Ontario summer day means low power demand, high costs for consumers

A windy, sunny August day: sounds nice? In Ontario, that costs you. [Photo: Dorothea Larsen]
August 5 2017 was an interesting day: the wind was blowing and the sun was shining, in part of Ontario, anyway.

Unfortunately for Ontario ratepayers that weather will cost them a lot of money.

Why? The cost stems from the fact Ontario’s demand for electricity on that day was only 317,000 megawatts (MWh),* according to the IESO Daily Market Summary, probably due to conservation efforts and mild temperatures.  Low demand doesn’t save money: in fact, it will cost Ontario ratepayers millions of dollars due to bad management of the electricity sector by the current government.

I was curious about this windy, sunny day, which led me to contact Scott Luft, a master at using IESO data to give us a real picture of market demand and its costs.  Scott occasionally produces “Daily Ontario Supply Estimates” which provide a picture of both our demand and generated sources, what it cost, how much was exported, how much was curtailed/spilled (wasted), etc., and even how much of the costs were picked up by Class B ratepayers versus Class A.

Scott also estimates curtailed wind, spilled hydro, etc., using a conservative approach; they are generally confirmed months later by IESO.

Scott’s daily estimate for August 5, 2017 confirmed my suspicions!   Emissions-free nuclear and hydro generators alone supplied the 340,000 MWh of power Ontario needed easily, even exceeding Ontario demand by 23,000 MWh.  The cost of that generation was $21.1 million. After allowing for the value of the surplus 23,000 MWh as exports at the average hourly Ontario energy price (HOEP) of $4.94/MWh the cost per MWh comes to $66.34/MWh or 6.6 cents/kWh.**

Double the cost — and you’re paying it

Part of Scott’s daily estimate includes additional costs in the form of all the other generation sources, plus curtailed wind and solar, spilled hydro, biofuel and idling costs of gas plants. When those are added to the $21.1 million of nuclear and hydro, the price billed to ratepayers for the day jumps to $37.8 million — $119.24/MWh or 11.9 cents/kWh.  The Class A to Class B subsidy results in the cost per kWh for the “B” Class (that’s you and me) jumping to $131.10/MWh or 13.1 cents/kWh.

The other generation sources on Scott’s August 5 daily estimates include transmission (TX) and distributor (DX) connected generation, along with curtailed/idled, etc. costs with gas at 9,123 MWh (cost $4.1 million), wind at 49,088 MWh (cost $6.3 million), solar at 13,002 MWh (cost $6.1 million), biofuel at 701 MWh (cost $368,000) and imports of 8,563 MWh (cost $52,000).

The costs to you are mounting

Are you with me so far? What this means is, those other generation sources (including curtailed wind, etc.) of 85,000 MWh cost $16.7 million — $196.47/MWh or 19.5 cents/kWh) and are billed to … you, Ontario’s ratepayers.

Approximately $8.1 million of the day’s costs will be allocated to the Fair Hydro Plan and wind up on future electricity bills. If August 5 was a typical day, the amount kicked down the road for the next four years by the Premier Wynne-led government will amount to $3 billion annually (plus interest).  (The $8.1 million estimate for this day comes from the use of what is referred to as the “Global Adjustment Modifier” set by the OEB at $32.90/MWh from July 1, 2017 to April 30, 2018 and will be reset at the later date. The $8.1 million was obtained by simply multiplying Class B consumption — 246,000 MWh — by the $32.90 “Modifier”.)

Mismanagement of the energy portfolio by the Wynne-led government on August 5 generated a cost for Class B ratepayers that was excessive. It will continue, and lead to an explosion of households living in “energy poverty”*** when the Fair Hydro Plan comes to an end in four years.

The Minister of Energy needs to recognize the problems caused by intermittent and unreliable renewable energy!  Once he understands the latter he should immediately cancel any wind and solar contracted projects that have not commenced construction, along with any in the early planning stages.

Kicking the can down the road via the Fair Hydro Act is anything but fair. Paying twice for non-emitting clean energy simply amplifies the bad management this portfolio has received from our government.

The lower rate is a result of the “Fair Hydro Plan” instituted by the Premier Wynne that kicked 25% of the costs down the road for four years.  The Off-Peak rate back on May 1, 2007 was 3.2 cents/kWh so even after the recent reduction it is still up over 103% in the last 10 years.

*** Energy poverty is generally defined as utilizing 10% or more of a household’s disposal income to pay for their electricity and heating needs.


May power cost stats a harbinger of worse to come

If May is any indication, the Wynne government’s “Fair Hydro” plan costs will be considerable

The “Fair Hydro” plan ushered in by the Wynne government is setting up ratepayers for higher bills as soon as 2021 arrives. When the hiatus ends, limiting increases to ratepayer bills to no more than the “cost of living” (COL) over the next four years, the cumulative debt acquired by OPG to “refinance” the reported $50 billion of electricity assets will have to be repaid.

Early indications suggest the costs will be higher than the $2.5 billion being set aside for the next three years by Premier Wynne and Energy Minister, Glenn Thibeault.

Evidence? A look at May 2017 compared to May 2016 indicates the increase in the Global Adjustment (GA) costs for Class B ratepayers was 7.9% higher than 2016 and well above the May COL index of 1.4%.  Any increase in costs above the inflation rate will be added to the $2.5 billion being refinanced and become the responsibility of ratepayers to pay when the hiatus ends.

Demand drops but the cost goes UP

The IESO May 2017 Monthly Market Report indicates Ontario Class B ratepayers consumed 344,000 megawatt hours (MWh) less than they did in May 2016, which represents a 4% drop. That’s about the same as 460,000 average households would consume for the month. The Global Adjustment (GA) costs on the reduced amount of electricity consumed, however, increased by $82.7 million from $931.2 million in 2016 to $1,013.9 million in 2017.  Many will recall in May 2016, lower consumption during the prior six months caused the OEB to raise rates!

So, what caused the 7.9% spike ($82.7 million) in GA costs?   It appears there were two principal causes with one of them related to Ontario’s “Net Exports”.*

In 2017, net exports averaged 600 MW per hour higher than 2016, meaning they increased by 446,400 MWh (600MWh X 24 hours X 31 days) in May 2017 (enough to power almost 600,000 average households for the month). The buyers in New York, Michigan, Quebec, etc., paid only the Hourly Ontario Electricity Price (HOEP) of $3.17/MWh, while Ontario’s ratepayers were required to pay the GA costs of $54.8 million or $122.89/MWh.

The other major cause of the GA spike appears related to power generation from wind and its record curtailment in May 2017. My friend Scott Luft posts both the generation from TX (transmission connected) and DX (distributor connected) industrial wind turbines (IWT), and also conservatively estimates “curtailment”.  In May 2016 TX and DX connected IWT generated 699,371 MWh, not including 130,000 MWh of curtailed generation.

Combined: wind power in May 2016 cost ratepayers about $113 million or $162/MWh.  May 2017 saw 669,011 MWh of wind power delivered either to the grid (TX) or to local distribution companies (DX). Curtailed wind in May 2017 was a record as Scott estimated almost 524,000 MWh (enough to power almost 700,000 average households for the month) were curtailed.   The cost for generated and curtailed wind increased to slightly more than $158 million for the month, which raised the cost of accepted wind generation to $236/MWh.

$100 million added … for just one month

What this means is, wind-generated and curtailed costs in May 2017 were $45 million higher. Coupled with the increase in net exports of surplus generation and related costs, $100 million was added to the GA … for just one month.  If May 2017 is in any way representative of the four years of the rate freeze (tied to the COL index), the costs of refinancing those assets will be much more than the March 2, 2017 press release suggested it would be:  “These new measures will cost the government up to $2.5 billion over the next three years.”

Based on past forecasts by the Ontario’s Liberal government, keeping the costs at $2.5 billion over the next three years may be a “stretch goal”!

*“Net Exports” are total exports less total imports.


One (megawatt) is the loneliest number

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.

CanWEA wants to “reap” more “benefits” from wind energy

The wind industry association claims wind power is the “least-cost” option. The numbers tell a different story [Photo: IESO]
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.”

Free power is really expensive!

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!

Parker Gallant,

* 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.

Free power for a month for 4,000 Ontario families? Here’s how we missed that

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.

Premier Wynne’s $50-billion elephant

Do a Google search of “premier wynne+elephant in the room” you get 1,140,000 hits while a search for just “premier wynne” only gets 486,000 hits. The word “elephant” has been used by Ontario’s premier on a number of occasions. For example, the “elephant” popped up at one of the expensive Ontario Liberal Party fundraising dinners a year ago where she declared, referring to the provincial deficit, “So while some want to characterize Ontario’s deficit as the elephant in the room, I think a panda is the more appropriate metaphor,” she said. “Truly, Jia Panpan and Jia Yueyue [visiting pandas at the Toronto Zoo] were adorable. But the pandas are leaving Ontario in 2018, and in 2017-18 our deficit will be gone, too.”

The “elephant” has returned for her government in the form of high electricity prices but instead of cute little “pandas,” Premier Wynne was forced to call them her “mistake”!

Let’s look at that elephant now.

The recent release of Ontario Power Generation (OPG) 2016 annual report provides enough information to allow one to figure out exactly what created the elephantine mistake and where to point the finger.   To do that we will compare the results of 2016 to 2009* and show the cause of the above market climb in electricity prices.

Price Comparison

IESO’s (Independent Electricity System Operator) data discloses the cost of electricity generation in 2009 was 6.22 cents/kWh or $62.20 per megawatt hour (MWh) or $62.2 million/TWh (terawatt hour) and in 2016 was 11.32 cents/kWh or $113.20/MWh or $113.2 million/TWh. The increase from 2009 to 2016 represents a jump of 82% in only seven years and in simple terms, is a jump of 11.7% annually.

Using the above prices to show the full cost of electricity generation in those two years is accomplished by multiplying total generation by the cost per TWh so:

Total generation 2009: 148 TWh X $62.2 MM= $9,205 MM

Total generation 2016: 149.5 TWh X $113.2 million = $16,923 MM

(Source: IESO)

That means an increase of $7,718 million (+83.8%) in the raw cost of the commodity-electricity.

Finding the “mistake”

Why did the cost jump 83.8%?

Let’s start with the generation produced by OPG who, according to their 2009 annual report generated 92.5 TWh and 78.2 TWh in 2016. Bruce Nuclear in 2009 generated 35.7 TWh and in 2016 they generated 46.1 TWh.  Collectively OPG plus Bruce generated 128.2 TWh in 2009 and that represented 86.6% of total generation (148 TWh) by all generators that year.  In 2016 the collective total was 124.3 TWh which represented 83.1% of all generation (149.5 TWh) in that year as reported by IESO.

Costing the generation 


For OPG: The costing of generation coming from OPG is a relatively simple task requiring only their gross revenue for the year divided by the generation they reported.  For 2009 gross revenue was $5,640 million for the 92.5 TWh delivered making the all-in cost $61 million/TWh.

For Bruce Nuclear: The reported price paid to Bruce was $65.90/MWH.   So, for the 35.7 TWh they generated, the gross revenue generated was $2,352 million or $65.9 million /TWh.

The combined costs of $5,640 million from OPG plus the $2,352 million from Bruce was $7,992 billion to produce 128.2 TWh making the combined cost per TWh $62.34 million or 6.23 cents/kWh.

As noted above, total costs for all generation reported by IESO for 2009 was $9,205 million meaning $1,213 million ($9,205 million less OPG/Bruce combined of $7,992 million) was spent to acquire the 19.8 TWh generated by the other private generators, making their costs per TWh $61.3 million or 6.13 cents/kWh.  (Note: 9.8 TWh was generated by OPG’s coal plants in 2009.)


For OPG: As noted above OPG in 2016 generated 78.2 TWh and their gross revenue was $5,653 million making their generation cost per TWh $72.3 million (7.23 cents/kWh).  Included in OPG’s gross revenue was a $207 million payment for hydro spillage of 4.7 TWh due to SPG2. (surplus base-load generation).

For Bruce Nuclear: Bruce in 2016 generated 46.1 TWh at a reported cost of $66 million/TWh making so gross revenue was $3,043 million including the cost of steaming off almost 1 TWh due to SBG.  

The combined costs of $5,653 from OPG plus the $3,043 million from Bruce was $8,696 million to produce 124.3 TWh making the combined cost per TWh $70 million or 7.0 cents/kWh.

Cost of the “other” generation

The all-in costs for generation for 2016 was, as noted above, $16,923 million. If one deducts the combined costs of OPG and Bruce Nuclear for their generation in 2016 ($8,696 million) the balance of $8,227 million went to pay for the 25.2 TWh produced by other generators.   Simply dividing the $8,227 million by the 25.2 TWh creates a cost per TWh of $326.5 million or 32.7 cents/kWh. ***

Had the 25.2 TWh cost ratepayers $70 million/TWh, or the same as the OPG/Bruce Nuclear generation combination (25.2 TWh X $70 million = $1,764 million), Ontario ratepayers would not be on the hook for the $6.9 billion in excess costs! ($8,227 million – $1,764 million= $6,932 million or the very high $326.5 million/TWh)

In just one year’s data, compared to 2009, we have located many of the reasons for higher electricity costs. The Premier now claims $50 billion was needed to invest in transmission and generation but her “mistake” was in not seeing the costs would go up more than 83%, principally related to the acquisition of intermittent, unreliable renewable energy from wind and solar!

There may be even more elephants in this particular room.


*The choice of 2009 is related to the Legislative passage of the Green Energy and Green Economy Act (GEA) in the Spring of that year creating the FIT and MicroFIT programs and subsequent acquisition of renewable energy at above market prices.

**Surplus Base-load Generation is simply anticipated “base-load less Ontario demand”.

***The per TWh cost reflects the FIT contracted generation for industrial wind turbines, solar panels, bio-mass along with curtailed wind, conservation spending, the cost of selling our surplus power to other jurisdictions at only 15% of its cost, etc. etc.
