Updated Weekly Reporting:Wk 7

The data sheets behind the NEW: Weekly Report, have been refreshed, so the reporting is now showing for the week of February 15-21.
The demand trend down continued, with the average Ontario Demand dropping 542MW against the same week the previous year.
The price trend down continues, with the average Hourly Ontario Energy Price dropping over $8/MWh from week 7 the previous year, which is about a 25% drop.  The range in the HOEP over the week was mainly limited, with a low of $14.86/MWh but the high came in one exceptional hour on Saturday the 18th as prices surged to $280.73/MWh at 7pm, as demand peaked, and as wind output dropped.  During the week the average pricing for off-peak hours, which include all of Saturday, exceeded the average price for on-peak hours.
The depressed prices did coincide with a slight rise in net exports.

Updated Weekly Reporting:Wk 6

The data sheets behind the NEW: Weekly Report, have been refreshed, so the reporting is now showing for the week of February 8-14.
The demand trend down continued, with the average Ontario Demand dropping 615MW against the same week the previous year, but a cold weekend did provide the first days up over the comparable day a year earlier (ie. the 6th Saturday of the year).
The price trend down continues, with the average Hourly Ontario Energy Price dropping over $11/MWh from week 6 the previous year, to only $22.48.  The range in the HOEP over the week was extremely limited, with a low of $14.51/MWh and a high of only $28.34.
The depressed prices coincided with an increase in net exports to an average of 1452MW per hour.

Nuclear output was again the most reduced source, compared to the 6th week of 2011, while coal saw the largest increase.

Drummond Report - On Electricity, it's worthless

Officially titled, the Don Drummond led "Commission on the Reform of Ontario's Public Services" devotes a section to electricity.  Here's the recommendation - along with my initial reaction to each of them:

Recommendation 12-10: Eliminate the Ontario Clean Energy Benefit as quickly as possible.
I guess that would be now – the vote buying worked already

Recommendation 12-11: Review all other energy subsidy programs against measures of value for money and achievement of specific policy goals.
Bureaucrat paid to control expenses recommends more reviewing; empty-headed twaddle.

Updated Weekly Report: Wk 5 now showing

The data sheets behind the NEW: Weekly Report, have been refreshed, so the reporting is now showing for the week of February 1-7.
The demand trend down continues (as does the milder than usual winter), with the average Ontario Demand dropping over 1400MW against the same week the previous year.
The price trend down continues, with the average Hourly Ontario Energy Price dropping over $14/MWh, to only $21.58.
There was a large curtailment of supply necessary the morning of the 1st, coincident with strong wind production and negative prices.

Weekly Reporting on Ontario's Electricity System

After early reports, my testing does indicate the page referenced in this post, and many pages already on this site, are not compatible with Internet Explorer 8 - the last IE available for Windows XP.

I have no intention of making the pages compatible - see the sidebar for options.

I've posted a summary of weekly supply and demand statistics in Ontario. The final pieces of the data driving the reporting are posted by the Independent Electricity System Operator (IESO), which is generally on Friday. My reporting thus far agrees, as expected, with the reliable IESO reporting .  There are 3 reasons to check out mine:

• Context - I include comparison data to the same week in the prior year. 
• Graphics - Primary the communication is via graphs.  
• Curtailment - The reporting includes an estimation of how much supply is curtailed, hourly, throughout the weekly period.  The IESO does not.
• Supply Mix information.

The weekly reporting can be accessed by selecting the "NEW: Weekly Report" tab, beside the "Home" tab on this site. 

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.

My Pledge Suggestions

I subscribed to a e-mail from the Ontario Power Authority, which sent out some power saving tips for the 'festive season.'  As the owner of an old home (1907), here's a review of the their 'tips for the festive season"

• Replace old, incandescent holiday lights with LED lights. LEDs run much cooler, have lasting power and are energy efficient.
Depending on how many 10's of thousand of $s you have spent on upgrading your building envelope, be careful not to freeze to death by buying $30 lightbulbs because you don't realize the heat coming from the $1 lightbulb isn't doing much harm at all.

• Turn off outdoor holiday lighting before bed or use a timer to automatically turn them off when you go to sleep.

Put all your outdoor holiday lighting inside (see previous point)

New Year, Same Stories, Old Professions

 Goodbye 2011.

This blog was new as 2010 turned to 2011. My first post of 2011 noted huge exports in December of 2010, negative pricing records for January 1, 2011, and record wind production in hour 21 of January 1st. It took about a week before the first reporter picked up on the subsidized exports story, which generated some interest in the mainstream media (MSM). Remarkably, in hour 18 of January 1st, 2012, wind would again set a production record (1633MW).

Comparing the immediately available data for New Years' Day 2012 to the 2011 data, we see why the price disaster of 2011 was curtailed, to only intermittent periods of negative pricing, this year.

Nuclear was idled: one unit at Darlington just for this weekend (we'll see if they get it back up for tomorrow's deep freeze), and one at Pickering they seem to have decided not to bother with this season (a Bruce A unit is also offline for a fairly substantial project).

Net Imports are only up compared to last year: 1/1/2012 we were still a net exporter - of over 1000MW/hour
