I did a bit of homework. PG&E publishes their rate schedules, of which they have many, and even a fairly cursory read strongly suggests that both the cost breakdowns and the times associated with time-of-use rates are, to put it mildly, divorced from any realistic estimation of actual costs. (Check out how inconsistent the schedules are from each other!) Here's the "Business Electric Vehicle" schedule, which appears to be the relevant one from EV charging stations: https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_EV2%20(Sch).pdf https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHED... Roughly 38c/kWh peak and 16c/kWh "super off peak" plus $1.24/kWh monthly for maximum load. (So a supercharger would pay some $248/month for the privilege of being connected, and peak shaving can reduce this.) Here's the current residential schedule: https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_EV2%20(Sch).pdf https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHED... Wow, 62c/kWh peak and 30c/kWh off-peak. At least the times kind of line up. Here's the legacy ones, with totally different off-peak times! https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_EV%20(Sch).pdf https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHED... Anyway, the morning-to-mid-afternoon rates in CA for public chargers are high but not outrageous.
