Notes
- Annual amounts are estimates at current rates, not a forecast of future bills. Monthly amounts are the year’s total divided by 12.
- An approved rate change for Fixed Rate (RF01) takes effect on January 1, 2027, under Rate Schedule R (Residential Service). These estimates use the rates in effect now.
- An approved rate change for Time-of-Day (Low Use) Rate (RTL1) and Time-of-Day (5-8 p.m.) Rate (RT02) takes effect on January 1, 2027, under Rate Schedule R-TOD (Residential Time-of-Day Service). These estimates use the rates in effect now.
- Holidays listed in the rate schedules are billed like weekends. Usage on those days is also spread like a weekend day.
- Your monthly kWh is spread over the hours of the day with a typical hourly pattern for homes in Sacramento County, CA, derived from the End-Use Load Profiles for the U.S. Building Stock. The pattern comes from building energy models calibrated to measured data, not from your own meter, so your bill can differ.
- The apartment pattern is based on 444 building models, compared with 1,515 for houses, so it is less certain.
- Data includes information from the ResStock™ dataset developed by the National Laboratory of the Rockies (NLR) with funding from the U.S. Department of Energy (DOE). Licensed under CC BY 4.0.

What an EV adds on this plan
A house that uses 750 kWh a month adds an EV that needs 200 kWh a month at home, charged midnight–6 a.m. every day. Annual estimate at current rates, shown as a monthly average:
| Case | Per month | Increase |
|---|---|---|
| Without the EV | $150.28 | — |
| With the EV | $183.15 | $32.87 a month ($394.48 a year) |

How the estimate works
- For each month of the current year, your monthly kWh is spread over the days and hours with the typical hourly pattern for your type of home. Weekdays and weekends have different patterns, and holidays use the weekend pattern.
- If you shift evening use, that share of each day’s use from 5 p.m.–9 p.m. moves evenly to midnight–6 a.m., and your total use stays the same.
- Each hour is matched to the plan’s time period for that month and day, priced at the plan’s rate, and added up. The fixed charge (a monthly amount, or a daily amount times the days in the month), the per-kWh adjustment, and any credit you qualify for are separate lines. Each line is rounded to the cent, and the bill is the sum of the lines.
- The annual estimate adds up 12 monthly bills at the rates in effect now. Every plan gets the same usage, so the differences come only from the rates.
- If a plan’s rates are being rechecked, for example after a scheduled rate change, the calculator shows its estimate at the last checked rates and stops ranking it until the check is done.
