Glossary & Terms

BCF – Billion cubic feet.

Billing Period Delivery Quantity – sum of Customer’s Daily Delivery Quantities between meter reading dates, less Company Shrinkage.

BTU or British Thermal Unit - the amount of heat required to raise the temperature of one (1) pound of water one degree Fahrenheit (1º F.) at sixty degrees Fahrenheit (60º F.).

CCF - one hundred (100) cubic feet of gas.

Citygate – Physical connection of facilities between Company and Florida Gas Transmission Company.

Cubic Foot – The most common unit of measurement of gas volume. The amount of gas required to fill a volume of one cubic feet under standard conditions of temperature, pressure and water vapor, usually referenced to 14.7 PSI and 60 degrees Fahrenheit. Very roughly, one cubic foot equals one thousand Btu’s (1 Cf = 1 Mbtu).

Daily Delivery Quantity – daily amount of natural gas, in Therms, elected by Customer to be delivered for their account.

Day - a period of twenty-four (24) consecutive hours beginning and ending at 10:00 A.M. Eastern Clock Time.

Dekatherm (Dth) – A unit of heating value equal to 10 Therms or one million Btu’s (1 Mmbtu). Very roughly, 1 Mcf = 1 Mmbtu = 1 Dth (or dt).

FERC – Federal Energy Regulatory Commission

FGT – Florida Gas Transmission Company

Firm Recallable Capacity – The highest quality sales or transmission service offered to customers under a filed rate scheduled that anticipates no planned interruption. Firm service is usually associated with distribution companies that serve residential customers and other "high priority end-users," but can also apply to upstream pipelines and other customers.

MCF - one thousand (1,000) cubic feet of gas.

Mmbtu – One million British Thermal Units determined on the basis of gross heating value, with gross heating value determined by sixty degrees Fahrenheit when saturated with water vapor at an absolute pressure of fourteen and seventy-three hundredths (14.73) psia, adjusted for water content as delivered. (The letter M denotes a thousand. Two M’s represents a thousand thousand, or one million.) Generally accepted as a rough equivalent of an Mcf.

MMcf – One million cubic feet.

Month - the period between and two (2) regular readings of Company’s meters at approximately thirty (30) day intervals.

Natural Gas or Gas – Natural Gas produced from Gas swells and Gas produced in association with oil (casinghead Gas) and/or the residue Gas resulting from processing both casinghead Gas and Gas-well Gas.

Pool Manager - any Person who has been engaged by one or more Customer(s) to be responsible for the delivery of natural gas to the Company’s Citygate(s) for such Customer(s).

Public Utility (Service) Commission – State commissions that regulate the activities of intrastate pipelines and local distribution companies (LDC’s), as well as electric, telephone and water utilities.

Tariff – Compilation of all the effective rate schedules for a company, along with general terms and conditions of service.

Therm - one hundred thousand (100,000) British Thermal Units.

Total Heating Value - the number of British Thermal Units produced by combustion in a recording calorimeter at a constant pressure of the amount of gas which would occupy a volume of one (1) cubic foot at a temperature of sixty degrees Fahrenheit (60º F.) if saturated with water vapor, and under a pressure equal to that of thirty inches (30") of mercury at thirty-two degrees Fahrenheit (32º F.) and under standard gravitational force (acceleration 980.665 centimeters per second per second) with air of the same temperature and pressure as the gas, when the products of combustion are cooled to the initial temperature of the gas and air, and when the water formed by combustion is condensed to the liquid state.

Company will determine a monthly average heating value of natural gas to be effective as of the first day of each month. Said monthly average heating value will be in effect on a calendar month basis. It will reflect the average monthly heating value of the natural gas delivered to Company by its pipeline supplier during the next immediately preceding calendar month.

Working Day – the days Monday through Friday, exclusive of Company Holidays, unless notified otherwise.

Year - a period of three hundred sixty-five (365) consecutive days except that in a year having a date of February twenty-nine (29) such year shall consist of three hundred sixty-six (366) consecutive days.
