Interesting... SoCalEdison decrees that summer starts on June 1. Last I checked we get hotter than poop before y'all do up north, one would think SCE would start summer before PGE. Go figure. Not that I'm complaining...
What I am inclined to complain about is the SCE summer pricing... currently published Tier 1 peak rate is about 3x the super-off-peak (12am-6am) rate, and the Tier 2 is over 5x ($0.09 vs $0.47)! I suspect the PGE rates would result in lower bills for someone with my home + EV electricity needs, which end up well over Tier 1 cutoff. Worst of it is that the Tier 2 off-peak rate (6pm-12am, 6am-10am, weekends/holidays) is $0.28/kWh, 3x over Tier 1. I haven't done the calculations, but now I might have to seriously consider buying an L2 EVSE to keep overnight charging within the super-off-peak hours - currently I need about 12 hours on the OEM charge cord to get a full charge after coming home from work.
