Understanding Your Electric and Gas Bill (pdf)

Your Electric and Natural Gas Bill –

Understanding your electric and gas bill can provide answers to many questions about your service. Each month you will receive a bill for the service used during the past billing period. Billing periods are as close to 30 days as possible. Bills are based upon meter readings or estimated energy usage. Bills are calculated according to rates approved by state regulatory authorities.

How does Cheyenne Light measure your usage?

Measuring your electricity usage is done by kilowatt-hours (kWh). A kWh is the basic unit of electric energy equal to one kilowatt for one hour. A kilowatt-hour is 1,000 watts used for one hour. For example, if you have ten 100-Watt light bulbs on at one time, the demand is 1,000 Watts or 1 kilowatt (kW). If they remain on for one hour, the energy used is one kilowatt-hour (kWh).

Measuring your gas usage is done by cubic foot (cf). One cubic foot is equal to the amount of gas required to fill one cubic foot under standard temperature and pressure (60 degrees Fahrenheit and 14.7 pounds per square inch pressure). A CHEYENNE LIGHT meter reader visits each customer’s meter monthly and records the reading in thousand cubic feet (mcf). Since the energy content of a Mcf of natural gas varies throughout our service area, we convert the volume of gas you use to energy units called "decatherms" (a decatherm, or dth, equals one million British thermal units of energy). By doing this, we ensure you are billed for the amount of energy you used based on the energy content of natural gas for your locality. You pay neither more nor less than your fair share.

Your Cheyenne Light representative can provide additional information. The location and telephone number are shown on your bill and in the phone book. Good service is important, and we encourage you to contact us whenever you need information about your bill or services.

Your Rate Code is listed on the front of the bill. If you should have any questions about the rate you are being billed under, please contact your Cheyenne Light customer service office.
