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!

**Unneeded generation costs include: spilled hydro, curtailed wind, steamed-off nuclear and idling gas plants.

What good is wind power?

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”!

*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!

April winds blow in high wind power costs

How badly were ratepayers hit? Millions upon millions for power produced out of phase with demand…

The Independent Electricity System Operator or IESO’s 18 month outlook report uses theirMethodology to Perform Long Term Assessments” to forecast what industrial wind turbines (IWT) are likely to generate as a percentage of their rated capacity.

The Methodology description follows.

“Monthly Wind Capacity Contribution (WCC) values are used to forecast the contribution from wind generators. WCC values in percentage of installed capacity are determined from actual historic median wind generator contribution over the last 10 years at the top 5 contiguous demand hours of the day for each winter and summer season, or shoulder period month. The top 5 contiguous demand hours are determined by the frequency of demand peak occurrences over the last 12 months.”

 The most recent 18-month outlook forecast wind production at an average (capacity 4,000 MW growing to 4,500 MW) over 12 months at 22.2%, which is well under the assumed 29-30 % capacity claimed by wind developers. For the month of April, IESO forecast wind generation at 33.2% of capacity.

April 2017 has now passed; my friend Scott Luft has posted the actual generation and estimated the curtailed generation produced by Ontario’s contracted IWT.   For April, IESO reported grid- and distribution-connected IWT generated almost 703,000 megawatt hours (MWh), or approximately 24% of their generation capacity. Scott also estimated they curtailed 521,000 MWh or 18 % of generation capacity.

So, actual generation could have been 42% of rated capacity as a result of Ontario’s very windy month of April 2017, but Ontario’s demand for power wasn’t sufficient to absorb it! April is typically a “shoulder” month with low demand, but at the same time it is a high generation month for wind turbines.

How badly did Ontario’s ratepayers get hit? In April, they paid the costs to pay wind developers – that doesn’t include the cost of back-up from gas plants or spilled or steamed off emissions-free hydro and nuclear or losses on exported surpluses.

Wind cost=22.9 cents per kWh

For the 703,000 MWh, the cost* of grid accepted generation at $140/MWh was $98.4 million and the cost of the “curtailed” generation at $120/MWh was $62.5 million making the total cost of wind for the month of April $160.9 million.   That translates to a cost per MWh of grid accepted wind of $229.50 or 22.9 cents per kWh.

Despite clear evidence that wind turbines fail to provide competitively priced electricity when it is actually needed, the Premier Wynne-led government continues to allow more capacity to be added instead of killing the Green Energy Act and cancelling contracts that have not commenced installation.

* Most wind contracts are priced at 13.5 cents/kilowatt (kWh) and the contracts include a cost of living (COL) annual increase to a maximum of 20% so the current cost is expected to be in the range of $140/MWh or 14cents/kWh.

Premier Wynne’s Easter basket full of rotten eggs

Count the eggs! $50 million plus, lost in just 3 days!

The nice weather on Easter weekend in Ontario disguised the fact that April 14th, 15th and 16th were really bad days for electricity customers.

Scott Luft’s daily reports detailed the bad news, even before the Independent Electricity System Operator or IESO got out their daily summary for April 12th.   Some of the information in Scott’s reports are estimates, but they have always proven to be on the conservative side. These three reports paint a disturbing picture of what’s going on, and how badly the Ontario government is mismanaging the electricity file.

Here are a few of the events that our Energy Minister Glenn Thibeault and Premier Wynne should find embarrassing. They also confirm what many of us have been telling them for several years.

First, Thursday April 13th saw a disclosure from the Energy Ministry that Ontario paid out $28,095,332 including about $240,000 in interest to Windstream Energy to satisfy the award made to them under the NAFTA (North American Free Trade Agreement) tribunal, due to cancellation of  a 300-MW offshore industrial wind turbine project.

Second, the HOEP (hourly Ontario electricity price) market, traded all of Ontario’s generation over the three days at “0” (zero) or negative value. While total demand for electricity was 1,031,448 MWh over the three days the HOEP market valued it at -$869,220 or an average of -.84 cents/MWh.  The “0” and negative values for the HOEP lasted 77 continuous hours, breaking a prior record of 62 hours.

Wasted, unneeded wind power

Third, during the three days, ratepayers picked up the bill for 99,109 MWh of curtailed wind which exceeded the transmission (TX) and distribution (DX) connected wind by 60.2%. Curtailed wind at an estimated $120/MWh alone cost ratepayers $11.9 million, driving the price of delivered wind (61,882MWh) to a cost of $335.34/MWh or 33.5 cents a kWh.  Total wind costs were $20.8 million.

Fourth, solar power over the three days generated and curtailed (1,124 MWh) 35,539 MWh at a cost of   $16.8 million, which works out to $472.86/MWh or 47.3 cents/kWh.

Fifth was the cost of gas which in three days produced 18,433 MWh, but the cost was $12.5 million and $676.56/MWh or 67.7 cents/kWh.  The 9,943 MW of IESO grid-connected gas operated at 2.6% of actual capacity during the three days.

Sixth was the generosity shown to our neighbours in New York, Michigan and Quebec who took delivery of 157,768 MWh of free power along with a payment of $132,525.

The quick math on the above indicates a cost of wind, solar and gas generation plus the payment for exported power comes to $50.2 million.

Nuclear and hydro was all we needed

That’s bad enough, but if you look at nuclear and hydro generation during those three days, clearly the $50.2 million was “money for nothing” paid for by Ontario’s ratepayers.  Nuclear (including steamed-off of 49,118 MWh) was 688,981 MWh and combined with hydro generation of 324,001 MWh of could have provided 1,012,982 MWh versus Ontario’s demand over those three days of 869,232 MWh leaving 143,750 MWh of surplus.  Three days of nuclear and hydro cost $61.9 million or 6.1 cents/kWh.

Bottom line? Ontario ratepayers picked up the bill for not only the $28.1 million paid to Windstream for a canceled offshore wind project, but also another $50.2 million, making the past four days very expensive for everyone.

The $78.3 million could have been better spent on health care or so many other pressing needs!

It’s time to kill the Green Energy Act and cancel any uncompleted wind and solar contracts before all our weekends turn out like this one!

One spring day just cost you millions

A happy day for power importers south of the border. For you? Not so much…

April 9, 2017 was a perfect day to demonstrate the mess the current Ontario government could have expected if they had simply done a cost-benefit study of the electricity sector prior to imposing the GEA (Green Energy and Green Economy Act).

The April 9th IESO generator report and Daily Market Summary provide highlights of many of the mistakes the Liberal government has made, as does my friend Scott Luft’s “Daily Electricity Supply Estimates.”  IESO’s report fails to provide details of distributor connected (DX) generation (principally solar and wind) whereas Scott estimates those along with the curtailment of wind, solar, hydro and nuclear generation. His estimates have proven to be on the conservative side in the past.

IESO’s “Market Summary” shows Ontario Demand was only 294,600 MWh (megawatt hours) which Scott noted was the “3rd lowest Ontario Demand day in the history of the market” and that day, along with five other recent “lowest Ontario Demand” days have all occurred within the past 12 months.   How low is demand? Scott says the six low demand days were lower than any day during the massive blackout of 2003.


Demand in Ontario on April 9th of 294,600 MWh could have been easily supplied by nuclear generation (236,400 MWh including 14,800 MWh steamed-off) and hydro generation (101,900 MWh including 1,200 MWh spilled, and 2,600 MWh from DX).  Those two clean, emission-free power sources could have delivered 338,300 MWh, leaving 43,700 MWh available for sale to our neighbours.  The 338,300 MWh should have cost Ontario ratepayers $20,554,000 based on what we pay on average for nuclear and hydro generation.  That would equate to 6.1 cents per kilowatt hour (kWh) combined!

As it happened, Sunday April 9 saw 51,400 MWh of net exports (exports less imports) sent to our neighbours in Michigan, New York and elsewhere, along with an average payment of $3.08/MWh. They gladly took those free MWh along with our payment of $158,312.00.

Sunday April 9th also saw Ontario’s ratepayers pick up the bill for transmission (TX) and DX-connected wind of 25,700 MWh and another 46,300 MWh of curtailed (one of the highest curtailed days ever) wind at a total cost of $9.290 million.  If we calculate the cost for just the accepted wind generation (25,700 MWh,) the cost per MWh becomes $361/MWh or 36.1 cents/kWh.

Ontario ratepayers also picked up the bill for the 10,533 MWh of solar generation (DX and TX) and the 667 MWh of solar estimated as curtailed. Solar’s costs were $5.280 million, which means the delivered generation cost last Sunday was $501.28/MWh or 50.1 cents/kWh.

Meanwhile, those same ratepayers picked up a $4.143 million bill for gas generators who delivered 5,773 MWh (TX and DX) at a delivered cost of $717.12/MWh or 71.7 cents/kWh. Scott Luft noted the 5,773 MWh delivered to the system by the gas plants set a record low.*

The cost of unnecessary power for ONE DAY?

The total cost of the unneeded supply of power on April 9th coming from wind, solar, gas and biofuel ($368,000) plus the payment made to export ($158,312.) came to over $20 million.

What that means is, this one day of generation, Ontario’s ratepayers are obliged to pay for, was $40.8 million or 13.6 cents/kWh yet the 294,000 MWh they actually consumed was produced at a cost of $17.9 million (not including the $2.7 million loss on exporting).

Premier Wynne has admitted her government has made mistakes on the energy file. The “mistake” on that Spring day turned out to be a burden on all of Ontario’s ratepayers (rich and poor) with the extra cost of over $20 million in order for the Minister of the Environment and Climate Change and Premier Wynne to be able to claim the “cap and trade” tax is driving down emissions in the energy sector, by reducing generation from fossil fuels (gas).

They are not likely to mention that anyone using electricity from Ontario’s generators would have had to more than double — 13.8 cents/kWh instead of the 6.1 cents/kWh — so they could make that claim!

* Lower gas generation will allow Glen Murray, Minister of the Environment and Climate Change to claim the “cap and trade” tax is working.

Where did our $50 billion go? Or, how Ontario citizens lost $18 mil in just 2 days

Premier Wynne making her announcement: no accounting for costs [Photo: PostMedia]
Almost a week after Premier Wynne announced her plan to reduce our electricity bills by 25%, the wind was blowing!  On March 8, six days after the cost shifting  announcement (from ratepayer to taxpayer), potential power generation from wind was forecast by IESO to produce at levels of 80/95% of their capacity, for many hours of the day.  IESO was concerned about grid stability and as a consequence, curtailed much of the forecasted generation.

When the Premier made her announcement about reducing hydro bills, she also claimed “Decades of under-investment in the electricity system by governments of all stripes resulted in the need to invest more than $50 billion in generation, transmission and distribution assets to ensure the system is clean and reliable.”

It is worth noting that much of that $50 billion was spent acquiring wind and solar generation and its associated spending on transmission, plus gas plants (to back them up because the power is intermittent), and distribution assets to hook them into the grid or embed them with the local distribution companies. It would have been informative if Premier Wynne had had Energy Minister Glen Thibeault provide an accounting of exactly what the $50 billion was spent on.

As it turned out the amount of curtailed wind generated on March 8 was 37,044 megawatt hours (MWh) was just short of the record of 38,018 MWh set almost a year ago on March 16, 2016 (estimated by my friend Scott Luft).  The curtailed wind on March 8, 2017 cost Ontario’s ratepayers $120/MWh or $4,445,280.

The cost on March 16, 2016 was $4,562,160.

What does it mean? Curtailing or restricting power output but paying for it anyway means a portion of the $50 billion spent was simply wasted money. It went to the corporate power developers that rushed to sign those above-market contracts for renewable power.

The other interesting aspect of the surplus power generation on March 16, 2016 and March 8, 2017 is revealed in IESO’s Daily Market Summaries: the hourly Ontario energy price (HOEP)  March 16, 2016 was negative at -$1.25/MWh and on March 8th, 2017 was also negative at -.49 cents/MWh. This meant ratepayers paid for surplus exports sold to our neighbours in New York and Michigan, etc. Net exports (exports minus imports) on March 16, 2016 were 52,368 MWh, and on March 8, 2017 were 37,944 MWh. Total costs of their generation (HOEP + GA) fell to Ontario’s ratepayers along with the cost of any spilled hydro, steamed off nuclear and idling gas plants.

Millions here, millions there = a whole lot of wasted money

So, bear with me here, if we price the cost of the net exports at $110/MWh for those two days, ratepayer costs were approximately $9.8 million with $5.7 million for March 16, 2016 net exports and $4.1 million for March 8, 2017 net exports, not including the $84,000 we paid our neighbours to take our power.

How much did it cost you? Two days out of 729 (2016 was a leap year) cost Ontario ratepayers about $18.1 million for power not delivered (curtailed wind) or needed (net exports).

I hope this helps Minister Thibeault in his calculations for a long overdue accounting to Ontario citizens as to where the other $49.982 billion went.
