How to Read Your Electric Bill
Consumer-source review frozen August 29, 2026 · EIA price context through June 2026 · Updated August 29, 2026
Most electric bills combine charges for the energy itself, for delivering it, and a set of fixed charges, riders, taxes and credits, grouped differently by every utility. The fastest way to know which parts you can shop for is to check with your utility or state commission; the bill gives strong clues but not proof.
Bill anatomy: illustrative, not universal
Con Edison's consumer guide is one regulated utility's example: it groups a bill into supply, delivery and taxes. Other utilities group the same kinds of charges differently, and one bill's “delivery” can contain items another bill prints as riders.
| Line-item family | What the cited example supports | Where to look |
|---|---|---|
| Supply or generation | Con Edison says this is the power supplied for the customer; its customers may buy that supply from Con Edison or an energy service company. | A supply, generation or energy-charge section; a supplier name may appear nearby. |
| Delivery or distribution | Con Edison describes delivery as the infrastructure and operations used to deliver energy. | A delivery or distribution section. It may contain both usage-based and separately labeled items. |
| Taxes | Con Edison notes that some taxes appear as lines and some infrastructure taxes are embedded in its delivery charge. | The taxes and fees area, plus notes describing amounts embedded elsewhere. |
| Fixed customer charge | A flat labeled charge can sit beside the usage-based lines. The Energy Factbook rate-case ledger links docket filings that show how utilities seek approval for fixed charges. | Look for “customer,” “basic service” or another fixed-charge label. |
| Riders | Riders recover docket-specific costs. See the filing-linked examples in the Energy Factbook rate-case ledger. | Short named or abbreviated lines, often near delivery charges. |
Bills can also carry credits and adjustments; formats vary.
Quoted energy price versus effective rate
The effective rate for one current billing period is total current-period electricity charges divided by billed kWh. It is broader than a quoted supply price because signed delivery, fixed, rider, tax and credit amounts remain in the numerator.
Hypothetical sample bill
These values are invented to demonstrate the arithmetic, not measured prices:
| Energy charge: 800 kWh at 10.0¢/kWh | +$80.00 |
| Delivery charge | +$48.00 |
| Fixed customer charge | +$12.00 |
| Rider A | +$6.00 |
| Rider B | +$4.00 |
| Tax | +$7.00 |
| Credit | −$5.00 |
| Current-period electricity charges | $152.00 |
$152.00 ÷ 800 kWh = 19.0¢/kWh effective rate. That exceeds the hypothetical 10.0¢/kWh quoted energy charge because the example includes the other signed components.
For context only, the June 2026 national residential average was 18.34¢/kWh. EIA calculates that average as revenue divided by sales, so it is itself an effective price and cannot serve as the “quoted energy price” in this comparison.
What clues say you may be able to shop?
A named third-party supplier line or a supplier-choice notice is strong evidence that supply is shoppable. A bundled bill is not proof that the customer is ineligible: someone who may choose but never switched may still see only the incumbent utility.
EIA's customer-choice FAQ directs customers to confirm the option and available suppliers with the distribution utility or the state utility commission. Regardless of supplier, EIA says the distribution utility delivers the electricity and charges for delivery.
In its March 15, 2023 review, EIA counted 13 states and the District of Columbia with active statewide or districtwide residential retail-choice programs. That dated count excluded Texas because choice is mandatory under state law in areas managed by ERCOT. It is context, not a current state list.
Billing-period length
Compare the service-start and service-end dates, not just the month printed at the top. More billed days can raise kWh even if daily use is unchanged. Enter both period lengths in the bill-change checker to compare kWh per day.
Estimated versus actual meter reads
Look for “actual,” “estimated” or a meter-read code beside the beginning and ending readings. The legal details vary. As one commission-regulated example, 52 Pa. Code § 56.12 generally calls for actual readings but permits specified estimates, including every other month for monthly billing when the customer may report a reading. The rule also addresses later corrections when an actual read establishes an error. This Pennsylvania example is not a nationwide rule.
Renters, submeters and allocated master bills
A renter may receive electricity through a building owner instead of a utility account in the renter's name. Texas's submetering rule defines submetering as individual dwelling-unit metering performed by the owner and prescribes what its tenant bill must show. Texas's master-meter rule covers non-submetered service and allows specified allocation methods. A ratio utility billing system, often shortened to RUBS, is a label used for this allocation approach rather than a reading from the unit's own utility meter.
An allocated bill can combine the master bill, central-system costs, taxes and the building's approved allocation method. Dividing that allocated amount by a unit's own kWh, if the unit even has a separate reading, can therefore exceed the utility tariff's quoted energy rate. The cited Texas rules illustrate one jurisdiction; check the lease, bill, utility and state or local regulator for the rules that apply. This is consumer information, not legal advice.

Frequently asked questions
Can a bill prove that I may choose an electricity supplier?
No. A named third-party supplier or choice notice is a strong clue, but a bundled bill is not proof that choice is unavailable. EIA says to confirm with the distribution utility or state utility commission.
Why can my effective rate exceed the advertised energy price?
The advertised energy price may cover supply only. The effective rate divides current-period total electricity charges, including delivery and other signed line items, by billed kWh.
What should a renter check when electricity comes through the landlord?
Ask whether the unit is individually submetered or the building's master bill is allocated. Texas's submetering rule and master-meter allocation rule illustrate how a commission can regulate the two arrangements; rules vary by jurisdiction.
