In anticipation of getting my Model S, I switched to the E-9A plan last month. I decided to do this now after I did some calculations based on historic hourly usage data that is available for the months we have had our Smart Meter. Today I got my first bill under the E-9A plan and my average rate is actually two cents lower than with the previous E-1 plan (same consumption): $0.20 versus $0.22.
Per my bill, I was charged the following rates:
Summer Peak Usage
Baseline Usage: $0.30178
101-130% of Baseline: $0.31994
131-200% of Baseline: $0.50036
201-300% of Baseline: $0.54036
Summer Partial Peak Usage
Baseline Usage: $0.09876
101-130% of Baseline: $0.11692
131-200% of Baseline: $0.29734
201-300% of Baseline: $0.33734
Summer Off-Peak Usage
Baseline Usage: $0.03743
101-130% of Baseline: $0.05559
131-200% of Baseline: $0.15808
201-300% of Baseline: $0.19808
Winter Partial Peak Usage
Baseline Usage: $0.09864
101-130% of Baseline: $0.11679
131-200% of Baseline: $0.29721
201-300% of Baseline: $0.33721
Winter Off-Peak Usage
Baseline Usage: $0.04680
101-130% of Baseline: $0.06495
131-200% of Baseline: $0.15808
201-300% of Baseline: $0.19808
Note that winter rates are in effect since 11/1, and there is no winter peak rate apparently.
Assuming that when I get my Model S I'll stay within my current tiers, I will be paying about 20 cents per KwH if I charge my car in the off-peak hours. That amounts to about $71 added to my bill each month with 1,000 miles per month driving.
Still pretty cheap compared to my current Kia Optima's fuel cost of $280 per month.
I don't know the rates for Ties 5. But I'm looking forward to the new EV schedule where they will do away with tiering all together. Does anyone know if that schedule has been approved and when it will become effective?
Thanks for posting the actual E9 rate. I am also in the process of switching over to E9a now that I have my MS. Do you happen to know the kWh quota for each tier? I understand it varies from region to region? But I can't imagine it being too much difference between Menlo Park and East Bay. I can't seem to find this information in PG&E website. Based on your calculation, how much $ per month will you be saving once EV rate becomes available in summer?
