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 If it had been required, it could have been replaced by gas power generation at a cost of only around two cents per kWh.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.

How much did Premier Wynne’s hydro “mistake” actually cost?

Five months ago, Premier Kathleen Wynne admitted to the delegates at the annual Ontario Liberal Party convention her government “made a mistake” allowing electricity rates to rise so high.  Those rates have actually soared, increasing by 80.9% from 2009.

Comparing Ontario electricity rates to other indicators such as inflation, shows just how bad the situation is. Comparing the IESO (Independent Electricity System Operator) Monthly Summaries for January and February 2009 with the same two months in 2017, the combined costs of HOEP (hourly Ontario energy price) plus the Global Adjustment (GA) show costs per kilowatt hour (kWh) have increased from 5.85 cents/kWh to 10.58 cents/kWh. That is an 80.9% increase.  Average inflation over the same time-frame has increased about 14%.   (The reader should note the 2009 and 2017 costs are before HST so the 8% reduction commenced January 1st has had no effect on contracted or regulated electricity rates.)

So how bad? The cost of the basic commodity has increased by almost six times the inflation rate!

Commodity cost is way up

Reviewing the IESO Monthly Summaries for the two-month periods in 2009 versus 2017 also shows Ontario demand fell by 7% or 1,713,000 MWh (1.7 TWh). The Summary reports indicate the 24.43 TWh representing Ontario demand in 2009 cost $58.49 million/TWh or $1,429 million for January and February. The 22.7 TWh of Ontario demand in 2017 cost $105.78 million/ TWh or $2,330 million for the same two months.  That represents an increase in the commodity cost of electricity of $901 million for 7% less electricity — an average monthly increase of $450 million.

So, why?

Exports

One of the reasons was the drop in the market price as the HOEP fell from an average of $51.93/MWh in 2009 for the two months to $21.56/MWh in 2017 while the GA jumped from an average of $6.56/MWh in 2009 to $82.27/MWH in 2017. What that means is, the loss on exports from Ontario in 2009 cost Ontario ratepayers $13.1 million and in 2017 cost ratepayers $174.2 million as the GA costs are not included in the sale of exports via the HOEP.

OK, of that $900+ million increase, we have $174 million found … $727 million to go!

Wind power

Another obvious cause of the big jump was generation and payment for curtailment of power from industrial wind turbines (IWT). Back in the early part of 2009, Ontario had approximately 800 MW of IWT capacity; in the early 2017 we have about 4,550 MW of capacity.   According to my friend Scott Luft, who uses IESO data to estimate the generation and curtailment of IWTs,  in 2009 the turbines delivered almost 395,000 MWh in January and February. In 2017, it’s a different story: generation and curtailment combined jumped to about 2,926,000 MWh.

The contracted wind power prior the passage of the Green Energy Act is estimated to be at the rate of $90/MWh, whereas wind power contracted for after the Act was at $135/MWh (plus a cost-of-living annual increase) meaning they currently are estimated at $140/MWh. The math on the 2009 generation therefore shows a cost of $35.5 million and the 2017 generation/curtailment cost becomes $409.6 million.  The increased cost of wind from 2009 is ($409.6 million less $35.5 million) $374 million.   Deducting the $374 million from $727 million leaves $353 million to find to get to $901 million!

Gas

Since 2009, more than 3,300 MW of gas plant capacity has been added to the Ontario grid. Its addition was basically to back up the wind and solar capacity (which is unreliable and intermittent) to ensure sufficient generation is available during renewables’ failure and high demand periods.  The private sector companies investing in those plants are paid for their capital investments amortized over their life span. When generating electricity they receive fuel costs plus a nominal markup. Payments details are not available in the public domain, but it is understood payments contracted are per MW of capacity, and  estimates given are $8/15,000 per MW per month.  Assuming the 3,300 MW of capacity secured since 2009 is at the mid-range ($12,000 per MW) the cost to ratepayers is $79 million (3,300 X $12,000 X 2 months).

That $79 million means we are still looking for $274 million.

Consuming less but paying more

IESO shows ratepayers consumed 1.7 TWh less in the first two months of 2017 than in 2009, but paid more. That is evident in OPG reports.  As OPG has not released its 2017 1st Quarter report estimates are based on the 2016, 1st Quarter report.  First we estimate spilled (wasted) hydro was 1.2 TWh at a reported cost of $44 million/TWh so that cost ratepayers $53 million.   The 21.0 TWh produced by OPG in the 2016, 1st Quarter generated average revenue per TWh of $70.4 million.  Estimating the first two months of 2017 generation at 14 TWh results in a cost of $985.6 million.  In 2009 OPG generated 25.6 TWh at an average of $57.8 million/TWh. Again estimating the total cost of the 17 TWh generated by OPG in the first two months produces a cost of $982.6 million so adding the $3 million to the spilled water cost shows an increase of $56 million.  Subtracting $56 million from $274 million means we are looking for the last $218 of the increase.

Solar, conservation, bio-mass and sundry

We assume the balance of the increased 2017 versus 2009 costs came from solar and bio-mass with a portion from the conservation program. Based on Figure 23 “Total Global Adjustment by Components” of the IESO Summary report we can estimate the costs of each of those for the two months.  It appears conservation spending (absent in 2009) represented about $50/55 million for the first two months of 2017 and bio-mass (incented by the FIT and MicroFIT programs) generated costs of around $40 million.  Solar (low during winter months) generated a minimum of $100/$120 million in costs for the two months based on the IESO Figure 23.  While those are “best” estimates to get to the increase of $901 million for the two months, we have not included increased costs from the IESO and OEB budgets which have both increased.

“No checks” in the system

An article recently appeared in the Globe and Mail written by George Vegh, former general counsel to the OEB.  This paragraph is perhaps why Premier Wynne admitted to her “mistake”

“Generation procurements are determined entirely by the government. The system operator – the Independent Electricity System Operator (IESO) – implements government directives. Neither the Ontario Energy Board nor any other independent regulator reviews these procurements. There are no independent criteria, no cost-benefit analysis, no consideration of the need for the procurements, and no review of alternatives. In short, there is virtually no check on the power to procure supply.”

 

What we have in Ontario is a “mistake” that will continue to cost Ontario ratepayers and taxpayers billions for years to come.

Admitting a mistake is one thing, doing something about it is another: Premier Wynne needs to recognize the Ontario Liberal government’s error, kill the Green Energy Act, and halt continued procurement of power from unreliable and intermittent wind and solar generators!

Premier Wynne’s $50-billion elephant

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

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

Let’s look at that elephant now.

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

Price Comparison

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

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

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

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

(Source: IESO)

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

Finding the “mistake”

Why did the cost jump 83.8%?

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

Costing the generation 

2009

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

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

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

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

2016

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

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

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

Cost of the “other” generation

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

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

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

There may be even more elephants in this particular room.

 

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

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

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

Ontario Power Generation report: good news and bad news

Ontario Power Generation (OPG) just released its annual report for the year ended December 31, 2016.

It’s a mix of good and bad news.

For example, gross revenue (net of fuel expenses) increased by $137 million and $34 million of that increase found its way to the bottom line, for a $436 million profit.

Generation from 2015 increased slightly from 78 terawatt hours (TWh) to 78.2 TWh, with nuclear generation increasing by 1.1 TWh and hydro decreasing by .9 TWh, which was further exacerbated (see next paragraph) by spillage due to surplus base-load conditions.

The bad news was that 4.7 TWh of hydro was “spilled” or wasted in 2016, up from 3.7 TWh in 2015. Those wasted 4.7 TWh of power could have supplied more than 500,000 (approximately 11% of all residential ratepayers) average Ontario homes with electricity for the full year.

The spillage by OPG didn’t affect their revenue, however, as they are paid for spillage at an average of about $44/MWh or $44 million/TWh. That means they received $207 million for wasted power and paid the Ontario Ministry of Finance the “water rental” fee for the spillage (although the latter wasn’t disclosed in the report).

Other “good/bad” news indicates OPG sold their Head Office on University Avenue in Toronto with closing scheduled for the second quarter of 2017. They expect the sale will generate an after-tax profit of $200 million.  The bad news is, OPG is obligated to turn over the profit to the Consolidated Revenue Fund. The land, building and maintenance costs fell to the ratepayers of Ontario to pay for via the electricity rates, yet the profit generated on its sale will be tossed into the bottomless pit of the Finance Ministry, instead of going towards reducing OPG’s costs of generation which could have benefited ratepayers.  That $200 million won’t even pay the interest on Ontario’s debt for a week!

SOLD! But the money won’t help you ..

The previous Energy Minister Bob Chiarelli on June 9, 2016 (four days before he was replaced by Glenn Thibeault) also issued a “declaration” to OPG instructing them: “to transfer, sell, dispose of or divest all of the Corporation’s interest in the Lakeview Site, comprised of the Municipal Park Lands and the Uplands”.  The Lakeview site is 67 acres running along the Lake Ontario shoreline and the Municipal Park Lands are the remaining 110 acres of the Lakeview Site.  Any excess revenues associated with the sale is to be transferred to the Government (Consolidated Revenue Fund), again rather than going to reduce electricity rates.

Ontario’s ratepayers absorbed the impairment costs of closing the coal plants in 2003, absorbing a “loss of $576 million as a result of the termination of cash flows from these stations after 2007.” The ratepayers of the province deserve to benefit from any recovery resulting from the write-off of the plant closings!

All this is more evidence of the “shell game” being perpetrated on Ontario ratepayers and taxpayers and the continuing legacy of the McGuinty/Wynne-led governments.

More to come …
