The Star article is a rehash of the nonsense spread by ENGO's last year, instigated by The Star's Liberal masters as part of a renewed campaign to re-ignite the dishonest campaign that preceded the relatively decent period when Chris Bentley was the Minister of Energy.
The material to construct the article is apparently something delivered to the IESO by Navigant consulting: Navigant designed the global adjustment mechanism in response to Dwight Duncan's desire, back in 2005, to force down rates of public generation in order to fund private projects (explained here). The IESO is currently holding stakeholder initiatives built around the musings of consultant Navigant on how to further steal from residential ratepayers and their public generator in order to enrich the participants at the
Composition of Ontario's "Global Adjustment" Charge in 2012
I can breakdown the data to almost match the "interactive" pie chart in the Spears article.
The charts shows that nuclear's share of generation is far greater than it's share of the global adjustment.
But wait ... there's better stuff to be found in breaking down "Renewables"
Renewable is shown in my estimates, and by the Star, as comprising 17% of the global adjustment, and I've got them at 25% of generation. Best deal ever - go ahead John, lie with that stat too.
The absolute disgrace is that Ontario's primarily public hydroelectric assets generated ~86% of 2012's renewable generation while receiving a feeble 29% pittance of the global adjustment destined for renewables (I estimate ~40% of hydro's 29% went to the various private companies for the ~6% of hydro generation they provided).
Understanding the relationships of cost is not hard if one ignores the global adjustment - the stuff that is $135/MWh, and the government is attempting to add 6000MW more of, is going to drive up the price more than the stuff that is ~$60/MWh and is not anticipated to grow.
Adding in the global adjustment is often done to obfuscate.
Pretending that capacity payments to keep coal and natural gas capacity available aren't related to both intermittent renewables and an extremely high (carbon-free) baseload capacity allows for a comparison (still flawed). I previously posted a chart indicating the share of generation, the share of the global adjustment, and the difference in those percentages: it demonstrates the hydro heist, as well as the contribution of nuclear generation significantly exceeding it's share of the global adjustment.
