years! The second quarter could be just as bad: Scott Luft has estimated April 2019’s combined HOEP (Hourly Ontario Energy Price) and GA (Global Adjustment) will set a new record high.
So, let’s look at Hydro One’s dividends to determine how far they would go to achieving the 12% reduction. The December 31, 2018 annual report for Hydro One shows dividends paid of $518 million to shareholders, so the 47% ownership of Hydro One by the province would represent $243 million! If one than does the math for the promised annual average residential ratepayer saving of $173 the amount needed is about $807 million ($173 X 4,665,055 ratepayers = $807 million) for a shortfall of $564 million. Adding the additional FHP $86.1 million for the 2019 first quarter puts the shortfall at $650.1 million — so far.
For the first quarter of 2019, Ontario total electricity demand including net exports (exports minus imports) increased by 392 GWh (gigawatt hours) with Class A ratepayers increasing consumption by 486 GWh and Class B by 217 GWh while net exports declined by over 300 GWh. The weighted average of the GA and HOEP as reported by IESO on April 30th of each year climbed from $103.80/MWh in 2018 to $110.67 in 2019 a gain of $6.87/MWh or 6.6%. Multiplying the $6.87/MWh by Class B consumption of 25,628,600 MWh in the first three months of 2019 comes to approximately $44 million. That is about $42 million shy of the $86.1 million increased transfer to the FHP over the 2018 transfer. (We must assume, as frequently happens, IESO made an adjustment to the prior month’s transfer and that is the reason for the difference.)
In specifically examining wind generation and curtailment from Scott Luft’s post it appears year over year grid-accepted wind declined by 40,000 MWh and curtailed wind dropped 66,000 MWh. What that suggests is that the increase in costs is a reflection of the rate increases granted by the OEB to OPG for their nuclear generation at Darlington and Pickering. This marks the first time over a long period when increased costs cannot be blamed on either wind or solar generation or both!
The foregoing 2019 first quarter results may present a major road block for Premier Ford in achieving his “promise made, promise kept” catchphrase in respect to the energy file.
Last December, former Minister of Energy Glenn Thibeault, was testifying at a committee hearing and responded to a question on the portfolio as follows: “There was lots that was happening on the file, and I was still learning it, right? As I said earlier, I was drinking from a thousand firehoses. Not that I’m trying to minimize the complexity of the file, but there was lots for me to learn and, at the same time, trying to find ways to reduce rates was, I think, the most important thing.”
Perhaps that point should be borne in mind by the current Minister, under Premier Ford. There are ways and means of reducing upward pressure on electricity costs, but so far Greg Rickford, Minister of Energy, Northern Development and Mines seems to have missed them or is still trying to digest the complexities of his portfolio.
My advice: Start with the cancellation of the Nation Rise 100-MW wind power generation project which will eliminate over $400 million from future electricity bills. And for those living with industrial wind turbines in rural Ontario, ensure they are in compliance with audible and inaudible noise regulations! Consultation with the Minister of the Environment, Conservation and Parks to ensure the regulations are followed would go a long way to reducing costs.
Minister Rickford could also consult with some external experts and find out what can be done to reduce costs, beyond getting rid of the “$6 million dollar man” from Hydro One!
Refuting those two claims for omission of facts was relatively easy.
Here are the details on the remaining three.
3. CanWEA claim: “Wind energy will be necessary if Ontario is to keep Ontario’s electricity supply reliable through the next decade.”
CanWEA says the IESO “forecast a need for significant new electricity generation, especially from 2023 onwards, as the Pickering Nuclear station shuts down, other nuclear units are being refurbished, and generation contracts expire.” Well, that is true as IESO did suggest a shortfall, but here are the facts: the forecast shortfall is 1,400 MW. The OPG Lennox generation station with 2,100 MW has a contract expiring that year. So the question is, will the contract be extended? I was recently taken on a tour of the Lennox facility where I observed they were in the process of refurbishing one of the four 525-MW units which suggests they anticipate a renewal of the contract. With the anticipated renewal the “need for significant new electricity generation” is simply a figment of CanWEA’s imagination.
This claim goes on to suggest: “New wind energy would help keep Ontario’s electricity supply reliable, as well as more affordable.” And, “Other jurisdictions around the world are proving this – for example, Denmark now produces more than 44 per cent of its electricity from wind turbines on an annual basis.” The Denmark example ignores the cost of residential electricity on Danish households which is the highest in Europe. Denmark’s household electricity price is 312.60 Euro/MWh or $471.10 CAD/MWh, based on current exchange rates.
Is CanWEA suggesting is that if Ontario’s ratepayers were paying 47.1 cents/kWh it would be affordable? That seems like a big stretch and would push many more households into energy poverty!
The same applies to the claim of it being “reliable.” As noted in a June 2017 peer-reviewed report by Marc Brouillette, wind generation in Ontario presented itself when needed only 35% of the time. If one considers that wind’s annual generation averages about 30% of capacity, it is therefore “reliable” about 10.5% of the time it’s actually needed. (Note: IESO values wind generation at 12% in their forecasts)
4. This CanWEA claim suggests: “Wind energy provides many services to system operators to keep electricity supply flexible.” Their view of “flexible” fails to align with what the grid operator IESO would consider flexible. As Marc Brouillette’s report noted, “… wind output over any three-day period can vary between almost zero and 90 per cent of capacity.” That variance often requires clean hydro spillage or nuclear steam-off or the export of surplus capacity or full curtailment.
All of those actions cost ratepayers considerable money. Wind is unable to ramp up if demand increases and is the reason Ontario has over 10,000 MW of gas/oil plant capacity, with much of it idling in case the wind stops blowing or clouds prevent solar from generating. CanWEA needs to review the definition of “flexible.”
Another amusing statement under this claim is that: “Wind energy can also provide a suite of electricity grid services, often more nimbly and more cost effectively than conventional sources, helping to ensure reliable and flexible electricity supply. These services include: operating reserve, regulation, reactive support, voltage control, primary frequency response, load following, and inertia and fast frequency response.” The bulk of those “suite of electricity grid services” are requirements for any generators on the grid. The ones suggesting operating reserve, reactive support, load following and fast frequency support are really referencing the curtailment of wind generation as noted in the preceding paragraph.
5. CanWEA’s final claim is: “Wind energy is essential to reducing greenhouse gas emissions” and goes on to suggest: “Ontario has achieved a 90 per cent reduction in electricity sector greenhouse gas emissions over the past 15 years, and wind energy has been an important contributor. Wind turbines do not emit greenhouse gases, just as they do not pollute the air.” If CanWEA bothered to be truthful, the trade association would not claim “wind energy has been an important contributor” in reducing greenhouse gas emissions. If you review year-end data as supplied by IESO for the year 2004 and compare it to the data for 2018, you are obliged to reach the conclusion that wind generation played absolutely no role in the “90% reduction in the electricity sector greenhouse gas emissions.”
Ontario demand in 2004 was 153.4 TWh (terawatt hours) and in 2018 was 137.4 TWh representing a drop in demand of 16 TWh. Nuclear generation in 2004 was 77 TWh and in 2018 was 90.1 TWh for an increase in generation of 13.1 TWh. The drop in demand of 16 TWh, plus the increased nuclear generation of 13.1 TWh, equals 29.1 TWh. Those 29.1 TWh easily displaced the 2004 coal generation of 26.8 TWh!
Ontario didn’t need any wind turbines to achieve the 90 per cent reduction in emissions by closing the coal plants, and CanWEA was totally wrong to suggest wind generation played anything more than a very small role.
As the saying goes, “there are always two sides to every story” but if it doesn’t fit the message you wish to convey, you simply ignore the other side! CanWEA has done that consistently while ignoring the negative impacts of industrial wind turbines.
Here are just five:
1.Providing intermittent and unreliable generation,
2. Causing health problems due to audible and inaudible noise emissions,
3. Driving up electricity costs,
4. Killing birds and bats (all essential parts of the eco-system), and
5. Possible link to contamination of water wells.
I could list other negative impacts, but I would first invite CanWEA to attempt to dispel those five.
Needless to say, the anticipated response will be “crickets”!
Too bad the facts show that actually, wind power isn’t needed in Ontario
The trade association and lobbyist for the wind power development industry, the Canadian Wind Energy Association (CanWEA), loves to provide its audience with information that only shows them in a good light. Their audience, “environmental” organizations and gullible politicians are easily sold.
Once again CanWEA has put the spin out.
A recent short post is titled “A Canadian Success Story” and it claims “Wind energy met approximately 6 per cent of Canada’s electricity demand in 2017 – and more than that in jurisdictions such as P.E.I. (28 per cent), Nova Scotia (12 per cent), Ontario (8 per cent), Alberta (7 per cent) and New Brunswick (7 per cent).”
It is curious as to why CanWEA would have used 2017 as their “success story” as it was an expensive one for Ontario’s ratepayers. Wind generation, the curtailment of excess generation, the need for backup gas plants, and the inability of wind to deliver actual power when needed, all played a significant role in continuing to drive up costs for Ontario electricity consumers.
Power arriving on the grid when demand was low was a big factor in the creation of the Fair Hydro Plan by the former government. IESO reported grid-connected wind delivered 9.2 TWh (terawatt hours) which was only 6.4% of total grid-connected generation — not the 8% claimed by CanWEA. Another 3.3 TWh of wind generation was curtailed in 2017 which added costs.
The 9.2 TWh delivered to the grid cost ratepayers $1,242 million and the 3.3 TWh curtailed added another $396 million, bringing the total cost of wind generation to Ontario’s ratepayers to $1.638 billion or 17.7 cents/kWh! If spilled hydro of 6 TWh and 1 TWh of steamed-off nuclear caused by wind due to surplus baseload generation (SBG) conditions, their costs of about $330 million bring the total cost of wind generation to $1.968 billion. And that is without gas plant idling costs for when wind is absent.
The total costs for all grid-supplied electricity in 2017 amounted to approximately $16 billion. So, the cost of wind power generation, along with the wasted hydro and nuclear, represented about 12.3% of all costs for 6.4% of their grid-accepted generation. If costs of our exports were included, wind generation effects on our electricity bills would be even higher. In 2017, nuclear and hydro supplied 97.1% of Ontario’s demand; with the spilled (wasted) hydro of 6 TWh and the 1 TWh of steamed-off nuclear, they could have supplied 102%.
In other words, wind wasn’t needed.
Scanning stats for a couple of months in 2018 shows that during the hot and high demand summer months of July and August, wind generation does what it generally does — falls flat. Data supplied by Scott Luft and the IESO monthly summaries shows wind provided only 4% of Ontario’s demand in July and 4.4% in August. In May 2018, a low demand month, grid-connected wind supplied 5.7% of Ontario demand. It could have supplied 9.1%, but almost 40% of what it could have generated was curtailed due to the month’s low demand.
What this all demonstrates, again, is the intermittency and unreliability of power from wind turbines. Wind power forces ratepayers to simply hand out money without any benefit.
Our politicians need to recognize spin when they see it, and understand that wind turbines provide almost no value in reducing emissions, or providing a reliable supply of electrical power.
IESO wants residential ratepayers to “Set the mood”
It’s true! Ontario’s Independent Electricity System Operator (IESO) in a recent posting on their SaveOnEnergy site suggested we “Cut the lights and light some candles to set the mood for a cozy evening.”
IESO spends approximately $400 million annually on conservation initiatives, and they come up with this? They even go so far as to describe the event as a “Hygge, a Danish word: (pronounced hue-guh not hoo-gah) used when acknowledging a feeling or moment, whether alone or with friends, at home or out, ordinary or extraordinary as cosy, charming or special.”
I personally find it ironic that the word chosen by IESO is Danish. Denmark is where electricity prices for residential homes is the most expensive in Europe* at EURO per kWh of 0.3126 or Canadian 0.48 cents per kWh. Doesn’t that make all Ontario residents feel cosy!
Denmark is home to VESTAS and their product line is exclusively wind turbines. Vestas employs over 24,000 people which makes them one of the 10 largest employers in the country. Vestas’s website claim they have installed 97 GW (97,000 MW) of industrial wind turbines (IWT) globally. All those noise-emitting, bird- and bat-killing, intermittent and unreliable wind turbines might make the Danes “cosy” but somehow I doubt it, with the price they are paying for electricity.
The IESO post suggests we: turn off the phone, unplug appliances and devices, eat comfort food and use energy-efficient cooking methods like a pressure cooker! ** The message to the reader goes on to suggest pulling on wool socks and using our favourite blanket to get cosy and then to “get lost in the moment” by reading our favourite book!
IESO should stop the wasted spending on conservation efforts of this ilk. Does IESO not understand we are all billed monthly for our cost of electricity usage and have been doing our best to “stay cosy”? For many it has been an effort to simply avoid energy poverty.
Stop lecturing us, stop wasting our money and focus your efforts on managing the grid in a manner that will reduce the costs of electricity.
An eye-opening tour of the Lennox plant in Eastern Ontario leads to starting calculations, too
Back in late May and just before the Ontario provincial election, I wrote a “what if” post titled; “If I were Ontario’s new Minister of Energy …” which was suggested how I would undertake to reduce the costs of electricity.
So far, a few of my recommendations have actually happened.
I won’t linger over the enacted or missed ones but I will focus instead on my suggestion that we close the “Lennox oil/gas plant in Napanee/Bath with a capacity of 2,200 MW that is never used.”
I received an invitation to tour the Lennox plant and I accepted! The tour was led by John Hefford, VP Regional Operations-Eastern Region, who has responsibility for not only Lennox but for all the hydro generating facilities located in the eastern part of Ontario, which (including Lennox), totals about 4,800 MW — that’s about 30% of OPG’s total capacity.
Driving toward the Lennox plant one can’t help but notice, in the distance, the industrial wind turbines (IWTs) recently built on Amherst Island (“owl capital” of North America). That project is considered one of the most divisive wind power projects ever awarded a contract by IESO under the McGuinty/Wynne governments.
The tour combined with a takeaway “Overview” of Lennox was truly enlightening. The most noteworthy bits of information picked up were related to the ability of each of the four 525-MW turbines to ramp up quickly from their minimum load point of only 28 MW or 5%. To put that into perspective, the other gas plants operating in Ontario are mainly CCGTs (Combined Cycle Gas Turbines) and they have to idle at minimum loads that are six to 14 times higher.
The ramping load point at Lennox logically translates to much lower emissions than the units added to Ontario’s grid(s) backing up industrial wind turbines (IWT) and solar under the FIT (feed-in-tariff) program.
The other significant difference between the CCGTs and single-cycle Combustion Turbines (CTs) is in respect to idling costs: for Lennox the cost is about $4,200 MW per month versus CCGT generators with costs of $10,000 MW per month to $20,000 MW per month, and CTs which average about $10,000 MW.
Another impressive piece of information picked up on the tour is the ability of the units to operate on either natural gas or residual oil (or both). That means, if a fuel cost spikes due to high demand (e.g., gas in the “Polar Vortex” winter of 2014) Lennox can switch to the other fuel. Lennox was also recently called on when a Pickering nuclear unit was shut down due to the 2018 Lake Ontario algae situation.
IESO forecasted shortfall It appears likely Lennox will be called on to provide the capacity during the shortfall that the IESO projects during the upcoming nuclear refurbishment years. From a ratepayer perspective, it makes sense.
Carbon tax calculations
Completing the tour and driving home led me to the questions of how much Ontario’s ratepayers might have saved if Lennox had been deemed the back-up for wind and solar power generation or had been used to generate electricity instead of handing out high priced 20-year contracts under the FIT program. The first question would take an inordinate amount of research, so I opted for the latter!
A report (IESO prepared?) titled the Ontario Energy Report has a chart showing emissions generated by the electricity sector and the report for year-end 2017 indicated emissions in Ontario were 14 mt* in 2009 and 3 mt in 2017, for a decline of 11 mt in 9 years. The decline was touted by the Wynne government as attributable to renewable energy in the form of wind and solar.
Looking only at the wind power generation and its associated cost in those nine years provides an indication of just how much Ontario’s ratepayers have paid on a per ton basis to achieve that 11 mt drop! According to the IESO, from 2009 to 2017, wind turbines generated 53.1 TWh (terawatt hours) and since we commenced paying for curtailed power (paid for but not used), ratepayers picked up those costs for about 6.9 TWh.
So, the approximate costs of the grid-accepted wind power generation was about $7.2 billion, and for the curtailed generation was another $800 million. That brings the overall costs of the 11 mt reduction to about $8 billion!
The cost of that reduction of 11 mt looking at IWT (generation and curtailed) only and without solar, works out to $655/ton!
Ontario’s ratepayers have obviously done their bit to reduce emissions and will continue to pay more until the wind turbines and those 20-year FIT contracts finally expire.
We don’t need a carbon tax.
P.S. The second in this two-part series about Lennox will follow shortly, covering off how much we might have saved without wind power
The four-page report says: “Ontario is our nation’s leader in clean wind energy with an installed capacity of 5,076 MW, about 40 per cent of Canada’s total installed wind energy capacity. There are 2,577 wind turbines currently operating in Ontario at 96 separate facilities.” It goes on to say “Supplying 7.7 per cent of Ontario’s electricity demand today, wind energy helps to diversify Ontario’s electricity generation mix.”
What CanWEA’s report doesn’t say is that wind represents over 12% of grid-connected generation and that the 7.7% supply it adds to the grid is intermittent, unreliable and frequently (65% of the time it is actually generating power) out of sync with demand. As an example, on Friday September 14, 2018 at hour 18 (6 PM), when demand in Ontario was near or at its peak, the 4,400 MW of grid-connected wind generated a miserly 10 MWh.
That’s 0.23% of capacity.
To put the 10 MWh in context, that is enough to supply one average household with electricity for a year. At the same time as wind was probably consuming more electricity than the turbines were generating, gas plants (installed to back up wind capacity) were generating 3,862 MWh.
Total generation for hour 18 was 19,274 MWh, not including net imports (imports less exports) of 1,249 MWh, representing Ontario grid demand of 20,523 MWh.* That means the 12% of grid-connected wind generation contributed 0.05% of grid demand. For the full 24 hours of the 14th of September, wind generated just over 3,500 MWh which equates to 3.3% of their capacity. If that isn’t bad enough, 2,500 MWh of that generation occurred from 12 AM to 7 AM when demand is lowest. Needless to say, nuclear, hydro and gas supplied the bulk of Ontario demand for the day.
What this all means is that industrial wind capacity does nothing more than add to the costs of the generation of electricity in Ontario, and, actually, pretty well everywhere else in the world.
Ontario can’t and shouldn’t fall for the hyperbolic self-interested wind spin, so hopefully our politicians recognize it for what it does—drive up the cost of electricity while killing birds and bats and inflicting harm to humans in rural communities due to the audible and inaudible noise emitted.
*IESO’s Daily Market Summary indicates Ontario’s peak demand was 20,845 MWh on September 14, 2018.
