I am within a few blocks of the NW boundry of the SDG&E service area.

I have had the PV system operational for a little over a year, but their rate schedules are still a mystery to me.

The SDG&E Residential "Rates" include only the "distribution, etc." charges, and not the energy cost (approx. an extra 9¢ per kWh). One needs to find the Residential "Total Rates", which include the power charges.

They also appear to supply the "dual meter adapter" (for one EV rate), but then charge over $9 per month extra.

The "new" (experimental) EV tariffs are not mentioned, as far as I can see.

There are three EV rates, all TOU:

1. EV-TOU: shy 14¢ low, to 26.5¢ summer peak, 17.2¢ winter peak, including energy, no tiers, and about $5 per month minimum bill.

2. EV-TOU-2: seems basically the same as EV-TOU, but allows PV generation and net metering as long as all-users generation is less than 0.5% of peak demand.

3. EV-TOU-3: uses SD&E's "dual meter adapter" (extra $9.32 per month), with basically the same rates as EV-TOU.

So, looks like some good in these "standard" EV rates.

"Nothing good" is relative! We pay $0.56 per kWh summer peak up here in Northern CA!

The SDG&E Residential "Solar Power" rate (DR-SES) appears to be similar to the EV rates, but with a little higher charges, and TOU times changed a bit.

The standard Residential tariff (DR) "Total Rate" is tiered, with about 13.4¢, 15.5¢, 27¢, and 29¢ (including power) in the summer for tiers 1 (to 100% of base), 2 (101% to 130%), 3 (131 to 200% of base), and 4 (over 200% of base). The winter rates for Tiers 3 & 4 are about 2¢ lower than the summer rates.

Both have the approx. $5 monthly minimum.

I just called SDG&E again and left a message for their net metering department to call me back. This is my 2nd message, so we'll see if they ever call. I'd like to get to the bottom of exactly what I'm paying, how my net metering is being charged, and what the Leaf can/will do to my rates.

I just spoke to SDG&E and they tell me I'm on regular Schedule DR tariffs. I'm not on a solar time-of-use, which I find interesting. The DR rates start at $.03919/kWh and go up to $.19700/kWh for 200% or more of my baseline number. Since I generally generate a surplus, my rate doesn't affect me unless that rate is used for rebates. If THAT's the case, I want on the highest rate plan possible to generate the maximum rebate check.

Solar time-of-use rates are a flat $.10409/kWh regardless of time of day. (interesting)

EV time-of-use charges are around $.09/kWh, varying slightly depending on time of use.

Someone from SDG&E is supposed to call me back about the my options for an EV charging situation.

More when/if I find something.

Jimmy,
All the SDG&E "Rates" do not include the power itself, which is a "Schedule EECC Rate". The "Total Rates" include the power.

When you are "credited" for over-production, I believe you get the power-only "credit" (about 6.6 winter or 9¢ per kWh summer in the basic "DR" rates). The Total Rate includes "distribution, etc.", and the "power" portion, to make up the amount that you are charged.

So, high "Total Rates" might be OK here, even though you are charged these high rates when you under-generate for the month, if you do get a higher credit when you over-generate for the month (just getting credit for the power).

At least, this is how it appears so far.

Actually, pretty sure you have it backwards - the rates he's looking at are the energy rates, not the distribution rates.

Remember - it's expensive to fire up those peaker plants on hot days to satisfy AC load.

No rates have been set yet for generation credits. Should happen by the end of the year.

So, no, you do NOT want high "rates" here, because you are charged these rates (plus power) when you under-generate for the month, but you do not get credit for them if you over-generate (just credit for the power).

At least, this is my best guess so far.

Note: Some of the rates seem to be LOWER in the ON-PEAK times, and HIGHER in Winter.

You might ask them about this. As stated, the Residential TOU rates would seem to encourage more usage at PEAK times.
Then I'm confused. Where do I find the actual charge for the power itself? I always thought it was included in all the tariff columns and the total (UDC) column was the price you paid per kWh.
