Even my electricity bill hasn’t gone up much. Maybe about $20 a month from what I was paying (my rate is $0.067/kw).
I'm envious. In CA I'm paying around 28c/kWh, which is pretty close to the same cost as gas. I could switch to an EV TOU rate schedule that would reduce dead-of-night use to 13c/kWh or so, but then my daytime rate would go up to over 40c/kWh, so will have to do some modelling to see if that makes sense. At least PG&E does make the hourly usage data available for modelling purposes - for a bit I thought I'd have to cobble up my own meter reading device from a Raspberry Pi + radio module.
