NEM-PS Annual True-Up Calculation [PG&E example]
- Thread starter aesculus

NBCs are charged for each kWh that you use from the grid. So, it makes no sense for anyone here to speculate how much you might accumulate in a year.
For example, one user here accumulated over $500 in NBCs because they use Grid Charging and Export Everything to get NEM credits to balance out their already high net consumption. I had never seen such high NBCs because I had never considered doing such a thing.
Oh sorry, I meant MBC. does MBC include taxes and fees? My NBCs are getting close to the MBC but if it includes taxes and fees then I have more wiggle room.
I think you still have the wrong acronym. Minimum Delivery Charges?
The first post in this thread covers the different cases and how to calculate the final amount owed based on which item is the largest. You will never pay less than the Minimum Delivery Charges unless you earn Net Surplus Compensation which could pay you back some or all of those charges if you have enough surplus kWh.
You mean MDC or Minimum Daily Charge which is compromised of all the various unbundled fees. This is currently $0.37612/day, for 365 days that is $137.28.
This guy needs to teach a energy billing class at the local JuCo. But he needs to grade on a curve or everyone is failing.
But a year is 365.25 days??!! What happens on the leap year? Do you get hit with the rounded up full day?
This is a leap year and February 29th is a day, so yes there is another $0.37612 due. No extra charge for the leap seconds though.
Isn't that a 26% increase? Like wtf... are they disproportionately applying the GRC rate increase to whack certain customers more? Presumably people with EVs also tend to be higher income. Many people don't have solar arrays that cover 100% of their annual consumption.
Close but it is "only" 23.88% (0.34462 vs 0.27818). The other rate periods have less than an increase which impact the people rate arbitraging with Export Everything and Charge From Grid. At $0.34462 that may change the dynamic for DC fast charging outside of the home versus in-home charging for some. The rate at the Tesla SuperCharger I used in Roseville last week was only $0.29.
| EV2 Period | Jan'24 | Sep'23 | Increase |
|---|---|---|---|
| Summer-Peak | 0.65713 | 0.59068 | 11.25% |
| Summer-Part | 0.54664 | 0.48019 | 13.84% |
| Summer-Off | 0.34462 | 0.27818 | 23.88% |
| Winter-Peak | 0.53002 | 0.46357 | 14.33% |
| Winter-Part | 0.51332 | 0.44687 | 14.87% |
| Winter-Off | 0.34462 | 0.27818 | 23.88% |
And for me with E-TOU-C
| E-TOU-C Period | Baseline+ Jan'24 | Baseline+ Sep'23 | Increase | <Baseline Jan'24 | <Baseline Sep'24 | Increase |
|---|---|---|---|---|---|---|
| Summer-Peak | 0.61806 | 0.53933 | 14.60% | 0.51250 | 0.45082 | 13.68% |
| Summer-Off Peak | 0.53462 | 0.45589 | 17.27% | 0.42906 | 0.36738 | 16.79% |
| Winter-Peak | 0.51536 | 0.43662 | 18.03% | 0.40980 | 0.34811 | 17.72% |
| Winter-Off Peak | 0.48701 | 0.40827 | 19.29% | 0.38145 | 0.31976 | 19.29% |
BTW, I would treat those Summer rates with a grain of salt as PG&E is already lobbying for yet another rate increase.
Ah ok I was basing my base rate on this picture. this is why I would get a F in your class.
Edit: Do you keep a running spreadsheet of all PG&E ETOU and EV2A rates? haha
Only for the E-TOU-C, but I've kept PDFs of the E-TOU-D, EV2 and E-ELEC to reference when I'm interested in something. There are also historical rate Excel sheets here: Rates and Tariffs
It's a safe bet that the rates will increase again before the Summer rate season actually starts.
Time to redo the GC/EE spreadsheet, sigh…
But I suspect as a net importer…as long as the arbitrage is > then the NBC’s (not taking into account wear on PowerWalls) then GC+EE is in my favor.
The spread went from 0.31250 & 0.18539 (summer / winter 2023) previously to 0.31051 & 0.18540 (summer / winter 2024). Then you derate by 10% for round trip losses…and you still have a credit that is > the NBC costs on the import. So I still think max GC+EE makes sense to offset my net import.
I might also add incompetence to the attributes...I mean who thinks that a high voltage insulator worn 90% of the way through a support is ok to leave for next year?
Pretty sure the CARE/FERA rates didn't go up nearly as much... the spread between the normal rates and low-income rates continues to widen.
