Henvey Inlet isn’t harbouring honesty

A short post to debunk some belligerently dishonest claims regarding Ontario’s most inane electricity/social science project, Henvey Inlet Wind.

Background: Clement/Thibeault $billion negligence: Henvey Inlet Wind

The contract, according to the IESO’s contract list, was signed in June 2011 under the feed-in-tariff (FIT) program that paid $135/MWh, plus up to another $15/MWh as an “Aboriginal Price Adder.” While those contracts were expected to be operational 3-years after the project data, apparently this one is exceptional in ways other than costing $150/MWh (roughly 5 times what new 2019 wind in Alberta will cost).

Here are the claims I’ll rebuke (emphasis added):

Development of wind energy will help Ontario in meeting its goal of phasing out coal-fired power generation.

The windfarm is expected to displace 851,000t of carbon dioxide emissions a year, which is equivalent to the amount of carbon dioxide released by 200,000 cars. It will also offset 4,100t of sulphur dioxide, 1,200t of nitrogen oxide, and 13.4kg of Mercury emissions per year.

Unlike coal-fired power plants, the project will not use water leading to the conservation, which normally uses approximately two billion litres of water a year.

The project, of course, missed the coal era in Ontario’s electricity sector. The “goal of phasing out coal-fired power generation” is long since met.Read More »


The IESO’s June mistake, and the July victims

Ontario’s electricity system operator (IESO) made a mistake in June.

In July they made it better for themselves in a way that specifically punished one set of consumers – Class B ones not covered by Regulated Price Plans (RPP). The OEB’s lacklustre oversight in recent years continues to harm this same set of consumers. This will be a wonkish post but if you’re connected with a company with a substantial electricity bill, it will alert you to probable overcharges.

This situation should be difficult to explain, because I’ve had friends questioning the IESO on it for half a year and I haven’t seen any evidence that a fulsome explanation is pending. That may be due to the beginning of the tale.

2017 IESO global adjustment consumption page on Feb 10

The beginning was the final global adjustment calculations the IESO made for June 2017. They erred in calculating total consumption. The inability of the organization to admit that, along with the regulator’s (OEB) disinterest in monitoring the IESO’s collection of global adjustment charges, is why confusion persists.

I noted on Twitter when the figures were released that they made no sense. To explain why requires getting into some obscure details.

  • the IESO reports “Ontario Demand” hourly, but that figure is essentially demand for supply from their market participants,
  • the IESO elsewhere reports a summary breakdown of this figure as “Monthly Energy Demand” which shows some of that figure is “Generator Consumption” and some is “Losses”,
  • the IESO has not reported on generators embedded in the Local Distribution Companies (LDC’s) it services, but in the past couple of years it has noted monthly distribution-connection (Dx) figures in it’s 18-Month outlooks,
  • the Global Adjustment process requires knowing the share of consumption for each consumer, so that reporting includes a “consumption” figure .

If you took the time to subtract out the generator consumption and losses from the IESO’s reporting of “Ontario Demand”, and added the embedded generation, you’d find you were usually about 1% short of the consumption as shown in the global adjustment reporting.  In June 2017 the difference was far greater:
