The honest math on LA home energy.
LADWP's rates don't work like anyone else's in California — most advice you'll find online is written for SCE or PG&E and is simply wrong here. We do the arithmetic on real LADWP bills and tell you straight what pays back, what doesn't, and what your electricity actually costs.

Read the math →LADWP's default rate charges by how much you use; the optional TOU rate charges by when. Here's who wins on each — with the marginal-rate math most comparisons skip.
Read the math →Real numbers from a real LADWP home with two Teslas: cost per mile, cost per year, why the "expensive Wall Connector" myth is wrong, and when LADWP's TOU rate is worth it.
Read the math →LADWP still runs retail-rate net metering — not NEM 3.0. Here's exactly how the credits work, why batteries don't pay back in LA, why panels do, and how to size a system.
Read the math →Real bills, not brochures. Every rate on this site is read off actual LADWP residential bills and re-verified against LADWP's published schedules — our bill model reproduces a real 1,845 kWh bill to within 38 cents.
Real hardware, not affiliate copy. Our test home runs a 7.6 kW rooftop solar system (59 MWh generated and counting) and has charged two Teslas on LADWP power since 2022. When we say what a battery saves, it's because we did the math on our own quotes — and turned them down.
We'll tell you not to buy. The most-read page on this site concludes that a $14,485 Powerwall will never pay for itself in LA. If the math says don't, we say don't.
