Congrats!!! I'm also in Bakersfield. My off peak rate is $0.08/kWh, from 6 PM to noon. On-peak summer rate is $0.32/kWh. On-peak winter rate is only $0.12/kWh. I'm sure there's an increase in the electric bill, but it's probably not much, since I also have a solar PV system. I also got the Clipper Creek L2 EVSE, it's been very worthwhile, since I can go 100% EV on the weekend with multiple charges. What part of Bakersfield are you in? I'm on the east side. I saw another silver Volt here occasionally, his car has the VOLT sticker on the side.
