Move to SMUD territory :P

For normal whole-house rates they now only have two tiers (used to be three) based on usage. In round numbers, anything (each month) after 600kWh (or some rates 1000) is 18c, below that level 10c/kWh for Winter (Nov 1-Apr 30). In Summer: Tier II is 19c, Tier I 11c.

(It's more complicated and a few other factors ... but won't affect many. If you want details: http://www.smud.org/en/residential/rate ... ts/1-R.pdf )

TOU is available: Winter: 10/11c for Off/On-peak. Summer: 10/16/24c Off/On/Super-peak.

For EVs you need a 2nd meter. Then you can put the house on either regular or TOU, but EV on TOU: Winter: 7.5c/11c (Off/On-peak); Summer: 8.4c/24c. So all you need to do is avoid the 6 hour Summer On-Peak 24c rate between 2pm-8pm.

The PG&E electric vehicle E9A Summer peak rate at 201% baseline usage (tier 4 of 5) and higher maxes out at $0.56915 currently. Hopefully I will never be charged that rate but as I drive my Leaf more I am going to be close. I am already in tier 3 territory now. Once I cross over into tier 4 territory its time to seriously consider installing solar.

I should add that my baseline per day is 12.1 kWh Summer and 12.6 kWh Winter and my last billing month with the Leaf I averaged 21.3 kWh per day.

E9A is when the whole house as well as the EVSE is on one meter and thus the same rate.

Assuming you have an appropriate location, wouldn't solar give you a very good payback?

Finally getting data from both CARWINGS and the Blink. Yesterday's drive:

CARWINGS 6.3 kWh
Blink 9.4 kWh

I'm assuming CARWINGS is reporting consumption by the car, and Blink is reporting consumption by the charger. So does 68% efficiency from wall-to-wheels sound about right? I'm new at this EV stuff, so I just want to know if this is within expected parameters. With gas at $3.75/gallon and electricity at $0.12/kWh, I'm still getting the equivalent of 90 MPG.

Seems to me your consumption rate is in the ballpark, based upon what other drivers have posted so far.

It is believed that the kWh value reported by CW is incorrect (too low), especially when the Regen kWh is high.

I believe that the Regen kWh is incorrectly handled when the "total kWh" is calculated.
