The cheapest plan here changes with how much you use. That happens where tiers reward a small household and a big fixed charge rewards a large one — so the right answer depends on your own bill, not on an average. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.

How much does the plan you pick actually matter here?

Run the same three-bedroom house with central air through every plan San Diego Gas & Electric Co files in Coastal Baseline Region, and the bill lands anywhere between $3,951 and $4,920 a year. That $969 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.

Those figures describe Coastal Baseline Region, because comparing across zones would be misleading: your zone is set by where you live, not by anything you can choose. The plan lists further down are grouped the same way, so compare inside your own group — your bill names it.

The plan most households land on by default, DR - Coastal Baseline Region, comes to about $4,726. The cheapest option here, TOU-DR-1 Coastal Baseline Region, comes to $3,951 — a gap of about $776 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.

7 of these 8 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.

Watch the fixed charges too. Across these plans they run from $10 to $290 a year before a single kilowatt-hour is counted. For a small household that difference alone can outweigh the per-kWh price, which is why comparing cents per kilowatt-hour on its own quietly misleads.

How San Diego Gas & Electric compares across California

Run the same three-bedroom house with central air through its default plan at each of the 5 California utilities we cover, and San Diego Gas & Electric is the dearest of the lot at about $4,726 a year; the state median is $3,585. The cheapest, City of Riverside, charges $1,672 for identical use — a gap set by the address, not by anything either household did.

The other two households tell the same story in different sizes: a small apartment pays about $2,350 here against a state median of $1,675, and the same house with an electric car charging overnight about $6,618 against $5,161. Effective rate, fixed charge included, is 50.0¢ per kilowatt-hour for the family home.

Inside San Diego Gas & Electric itself, the gap between its cheapest and dearest plan for that house is $969 a year — less than the $3,055 between California's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

back row — kWh usedfront row — $ cost
A weekday in June on TOU-DR-1 Coastal Baseline Region — the back row is how much you use each hour, the front row is what that hour costs. Both are colored by the price at that hour. $3.72 a day, and 6pm alone accounts for $0.39 of it — the same power at 12am would cost $0.18. Rows are scaled separately; kWh and dollars are not the same units.

Same usage, different plan

$419a year

That is the gap between the cheapest plan you could be on — TOU-DR-1 Coastal Baseline Region — and the priciest. Not by using less power. By being billed differently for the same power.

An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
