- off-peak15.35¢
What does Residential General Service Opt-Out cost a year?
| Household | Uses | Per year | Works out to |
|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $894 | 18.4¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $1,670 | 17.7¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $2,266 | 17.3¢ / kWh |
Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.
What you actually pay
| Period | Rate | Applies when |
|---|---|---|
| peak | 18.34¢ | midnight–midnight, June–September |
| off-peak | 15.35¢ | midnight–midnight, October–May |
Plus a fixed charge of $8.19 per month.
Should you be on Residential General Service Opt-Out?
The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $210 and February about $100. That $110 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.
Before a single kilowatt-hour moves, this plan charges $98 a year in fixed fees. On the apartment above that is 11% of the whole bill; on the house with a car charging in it, 4%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.
If this is new to you
- How to read your electric bill
Four kinds of charge, only two of which you can do anything about.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
- How to compare electricity plans without getting it wrong
Six things that break a comparison, and the order to check them in.
