Also being moved to A, according to the letter we received. It's estimating energy costs at $0 and non-Energy costs at $11, vs. $9 on TOU-D-TEV.
smkettner said:Just started a new billing cycle and still SCE has me continued still on the old rate plan TOU-DTEV-SDP
smkettner said:I thought the two meters were on same bill and you just pay the total.
smkettner said:Typically once on net metering everything rolls forward a full 12 months before the full net cost is presented for payment. This is why it is called "Net Metering". You should be able to continue using the separate meter or the main house meter for the EV. Probably the solar only goes on the main house meter. But still it should be 'net' with the EV meter.
The advantage of your present separate EV meter is that you most likely have your house on regular tariff without TOU? I believe you are correct that SCE will not allow anything else connected to your EV meter, including solar. You might wish to confirm this by calling SCE at 866.701.7868, which I believe is specific for Net Metering customers.Valdemar said:I have a separate EV meter and toying with the idea to get solar added this year. Is there any good reason to keep my EV charging on its own meter and add solar to the house meter? As far as I remember SCE only allows solar generation on the non-EV meter.
EDIT: I suppose one benefit is that by the time I'm ready to pull the trigger the TOU-D-A plan will be no more, but as there will be no EV on it TOU-D-T won't be as penalizing for off-peak usage above the baseline and provide the benefit of the friendlier for solar generation on-peak window, i.e. I can likely get away with a smaller system and lower up-front costs but won't be able to offset EV usage by solar. I also want to know if SCE will allow a second solar array tied to the EV meter with separate net-metering.
smkettner said:TOU/Solar/EVs tend to go well together. If you are on TOU-A you may well be selling power at the on-peak rate at the same time you are consuming power at a lower peak rate for EVs. You are still better off to charge the vehicle off-peak. If you stay on schedule D you just reduce your net consumption so you are avoiding the higher tiers not selling at those rates.
Valdemar said:Thank you for the good info. Yes, I'm currently on the domestic tiered plan and the separate EV meter allows me to charge at 11c/kWh at night instead of 31c in the tier 4.
I called SCE again today and learned that they allow aggregation of several meters on a single net-metering plan and the lady on the phone said that getting my EV meter added should be no problem as it is on the same property, so smkettner is right. A special form is needed to request aggregation at the time you apply for net-metering. Now it gets interesting, if I understand it correctly when/if you sell excess power and charge your car at the same time you technically get paid 11-15c/kWh. Does it sound too good to be true?
I called SCE on the EV number, 1-800-438-4636. The lady was knowledgeable about the TOU-D-A tariff. Boomer23 is right, they will deduct $.10 per kWh up to your baseline allocation off the price for all 3 TOU periods. The $.10 deduction stops when you exceed the baseline allocation. So effectively, we actually have 2 tiers for each TOU period, not one as advertised.Boomer23 said:You got me thinking (read: worrying), about how SCE might finagle this weird baseline credit, and possibly do the double-negative thing and actually charge us ten cents per kWh that we over-generate. I highly doubt that extreme outcome would get past the uproar from both the solar PV user base and the solar industry after the first month's bills arrive. But I did some further searching to see if anyone has gotten a clearer answer as to how it'll work.
This link here will take you to a Tesla owner forum where they discussed this. If you scroll down to member DaveR75, you'll see a dialogue from an SCE rep on how it'll work. Granted, it's incomplete and it doesn't address solar users, but it does say that all users will get a monthly credit of $0.10 per kWh of actual usage (meaning net usage drawn from SCE's grid) up to their baseline amount. But for months when the customer uses less power than the baseline, the credit would be reduced accordingly. (Baseline is different for each city, but for example, for me in Irvine, winter baseline is 285 kWh and summer baseline is 313 kWh for some representative months. The actual baseline is a daily number of kWh, so the total baseline for a month will depend partly on the number of days in the month.)
That means to me that if a solar user generates power equal to his power usage for any month, he wouldn't get any baseline credit for that month. And in other months, if his net usage is let's say half of his baseline amount, say 150 kWh, he'd only get his 10 cent credit for that much usage, i.e. $15 for that month. You'd only get the full baseline credit in any month that you net use at least your baseline allocation.
Now, please correct me if I'm wrong on this, if your PV system is large enough that you always have a net usage of zero kWh, and if you're on a TOU plan and charging over night, you're probably sitting on a monthly credit that gets zeroed out at the end of the net metering year anyway, so you don't care that you'd miss out on the baseline credit. But if you're like most people and you use slightly more power than you generate some months, each month of the year will be a different story. If you use a lot of air conditioning in August, you'll have a net bill for Peak power usage and possibly not much if any baseline credit to offset it.
So how to play this game? Looking at my own usage over the last year, I'd only get the full baseline credit in November, December and January. So if that turns out to be true, for those other nine months, I'll be missing out on using some cheap kWh. Since the credit is 10 cents and Super Off Peak usage is 11 cents, any car charging or other power usage during Super Off Peak up to the baseline amount would only cost me a penny per kWh. And SCE has expanded Super Off Peak to include the ten hours of 10 pm to 8 am, every day. So you could probably move some of your laundry and dish washing into those hours, and maybe you could drive your EV more and do more charging at a penny per kWh.
Will it work out this way? We shall see. One member of that Tesla forum, "ARCHER" at the bottom of the page, says that he's been on Plan A since January, (I'm not sure how he got on the plan that early) and it hasn't bitten him in any strange way, so maybe some of our fears won't come to pass.
How will the bill credit be calculated for the NEM Aggregated arrangement?
The electrical consumption of kilowatt-hours (kWh) registered on each aggregated account’s meter will be reduced, for NEM billing purposes, by a proportional allocation, at the 15-minute interval level, of the electricity generated by the REGF that is exported to our grid. The proportional allocation is determined per billing period based on the cumulative consumption of each aggregated account compared to the cumulative consumption of your NEM Aggregation arrangement since the start of the relevant period, and the cumulative generation exported from the REGF since the start of the relevant period.
I wonder if that's related to/due to the work of ALEC (http://www.autoblog.com/2013/12/23/alec-coming-for-home-solar-power/" onclick="window.open(this.href);return false. :roll:Boomer23 said:I just found a page on SCE's site that is new to me, that explains how the baseline credit works in TOU-D-A, and I'm kind of floored by something they state:
https://www.sce.com/wps/wcm/connect/edc01054-c02e-4295-8d21-30c263b0b4e1/PEV_NEM_FAQs+v3_EP.docx?MOD=AJPERES" onclick="window.open(this.href);return false;
Basically they ARE going to CHARGE us solar customers the ten cent per kWh baseline credit amount for months in which we net generate power! So if we end a month with a net generation total of 100 kWh, there'll be a CHARGE on our bill for ten cents per kWh = $10 for having sent SCE 100 kWh of power! I still can't quite believe I'm saying that, but it's as plain as day in the example.
ALEC, a group of about 800 people that includes such notables as ex-vice presidential candidate Paul Ryan and Texas Senator Ted Cruz, appears to be going after any and all things related to renewable energy, and that includes people who install their own home solar panels and sell their excess power back to the grid. In fact, ALEC not only is saying these people shouldn't be paid for the energy, but believes they should pay for the privilege of sending energy back to the grid because they don't have to pay for the grid's infrastructure.
