Home charging is the main financial reason to own an electric car in Los Angeles. It is also the part most owners never optimise, because the default is simply to plug in and stop thinking about it.
The single largest variable is not how much you charge. It is when.
Why timing dominates
Electricity does not cost the same amount all day. Demand on the grid peaks in the late afternoon and evening, when air conditioning is running and people arrive home. Overnight, demand collapses.
Time-of-use pricing reflects that. Rather than one flat rate, you pay more during peak periods and less during off-peak ones.
Which is unusually good news for EV owners, because almost nobody needs to charge during peak hours. Your car sits on the driveway all night doing nothing. If it draws its power between midnight and six rather than between five and eleven, you get the same full battery in the morning at a materially lower cost.
This is the rare efficiency measure that asks nothing of you. You are not being asked to be less comfortable or to wait longer. You are being asked to change a setting.
How LADWP structures it
LADWP offers residential customers an opt-in time-of-use plan as an alternative to the standard tiered rate. On a tiered rate you pay more per unit as your total monthly consumption rises. On time-of-use there are no tiers — price varies by period instead.
That distinction matters for EV owners specifically. Charging adds real consumption to a household total, and on a tiered plan that extra consumption can push your whole home into a more expensive tier. On time-of-use, the charging is simply priced by when it happens.
There is also a second route worth understanding.
The separate EV meter
LADWP offers a discount on charging that is separately metered and on a time-of-use rate. In practice this means installing a second meter that measures only your charging circuit.
The advantages:
- Your charging is billed independently, so it cannot drag the rest of your household consumption into a higher tier.
- It qualifies for LADWP’s EV charging discount.
- LADWP has offered a rebate toward installing the meter itself, offsetting part of the setup cost.
The trade-off is the up-front work — a second meter is a real installation, not a settings change. Whether it pays back depends on how much you drive. For a household putting serious annual mileage on one or two electric vehicles, it tends to make sense. For someone charging a plug-in hybrid twice a week, it usually does not.
Working out your own number
You do not need a spreadsheet. Three figures:
- Monthly miles.
- Your car’s consumption — most electric vehicles land between 0.25 and 0.35 kilowatt-hours per mile. Larger SUVs and trucks sit at the upper end or beyond.
- Your rate for the period you actually charge in.
So a thousand miles a month at 0.3 kWh per mile is about 300 kilowatt-hours. Multiply by your off-peak rate to get your monthly charging cost.
For context, 300 kilowatt-hours is roughly the consumption of an additional refrigerator plus a reasonable amount of extra load — noticeable on a bill, but not the transformation people often expect.
Do the same calculation at your peak rate and the gap between the two numbers is what charging at the right time is worth to you each month. For most households it is the difference between an unremarkable line on the bill and one you notice.
Rebates worth claiming
LADWP has run its Charge Up LA programme for residential customers, covering:
- A rebate toward the purchase and installation of a qualifying Level 2 charger
- A further rebate toward installing a dedicated EV meter
- An additional amount for customers on the Lifeline or EZ-SAVE assistance programmes
Two conditions catch people out. First, the charger and meter generally need to be hardwired and installed by a licensed electrician for installation costs to be claimable. Second, the charger has to be on the qualifying product list — not every unit sold online is.
Rebate amounts, eligibility rules and rate schedules change, sometimes mid-year. We deliberately do not publish current figures here, because a page with last year’s numbers is worse than no numbers at all. Check LADWP’s current terms, or ask us and we will confirm what applies to your address before you commit to anything.
Home versus public charging
Worth stating plainly, because it is the underlying economics of the whole decision: home charging is substantially cheaper than public DC fast charging in nearly every case.
Fast charging carries a premium for the speed and for the infrastructure behind it. It is genuinely useful on a road trip and a poor way to fuel a car day to day. If most of your charging happens away from home at commercial rates, the financial case for owning the vehicle weakens considerably — which is precisely why a home charger is usually the first thing an EV owner should sort out.
What we would actually do
If you are charging at home in Los Angeles:
- Move to a time-of-use rate and set your car or charger to start after the peak period ends. This is free and it is the biggest single lever.
- Use the car’s scheduling, not a timer switch. Every modern EV can be told when to start charging, and many chargers can too. There is no need to add hardware.
- Run the separate-meter numbers if you are a high-mileage household or run two electric vehicles. It is real work up front, and it pays back proportionally to how much you drive.
- Claim the rebate — and check the hardwiring and licensed-installer conditions before the work happens rather than after.
- Charge to 80 percent day to day unless you need the full range. Better for the battery, and it shifts less energy at whatever rate you are on.
One thing worth not economising on
Everything above is about reducing what you pay per kilowatt-hour. None of it is a reason to economise on the installation itself.
An EV charger draws near its maximum current for hours at a time, and an undersized or poorly terminated circuit fails slowly and invisibly — there are manufacturer recalls specifically about home wiring overheating. Saving a few hundred dollars on the install is a poor trade against that, and it will not show up on your bill either way.
Frequently Asked Questions
Does it cost less to charge an electric car at night in Los Angeles?
On a time-of-use rate, yes, and the difference is significant. These rates charge more during afternoon and evening peak periods and less overnight. Since almost everyone charges while asleep anyway, moving to a time-of-use plan often costs nothing in convenience.
What is a separate EV meter and is it worth installing?
It is a second meter that measures only your charging circuit, letting that consumption be billed separately from the rest of the house. LADWP offers a discount for charging on a separately metered time-of-use account, plus a rebate toward installing the meter itself.
How do I work out what charging actually costs me per month?
Multiply your monthly miles by your car's consumption, usually around 0.25 to 0.35 kilowatt-hours per mile, then multiply by your rate. A thousand miles a month at 0.3 works out near 300 kilowatt-hours, which is roughly comparable to adding a second refrigerator plus some.
Is home charging cheaper than public fast charging?
Substantially, in almost every case. Public DC fast charging carries a premium for the speed and the infrastructure behind it. Home charging on an off-peak rate is typically the cheapest way to fuel an electric vehicle, which is the main financial argument for installing one.
What rebates does LADWP offer for home EV charging?
LADWP has run its Charge Up LA programme covering a rebate toward a qualifying Level 2 charger, a further rebate toward a dedicated EV meter, and an additional amount for customers on its Lifeline or EZ-SAVE assistance programmes. Amounts and eligibility change, so confirm current terms.
Do I need a licensed electrician to qualify for LADWP rebates?
To claim installation costs under the programme, the charger and EV meter must be hardwired and installed by a licensed electrician. This is worth knowing before a do-it-yourself attempt, because the labour portion of the rebate typically disappears without it.
Will charging an EV push me into a higher billing tier?
On a tiered rate it can, because charging adds meaningful consumption to your household total. That is one reason a time-of-use plan or a separate EV meter often works out better, since the charging load is priced by time rather than by pushing your whole home into a higher tier.
