What each term is doing
kWh measures the electricity consumed.
Rate is the example price applied to usage.
Supply or usage charge reflects the consumption calculation.
Delivery represents an example infrastructure-related charge.
Customer charge is a recurring fixed amount.
Credit reduces the balance.
Utility Bill Terms People Commonly Confuse
| Terms | Difference |
|---|---|
| Billing address vs service address | The billing address receives correspondence. The service address is where the utility is supplied. |
| Statement date vs billing period | The statement date is when the bill was generated. The billing period is the range of service dates. |
| Meter reading vs usage | A meter reading is a recorded meter value. Usage is the consumption calculated or measured from meter information. |
| kW vs kWh | kW measures power. kWh measures electrical energy used over time. |
| Therm vs CCF | A therm measures energy content. CCF measures a volume of 100 cubic feet. |
| Supply vs delivery | Supply generally relates to the commodity or energy. Delivery generally relates to moving the service through infrastructure. |
| Fixed charge vs usage charge | A fixed charge does not directly depend on each unit consumed. A usage charge changes with consumption. |
| Actual vs estimated reading | An actual reading comes from meter data. An estimated reading is calculated when actual meter information is not used. |
| Payment vs credit | A payment is money received from the customer. A credit is any account reduction and can have several causes. |
| Rate schedule vs tariff | A rate schedule defines applicable prices and billing rules; a tariff can contain broader approved rates, terms and conditions. |
Utility Bill Abbreviations Quick Reference
Why Utility Bill Terms Vary by Provider
There is no single national vocabulary used on every electricity, gas, water or telecommunications statement.
Terminology can change because of:
- service type;
- state and local regulation;
- utility tariffs and rate schedules;
- competitive versus regulated energy markets;
- municipal versus investor-owned utility structures;
- local taxes and fees;
- provider billing systems;
- customer class and service plan.
If your bill contains an acronym, rider, tariff code or fee that does not appear in this glossary, search the issuing provider's current billing glossary, tariff or rate schedule rather than assuming a similar-looking abbreviation means the same thing.
Frequently Asked Questions
kWh means kilowatt-hour. It is a unit of electrical energy and commonly represents the amount of electricity consumed during the billing period.
CCF means one hundred cubic feet. Some natural-gas and water utilities use CCF as a volume measurement. On a water bill, 100 cubic feet is approximately 748 gallons.
A therm is an energy unit equal to 100,000 Btu. It measures energy content rather than simply gas volume.
TOU means time-of-use. Under a TOU rate, electricity prices can vary according to when electricity is consumed.
kW measures electrical power or demand. kWh measures electrical energy consumed over time.
It means the provider used an estimate of consumption instead of an actual meter reading for that billing period. The provider's estimation method can vary.
A customer charge is generally a recurring account or service charge that may apply separately from consumption-based charges. Similar charges can be called base, fixed or basic service charges by different providers.
A tariff is a formal set of utility rates, terms and service conditions under the applicable regulatory system. A specific customer's bill is normally calculated under a particular rate schedule or tariff provision.
Utilities often use local tariff codes, adjustment names and provider-specific abbreviations. The issuing utility's current bill glossary or rate documentation is the best source for a unique code.
