I know - it is complicated. The commercial rate here in Ontario for large consumers is based on the delta between expected load and actual load. If the expected load is much higher than actual, it can actually go into negative pricing (if they have a big nuclear reactor they can’t or don’t want to spin down, they will literally pay you to use the electricity.) I had a friend at a big company here that had some large refrigeration units for medical related stuff, but they had quite a wide range of temperatures they were allowed to be. So my friend wrote a script that scrapes Ontario Hydro’s website to fetch the commercial rate, and when it was high he’d let the temperature climb a little, and when it was low he’d cool the units a little more. Ended up saving seven figures a year.
