Why Is My Electric Bill So High? 10 Things to Check Before Spending More

Quick answer: a high bill does not prove you need solar

As of October 26, 2026, diagnose the bill before buying equipment. Compare billed days, average daily kWh, the rate plan, time-of-use periods, fixed and adjustment charges, and the same season last year.

If electricity use rose, trace the added load. If kWh stayed similar but dollars rose, inspect rates and charges. If neither explains the change, check actual or estimated meter reads, corrections, account balances and provider-specific bill details.

Normalize the comparison before deciding the bill increased

Write down the service start and end dates, number of billed days, total kWh and total new electric charges for the current bill and a comparable bill. A longer billing period can raise the total even when the home uses the same amount per day.

Calculate average daily kWh by dividing billed kWh by billed days. Compare with the same season last year when possible; comparing an unusually hot month with a mild month can misidentify weather-driven use as a permanent problem.

Separate energy use from the price and other charges

The amount due can change because the home used more kWh, the effective price changed, fixed charges changed, a credit disappeared, an adjustment posted, or a previous balance carried forward. Those are different causes and need different responses.

Do not divide the full amount due by kWh and call the result the electric rate if the bill includes taxes, fixed charges, gas, water, past-due amounts or other services. Reconcile the electric section line by line.

Check whether the meter read was actual or estimated

Utilities sometimes estimate usage when they cannot obtain a meter read. SCE explains that a later actual read can correct the earlier estimate, which can make a later statement look unusually high or low.

Record the prior and current meter status and any adjustment line. If the billed usage does not resemble the account's interval data or the physical meter, contact the utility rather than attempting to open or alter metering equipment.

Confirm the rate plan and every time-of-use window

On a time-of-use plan, identical kWh can cost different amounts depending on when the home uses electricity. Read the current bill or tariff for peak, off-peak, season, weekday and weekend rules; do not reuse hours from another utility or an older screenshot.

SCE and PG&E bill guides show usage and cost by rate period. LADWP also publishes separate residential rate structures. Test flexible loads such as EV charging, dishwashing or laundry against the home's actual plan before shifting them.

Identify fixed, minimum and adjustment charges

Some charges do not fall in direct proportion to kWh. Where shown on the account, list a Base Services Charge, minimum charge, taxes, public-purpose charges, late fees, corrections and credits separately from usage-based energy.

A new or changed fixed line can raise a low-usage bill even while the per-kWh portion falls. Compare the exact current rate documents and statement dates instead of relying on last year's label or a neighbor's bill.

Reconcile delivery, generation and any CCA

Some California bills separate delivery from generation. A community choice aggregator may provide generation while an investor-owned utility delivers electricity and presents the consolidated bill.

Count both sections once when comparing total electric supply costs. Confirm the service address, utility, generation provider and rate plan; a ZIP code alone does not establish who serves the home.

Trace the household loads most likely to change

Look for HVAC runtime during heat or cold, electric resistance heating, pool or spa schedules, water heating, dehumidification, refrigeration problems, EV charging, added occupants, construction equipment and new appliances. Estimate each load from rated watts, operating hours and measured behavior rather than guessing from the bill total.

A clogged HVAC filter can restrict airflow and increase runtime, while a failed thermostat, stuck pool schedule or malfunctioning appliance can operate longer than expected. Follow manufacturer instructions and use qualified service help for repairs.

Use interval data as a detective tool

Download hourly or sub-hourly interval data when the utility provides it. Mark overnight baseload, morning and evening peaks, weather-driven periods, EV sessions and any continuous step increase.

Compare the timing with thermostat history, charger logs, pool schedules and occupancy. Interval data can narrow the question, but it does not identify an appliance by itself; confirm with safe observation, equipment data or a qualified technician.

Run safe checks before calling for service

Verify thermostat schedules, replace or clean filters only as the equipment instructions allow, review pool and water-heater timers, and unplug nonessential plug loads one category at a time. A consumer plug-in energy monitor can help with compatible cord-connected devices.

Do not remove a utility meter, open energized panels, bypass safety devices or work on fixed wiring to diagnose a bill. For suspected electrical, HVAC, water-heating or appliance faults, use a properly qualified professional.

Use a home energy assessment for building-wide causes

DOE says a home energy assessment can show how a home uses energy and identify cost-effective efficiency measures. Depending on scope, an assessment can review the building envelope, insulation, air leakage, ducts, heating, cooling, water heating and major appliances.

Ask what testing is included, who performs it and whether the recommendations separate health and safety issues from optional upgrades. Do not treat a sales-only walk-through as an independent energy diagnosis.

Document a utility billing question clearly

Before contacting the utility, save the current bill, comparable bills, rate-plan name, interval export, meter-read status, screenshots and your calculation of billed days and average daily kWh. Write the exact line item or interval that does not reconcile.

Ask whether the reading was estimated, whether the bill spans more than one period, whether an adjustment or prior balance posted, and whether a discount or credit ended. Request a case number and retain written responses.

Check assistance and efficiency programs separately

For eligible California households, CPUC pages describe CARE and FERA bill discounts and Energy Savings Assistance weatherization or efficiency services. California's Department of Community Services and Development administers LIHEAP assistance through local providers.

LADWP has separate municipal assistance programs, including EZ-SAVE and LIHEAP information. Eligibility, funding and income limits can change, so use the current administrator page and do not assume enrollment from a ZIP code or an old threshold.

Solar is not a diagnosis for a high bill

Solar may reduce grid purchases for a suitable home, but solar is not a diagnosis for estimated reads, a longer billing period, an equipment fault, a past-due balance, an ineligible rate plan or a missing discount.

After identifying the bill's cause, compare solar using the home's load shape, utility tariff, roof, installed cash price, financing, export compensation and remaining charges. Keep that decision separate from urgent payment or repair needs.

Bottom line: keep a one-page bill investigation record

Record billed days, total and average daily kWh, rate plan, peak-period kWh, generation and delivery providers, fixed charges, meter status, adjustments, weather, major load changes and the outcome of any utility case.

That record turns a surprising total into testable questions. It also gives an auditor, technician or future solar reviewer evidence to work from instead of an unsupported savings promise.
