Yes, I did. Talked to Matt (EV study guru) and Jennifer (Billing guru) - have one additional question that I'm waiting an answer for but they've been very responsive. Let me know if you want their contact details.lonndoggie wrote:drees, did you get an answer on your billing question?
My EV bill is combined with my gas bill, too. I believe this is done to keep the net-meter bill separate.lonndoggie wrote:1. Gas and electric used to come in separate envelopes. This time, both were crammed into one.
2. The EV meter is included in the gas bill! There is a note that this is for services provided by the Department of Water Resources. Which seems very wrong.
That seems wrong. My net-meter account has remained separate even though I got a new meter to go with the new EV meter.lonndoggie wrote:3. The former EV electricity account seems to have died; the $.85 I'd paid previously for 5 days at $.17/day minimum fee is the only usage shown. However, that also shows in the gas bill.
Yep, you definitely have something wonky going on.lonndoggie wrote:What's more, I'm being billed for 10kWh for May 7-June 13 (the day before I got my car)--so nothing but the Blink was on that circuit. Seems fishy. The electric service is listed as using the EPEV-Residential rate, but still, I wonder if they think they're billing me for a water pump?
Yeah, that's another thing I brought up in my inquiry--the start/end readings (for the net meter, not the EVSE) are zero, yet they show the delta they computed via other means.GroundLoop wrote:My Net Metering bill has been wonky since the EVSE program started.
I seem stuck on "0" for Start and End read values, even though the meter should be racking up (negative) generation credits this time of year.
Haven't tried to read it, so I've avoided that pratfall.GroundLoop wrote: Note that the A/B/C readings on the meter face are USELESS at best, and misleading.
They do not represent the EPEV time-of-day totals at all. They are based on a different timer set that means nothing.
Sounds OK to me. Except that this first bill with EVSE charges in the mix, I can see that didn't happen (the first part, the subtract; I don't have a bill for the EVSE meter yet where there was actually charging going on).GroundLoop wrote: SDG&E reads the 15-minute interval data from both meters, subtracts the EVSE from House at each interval, and then bins the EVSE consumption into the EPEV time-of-use bands for that bill.
Right, which is what I'm doing, via Energy Waves (https://energywave.sdge.com/), same as Dave. It's pretty easy, once you get the hang of it. Also using it, as mentioned above, to do a whole-year analysis of how moving to EV-TOU-2 would affect my bill.GroundLoop wrote: I'm having a hard time tracking my own TOU usage with this methodology. You really do have to read the 15-minute interval data to predict your bill. There is nothing on the meter face to help you.
Energy Waves appears to be pretty accurate. The trick is to make sure you read the proper days. If your meter read dates are July 8 and Aug 8, for example, you should include all interval data from Energy Waves from Jul 9 - Aug 8, from what I understand.lonndoggie wrote:So I'm left at this point with curiosities (why does it make up TOU usage numbers?), questions (is Energy Waves reasonably accurate?) and a billing problem (paying for energy pulled thru the EV meter twice).
I think/hope so, too. But the support folks have no idea about it, couldn't comment on the accuracy of it...not that that worries me much.drees wrote: Energy Waves appears to be pretty accurate.
Ah--that probably explains why my numbers for the last billing cycle were about 10kWh higher than SDG&Es.drees wrote: The trick is to make sure you read the proper days.
