What does Residential Service - Underground Electric Space Heating cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $62 | $749 | 15.4¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $119 | $1,433 | 15.2¢ / 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 | 17.45¢ | midnight–midnight, June–September |
| off-peak | 12.13¢ | midnight–midnight, October–May |
Plus a fixed charge of $6 per month.
Should you be on Residential Service - Underground Electric Space Heating?
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 $198 and February about $78. That $119 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 $72 a year in fixed fees. On the apartment above that is 10% 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.
