I suppose you don't use much electricity betw 2pm - 9pm ?gascant wrote:I got my first month of E9A bill--about $43 to go 1500 miles. Nearly all charging done at off-peak times. Not bad.
Keep in mind that Peak is only for half the year so E-9A can still cost less than E-1 when computed over a year. Of course it is difficult to calculate without having a history of hourly electricity usage of at least a year and an idea of how much one plans to drive the Leaf over the course of the coming year.mxp wrote:I suppose you don't use much electricity betw 2pm - 9pm ?
What kills the E-9A option for me is I have a growing family that consumes electricity heavily from 5pm - 9pm. I need to stay on E-1.
This spreadsheet is essentially worthless if you have a PhotoVoltaic System - your peak kWh usage under E9A could be NEGATIVE for 5 or 6 months of the year, creating "revenue" to offset your off-peak EV charging! Note: you can't actually make money, just reduce your bill towards zero.yogi wrote:I'm not sure if anybody get to use this excel form where you can input your usage and get comparison for E1( before and after the EV) , E9a and E9b.

The above spreadsheet provided to me by PGE project specialist when I asked for 2nd meter installation.
My wife likes the house at 78, so on hot days, we'll get AC starting up around 4PM. Can only imagine what it will be like this weekend! At least, most of the time it will be off-peak. We're just making a lifestyle adjustment--weekday laundry before Noon, dishwasher after Midnight. LEAF charging exclusively from 12:10 - 5:00 AM. For us, the 2nd meter might save $60/month if that, so it's a big investment to make for a small savings.mxp wrote:I suppose you don't use much electricity betw 2pm - 9pm ?gascant wrote:I got my first month of E9A bill--about $43 to go 1500 miles.

Good point, Ray; PV systems should favor a southwest orientation for TOU rates. Our older 1kW system (circa 2002), installed on the back roof of the house, faces Southeast, but ... our new 2 kW system, installed on the family room addition to the original house faces Southwest.planet4ever wrote:The real problem I have with E9 is that my solar system peaks well before 1 PM in the summer, despite DST. (Like much of California, our city is laid out parallel to the valley, so "south" is really about 20 degrees east of true south, and that's the way my solar panels face.) I have the E6 rate, with peak starting at 1 PM, not 2 PM as with E9. That's an hour of prime generating time that PG&E would not be paying me peak rates for if I was on E9.
Yes, I see your emoticon, but seriously, this is something people need to think about before they switch plans or get a solar system. The time of day differential is really nice for half the year (sell excess power to PG&E during the afternoon at 30 cents/kWh, buy it back for 5 cents/kWh after midnight) but for the other half of the year you only gain 5 cents/kWh.rclams wrote:I assume you know that we have 122 days till we need the Winter chart?planet4ever wrote:I assume you do realize you are showing the "summer" rates, May-October.
