What does EV-TOU 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 | $207 | $2,483 | 51.0¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $410 | $4,920 | 52.0¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $502 | $6,028 | 46.0¢ / 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.

Should you be on EV-TOU?
This is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 85.3¢ a kWh; at the best hour, 30.8¢ — 2.8× apart for identical electricity.
That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 4pm to midnight is about $199 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.
Expect the bill to move with the calendar. The same family home costs about $631 in July and $279 in February — a $351 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.
How it compares to San Diego Gas & Electric’s other plans
Measured against the other residential plans this utility files, a family home lands 4th cheapest of 4. The cheapest option, EV-TOU-5, would run about $661 a year less.

Who can be on San Diego Gas & Electric’s EV-TOU?
Eligibility is not our judgement — it is written into the tariff San Diego Gas & Electric filed. This is what that document says:
Optionally available to domestic service for charging of a currently registered Motor Vehicle, as defined by the California Motor Vehicle Code, which is: 1) a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV) recharged via a recharging outlet at the customer’s premises; or, 2) a natural gas vehicle (NGV) refueled via a home refueling appliance (HRA) at the customer’s premises. This schedule is not available to customers with a conventional charge sustaining (battery recharged solely from the vehicle’s on-board generator) hybrid electric vehicle (HEV). Pursuant to decision D.18-01-024, applicable to customers who pass through the rates to drivers charging their personal light-duty vehicle at publicly available Electric Vehicle Supply Equipment (EVSE). separately metered

If this is new to you
- When is electricity cheapest? Off-peak hours explained
Overnight, usually. All weekend, often. The exact hours are in your tariff, not in a rule of thumb.
- 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.
- When should you charge an electric car at home?
The single biggest load most homes can move, and the easiest to automate.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
