What does DR - Coastal Baseline Region 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 | $196 | $2,350 | 48.3¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $394 | $4,726 | 50.0¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $551 | $6,618 | 50.5¢ / 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 |
|---|---|---|
| off-peak | 41.15¢ up to 11.7 kWh daily51.81¢ | midnight–midnight, June–October |
| off-peak | 41.15¢ up to 11.96 kWh daily51.81¢ | midnight–midnight, November–May |
Plus a fixed charge of $0.79343 per day — so longer months cost more before you use a single kWh.
Should you be on DR - Coastal Baseline Region?
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 $555 and February about $296. That $259 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.
There is a usage cliff to watch. The first 11.7 kWh you use each day are billed at 41.1¢; past that line the rate steps up to 51.8¢ — 26% more for every unit after. The last kilowatt-hour of a heavy month is the expensive one, which is why cutting a little off a big month saves more than cutting the same amount off a small one.
Before a single kilowatt-hour moves, this plan charges $290 a year in fixed fees. On the apartment above that is 12% 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.

Who can be on San Diego Gas & Electric’s DR - Coastal Baseline Region?
Eligibility is not our judgement — it is written into the tariff San Diego Gas & Electric filed. This is what that document says:
in single family dwellings, flats, and apartments, separately metered by the utility; to service used in common for residential purposes by tenants in multi-family dwellings under Special Condition 8; to any approved combination of residential and nonresidential service on the same meter; and to incidental farm service under Special Condition 7. This schedule is also applicable to customers qualifying for the California Alternate Rates for Energy (CARE) Program and/or Medical Baseline, residing in single-family accommodations, separately metered by the Utility, and may include Non-profit Group Living Facilities and Qualified Agricultural Employee Housing Facilities, if such facilities qualify to receive service under the terms and conditions of Schedule E-CARE.
Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.
If this is new to you
- Tiered billing for electricity: why the last kWh costs more
A cheap allowance, then a cliff. Where the cliff sits is the whole game.
- 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.
