More Global Adjustment: what the costs are

February 21, 2017

The Global Adjustment (GA) charge in 2016 was responsible for 85% of the cost of electricity billed to all of Ontario’s ratepayers, less for large industrial clients.  The cost of the GA is for the cost of generation of electricity at the door (metaphorically) of the generation unit.  It does not include “line losses” which are found in the “delivery” lines of our bills and represented a cost of approximately $400 million at an average 3% line loss!

In dollar terms, IESO reported the 85% cost of the GA was $12.333 billion in 2016.  Because of the size of those GA costs the question on many minds is, what is it?   Steve Aplin of Canadian Energy Issues defines it this way: “It is simply a price recovery mechanism. It is the difference between the price the government promised any particular electricity generating company and the ‘market’ price of electricity.” 

So what are the relative parts of the GA which place the biggest burden on the climb in costs in the “electricity” line we have experienced.

The IESO published a News Release  on January 18, 2017 providing statistics on:  generation by fuel type and its percentage of contribution; ratepayer costs per kilowatt (kWh) for both the GA (9.66 cents per  kWh) and for the HOEP (1.66 cents/kWh) or market price;  and, imports and exports and provincial demand (137 TWh).  IESO don’t provide generation produced within the DX (distributor connected) sector.  The following are best estimates of some of the DX generated electricity and curtailed wind.

Wind

IESO report wind generated 9.3 TWh and Scott Luft reported 1.7 TWh were generated by DX connected wind turbines making total generated generation 11 TWh at a cost of $135 million per TWH (3.5 cents/kWh). An additional 2.2 TWh were curtailed at a cost of $120 million/TWh.

Total cost of wind capacity in 2016

11 TWh @ $135MM/TWh: $1,485 MM

2.2 TWh curtailed wind @$120MM/TWh: $264MM

TOTAL cost wind: $1,749 MM

LESS HOEP value of 11 TWh @$16.6MM/TWh: $183 MM

NET COST of wind to GA $1,566 MM

Solar

IESO reported solar generated .46 TWh in 2016 and the best estimate of DX generated solar at 15% of rated capacity for the 2,100 MW is 2.76 TWh for a total of 3.22 TWh. The average cost of solar generation in the province (roof and ground mounted) is about $480 million per TWh (48 cents/kWh).

Total cost of solar capacity in 2016:

3.22 TWh @480MM/TWh: $1,546MM

LESS HOEP value of 3.22 TWh @$16.6 MM/TWh: $53MM

NET COST of solar to GA: $1,493 MM         

Gas

Due to the intermittent and unreliable nature of wind and solar generation it must be backed up by other reliable generation capable of providing generation when the wind isn’t blowing or the clouds cover the sky. The back-up is generally provided by gas plants.  With 6,800 MW of wind and solar capacity the suggested replacement is 90% of capacity or about 6,120 MW of gas generation representing about 62% of its installed capacity (9,943 MW per IESO).  Gas plants are viewed as “peaking” plant capacity so contracts call for a monthly payment related to the amortized cost per MW and reputedly ranges from $10/15,000 per month per MW.   This calculation will use $10,000 per month/MW!

Total cost of gas generation as back-up for Wind and Solar in 2016

 6,120 MW @ $10,000 per month (6,120 X $10,000 X 12): $ 734 MM

Conservation

Another portion of money included in the GA is conservation spending allocated to all of the LDC based on commitments to reduce their demand over the 2015-2020 period. The total budget over those six years is about $2 billion so equates to $300 million per annum with a significant portion allocated to businesses and upgrades for low-income households.  The LDCs are allowed to apply for rate increases associated with their decline in revenue as a result of the conservation once achieved.

Total cost of conservation spending in 2016

Estimate based on 2015-2020 budget of $2B over 6 years: $ 300 MM

Ontario Electricity Support Program

The Ontario Electricity Support Program (OESP) launched on January 1, 2016 is aimed at low-income households who have suffered from the climb in electricity rates. The OEB study released in late 2014 estimated the cost of the program at $200/$225 million.  Logically, if the province was responsible for driving an estimated 571,000 ratepayers into energy poverty, the program’s cost should have been allocated to the Ontario Ministry of  Community and Social Services, but instead it has become another cost to all Ontario ratepayers.  At this point, the estimate of the first year’s costs are unknown, but if one assumes the OEB’s estimates were close they will impact all ratepayers.

Total cost of the OESP

 Estimate based on OEB’s study: $ 200 MM

GRAND TOTAL COST all of the above: $4,293 MM

Cost per terawatt hour of 14.22 TWh from wind, solar, conservation and OESP added to the GA  $302 million/TWh or 30.2 cents per kWh

 Missing from the above calculation is spilled hydro and nuclear power steamed off at Bruce Nuclear due to surplus base-load generation from wind and solar. The latter would add about another 5 TWh and another $300 million driving the per kWh cost to 32.5 cents per kWh.

If one deducts the 14.22 TWh from total Ontario generation (including DX) in 2016 one is left with 140.1 TWh and if the $4,293 million is deducted from the $12.333 billion of the 2014 GA cost the 140.1 terawatts from nuclear, hydro and gas generation cost was 19% of the GA or                   $57.38 million/TWh or 5.74 cents per kWh

The time has come to kill the Green Energy Act and return to sanity!

No natural gas, more natural gas: what is the Wynne government’s game?

February 6, 2017

In April 2015 Brad Duguid, then Minister of Economic Development, Employment and Infrastructure issued a press release stating: “Increased natural gas access, through the $200 million Natural Gas Access Loan and $30 million Natural Gas Economic Development Grant, will attract new industry, make commercial transportation and agriculture more affordable, help to create jobs, provide more energy choices and will lower electricity prices for businesses and consumers across Ontario.”

The focus was expansion in rural communities and the money offered would do wonderful things including lowering “electricity prices.”  The Duguid statement appears to have flowed from the 2013 Long-Term Energy Plan (LTEP) released by Bob Chiarelli when he held the Energy Minister’s portfolio as noted in the OEB’s 2014-2017 Business Plan.

Just days ago, another press release was issued on the same issue by Bob Chiarelli, Minister of Infrastructure:  “Ontario is expanding access to natural gas for communities that do not currently have service, including those in rural and Northern Ontario and First Nations communities.”  It gave a “Quick Fact”: “Natural gas is the dominant heating source in Ontario and continues to be consistently less expensive than alternative sources such as electricity, heating oil and propane.” The Chiarelli announcement increased the “grant” amount to $100 million.

The recent announcement indicates the Duguid offer fell flat so perhaps Chiarelli’s announcement is an effort to see the claim he endorsed in the 2013 LTEP as one he is determined to follow through on, even if it raises Ontario’s debt by $100 million!

It is also ironic that Chiarelli is pushing expansion of natural gas consumption while our current Energy Minister, Glenn Thibeault is heading in the opposite direction. He recently instructed IESO (Independent Electricity System Operator) to basically shut several of the NUG (non-utility generators) gas plants down. Minister Thibeault’s recent directive to IESO notes:  “Ontario has put in place legislation for its new cap and trade program to limit greenhouse gas pollution while moving to a low-carbon economy.”   Most NUG contracts are gas generation units whose original contracts (executed in the Peterson Liberal government days) are close to expiry, and are “take or pay” contracts.  With the  surplus of power today, Minister Thibeault considers them expendable.  As a result the directive instructed IESO to renew contracts but only: “if the IESO is able to negotiate replacement contracts (IESO Contracts) with OEFC NUGs that incentivize them to operate in a manner that is better aligned with the integrated power system’s needs.”

As noted by Scott Luft some of those NUG contracts have been renegotiated, others ended, (the plants will be closed or mothballed) while some are in the process of  renegotiation.  One of those cancelled contracts offered to produce and sell power for 5.9 cents/kWh, but that offer was rejected even though it was way under prices paid for generation from industrial wind turbines and solar panels. Both those forms of power generation are unable to generate power when needed.

Is the objective of the Energy Minister to reduce emissions from gas plants so Premier Wynne can claim the “cap and trade” tax is working?

Meanwhile, if Minister Chiarelli is successful at handing out the $100 million tax dollars as grants to expand natural gas use, emissions will increase! Any increase will generate additional cap and trade revenue to help pay for the grants and the early shutdown of those gas plants.

Here’s the game: reduce emissions in the (already clean) electricity sector while pushing them up elsewhere and capture additional taxes along the way.

The topsy-turvy world of power policy in Ontario continues.

Amherst Island: perfect example of why wind power can be a bad choice

Ontario’s Energy Minister Glenn Thibeault, at the launch of planning for the next Long-Term Energy Plan, said “We have a robust supply of all forms of energy for at least the next 10 years.”  The month prior to the launch he announced the suspension of LRP II  slated to acquire another 1,000 MW of renewable energy.  His claim at that time was, it would save ratepayers $3.8 billion in electricity costs over the projected term of the contracts.

Cancel the contracts 

Why didn’t he go further and cancel contracts that have not broken ground and saved billions more?   Amherst Island’s “Windlectric” project, owned by Algonquin Power & Utilities Corp., project is just one. On its own, cancellation could save Ontario ratepayers over $500 million in future costs.  Those contracts, signed years ago, either have not been built or are involved in litigation preventing them from breaking ground.   Their sunk costs are small in comparison to their full costs over 20 years and canceling them outright would represent a nominal cost to ratepayers while saving, birds, bats, butterflies and endangered species from harm as well as prevent human health effects, and depreciation to property values.

Cancellation would reduce the amount of surplus energy that is exported at a cost to ratepayers or simply curtailed, but paid for by ratepayers. Savings would be in the billions.

Amherst Island—Owl Capital of North America

 In the July/August 2003 copy of “Wildbird”, Kevin T. Karlson wrote this article “Owl Capital of North America.” and said “An occasional glance at these ‘owls in wonderland’ always brings a smile to my face.” The Owl Woods is the only place where it is possible to see ten species of owls in one day.

Amherst Island, 66 square kilometers in size, is situated west of Kingston along the northeastern shore of Lake Ontario close to the St. Lawrence River and considered a “Hidden Cultural Gem.” The island is the first of the world famous 1,000 islands based on the water flow. The permanent population of about 450 residents swells to over 1,000 during the summer months and attracts visitors from all over the world. People come to see the culture and history of a settlement dating back to the late 1700s by the Empire Loyalists and the Irish immigrants who followed. Many also come to see the birds as the island is on the IBAs (Important Bird Areas) list. Amherst Island is home to “as many as 34 different species at risk known to rely on the Island’s natural environment for survival.” including the threatened Blandings turtle.  

The foregoing paragraph should make the reader wonder exactly why, back in 2011 the Ontario Power Authority (OPA) granted the contract to a shell company (Windlectric) established by Algonquin Power & Utilities Corp. Subsequent to the contract award the Ministry of the Environment (MOE), since relabeled the Ministry of the Environment and Climate Change (MOECC), granted a Renewable Energy Approval (REA) with some modifications to the original contract.  One wonders why the REA was granted as Amherst Island was already designated as an IBA and known as the Owl Capital of North America.  Was it simply because the OPA (now merged with IESO [Independent Electricity System Operator]) gave them a contract, or was the MOECC unconcerned about the heritage of the island and the many species at risk?  

For over 10 years, residents of Amherst Island and their onshore supporters have battled proposals to blanket the Island with industrial wind turbines. The support received by APAI (Association to Protect Amherst Island) has been overwhelming coming from many different groups and individuals, including those who support wind power as renewable energy. Among them are Nature Canada and Ontario Nature who jointly wrote an 18-page letter to the Ministry of Environment and Climate Change in March, 2013. Their logical defence of wildlife had no effect on the outcome of the appeal to the Environmental Review Tribunal.

In fact, the decision of the Tribunal in August of 2015 was a major failure according to Nature Canada: “The Amherst decision is a reminder that we are missing adequate government policy that both promotes renewables in the right places while recognizing and protecting our key biodiversity areas including Canada’s nearly 600 Important Bird and Biodiversity Area (IBAs) such as Amherst Island and the South Shore of Prince Edward County.” 

Organizations as diverse as Heritage Canada The National Trust, Mohawks of the Bay of Quinte, Kingston Field Naturalists, the Dry Stone Wall Association of Ireland, BirdLife International, the Maryland Ornithological Society, the Hawk Migration Association of North America, Pennsylvania Ornithological Society, and Brereton Field Naturalists’ Club all oppose turbines on Amherst Island.

Economic impact

 The Windlectric project proposes 26 wind turbines with a capacity of 74.3 MW and according to the specifications, would be Siemens turbines each with a total height in excess of 500 feet with a hub height of about 330 feet and a blade radius of almost 180 feet. If they generate electricity at the anticipated norm of 30% of capacity, they will produce about 195,000 megawatts (MWh) intermittently and out of synch with Ontario demand. Windlectric will be paid $135 per/MWh plus cost of living benefits up to 20% more, so as much as $162 per/MWh in the latter years of their contract term. At an average of $140 per/MWh, the gross revenue to Windlectric will be $27.3 million annually, or about $550 million over the life of the contract.

Loyalist Township, where Amherst Island is located, was obligated to allow the Windlectric project to proceed because the Green Energy Act in 2009 stripped all municipalties’ local land use planning powers as regards an energy project. The best the township could do was reach agreement on a “Community Benefit Fund” for an annual payment of approximately $520K. Added to that will be realty taxes of around $240K. Ontario limits the assessed value of wind turbines to only $40K per MW. The assessed value of the 26 turbines will be less than $3 million, but their capital cost is over $200 million.

All-in, the township will get about $760K annually — 2.8% of the revenue to Windlectric. Obviously, the contributions Algonquin Power and other large renewable energy companies gave to the Ontario Liberal Party were worth the money.

So, Ontario has a “robust supply” of electricity, wind turbines will harm the 34 endangered species, and we are exporting surplus generation at pennies on the dollar while curtailing wind, spilling hydro and steaming off nuclear energy.   Ontario doesn’t need the intermittent power from the turbines on Amherst Island. We don’t need them in Prince Edward County either (White Pines) (or Dutton-Dunwich, or La Nation, or North Stormont). The Minister should demonstrate that he means what he said recently in North Bay:  “There are some families in this province that are struggling to meet their energy bills. It’s why I’ve recognized and the premier has recognized that we need to do more …That is why we’re making sure we can find ways to reduce bills. Everything is on the table within reason.”

The Minister has an opportunity to save ratepayers $1 billion dollars in future rate increases by simply canceling the Amherst Island Windlectric project and the Prince Edward County White Pines project, to name two.

He should take it.

Surplus power: the other side of wind’s “success story”

Napanee gas plant: more flexible resources needed to offset intermittent wind -- trouble is, they also push emissions up
Napanee gas plant: more flexible resources needed to offset intermittent wind — trouble is, they also push emissions up

January 23, 2017

The Canadian Wind Energy Association (CanWEA) summarized their submission on Ontario’s long-term energy plan (LTEP) to the IESO on their website.  “Ontario is the Canadian leader in clean wind energy with 4,781 megawatts of installed capacity, supplying about 5 per cent of the electricity that Ontarians depend on,” CanWEA said. “Wind has been the largest source of new electricity generation across Canada over the past decade. Over this time, costs have come down as capacity factors have increased.”

Here’s the other side of that apparent success story. It’s not as rosy as CanWEA, the wind power industry lobbyist, would like you to believe.

The IESO just released the 2016 Electricity Data indicating industrial wind turbines (IWT) were responsible for the generation of 9.0 terawatts (TWh) of power, representing 6% of Ontario demand of 137 TWh.

What IESO doesn’t say about wind power generation, however, is annoying.  IWT generation in 2016 was actually10.7 TWh when DX (distributor connected) industrial-scale wind turbines or IWTs are included.  If the 2.2 TWh of “curtailed” wind is added, the bill to ratepayers was for 13 TWh.  The estimate of curtailed and DX wind comes from Scott Luft who does a remarkable job of tracking what is actually happening with generation.  IESO fails to disclose either curtailed or DX generation for whatever reason as they are the settlement agent for all generation in the province.

They have the data available to supply the public with those details.

Surplus baseload means possible grid failure

Not surprisingly IESO continue to run “stakeholder committees” that generate reports disclosing concerns about the intermittent and unreliable nature of wind (and solar), referencing it as “Variable Generation.” They note the production of Surplus Baseload Generation (SBG) which may cause grid failure leading to brownouts or blackouts. One of those reports from May 2016 noted: “SBG in ~65% of hours in 2015, even with 2 major nuclear outages” and “So far, SBG in ~88% of hours in 2016”.

Interestingly enough the current Minister of Energy, Glenn Thibeault on December 16, 2016 issued a directive to IESO instructing them to negotiate an exit from some of the NUG (non-utility generators) gas contracts labeled as “baseload” generators. IESO obeyed the directive as noted by my friend Scott Luft in his recent post “Ontario’s IESO steps off the gas”. We should suspect this action was not aimed at reducing SBG, but instead is aimed as trying to give credibility to the addition of the “cap and trade” tax that took effect January 1, 2017 by showing some negligible reduction in emissions.

The oxymoron in that is also to be found in a June 2016 IESO report titled: “Review of the Operability of the IESO-Controlled Grid to 2020” which suggested:

“We recommend enhancing the flexibility of Ontario supply resources to ensure that there are increased quantities of resources able to address the hour-ahead VG forecast inaccuracy, 95% of the time. This translates to needing ~1,000 MW of additional flexibility. The additional flexibility needs to be located in unconstrained parts of the system to ensure they can operate without restriction. Methods to enhance the flexibility of Ontario resources could include: increased utilization of existing resources, enabling simple cycle operation at combined cycle plants, or adding new peaking generation, grid energy storage or demand response resources. Methods chosen, which are expected to happen through open competitive processes, must ensure that they are cost effective and can meet expected operational duty requirements – given that these resources are required in the near-term to address reliability needs.”

Serious problems with wind

What IESO’s concerns and subsequent recommendations suggest is the variable and unpredictable nature of wind generation has created serious problems in the eyes of those entrusted to run Ontario’s electricity system.

So, here are the facts: power generation from wind cost Ontario’s ratepayers over $1.7 billion (approximately 12% of total generation costs) in 2016 for just over 6% of demand, and will cause ratepayers hydro bills to be further affected negatively.   IESO’s responsibility to manage the system through the exercises suggested in their recommendations will cost the system more money, increasing costs just to ensure industrial wind developments are able to extract money from the pockets of Ontario’s ratepayers.

The government of Ontario led by Premier Wynne will (in the near future) claim their actions on the electricity file were instrumental in reducing emissions, but here’s the thing: the flexible resources IESO seeks will push the emissions up again.

The trick is, that won’t be seen until after the 2018 election.

Outrageous: Ontario’s electricity CO 2 reductions cost

January 16, 2017

Ontario Premier Wynne: not to be outdone  (Lucas Oleniuk/Toronto Star via Getty Images)
Ontario Premier Wynne: not to be outdone

Prime Minister Justin Trudeau announced on October 3, 2016 he would put a price on carbon starting in 2018, if the provinces have not put one in place. He also announced the price would start at $10 a ton and rise to $50 per ton by 2022.  As Ontario residents may already know, as of January 1, 2017 the Premier Wynne-led government already moved in that direction imposing a “cap and trade” tax they claim will burden us with a cost of $13 per month via a tax on gasoline and one on our home heating source of natural gas.

This new tax comes on top of one ratepayers in this province should already be aware of as we have been paying for carbon reduction for some time via our electricity bills.

A website providing the Ontario Energy Report states at the bottom it “was first produced in Q3 2014” and uses IESO as its data source.  The quarterly reports contain lots of information; however, they are generally not available until the end of the quarter following the one being reported on.  The reports provide: generation achieved from the TX (transmission connected) market and details on the capacity of both TX and DX (local distributor connected) sectors.  The report is also specific in terms of both exports of surplus electricity and imports and their respective destinations (exports) or sources (imports).  Contained in the 16 pages are many charts and graphs providing information on other facts such as the average hourly electricity price (HOEP), the Global Adjustment (GA) by ratepayer class (A and B), conservation initiatives, etc.

The report also has a graph specific to CO2 emissions from Ontario’s electricity sector starting in 2007 and identifies, by year, the Megatonne (MT) emissions.   If one looks at 2009, which is the year the Green Energy and Green Economy Act (GEA) was passed, total emissions were 16 MT. In 2015 emissions had dropped to 7 MT.  The 7 MT in 2015 were flat measured against 2014’s emissions and, based on results available for the first three quarters of 2016, it appears set to a level that will be around 5.5 MT!  The drop of 10.5 MT since 2009 suggests the Ontario electricity sector reduced CO2 emissions by 10,5 million tons.

How much have Ontario electricity customers paid?

Ontario ratepayers should suspect the foregoing results have been achieved via our electricity bills as they have climbed at multiples of inflation to accommodate renewable energy in the form of wind, solar, biomass, etc.   So, how much have we have paid, and continue to pay, for that achievement, and what does that translate to on a cost per ton basis?

That question can be answered in part by the Ontario Auditor General (Bonnie Lysyk) report of late 2015. That report noted ratepayers paid $37 billion more than necessary from 2006 to 2014 for contracts negotiated by the Ontario Power Authority, and they will pay another $137 billion more by 2032 to satisfy those and other contract obligations through to their expiries.

That brings the cost to $170 billion.

The AG’s report noted wind and solar contracts were estimated to have been paid $9.2 billion over the actual market value, due to prices that failed to reflect the drop in a competitive environment.

So, using the $170 billion to calculate the cost per ton to reduce the 10.5 million tons of CO2 emissions, it appears ratepayers are paying about $16,000 per ton.   Using only the $9.2 billion (wind and solar) the cost per ton of reducing CO2 emissions comes in at over $835 per ton.  The latter cost does not account for the intermittent and unreliable nature of wind and solar which requires back-up from gas plants and easily doubles the costs, raising the emission reduction cost to over $1,600 per ton.

What the ratepayers of Ontario have been paying to reduce emissions in the electricity sector makes the Prime Minister’s upcoming carbon tax of $10 a ton in 2018 and $50 per ton by 2022 look like chump change!

If he really is intent on driving the Canadian economy into the ground, he needs to take a lesson from Ontario’s Premier Wynne and her predecessor, Premier McGuinty.

Ontario electricity customers paid millions for wind in November

January 14, 2017

strongwindweather

The line of poetry “it’s an ill wind that blows nobody any good” was a reality in November for Ontario ratepayers. The IESO (Independent Electricity System Operator) finally released their November 2016 Monthly Market Report on Friday, January 13, 2017 and there was not much good news in it.

While net exports* were down compared to the same month in 2015, it wasn’t related to the amount of wind power generated and curtailed (estimates of the latter from Scott Luft); that exceeded November 2015 by about 152,000 megawatts (MWh) and clocked in at 1,363,000 MWh.  Generated and curtailed power exceeded Ontario’s net exports in 2015, representing 102.7% versus 72.9% the previous year.  One should suspect November 2016 also saw spilled hydro and steamed off nuclear, but at 102.7% of our net exports, it is obvious that power generation from wind was clearly not needed.

November 2016 was not the month with the highest combination of generated and curtailed wind, but rather the second highest. The highest, according to Scott’s estimates, was December 2016, but we will save that report for another day.

Exported power could have served half of Ontario

Net exports in November 2016 were equivalent to the power that approximately 150,000 “average”** Ontario households would use in a year, or to put it another way, was sufficient to supply 2.4 million of those same households for the whole month of November. That is slightly more than 50% of all Ontario households.

The net exports of 1,326,960 MWh in November 2016 cost Ontario ratepayers $169 million to generate and sold at an average price of $16.69 per/MWh, resulting in income of  $21.4 million.  What that means is, Ontario’s electricity ratepayers subsidized the sale, picking up the difference of $l47.4 million, along with another $30.8 million for the 254,000 MWh of curtailed wind.  Past and present Energy Ministers in the Wynne-led government would probably claim the deeply discounted sale price for those exported MWh was actually a “profit” but most ratepayers recognize that claim to be untrue.

Cancel the contracts

Current Energy Minister Glenn Thibeault has a chance to make his mark by halting all planned acquisition of wind power generation in LRP I and LRP II, as well as cancelling any wind power projects that have not commenced construction, or which have passed their critical “operational” dates.

Time to treat industrial-scale wind power development as that “ill wind”!

*Net Exports are total exports less total imports.

**The Ontario Energy Board claims the “average” Ontario household consumes 9 MWh annually, or 9,000 kilowatts.

 

 

How much is wind power really costing Ontario?

For the cost to provide a small portion of Ontario’s power, wind is no bargain

Not a chance ...
Not a chance …

Most electricity ratepayers in Ontario are aware that contracts awarded to wind power developers following the Green Energy Act gave them 13.5 cents per kilowatt (kWh) for power generation, no matter when that power was delivered. Last year, the Ontario Auditor General’s report noted that renewable contracts (wind and solar) were handed out at above market prices; as a result, Ontario ratepayers overpaid by billions.

The Auditor General’s findings were vigorously disputed by the wind power lobbyist the Canadian Wind Energy Association or CanWEA, and the Energy Minister of the day, Bob Chiarelli.

Here are some cogent facts about wind power. The U.K. president for German energy giant E.ON stated wind power requires 90% backup from gas or coal plants due to its unreliable and intermittent nature.  The average efficiency of onshore wind power generation, accepted by Ontario’s Independent Electricity System Operator (IESO) and other grid operators, is 30% of their rated capacity; the Ontario Society of Professional Engineers (OSPE) supports that claim.  OSPE also note the actual value of a kWh of wind is 3 cents a kWh (fuel costs) as all it does is displace gas generators when it is generating during high demand periods.  On occasion, wind turbines will generate power at levels over 90% and other times at 0% of capacity.  When wind power is generated during low demand hours, the IESO is forced to spill hydro, steam off nuclear or curtail power from the wind turbines, in order to manage the grid.  When wind turbines operate at lower capacity levels during peak demand times, other suppliers such as gas plants are called on for what is needed to meet demand.

Bearing all that in mind, it is worth looking at wind generation’s effect on costs in the first six months of 2016 and ask, are the costs are reflective of the $135/MWh (+ up to 20% COL [cost of living] increases) 20 year contracts IESO, and the Ontario Power Authority awarded?

As of June 30, 2016, Ontario had 3,823 MW grid-connected wind turbines and 515 MW distributor-connected. The Ontario Energy Reports for the 1st two quarters of 2016 indicate that wind turbines contributed 4.6 terawatts (TWh) of power, which represented 5.9% of Ontario’s consumption of 69.3 TWh.

Missing something important

Not mentioned in those reports is the “curtailed” wind. The cost of curtailed wind (estimated at $120 per/MWh) is part of the electricity line on our bills via the Global Adjustment, or GA.  Estimates by energy analyst Scott Luft have curtailed wind in the first six months of 2016 at 1.228 TWh.

So, based on the foregoing, the GA cost of grid-accepted and curtailed IWT generation in the first six months of 2016 was $759.2 million, made up of a cost of $611.8 million for grid-delivered generation (estimated at $133 million per TWh) and $147.4 million for curtailed generation. Those two costs on their own mean the per kWh cost of wind was 16.5 cents/kWh (3.2 cents above the average of 13.3 cents/kWh).  The $759.2 million was 12% of the GA costs ($6.3 billion) for the six months for 5.9% of the power contributed.

But hold on, that’s not all. We know that wind turbines need gas plant backup, so those costs should be included, too. Those costs (due to the peaking abilities of gas plants) currently are approximately $160/MWh (at 20% of capacity utilization) meaning payments to idling plants for the 4.6 TWh backup was about $662 million. That brings the overall cost of the wind power contribution to the GA to about $1.421 billion, for a per kWh rate of 30.9 cents.   If you add in costs of spilled or wasted hydro power to make way for wind (3.4 TWh in the first six months) and steamed off nuclear generation at Bruce Power (unknown and unreported) the cost per/kWh would be higher still.

So when the moneyed corporate wind power lobbyist CanWEA claims that the latest procurement of IWT is priced at 8.59 cents per kWh, they are purposely ignoring the costs of curtailed wind and the costs of gas plant backup.

22% of the costs for 5.9% of the power

 Effectively, for the first six months of 2016 the $1.421 billion in costs to deliver 4.6 TWh of wind-generated power represented 22.5% of the total GA of $6.3 billion but delivered only 5.9% of the power.  Each of the kWh delivered by IWT, at a cost of 30.9 cents/kWh was 2.8 times the average cost set by the OEB and billed to the ratepayer.  As more wind turbines are added to the grid (Ontario signed contracts for more in April 2016),  the costs described here will grow and be billed to Ontario’s consumers.

CanWEA recently claimed “Ontario’s decision to nurture a clean energy economy was a smart investment and additional investments in wind energy will provide an increasingly good news story for the province’s electricity customers.” 

There is plenty of evidence to counter the claim that wind power is “a smart investment.” But it is true that this is a “good news story” — for the wind power developers, that is. They rushed to Ontario to obtain the generous above-market rates handed out at the expense of Ontario’s residents and businesses. And we’re all paying for it.
