Tier 5 peak use with E-9b? This does not compute. Are you planning to put more than 30 kWh/day into your LEAF between the hours of 2 PM and 9 PM? Actually, even if you did (not that it is possible), your net rate would be somewhat lower than that. I'm not sure what your baseline is, but let's assume it is 10 kWh/day.
$3.91 for the first 13 kWh
$3.19 for the next 7 kWh
$5.65 for the last 10 kWh
$12.75 for 30 kWh, or $0.425/kWh
But of course the whole point of using E9 is to charge the car at night when the rates are low. Under much more reasonable assumptions of a timed charge from midnight to 7 AM at 3.84 kW (trailing off at the end) you can charge from 'low battery' to full all in the off-peak period, using maybe 23 kWh.
$0.78 for the first 13 kWh
$1.50 for the next 7 kWh
$0.97 for the last 3 kWh
$3.25 for 23 kWh, or $0.14/kWh
