PG&E Rates w/ solar & ev

Fri Feb 11, 2011 12:11 pm

I've just installed a 4.3kW Solar Panel system and will (Nissan willing) get a LEAF next moth, so I have 2 applications pending w/ PG&E (solar and EV).
I have been contacted by a PG&E guy who said that I cannot use the E9 w/ solar, since they will not credit me back the extra production.
The only rate I can use (and get money back for extra production) is E6.

Anyone else out there who can shed some light on this? I thought that PGE would credit back for the extra production regardless on the rate....

any help is appreciated.

I don't believe this is correct unless you are talking about the E9B rate which is when your electric vehicle is charged on a separate meter from the home and solar system unlike the E9A rate when everything is on one meter. Was this PG&E guy from the Clean Air Vehicle department? Perhaps a call to the Clean Air Vehicle hotline at (800) 684-4648 would shed some light.

In fact I plan to stay on the E9A rate when I eventually get solar and no one has said that would be problem for net metering.

I believe I am on E9A with net metering (kV2cs net meter). PG&E told me I could net meter with E9A. A few other guys on this thread are trying to choose between E6 and E9A:

I also have a net meter for E9A with my solar.

So it appears (and why I am not surprised...) that the PGE guy did not know what he was talking about...

When you have a net meter and produce more than you use, what rate does PGE use to credit you back?

They pay the same rate you would pay if you were buying power from them at the same time! Apparently we are very fortunate in that. From what they are saying down south, generation costs and distribution costs are handled separately, and I think I read that they charge you distribution costs for the electricity you sell them. PG&E does all of its calculations using bundled rates, so in effect they even pay you for the distribution costs. That makes sense to me - after all, the electricity you generate is really being used by your neighbors, so it reduces the amount PG&E has to distribute through its network.

The best part of it is that they pay you peak rates (weekdays) for much of the electricity you generate, and then you can buy it back from them at night at off-peak rates to charge your LEAF. So, for example, you might sell them 20 kWh at $0.30/kWh and buy it back for 0.10/kWh, meaning they would be paying you $4.00 per day to let them use your electricity for 12 hours.

Ray,

If you are certain about that, then the E9 rate would seem to be the way to go, since I produce much more than I use from 9 am to 4 pm (during the E9 peak) and use it during E9 off-peak.
Do you have a contact a PGE?

Hope it was that simple. With E9, the off-peak starts at mid-night, which is a problem for most houses. I have an E6 and after 9pm, my family is free to do anything. So we do the dishwasher, laundries, vacum, occasionally AC during summer, etc after 9pm.

Moving to E9a would be a life style change. I am going to use E6 for sometime and see it affects my billing.

Also remember, if you are power user of LEAF, then you might consume the entire Teir 1 of your off-peak just for charging your car. So for the rest of it, you will be using Tier 2 and Tier 3 of your off-peak. So you have to compare Tier 2/Tier3 of E6 and E9 also. I was seriously considering E9b, but having double thoughts because of the installation cost and other uncertainties.

Oh, I'm certain, all right, at least for E6. I've been watching and analyzing my E6 bills carefully for four years. I'm sure E9 works the same way, because the E9 tariff wording is the same as E6 on that matter.

Fabio wrote:... since I produce much more than I use from 9 am to 4 pm (during the E9 peak) and use it during E9 off-peak.

Actually, the E9 peak rate applies from 2 PM to 9 PM weekdays in the summer. The E6 peak rate applies from 1 PM to 7 PM weekdays in the summer. Since a typical solar array produces its maximum power around 1 PM in the summer and stops producing around 7 or 8 PM, you can sell more power at peak rate using E6 than E9.

In fact we usually start using more than we are generating around 5 or 6 in the evening (especially May to July), so having peak from 7 PM to 9 PM hurts us. The switchover comes even earlier by August, because the days are getting shorter but we're using more air conditioning. And as leaf561 pointed out, E6 goes off-peak at 9 PM, while E9 doesn't go off-peak until midnight, so that's three more hours of partial peak which also hurts us.

No, I've never spoken to them. I just trust what their official tariffs say.

I'm on an E9A rate for the Leaf. I'm finishing a small (1.6kw) solar project and turned the paperwork into PG&E to go to net metering. Apparently if you are already on E9 and want to stay on E9 there is a $228 "reprogramming charge". What a pain. He said that if I switch to E6 or E1 for even one month and then switch back, I don't need to pay the fee. I don't think either would be a big difference in the bill, certainly less that $228.
