Got my first electric bill from
Portland General Electric with the whole month on time-of-use and with Mikiko charging every night (28 days of service).
At the end of the day though, I spent about $0.014 per mile assuming all my other electrical usage stayed the same. For our household, March and April are usually within 4-5 kWh, so I think we've very successfully shifted the majority of electrical usage to off-peak hours, here's the breakdown:
153 kWh (16%): On-peak @ $0.13266/kWh
152 kWh (16%): Mid-peak @ $0.075/kWh
653 kWh (68%): Off-peak @ $0.04422/kWh
The math won't add up since I'm not including distribution/transmission charges, Green Source charges, and taxes/adjustments, but should still give a good idea of what an electric vehicle might add to your bill every month.
Time to get out and drive!
