Ontario lost a record $1.8 billion dumping excess electricity in 2020

$1.8 billion dollars: that’s how much Ontarians lost selling electricity to neighbours in 2020 once the revenues earned from the sale are subtracted from the cost of producing the power.

By one accounting, which I’ll show is an Auditor General’s.

It’s been a while since my last post, during which period this blog turned 10. A decade ago, this month, a Premier noted some people think discussing losses on exports is fun, and at the same time lectured, “what you want to do of course is try to manage your system as best as you can so that there's as little extra electricity as possible.” Looking at the longer trend with the benefit of hindsight will be fun (of course), and as an added benefit it will provide a measure of the quality of the system’s managers.

Last month I was contacted by a friend looking to update claims from the 2015 Annual Report of the Office of the Auditor General of Ontario (the Auditor), including:

From 2009 to 2014...Ontario exported 95.1 million MWh of power to other jurisdictions, but the amount it was paid was $3.1 billion less than what it cost to produce that power

From a statistics viewpoint the biggest part of this challenge is figuring out what that $3.1 billion claim was based on. It turns out it’s demonstrated by Figure 10 in that 2015 report - and now we descend into the sordid world of Ontario’s electricity data to determine the origins of the numbers visualized in that graphic. 

I’ve added a tabular table which shows the figures I transcribed from the Auditor’s Figure 10 - not a precise process but one that provides valuable estimates for what is visualized. The difference between the cost of production and revenues in the graphic equal $3.1 billion. Before discussing the “cost of producing Exported Power...as estimated by [Office of the Auditor General of Ontario]” I will note both figure 5 and figure 10 in the 2015 Auditor’s report cite the IESO (Ontario’s hybrid electricity system operator) as the source of revenue from exports: figure 5 prints the figure for 2014 as $636 million while my transposition of the graphics - -done as it’s clearly not that - puts the figure a little below $750 million.

Same source, same measure, same year: two numbers. I’ll revisit this after I discuss a methodology behind the cost of producing exported power that reproduces the results graphed in the Auditor’s Report.

Review of 2017 electricity supply in Ontario

You purchase a  full 9-unit container of energy .

The 3 men who deliver it pour out 2 units out while lecturing on consumption. 
They imply you should make more yourself as they leave.

A couple of months have passed since I last posted to the blog. This may be due to writer's block, or a lack of ambition - or maybe I was wisely waiting until I had something nice to say!

With growing knowledge, and curiosity, I seem to muddle all little issues into the broad themes I deem important - and not only for energy. In this post I'll touch on metrics from 2017 the reader may be looking to this blog to find, with hopes of connecting the data to bigger issues.

There are many possible headlines from an annual analysis:

• electricity "demand", as reported by the system operator was down, to levels not seen in decades
• supply generated from fossil fuels (natural gas) was sharply down too, and again to levels probably not seen in over over half a century
• prices for consumers on regulated price plans were sharply down in 2017 due to legislation and consequent debt (the [un]Fair Power Plan), but,
• total costs for supply declined in 2017, although average unit cost was up slightly (as demand declined more)
• nuclear supply was down as one unit (Darlington 2) was out of service for the entire year due to refurbishment, but the units remaining online largely took up the slack as Bruce Power had record output, as did the set of 9 units at Ontario Power Generation which operated during 2017, and
• for the first year since the system operator reported on their system's wind output, in 2006, it reported a decline (albeit a very slight one)

I didn't wish to dwell on numbers in this post. During 2017 I learned some new data reporting tools which I put on on a site where I invite data-gluttons to learn the filters and views to generate the typical year-end summary statistics, such as the total annual biomass generation for the past decade.
I do wish, in this post, to combine commentary to statistics to demonstrate very good figures from one perspective can have bad implications from a broader perspective. This is particularly important to note as the reasons rates didn't rise sharply in 2017 aren't sustainable.

A benefit of Electricity trade - and what's reducing it

I was wrong.

I've been broadcasting a couple of messages about Ontario's electricity exports: that only the IESO can accurately report on the revenues, and that exports at negative prices are not allowed under market rules. It now seems neither of those is correct. Not only can export revenues be calculated, the analysis of export volumes, and revenues over time reveals benefits of markets, and trade. It's not at all clear Ontario's electricity powers understand the benefits.

I was recently alerted to a claim that the export revenues could be calculated from Intertie Schedule and Realtime Market Price reports. If that sounds confusing it'll gets worse before I'll try to ease off the jargon. As the Intertie Flows reporting is hourly, and the Realtime Market Price reports in 5 minute intervals some data manipulation is required to match the data sets. The IESO has posted annual files (.csv) with values from each of these reports for 2010 through 2016. To dispatch with the technical talk in one confusing swoop, I'll simply note that averaging the "ENGY" rate by delivery hour for each control area in the Realtime Market Price reports, and multiplying that by the "OFFT" value in Intertie Flows report for the same control area does result in the annual figures the IESO has released either to the Office of the Auditor General or in response to Freedom of Information Requests.
I can now extend my work from a previous post to include 2016 data.

Having worked the data down to the hourly time-frame by control area I can additionally summarize revenues, and costs, by jurisdiction. The results have some important messages about trade - as each "control area" has a separate market control price.

I won't discuss imports much in this post because there's nothing new to discuss. Most imports into Ontario are now from Quebec (over 82% since 2012 began), and those are valued in the new analysis almost exactly as the typical Hourly Ontario Energy Price (HOEP) valued them.

Messages about trade from this analysis may be hidden by the realities of communicating summaries of very large data sets. I posted some graphics on hydro(electric) generation by river system, and I received an e-mail from somebody who likely wanted to pursue a story, asking if the data was public knowledge. It was every bit as much public knowledge as what I am writing on today - summarized from hourly data captured from IESO hourly reporting since 2010. However, as most can't process the hourly information, and an official source had not published a summary, it wasn't the basis of a story. I think publication of a summary by an official source is what is required to be considered "public available".

The IESO once summarized volumes and revenues for exports and imports on a web page at www.ieso.ca/imoweb/siteshared/imports_exports.asp (long since a dead link). These monthly totals were meaningfully publicly available as they were both available and summarized by a trusted figure. Remnants of the IESO summaries remains in old government press releases, such as this from May 2012:

"Ontario's electricity market generated over $20 million in April by exporting electricity to other states and provinces, bringing total net export revenues to over $75 million this year.

That figure was, in hindsight, actually net exports ($28.6 million revenue from exporting less $8.1 million importing cost). In 2012 I noted:

[my] figures on export sales are estimates based only on the [Hourly Ontario Energy Price] ... in actuality export customers pay different rates. Because Ontario's market pricing is lower, sometimes much lower, than adjacent jurisdictions, it appears from both the ministry 'news' releases, and National Energy Board reporting, we generally export power about 10% above the HOEP  rates.

10% was the assumption I had when the IESO ceased summary reporting, but with the base data now summarized, I now know that assumption became wrong as they moved up and up, to nearly 70% above HOEP valuations by 2016.

ON electricity pricing 1: retail math and green tales

It's not uncommon to hear a claim made that green energy can't be responsible for the steep increase in Ontario residential electricity rates because it's only around 10% of the total bill. This post could demonstrate calculations using 10%, but it is nearer reality to start with 15% in demonstrating why the argument deceives.

I disputed some claims by Environmental Defence a month ago, but I've used their figures in calculating 15% of the total bill. I did this by simply adding "conservation" in the calculations - while the report I criticized underestimated the cost of solar and (less so) wind, it overestimated the cost of conservation. Together these 3 would have been about 0% of bills a decade ago (2006), and in 2016 they were about 30% of the global adjustment, 28% of all Ontario supply costs (by the ED reports numbers), and since ED has that supply cost as 54% of a residential bill, they claim about 15% of the bill. 

Let's ease into some primitive math using figures we already know. How much does 54% of your bill need to increase for the total to move up 15%?

0.15 divided by 0.54 = .28.

There's the 28% increase in supply cost I noted in ED's figures. There's an assumption, probably incorrect, that supply was always 54% of the bill, but I'll keep things as simple as possible: a 15% increase in the total bill, all other things being equal, required a 28% increase in costs.

As wind, solar and conservation added negligible cost a decade ago, it's worthwhile asking how much spending in these areas increased overall electricity generation cost (ignoring the rest of the bill). It's not 28%:

1 divided by 0.72 (which is 1-.28) = 1.38888....

Costs are increased by 39% when adding new spending that then equals 28% of the new total.

Historical ignorance: on energy losses in decadent Ontario

"marked by decay or decline"

Accusations of losses on electricity exports, and government denial of the fact, is far from news, but the reappearance of the topic in Ontario's legislature demands it be reviewed anew.

Progressive Conservative Leader Patrick Brown says the province sold $9.4 million worth of excess electricity for just $144,000 on Nov. 10...
Brown says Ontario has "given away" $6 billion in surplus electricity since 2009 by selling it at a big loss...
Energy Minister Glenn Thibeault...says Ontario made $230 million in 2015 by selling excess electricity to neighbouring jurisdictions.
Thibeault says Ontario suffered through power shortages and brown outs when the Conservatives were last in power, and had to spend up to $500 million a year to buy electricity from its neighbours to keep the lights on.
   -the Canadian Press via ctvnews.ca

I wrote on the costs to Ontario ratepayers of cheap exports almost 6 years ago, in rebutting the same spin as the Minister delivered yesterday when presented by a previous Premier. Later, in 2013's Ways to estimate Ontario's losses on electricity exports I demonstrated multiple methods to quantify losses on exports. The estimates of losses vary by methodology and assumptions, but if methods are applied consistently all indicate increased costs to Ontario consumers from producing far more electricity than necessary to meet their demands .

I won't revisit all the arguments I've made in the past, but instead tailor a response to the rookie Minister's old denials, emphasizing how poorly he is prepared to undertake the task of developing a plan for the sector.

The growing subsidy of wind and solar in Ontario

I was recently asked the amount of subsidies paid to wind and solar generators in Ontario, and felt answering deserved a blog post. I will show that from the introduction to Ontario's transmission grid of the first industrial wind turbines in 2006 up to June 30, 2016, subsidies to wind and solar generators have been approximately $6.4 billion.
More important than the figure, are the trends in annual magnitude and composition.

I have tried not to use the word "subsidy" in recent years - having been guilty of using poorly in the past. However, it's increasingly clear to me that avoiding the "subsidy" discussion has been harmful to Ontario's ratepayers.

In Ontario the word "subsidy" is often quantified by the amount paid for electricity by consumers above the price of that electricity in Ontario's market. The method of recovering that amount is the global adjustment mechanism. The complicated system with huge figures (on track to hit $12 billion in 2016) meant great attention was paid when the Auditor General of Ontario reported, "[from] 2006 to 2014, electricity consumers have already paid a total of $37 billion, and they are expected to pay another $133 billion in Global Adjustment fees from 2015 to 2032." 



However, with all generators in Ontario now recovering some of their costs outside of the market rate, the global adjustment has become a poor tool for defining subsidy. Treating the global adjustment as a subsidy ignores that Ontario's weak electricity market isn't intended to recover all the costs of generation. When the market functions to provide any indication of generator cost, it is usually only the fuel portion of a natural gas-fired generator's expenses. This makes the global adjustment a poor definition of a subsidy - although it's a fine indicator of the poor quality of Ontario's electricity market.

2015 Ontario Electricity Data Summary Part 2: component costs, and cost shifting

this post follows 2015 Ontario Electricity Data Summary Part 1: the basics

The electricity sector data widely communicated by the system's operator (the IESO) is increasingly inadequate for analysis of cost and demand trends in the province. This post needs to utilize more obscure data, and the creation of some data through estimates, in order to demonstrate the causes of overall higher prices and the shifting of costs to the smallest consumers of electricity. 2015 continues a trend of rising overall electricity costs, and the increases are amplified by 50% for small consumers.

Consumers can be broadly grouped into three groups: exporters, Class A and Class B. In 2015 a new website appeared that does provide a quarterly report indicating the much different pricing for Class A consumers ("large electricity consumers"), and all other domestic consumers - Class B.
Up to the end of the September the total pricing for the classes was quite different: Class A had averaged $6.24 cents per kilowatt-hour ($62.40/MWh), which was 37% lower than Class B's 9.89 cent/kWh average.

To understand the cost drivers it's useful to first examine the difference between the forms of generation the IESO considers "Ontario Demand", and the metered consumption of Ontario consumers.

The IESO provides, upon requests, figures for "consumption" by the consumer classes defined by the global adjustment mechanism/s. With these figures, and the breakdown of the global adjustment totals by class A and class B published by the IESO, it is possible to recreate the reported average commodity rates. The widely cited "Ontario Demand" refers to demand for supply from transmission connected (Tx) generators. Other generators are connected within distribution grids (Dx). Consumption figures for December won't be available until after the global adjustment totals are finalized in mid-January, but we have enough data to estimate 2015 and demonstrate that over the past 5 years "consumption" in Ontario has gone from being less than "Ontario Demand" to exceeding it.

The change in the the difference between Tx generation ("Ontario Demand") and consumption means that generation is increasing within distribution (Dx) networks. It should be expected that Dx generation data be reported along with Tx data to properly communicate component supply costs.

November Stats: Global Adjustment climbs to two-thirds of charge

The IESO's second estimates for November put the global adjustment rate at $55.68/MWh for November, which is more than double the weighted average HOEP rate of approximately $26.52.

November saw new rates for customers under the OEBs Regulated Pricing Plans (RPP) that should average $79.32/MWh, so November's charges, if not adjusted downwards, would reverse the summer's trend where customers with RPP rates paid more than customers without them - business exposed the the commodity charge (HOEP + GA) will see rates rise almost 14% from November 2011.

One month ago I wrote that the IESO's month-end global adjustment estimate looked low:

They'll need to revise upward their estimate of $542 million by close to 10% if the final ends close to my estimate of  $585 million.

They did not.  The October final was not changed significantly - but now November's $588.2 million estimate exceeds my $531 million estimate by a similar amount.  It looks to me like they've moves the costs forward.  The 12-month total for the global adjustment is now over $6.5 billion dollars as it increases at a quicker pace than anticipated by Ontario's Auditor General in his 2011 Annual Report (pg 94)

Week 26 Reporting: Nuclear productivity highs and continued pricing woes

I've had a lull in posting as I am developing some more reporting on my data site to support future blog posts.
Here's a post to indicate how my Weekly reporting demonstrates the supply mix, pricing, and export issues frequently noted on this blog - and increasingly elsewhere.

Weeks 25 and 26 are amongst the highest demand weeks of the year.  Peaks are far higher than in January, but total weekly consumption is yet to surpass week 3.

Summer is now our peak (hourly) demand period, which should raise some supply requirement issues.  During the highest demand week in January, peak demand was ~7000MW above the minimum demand for the week.  During the heat of week 25, demand rose to ~12000MW above the minimum demand for the week (essentially doubling the week's minimum demand).

Monthly Ontario Electricity Export Figures

Every month Ontario's Ministry of Energy puts out an offensively dishonest misinterpretation of our electricity export profit/loss ledger.
It is here for April now:

Electricity Exports Continue to Generate Revenue:

"Ontario's electricity market generated over $20 million in April by exporting electricity to other states and provinces, bringing total net export revenues to over $75 million this year.
This revenue helps Ontario:

• Keep costs down for families
• Build and maintain a clean, reliable and modern electricity system"

Here's a shorthand way to calculate how this absolutely does not "keep costs down for families."

Electricity Exports Benefit Generators - not families

As the government loses control of electricity pricing, the Ministry of Energy continues to put out a monthly press release on exports that would make Baghdad Bob blush.

2012: 2nd highest year for volume, lowest revenue in 5 years

A Sober look at Ontario’s 2011 Electricity Figures

"He uses statistics as a drunken man uses lamp-posts...for support rather than illumination."
                                    -Andrew Lang (1844-1912) Scottish poet, novelist and literary critic

Ontario’s Independent Electricity System Operator (IESO) issued a news release on January 6th titled,“Composition of Ontario’s Electricity Supply Mix Continues to Change: Consumer Response Supports Reliability.” The introduction posits there were three trends highlighted in the data; “increasing production from renewable resources, reduced dependence on coal-fired units, and a more active role for consumers in managing their consumption.”   Not exactly the 3 trends I'd look for

• The 'customers' most active in curtailing peak demand are businesses, as Parker Gallant and I demonstrated in a recent article. Many of them pitch in by closing up altogether;
• Use of coal-fired generation is reduced because the periods we need it are down, but at peak demand we relied on coal-fired generation (I wrote on that here);
• There is no trend to increasing production from renewables in the IESO data.

There is a brief uptick. From only the data presented by the IESO, summing up hydro and wind the numbers go from 39.7 TWh in 2008 to 40.4TWh in 2009, 33.5TWh in 2010, and then we have a singular point as an uptick in 2011, to 37.2TWh. While up on a dry 2010, the total renewables figure is unimpressive against a longer trend. In the past 22 years, renewables have infrequently produced less output than in 2011.

Accounting And Ontario's Electricity System: A Farce

People are trying to make sense of the record low electricity price Ontario achieved this Sunday.  I wrote about it Monday morning, but most are getting their information from other sources, including the Toronto Star– and these source don’t seem to working with any foundation in accounting.  I have some experience with ‘retail math’ – which is probably about a grade 7 level of math. I combined unease with my qualifications, my interest in technology and theories of education, and my occasional feeling I should take a more active interest in my children’s schooling, and brushed-up on my accounting with some lessons at the Khan Academy (which I learned of in a recent column by Margaret Wente). 

Response to Comments on Power Dumping

It was an honour to work with Parker Gallant on “Ontario's Power Trip: Power dumping.”  I wanted to follow-up on some of the comments now attached to the article.  I don't do this necessarily as a response to the commentators, but some of the arguments recur frequently in government and ENGO releases, so I have worked on some responses.

Ontario’s Power Trip: Power dumping

The article,by Parker Gallant and myself, first appeared in the Financial Post

During the spring months in Ontario, the winds blow a lot. For companies in the wind-power business, that’s good news. For the province’s electricity consumers, though, it’s another financial disaster that, on an annual basis, drains up to $400-million out of consumers’ pockets. But that money doesn’t directly fund green electricity for Ontarians who pay for it. Instead, the bulk of wind power is essentially surplus power that is exported to the United States and out of province at rock-bottom prices. Ontarians are paying $135 for units of power that are dumped on the export market at prices as low as $20. Sometimes, Ontario has to pay other jurisdictions to take the surplus off its hands.

This past May, Ontario’s wind producers generated 284,000 megawatt hours (MWh) of electricity. For each MWh, the producers collected $135, for a total of $38-million. That money is paid out of the churning slush fund that is now the Ontario electric power system. The system, through its byzantine structures, sold that same power into the electricity market at market prices. The average market price for electricity in May was about $25 a MWh. Wind power, however, rarely gets even the average price.

Because wind often blows when power is not needed, and the Ontario government has mandated wind, the Ontario power system is stuck with surplus power that has to be unloaded, at whatever the market will bear, which is usually below average market prices.

Smile, And Say "Goebbels" - A note from the government

This release, Electricity Exports Help Keep Ontario's Supply Strong,  is remarkably dishonest


"This revenue helps Ontario:

• Keep costs down for families"

No, this revenue set against the costs of producing the power does not keep costs down for families.  This figure is meaningless by itself, and put together with the purchasing costs adds, by my calculations, $50 million to the costs of Ontario's consumers in the month of May only.  Net Exports (exports less imports) of over 1,300,000 MWh sold for only $3,100,000.

Mayday, Mayday! Global Adjustment Still Soaring to Monthly Records

The operator of Ontario's electricity system, the IESO has posted it's 2^nd estimate of the global adjustment for May 2011, and the estimated rate of $49.94/MWh is a record high, as is the $496.1 million dollars. I've been on the themes driving the increased pricing in Ontario for some time, and May serves as the starkest reminder of the remarkable callousness of Ontario's electricity policy in disregarding Ontario's residents, and it's businesses.

Jobs Lost, And Ontario's Cheap Electricity Exports

Ontario has been providing Quebec with cheap electricity following the loss of large industrial customers in Ontario to the cheaper electricity of Quebec.

10 for 10: Ontario's Surplus Baseload Generation

The latest SBG report shows there are only 10 hours during the next 10 days when Ontario is capable of not producing too much supply for Ontario's market.

Over the first 130 days of the year, Ontario's net exports grew 50% from last year, while the market price (HOEP) dropped 8%.  The variance between the price Ontarians pay, and exports, is the global adjustment.

In 2011 this means export customers have paid approximately $143.8 million dollars less than Ontarians would have paid for the same amount of electricity (3,745,460MWh of net exports at $38.39/MWh).

Ontario's Reduced Coal-Fired Generation Explained

The Ontario government recently announced, “Ontario's use of coal-fired power is down 90 per cent in the first three months of 2011, when compared to the same time frame in 2003."  This is good news, which is followed by some questionable claims regarding health impacts, and then the misleading statement that “Ontario is on the right track to building a clean, modern and reliable electricity system using renewable sources of power - like wind and solar.”   Wind and solar don't have much to do with the reduction of coal-fired generation.
