The top-end rate with PG&E is not way higher than $0.50/kWh. If you're paying $500/month with no AC and no homelab or whatever then you have something else sucking up vast amounts of power and you should spend some time with a killawatt measuring your appliances.
It seems to have gone down a bit this year though. These are the numbers from 2024:
Peak pricing: 0.53 + 0.183 = $0.71 kWh
Note that peak is 4pm to midnight, so basically all the electricity-using hours one usually would be at home if working regular hours at the office (like we do). Off-peak is a bit cheaper but we're either sleeping or out of the house so not very helpful.
