LADWP vs. SCE: A Homeowner's Guide to Southern California's Energy Providers

The two utilities couldn't be more different under the hood

If you live in Southern California, your power either comes from a giant investor-owned utility regulated by the state, or from a city-run department that answers to a board and the LA City Council. SCE is the first kind. LADWP is the second. That single distinction drives almost everything that matters to a solar-plus-battery owner: what you pay per kWh, when peak hits, and how much you get for the energy you send back.

Most comparisons stop at "LADWP is cheaper." It usually is. But cheaper rates change the math on a battery, and the rules for exporting solar are wildly different between the two. Here's how they actually stack up if you're trying to decide between plans, or you're moving across a service-area line and your old assumptions just got invalidated.

Rate structures compared

SCE pushes almost everyone toward time-of-use now. The plans you'll run into are TOU-D-4-9PM, TOU-D-5-8PM, and TOU-D-PRIME. The number in the name is the peak window, and that window is the whole game.

On TOU-D-4-9PM, the expensive hours are 4 to 9 p.m. on weekdays. In summer that on-peak price climbs into the high 50s to low 60s of cents per kWh, while off-peak sits closer to the high 20s (these are mid-2026 numbers, and every figure in this post drifts year to year, so treat them as ballpark and check your own bill). That's better than a 2x swing between the cheapest and most expensive electricity of the day. TOU-D-PRIME is the plan built for electrified homes: heat pump, EV, battery. It carries a monthly basic charge (around $16 last I checked) but flattens the off-peak rate further, so if you can dodge that 4–9 window almost entirely, PRIME tends to win.

LADWP is a different animal. Most residential customers are on R-1A, a tiered plan where price depends on how much you use, not when. Tiers reset seasonally and step up as you burn through monthly allotments. There's no peak window punishing you at 6 p.m. For time-of-use, LADWP offers R-1B as an option rather than shoving you onto it. R-1B's high-peak period runs roughly 1 to 5 p.m. on summer weekdays, with low-peak shoulders before and after. Note that window: 1 p.m., not 4 p.m. It lines up with solar production, which matters a lot for how you'd run a battery.

The headline number: LADWP's blended residential rates generally land well below SCE's. An SCE customer paying 40-something cents blended in summer might see an LADWP neighbor in the high 20s. That gap is real, and it's the reason battery payback periods look so different across the line.

Solar and battery programs

This is where being a municipal utility stops being a footnote and becomes the main story.

SCE operates under California's Net Billing Tariff, the thing everyone calls NEM 3.0. Since April 2023, new solar systems on SCE export to the grid at avoided-cost rates instead of the retail rate. In plain terms: the credit you get for a kWh you send back is often 75% lower than what you'd pay to buy that same kWh an hour later. Exporting at midday and buying back at 7 p.m. used to be close to a wash. Under NBT it's a losing trade. The export credits also swing hard by hour and season, with the best values landing on late-summer evenings, exactly when a battery can discharge.

LADWP isn't regulated by the CPUC, so NEM 3.0 doesn't apply. LADWP still runs its own net metering program at terms far closer to old-school retail net metering, plus its Solar Rooftops and incentive offerings (the current details live at ladwp.com/residential-services/solar-programs). For a new solar owner, that's a meaningful edge. Energy you overproduce at noon is worth roughly what you'd pay for it, so the penalty for not perfectly timing your own consumption is small.

Battery incentives are their own story, and people treat the SGIP rebate like free money sitting on the table. The details matter more than that. It's a CPUC program funded by ratepayer surcharges and administered through the IOUs and SoCalGas, which means your provider actually does affect whether you can get it: a LADWP electric customer with no SoCalGas gas service can fall outside the program entirely. And the budgets have tightened. As of mid-2026, the General Market, Equity, and Equity Resiliency buckets are closed to new applications, and the income-qualified RSSE pathway (under AB 209) is what's still taking them. So confirm the current status and your own eligibility before you count on any of it. Don't bake an SGIP rebate into your payback math until you know you actually qualify.

Which utility is better for solar owners?

It depends on what you already have, but the logic is clean once you separate the two cases.

If you have solar and no battery, LADWP is the friendlier place to be. Retail-style net metering means your daytime overproduction offsets your evening usage at nearly full value, and there's no 4–9 p.m. peak waiting to gouge you. You can be sloppy about timing and still come out fine.

If you're on SCE, a battery isn't a nice-to-have. It's most of the value. Under NBT, the move is to stop exporting at the bad rate and instead store your midday solar, then discharge it during that 4–9 p.m. peak so you're not buying 60-cent electricity. The battery's job shifts from "backup" to "daily arbitrage engine." Sized and scheduled right, it recovers the value NEM 3.0 took away. Sized wrong or left on a dumb schedule, it leaves real money in SCE's pocket every evening.

So the better-for-solar answer flips depending on hardware. LADWP rewards solar alone. SCE punishes solar alone and rewards solar-plus-battery that's actually managed.

There's a catch worth naming: LADWP's lower rates mean a smaller price spread to arbitrage, so a battery there pays back more slowly even though the export rules are kinder. SCE's brutal export rules and steep peak create a bigger spread, which is precisely what makes a well-run battery so valuable on that side of the line.

How Grid Getter optimizes for both

The two utilities need opposite battery strategies, and that's the part homeowners get wrong. A schedule that's correct on SCE is leaving value on the table on LADWP, and vice versa.

On SCE, Grid Getter builds your Powerwall automation around the 4–9 p.m. peak. It charges from solar through the day, holds that charge instead of dumping it to the grid at NBT rates, and discharges into the peak window so your house rides through dinner without pulling expensive grid power. The same logic adapts to whichever SCE plan you're on, because the peak window is encoded in your rate, not guessed at.

On LADWP, the strategy changes. With retail-style net metering and no harsh evening peak, aggressive peak-discharge matters less, and self-consumption plus backup reserve takes priority. If you're on R-1B with that 1–5 p.m. high-peak, Grid Getter shifts the discharge earlier to match the actual window rather than blindly copying an SCE schedule.

The point is that your automation should know which utility and which rate plan you're on and behave accordingly. Grid Getter pulls your specific plan and peak windows into the schedule so the Powerwall does the right thing without you re-tuning it every season. If you want to see what that looks like for your address and rate, you can set it up free and check the numbers before committing to anything.

Start with your bill

Pull up your most recent statement and find two things: your rate plan code (it's printed near the top, something like TOU-D-PRIME or R-1A) and your summer on-peak price per kWh. Then find what you're credited per kWh for exports. If you're on SCE and that export credit is a fraction of your peak rate, a battery on a peak-discharge schedule is where your savings are hiding. If you're on LADWP, check whether you're on R-1A or R-1B before assuming time-of-use even applies to you. Plenty of people are paying for battery schedules that their tiered plan doesn't reward.
