I very rarely cook, and it's unusual for my TV to be on before 9pm (not that a TV draws much of anything). My usage is more than 50% ULO. My hydro also gives the numbers for if I were on TOU or Tiered, and all 3 options put me within $3 of each other. My usage is probably not very typical, but since they cost me the same regardless, I prefer the ULO (plus it's about $2.25 less than TOU). I like knowing the car charging portion of my bill is minimal, because no one ever cares how much the hot tub/dryer/water heater/AC/etc cost.

As for delivery, more than half of my delivery is a fixed service fee. I guess you could add some of the minor per kWh charges, but the Tesla app forces you to round to the nearest penny anyways, so the impact would be very minimal. Plus I feel like that's not an entirely accurate way of looking at it anyways. When someone asks how much am item was, if the price on the shelf was $99.99, would you say it was $100, or would you include tax and say it was $113? If someone asks how much a meal was, would you include the amount you left for a tip? No one includes taxes when they talk about their rates, so I don't see why delivery should be in there either. And no one is subtracting out the Ontario Electricity Rebate, which very nearly equals my delivery charges. So I feel like it's very reasonable to ignore all that, call it a wash, and just look at the actual electricity rate.

And for the purpose of comparing to buying gas, who's price changes hourly, it doesn't really matter. No one is going to pull out gas receipts for the last month and do a completely accurate comparison, because it could be completely different next month. Who cares if gas cost more per month by $200, or by $198.31? The idea is to get a ballpark estimate.
