Doesn’t picking the variable rate plan mean your day time costs are priced higher? It does where I am. It’s 10c/kWh on the regular plan but on variable it’s 14c during the day and 7c off hours.
So you're paying a marginally higher rate almost all day on variable-rate, but substantially higher 5-9pm. The math pencils if you have a home battery you can use to load-shift, or perhaps drive an EV a lot.
(Also: this structure is clearly designed around summer cooling load, but peak load is actually winter heating. I don't know what SCL is thinking.)
The morning and evening peak loads are about the same. But in the morning, hydro generation is higher, because the Skagit dams hold back water overnight and spin up for morning peak. Evening peak is when there isn't that excess generation available.
Honestly my biggest draw is charging my car, so I scheduled that. I do have a 3kWh LFP battery I have as an emergency supply, and since it's in my office anyway I charge my laptop off it, and schedule the wall plug it's on. I scheduled the AC to move the house temp up or down at night. On especially hot or cold days I'm sure I'll use it more at other times. :)
