Quarterly stats show wind power blowing Ontario electricity costs higher

A power project that began operating in 2017 … wind power causes waste of other, less expensive sources of clean power due to lucrative contracts

A cold, windy winter cost Ontario electricity consumers. And if the first quarter of 2018 is typical, we’ll pay even more…

The IESO (Independent Electricity System Operator) recently released the March Monthly Summary along with the Generator Output by Fuel Type Monthly Report, so that interested parties can see a year-to-year comparison for the first quarter of 2018 versus 2017.

What the “Generator Output” shows for the first three months of 2018 versus the same period in 2017 is, grid-connected generation output was up by over 600,000 MWh (+1.6%). That suggests the colder than normal winter created increased demand, which it did by just over 700,000 MWh.  As it turned out, gas generation increased year over year by about 750,000 MWh, while Hydro generation decreased by almost 200,000 MWh.

Grid-connected industrial-scale wind turbines (IWT) also generated almost 180,000 MWh* more in the first three months of 2018 versus 2017, and saw curtailed (paid for but not used) generation increase by over 50,000 MWh.

Both of those elements increased costs for ratepayers.

In 2017, the approximate cost of wind power generation in the first quarter, coupled with curtailed generation, was just shy of $532 million. In 2018 it was $30 million higher ($562 million). If the first quarter is typical, the cost to Ontario’s ratepayers for the full year could be over $2.2 billion — just for wind power! (Note the foregoing cost estimate does not include spilled water, steamed off nuclear or the high costs of back-up generation in the form of gas plants standing “at the ready” when the wind isn’t blowing.  On the latter issue a 2017 peer reviewed report by Marc Brouillette for the Council for Clean and Reliable Energy showed wind turbines produce power of value to the grid only 35% of the time.)

To reflect on what the IESO report suggests: even though winter months are considered high demand, the grid-accepted wind power presents 65% of the time when it’s not needed. Wind power, in addition to causing waste of other (clean) sources of power such as spilled hydro, steamed off nuclear, etc., results in the IESO selling surplus power to our neighbours at prices well below the cost of wind power production due to their lucrative contracts.  Proof? Look at the grid-accepted wind power versus Ontario’s net exports.   Grid-accepted wind in the first three months of 2017 was 3.46 terawatts (TWh) and net exports (exports less imports) were 2.92 TWh; the comparable period for 2018 saw grid-accepted wind generation of 3.64 TWh and net exports of 2.86 TWh.  In other words, the wind power, if all exported, was done with only partial recovery of its costs and was excess to actual demand.

That raises the question:

Why did Ontario contract for it in the first place and why was it given “first to the grid” rights? And, why don’t we cancel any outstanding contracts** that haven’t been started if what it generates is surplus?

Paying over $500 million per quarter and as much as $2 billion annually for wind power generation increases energy poverty and sends Ontario’s manufacturing jobs south.

*Thanks to Scott Luft for his data on wind generation and curtailment!

** The government awarded five contracts for almost 300 megawatts of new wind power in 2016, one of which has reached Renewable Energy Approval. The contracts will add $1.3B to Ontario’s electricity costs.



Legal action taken on wind turbine noise

It has finally happened!
Using a “private prosecution,” Wind Concerns Ontario has served the Honourable Chris Ballard, Minister of MOECC with a summons for violating the EPA (Environment Protection Act).
The issue is related to the lack of proper follow-up on the thousands of noise complaints filed by individuals throughout the province in locations where industrial wind turbines have been erected.
The complaints date back to 2006 and have continued without any significant attention from the Ministry and have even caused families to abandon their homes in order to seek relief from the noise effects.
Mr Ballard has been Environment Minister since August 2017, and complaints have continued, without resolution.

Dicey math in ECO report on Ontario’s electricity costs

Appalling math supports agenda-laden report from the Environmental Commissioner of Ontario

The 322-page report Making Connections Straight Talk About Electricity in Ontario is mind boggling in its attempt to redefine simple mathematics.

As one example, the Environmental Commissioner of Ontario or “ECO” deals with “energy poverty”: “According to 2015 data, Canada’s National Energy Board found 7% of Ontarians to be energy poor”.

Checking the Ontario Energy Board (OEB) annual Yearbook of Electricity Distributors for 2016, Ontario had 4,612,551 residential customers — so, 7% would represent 322,878 “energy poor” households in the province.

The OEB’s December 22, 2014 report noted: “Using LIM* as a measuring tool, and relying on Statistics Canada household data, Ontario has 713,300 low-income households. The OESP** is estimated to reach 571,000. This estimate recognizes that not all low-income households in the province pay their electricity bills directly (i.e., utilities included in rent).”  Those 713,300 low-income households represented about 15.5% of all households in the province.

So, in one simple sentence, the Commissioner’s reference to energy poverty makes almost 400,000 “energy poor” households simply disappear!

Yet another claim is made in the report where in large bold letters it states: “Ontario sells its surplus power to other jurisdictions for more than it costs to make that power.” Here is the analogy used to explain this claim in the commissioner’s report: if you lend your car to a friend to drive when you are not driving it and he pays you $20 it reduces your annual cost.  The reasoning related to the electricity sector is explained by the ECO:

“The surplus power that we export costs us little or nothing extra on top of the fixed costs, because: Our renewable power has extremely low operating costs; and Our nuclear plants cost virtually the same whether they are making power or not.”

What is deliberately omitted in the report is the unreliability and intermittency of renewable energy; favouritism towards industrial wind turbines is clearly visible in the text. ECO Dianne Saxe has demonstrated support for wind power development and even invested in one that stands at Exhibition Place in Toronto (which seldom generates power).  A plaque at the bottom bears her name.

The “how” we lose money on industrial wind is easily visible to most with a little effort. As an example, IESO rates the ability of wind to be counted on to produce power only 12.9% of the time when it will be needed.  What that means is, while average generation of wind power over one year may amount to 30% of capacity, IESO’s reliance on wind dependable for planning purposes is about one third of its probable annual output.

The foregoing has been borne out by others including a peer reviewed paper titled Ontario’s High-Cost Wind Millstone prepared for the Council for Clean and Reliable Energy. Author Marc Brouillette states: “Two-thirds (65 per cent) of wind generation is surplus to demand and must be wasted or dissipated either through forced curtailment of hydro and nuclear generation or by increased exports to Quebec and the United States, generally at low prices.”

Another recent report I wrote suggests forced curtailment of hydro, nuclear, wind, net exports, conservation and costs of backup for wind and solar generation, i.e., gas plants, were more than $6 billion in 2017 added to our electricity bills.

In other words, the ECO’s claims are not only incorrect, they are an insult to common sense and math literacy.

How much does wind power cost us?

Ontario turbines near Comber: wind is not free

Being asked to do a presentation at Wind Concerns Ontario’s annual conference this past Saturday to describe the costs associated with industrial wind turbines was something I relished!

The presentation I developed used IESO information for 2017.

Discovered in the preparation of my presentation was the fact that nuclear and hydro power alone could have supplied over 100% of all grid-connected consumption for 2017, at a average cost of about 5.9 cents per kilowatt hour.

The cost for Class B ratepayers in 2017 however, was almost double, coming in at 11.55 cents per kwh.

So why the big jump? Have a look at the presentation to see why and look at Slide 6 in particular where you get an inkling of how IESO views the reliability of industrial wind generation in their forward planning process!



Numbers don’t lie: intermittent wind and solar surplus to Ontario’s energy needs

The IESO (Independent Electricity System Operator) released 2017 data for grid-connected* generation and consumption and, surprise! The data reveal that power from wind and solar is surplus to Ontario’s  energy needs.

IESO reported Ontario’s consumption/demand fell 4.9 TWh (terawatt hours) in 2017 to 132.1 TWh. That’s a drop equivalent to 3.6% from the prior year.

Nuclear (90.6 TWh) and hydro (37.7 TWh) power generation was 128.3 TWh, making up 97.1% of Ontario’s total demand (without including dispatched power from either nuclear or hydro). The cost to Ontario ratepayers for the 128.3 TWh was approximately $7.6 billion or 5.9 cents/kWh.

Spilled hydro (paid for by Ontario’s ratepayers but not used) reported by Ontario Power Generation or OPG was 4.5 TWh for the first nine months of 2017. Out that together with 511 nuclear manoeuvres and the number is 959.2 GWh (gigawatt hours) wasted but paid for by Ontario’s ratepayers. Add in three nuclear shutdowns and it means Ontario’s nuclear and hydro generation alone could have easily supplied more than 136 TWh of power or over 103% of demand.

That doesn’t include spilled hydro in the last quarter of 2017 which will probably exceed at least one TWh.

Nuclear and hydro does it all

Nuclear and hydro could also have supplied a large portion of net exports (exports less imports) had all the generation potential actually been delivered to the grid. Net exports totaled 12.5 TWh in 2017.  Grid connected wind (9.2 TWh) and solar (0.5 TWh) in 2017 supplied 9.7 TWh and their back-up generation: from gas plants, supplied 5.9 TWh.  In all, the latter three sources delivered 15.6 TWh or 124.8% of net exports.  Net exports were sold well below the average cost of generation. Exports brought in revenue of about $400 million, but here’s the kicker: that surplus power cost Ontario’s ratepayers $1.4 billion, which is really a loss of $1 billion.

Grid-connected wind, solar and gas generation collectively cost approximately $3.5 billion for the 15.6 TWh they delivered to the grid, included curtailed (paid for but not used) wind power generation of 3.3 TWh. The cost of the wind power was more than $220 million per TWh, or 22 cents/kWh. That’s almost double the Class B average rate of 11.55 cents/kWh cited in IESO’s 2017 year-end results.

The 9.7 TWh generated by wind and solar was unneeded. If it had been required, it could have been replaced by gas power generation at a cost of only around two cents per kWh. Why? Gas generators are guaranteed payment of  about $10K per MW (average) of their capacity per month to be at the ready and if called on to generate power are paid fuel costs plus a small markup.

Price tag: $2 billion

In other words, if no grid-connected wind or solar generation existed in Ontario in 2017 the bill to ratepayers would have been about $2 billion** less! Grid-connected wind generation (including curtailed) cost ratepayers in excess of $1.7 billion and grid-connected solar added another $250 million!

That $2 billion, coincidentally, is about the same cost estimate of the annual amount to be deferred, and paid by future rate increases via the Fair Hydro Plan! In other words the current government could have easily saved future generations the estimated $40 billion plus cost of the Fair Hydro Plan by having never contracted for wind and solar generation!

The IESO results for 2017 sure makes me wonder: why hasn’t the Ontario Ministry of Energy canceled all the wind power projects that have not yet broken ground?


*   Distributor connected solar (2,200 MW) and wind (600 MW) added over $1.4 billion to the GA.

** The first 6 months of the variance account under the Fair Hydro Plan in 2017 was $1,378.4 million.


Ka-ching! Windy days blow away ratepayer dollars

Consumers pay: wind power is surplus, and expensive — emissions-free power is wasted

Wind power on two recent windy days cost Ontario electricity customers three times the current rate … and the surplus meant emissions-free hydro and nuclear was wasted


A simple Google search “wind power is cheapest energy” will generate 1.2 million hits.

If you search “wind power is most expensive energy” you get 2.1 million hits.

Two days last week in Ontario are real-world proof of the cost of wind power, no matter what the government or wind power industry spin tells you. Tuesday, December 5th and Wednesday December 6th were two very windy days, an excellent opportunity to examine both the power generation from industrial wind turbines in Ontario and their delivered cost of power to the grid.

The numbers for those two days:

$$$   IESO forecasts indicated that wind could have delivered 23.8% (177,100 MWh) of total Ontario demand (755,200 MWh) via the 4,200 MW of grid-connected wind capacity.

But wind turbines have a bad habit of generating power when it’s not needed (middle of the night, spring and fall) so the intermittent power must often be curtailed (constrained/wasted but paid for).  It was!

$$$   The IESO curtailed 41.8% of their forecast generation meaning 74,000 MWh were not used!

Via the contracts in place with wind power companies, IESO is obliged to pay for both delivered and curtailed power at prices for grid-accepted power at $135/MWh and $120/MWh for curtailed power.

$$$   Quick math: the cost for grid-accepted wind on those two days meant Ontario ratepayers got charged approximately $22.8 million or $221.14/MWh for grid-accepted wind. That means it cost ratepayers 22.11cents/kWh (kilowatt hour), well above what the average time-of-use rates would be for the average Ontario ratepayer!  The cost of the delivered wind power for those two days was almost three times the current levied* “average” cost of 8.22 cents/kWh, and 3.7 times the off-peak cost of 5.9 cents/kWh.

There’s more (sorry): be assured IESO instructed OPG to spill water over the hydro dams and Bruce Nuclear to steam off nuclear power — so power from our two reliable, emissions-free sources of power generation was also wasted.   OPG and Bruce will be paid for that waste and the cost will be added to our bills.  At the same time gas plants (backing up wind and solar) were being paid for idling.

Those two December days also saw sales of surplus power of 93,700 MWh to our neighbours in New York, Michigan, and others for pennies of the actual cost. In all probability, we recovered around 15% of their generation costs meaning, we bit the bullet for another $10/11 million.

Total: too much

Just the cost of the curtailed and grid-accepted wind and the losses on our surplus exports for those two days was $32/33 million for absolutely no benefit to any of us ratepayers. If every day of the year was like those two days last week, Ontario’s ratepayers would be shelling out over $6 billion annually, due to the abysmal planning and management of the electricity sector by the current Ontario government.

Imagine how far $6 billion would go to improve our health care system.

Wind waste should worry Ontario ratepayers

Ontario’s electricity ratepayers paid more than $500 million in 2017 for nothing

With only one month left in the current year, the bad news on the electricity sector keeps getting worse.

Well before the official sources such as IESO report on how much power industrial wind turbines generated and how much was curtailed (constrained, or paid for but not added to the power grid), my friend Scott Luft has published his estimates for both the former and the latter for the month of November.

As he reports (conservatively), curtailed wind in November was over 422,000 megawatt hours (MWh)  that could have supplied 562,000 average Ontario households with free power for the month.

Instead, no one got free power; the cost of the 422,000 MWh of undelivered wind power to Ontario ratepayers was $120/MWh.  That $50.7-million cost for the month was simply added to the costs of the electricity bills ratepayers will be obliged to pay, while some of it will deferred to the future as part of the Fair Hydro Plan.

Somebody’s enjoying cheap power — not you  

No doubt the wasted wind power presented itself when it wasn’t needed; if it had been accepted into the grid, that extra power could have caused blackouts or brownouts, so it was curtailed.  At the same time, much of the grid-accepted wind was exported to our neighbours in New York, Michigan and elsewhere, at discount prices!  Curtailed wind for November 2017 compared to 2016 was almost 55% higher.

How bad is it? Let’s review the first 11 months of the current year, compared to 2016.

So far in 2017, curtailed wind is about 786,000 MWh higher (+33.8%) at just over 3.1million MWh.  The cost of all the curtailed wind so far in 2017 is approximately $373.6 million, or $94.3 million more than 2016 costs.

And wind wasn’t the only source of power generation constrained. When Ontario Power Group reported their third Quarter (September 30, 2017) results they said this:

“Baseload generation supply surplus in Ontario continued to be prevalent in 2017, resulting in forgone hydroelectric generation for OPG of 1.1 TWh*: and 4.5 TWh in the three and nine month periods ended September 30, 2017, respectively, compared to 0.5 TWh and 3.9 TWh during the corresponding periods in 2016.”  

Translation: ratepayers will pick up the approximately $165 million cost of that waste via their electricity bills.

Not only are we curtailing wind and spilling hydro, but we also steamed off nuclear power generated by Bruce Nuclear at the same time we pay for idling gas plants to back up intermittent wind and solar power generation.

Intermittent wind and solar cost us

The cost of “greening” Ontario with unreliable and intermittent wind and solar keeps climbing, no matter what their proponents or politicians say.  As ratepayers and taxpayers we should reflect on why 25% of the waste of the noted 7.6 TWh of undelivered power and its cost of $539 million (so far this year) is being deferred via the Fair Hydro Plan.  And at the same time, we should recognize that we have experienced the worst possible planning in the Energy Ministry in the history of the province.

The energy sector in Ontario needs real planning by experts that will provide real value for money and save ratepayers from paying more than $500 million a year … for nothing!
