oh, i care (and notice). not much that can be done about it though.
i haven't consistently downloaded the EV rate sheet to capture all of the changes. does PGE keep the historical tariff sheets on their website?
IMO this is why I think PV+ESS has an implied benefit that few people quantify. The PV+ESS effectively locks in rates, and is a form of a hedge against the PoCo. If you wanted to enter into a futures contract for 10 years of kWh rates right now, you won't find a broker. But, you can get a battery or two and are no longer tied to the PoCo's rate BS.
Regarding the historical rates; I don't think PG&E makes like a month by month dataset available... but I did jot these down for EVA
2016 Summer Peak $0.44 per kWh
2018 Summer Peak $0.47
2021 Summer Peak $0.56 (27% increase from 2016)
Of course, you should not charge your car during peak; but this rate hike is just killing you if you were cooking or running the AC like a normal person
Anyway, specific to the off-peak charging I have these rates jotted down.
2016 Summer Off-Peak $0.12 per kWh
2018 Summer Off-Peak $0.13
2021 Summer Off-Peak $0.16 (33% increase from 2016)
