Here’s the PG&E (utility) TOU grid for an EV-A Residential Whole House Service Electric Vehicles rate schedule, overlaid with with points for every hour for 2/3 of a year. Features of TOU schedule:
- 6 different rates for generation and distribution based on season and TOD
- 2 schedule variants - one for weekdays and one for holidays/weekends (HOWE = TRUE)
- Winter HOWE (in blue) looks a little less dense than Summer HOWE because this is only 2/3 of the way through the year.
As I mentioned, my first step in computing TOU costs is decorating each hour with it’s TOU rate, for subsequent calculations. I had to do this chart just to make sure my logic for TOU determination was working correctly.
I think just getting this right and showing outputs and doing export in terms of the different TOU rate schedules would be huge. We know the aggregated prices for each of these.
