Carbon-Con: ECO communication

A couple of weeks I was asked about potential ways to collaborate with reputable sites. I put some thought into that before responding that simply an association with me could bring a site to disrepute, but my thoughts on communication persist. From the belligerent uttering of a federal Minister on a Sunday talk show, to a media blitz from an organization marketing itself as expert on economic tools to reduce carbon emissions, to the Ontario report I'll feature in this commentary, it's been as if a convention of climate change alarm is occurring.

A Climate convention.

Comic Con (short for convention) is a really big event now, which makes some sense in this era of communication. Text is a low impact medium - the sites adding audio and video, integrating with podcasts, have a huge advantage. As the comic and related genres (science fiction, fantasy and superhero) grew from print to screens of all sizes, the graphics and sound growth has simply piled success onto success. The term "simply" recognized almost all characters can be grouped into good or bad.

Perhaps due only to my musing about communication, collaboration and branding, I thought the polarized nature of climate, and energy discussions, make Comic Con a model for communication and promotion in the 'clean tech' industry.

I'd prefer to be a hero, but realize the model needs villains too.

What I hope will be found in my little section of this Carbon Con is data-driven iconoclasm delivered thorough research, competent data handling, pointed if not visually appealing graphics, and full contact criticism of those blissfully unaware they deserve to be blisteringly opposed.

What many will find is villainy - I've been accused as anti-wind, anti-renewable, anti-conservation, pro-nuclear, disrespect and misogyny. I don't agree with that entire list, but I'm okay with being the villain if it makes for better heroes.

My concern with the profession of professing concern about carbon emissions begins, as most things do, with religion.

Base load and baseload generation

The term baseload gets thrown around frequently but seldom is associated with a base, or minimum, load. It occurs to me the level of knowledge in discussions on electricity supply could benefit from reviewing the level of total electricity that would be met by a mythical generator running throughout at a the year at the minimum system demand. The results are not surprising,but the current level of discourse indicates the results are not intuitive.

I’ve revisited hourly load data I’ve collected over the past year for two provinces and British Columbia (bce … or BC). Each data set measures “load”, or demand, differently, but the particulars are not important for this simple review. For each province’s data set, I’ve queried the minimum annual load along with the average. Upon reflection it’s obvious that the minimum load divided by the average load produced the percentage of annual supply that could come from the steady production of the minimum load.

Differences between years are minimal, but the difference between Alberta and the other 2 provinces is significant. Alberta’s flat load profile means 80% of annual generation could usually be met by consistent supply at the base load level. “Alberta Internal Load”, or AIL, is the statistic used, and it includes behind-the-fence generation which is large due to extensive cogeneration, particularly from oil sands operations. Large industrial loads tend to be far more consistent than, particularly, residential demands. In Ontario and BC the reported loads, which omit behind-the-fence generation, indicate over 2/3rd of supply requirements would be met by output at the base load level.

For reasons I’ll return to in discussing implication of this base load supply level review, I ran some figures estimating how much usable supply would come from increasing the base supply level to 10% above the annual base load level, and with base supply 20% above base load.

Transmission constraining Ontario's Niagara Hydroelectric potential

I was recently asked why I claim there are transmission constraints on electricity generation from Ontario Power Generation (OPG) Niagara river system generators.

I’ve written a number of times on production levels and argued the constraints largely because I have consistently found the actual output from OPG’s 5 Niagara system generators less than it could be. There are current reasons to revisit the issue:
  • In 2017 the total was 11.32 TWh[1], which is probably the lowest level since I first appeared, in 1965,
  • OPG reported 4.5 TWh of "forgone hydroelectric generation" due to surplus baseload generation (SBG) in the first 9 months of 2017, up 15% from 2016 when OPG's annual foregone generation was 4.7 TWh, 
  • OPG intends on adding 106 megawatts of capacity through an overhaul of  two idled old units at the Sir Adam Beck I Generating Station
I’ll review the annual generation data but acknowledge the lowered generation doesn’t prove a transmission constraint - so I’ll also build a timeline demonstrating increased transmission was deemed necessary a decade ago, and the need must have grown significantly, along with generating capacity in the region, since then.

My curiousity on the topic of foregone generation was piqued in June 2011 by an article in the Buffalo News.[2] The article discussed Canada’s inability to utilize all the water it had rights to in generating electricity on the Niagara river, and OPG's Niagara Tunnel project that was to address that, increasing generation by 1.6 TWh. In March 2013 the tunnel was declared, by OPG, to be in-service.

By 2014 I was utilizing Hourly Generator Output and Capability reporting from Ontario’s system operator (IESO) to collect data on individual generators[3], and U.S. Energy Information Administration (form EIA-923) data for the generators on the U.S. side. The comparisons showed OPG output falling far behind the U.S. generation on the Niagara river[4] - a trend which has since, surprisingly, accelerated.

When the output at OPG’s generators did not increase after the Niagara tunnel project completion, I looked for other causes.

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.
