To understand a California electricity bill, identify the delivery utility, generation provider and rate-plan code first. Then separate the prices that depend on usage from fixed charges, minimum-bill rules, adjustments and credits. This makes it easier to explain a change or compare an eligible alternative.
Reviewed October 21, 2026: This is a guide to bill structure. It does not quote a statewide current household rate, and its review date does not reverify every tariff in the calculators.
Delivery utility and generation provider
PG&E, SCE and SDG&E are California’s large investor-owned electric utilities. California also has publicly owned utilities, including LADWP and SMUD, with their own rate schedules. Confirm the provider at your service address rather than applying a nearby utility’s rate.
For CCA customers, the delivery utility and generation provider are separate. Read both sections of the bill. The CPUC’s CCA FAQ explains this arrangement; the retail choice overview describes PCIA.
Usage prices: TOU, tiers and baseline
On a TOU plan, prices vary by the time and sometimes the season or day of use. Tiered plans depend on usage within defined blocks. Some tariffs combine time-based prices with a baseline allowance or credit. Use the exact tariff’s rules rather than assuming every plan has the same peak window.
A baseline allowance depends on the applicable location and household conditions; it is not a universal monthly kWh amount. Check the utility’s current baseline and discount eligibility. A plan’s listed price for one period does not describe its whole-bill cost.
Fixed charges and minimum bills
A fixed charge is charged under the tariff independently of the amount of energy consumed. A minimum bill sets a floor under specified billing components. They are different mechanisms, and a tariff may change how they interact. Review the current plan before adding either to an estimate.
The CPUC’s electric rates guide describes the Base Services Charge and explains the costs recovered in electric rates. Read the utility’s implementation and your bill to determine the applicable amount and discount treatment. A separate fixed charge can accompany lower usage prices; compare the combined result.
Generation, adjustments, taxes and credits
Check whether the energy rate already includes utility generation or represents delivery only. Add the applicable generation price once. Identify adjustments such as PCIA, local taxes, program discounts and periodic credits, and record what an estimate includes. For solar, imports and exports may be priced under separate rules; check the applicable tariff and generation-provider terms.
For an effective average cost, divide the total for a stated bill period by the kWh used in that period. This is a description of that bill, not necessarily the price of the next kWh or a forecast for another season.
Prepare a useful rate comparison
- Recent bill: utility, plan, generation provider, discount and solar status
- Usage: monthly or interval data and the dates covered
- Sources: tariff effective date, source check date and any later rate change
- Model: included charges, assumptions, eligibility and omitted items
Start with California Rate Finder or Compare Plans. These tools focus on supported PG&E, SCE and SDG&E datasets; municipal utilities and unconfirmed CCA plans need their own sources. Use the official PG&E, SCE, SDG&E or LADWP rate documents to confirm your terms.
