Hydro One seem to have finally got their act together and launched ULO details plus a calculator -
Hydro One
We drive around 40,000km per year, always charge at night and are currently on the time of use plan; our daytime and evening use isn't excessive at all (our on-peak and mid-peak combined is 20% of our overall usage). The calculator tells me we'd be worse off with ULO by around $20 per month. Makes me wonder who it would be suitable for, seems pretty clear it's NOT for heavily used EVs, just some, even though the waffle says:
I kinda guessed this would be the outcome - they've been forced by some well-meant policy to do
something, and after months and months of work have figured out a way to seem like they're doing that while having zero actual impact to their bottom line or the intended goals. Amazing work, and very much in character with so many monopolistic sectors in Canada.
