The short answer
Your Southern California electric bill splits into generation (the energy itself), delivery (moving it to your home), and taxes and fees. Time-of-use rates mean the same kilowatt-hour costs more in the 4–9 PM peak. Reading your usage and rate plan tells you how much you'd actually offset with solar — and under NEM 3.0, why a battery matters.

Why your bill feels like a mystery
Between generation charges, delivery fees, and time-of-use rates, a Southern California electric bill is genuinely hard to read. But learning the layout pays off: it shows where your money actually goes, reveals how much you could offset with solar, and helps you pick the right rate plan. The basics are similar whether you're with Southern California Edison (SCE), San Diego Gas & Electric (SDG&E), or the Los Angeles Department of Water and Power (LADWP).
Start with the account summary
The summary at the top shows your total amount due, due date, previous balance, and new charges for the period. SCE breaks out the new charges and may show a twice-yearly California Climate Credit. SDG&E lists electric delivery, gas, and community energy generation separately, then combines them into one payment. LADWP rolls electricity, water, and sanitation into a single statement with a subtotal per service — so look for the electricity line specifically.
Read your usage: kilowatt-hours and when you use them
Your usage chart shows how many kilowatt-hours (kWh) you used and, increasingly, when. SCE shows a 12-month chart with your daily average; SDG&E and LADWP show similar graphs. Two numbers matter most for solar: your total annual kWh (how big a system you'd need) and your peak-hour usage (how much a battery would help). This is the data we use to size a system on your free estimate.
Generation vs. delivery charges
Most of the confusion lives here. Generation is the cost of the electricity itself; delivery is what the utility charges to carry it over poles and wires to your home, plus various fees. Solar reduces the energy you pull from the grid, which cuts both — but you'll still see fixed charges and minimum-bill amounts even after going solar. That's normal, and it's why solar lowers a bill rather than zeroing it.
Time-of-use rates: when matters as much as how much
Nearly all SoCal solar customers are on a time-of-use (TOU) plan, where the same kWh costs more during the 4–9 PM peak and less off-peak. Matching your usage — and your stored solar — to those windows is where real savings live. We break this down in understanding time-of-use rates.
How solar changes your bill under NEM 3.0
Once solar is installed, your bill nets the energy you pulled from the grid against what you exported. Under NEM 3.0, utilities pay much less for exported solar than they charge you in the evening — so the winning move is to store your daytime solar in a battery and use it during peak hours instead of exporting it cheaply. That's why a battery is now standard on new installs; see our battery storage page for how the pairing works.
FAQ
Generation is the cost of the electricity itself. Delivery is what the utility charges to transport it to your home over its poles and wires, plus fixed fees. Solar reduces the grid energy you use, lowering both — but fixed charges and minimum bills remain, which is why solar lowers your bill rather than eliminating it.
