Glossary of Terms Used by Utilities and Their Regulators
The following are entries for a selected glossary of terms used in the regulation and operation of utilities. It is not intended to be all-inclusive, but rather as an introduction in plain language to the meaning of some otherwise arcane sets of initials and combinations of words. They are grouped under headings indicating the context in which they usually are used.
D. Utility Finance

The sum of two or more demands which occur in the same time interval.
Combustible gas indicator (CGI)
A portable instrument used in leak detection to determine accurately the methane content in a given area.
The cost per unit volume of gas actually delivered to the buyer. The commodity charge is basically made up of the field purchase cost, the transmission costs that depend on the amount of gas transported, and a portion of the fixed costs of the transmission company.

A machine which draws in air or other gas, compresses it, and discharges it at a higher pressure. A jet engine is one form used in upgrading pressures for the transmission of gas. Truck mounted compressors are used in the distribution industry to operate equipment such as "jack hammers."
Any permanent combination of facilities which supplies the energy to move gas in transmission lines or into storage fields.
The liquid resulting when a vapor is subjected to cooling and/or pressure reduction.
The combining of the quantities of gas from two or more meters into a single quantity for the purpose of billing as if the usages were from a single meter. Sometimes referred to as combined billing.

Cushion (base) gas
The total volume of gas which will maintain storage reservoir pressure sufficient to deliver gas back into transmission systems. The volume of cushion gas is generally constant and its value is treated as part of a utility's rate base.
The volume of gas which a well, production field, pipeline or distribution system can deliver in a given period of time.

Federal Energy Regulatory Commission (FERC)
Federal agency which regulates the rates and service of interstate suppliers of electricity, and natural gas and oil transmission pipelines.
FERC rate design
Applies to pipelines which generally serve under a demand-commodity type rate structure. All variable costs, basically the purchased gas and compressor (pumping) fuel are included in the commodity portion of the rate. Fixed costs, such as wages, taxes, depreciation, are split between demand and commodity. Four basic forms of rate design used are:
Seaboard-Traditional rate design
50% of fixed cost in demand and 50% in commodity. Adopted to give recognition that a pipeline serves both peak and annual usages.
Rate design used in the 1940s for interstate pipelines and superseded by Seaboard. It places all fixed costs in demand. The commodity portion of the rate only contains a system's variable costs. The rationale behind this design is that the pipeline is sized (designed) to meet the systems peak load.
Places a pipeline's equity in the commodity portion of the rate, generally in the 25% to 35% range, and the remainder in demand. The purpose of this design is to unload cost from the commodity portion of the rate to make interruptible sales competitive with oil.
United-Opposite approach of modified fixed-variable
25% fixed cost in demand and 75% in commodity. Adopted during curtailment years to discourage sales to industry (i.e., interruptible rates based upon the commodity cost of gas). This design lost favor in the current price competitive gas market.
The raw material supplied to a processing plant for the chemical transformation to an intermediate or end product. Two examples of feedstocks are natural gas which is used for the production of fertilizers and plastics, and Naptha which is used for the production of synthetic natural gas (SNG).
Gas discarded after the heating value has been substantially spent, to the flue, stack or chimney. Improper ventilation can lead to asphyxiation.
An unexpected major occurrence which alters the application of the terms of a contract; sometimes referred to as "an act of God."
Occurs at a production well when decreases in temperature cause non-hydrocarbon components in the gas stream, such as water, to freeze and inhibit or block the normal flow of gas. The temperature drop is usually a result of either a decrease in pressure caused by rapid gas expansion, such as opening up a well to increase flow rates, and falling atmospheric temperatures.
An electrochemical device to convert chemical energy directly into electricity. It is similar in some respects to a storage battery or a dry cell. Like a battery, the fuel cell produces electricity by a chemical reaction. Unlike a storage battery, the fuel cell continues to produce electricity as long as fuel is added. In this respect, a fuel cell operates like an engine.
Natural gas, flammable gas, or other gas which is toxic or corrosive.
A layer of gas that rests above oil in an underground porous structure, or reservoir.
Gas casinghead (wet natural gas)
Associated and dissolved gas produced along with crude oil from oil wells. Sometimes called oil well gas or solution gas.
Gas cost adjustment (GCA)
A method of reflecting changes from month to month in the cost to a utility of gas supplied to customers. Elements in the calculation include changes in the price and quantities of gas from various pipeline suppliers, refunds ordered by FERC, and any reconciliation between GCA revenues and the actual payments utilities made for gas in the prior year.
Gas detector surveys
Are a type of leakage survey conducted by sampling with a gas detector instrument which has, as a minimum, a sensitivity equal to that of a combustible gas indicator (CGI).
A gas pipeline that transports gas from a production facility to a transmission line or main.
An amendment to the Natural Gas Act which exempts a distribution company from FERC regulations on the transportation and sale for resale of interstate natural gas received within the boundaries of a state, provided (1) all such gas is ultimately consumed within the state, and (2) the facilities and rates are regulated by the state.
Indefinite price escalator clause
A clause in contracts with producers which ties the price to be paid for natural gas to some other commodity, generally oil. The unknown quantification of the movement in price leads to the term "indefinite."
Gas sold to the electric or steam departments in a combination utility for use as fuel in steam or electric production.
Customers are served by pipelines which cross state borders and sales are subject to FERC jurisdiction.
Customer supply is produced and transported through a pipeline system which does not leave the state. Sales in the intrastate market are not regulated by the FERC.
Inventory of gas in a pipeline, or in a gas distribution system. By increasing the pressure in a pipeline a utility can store natural gas in order to meet a peak demand of short duration.
Liquefied Natural Gas (LNG)
Natural gas cooled to 259 F forms a liquid at atmospheric pressure. As natural gas liquefies, the volume is reduced 600 times, making both storage and long distance transportation economically feasible.
A given send out of gas which remains fairly constant over a period of time. Base load demands are not used in calculating space heating requirements since they do not vary with changes in temperature.
Load duration curve
A graph made by plotting load data, in descending order of magnitude, against time to determine the economics of alternative supplies to meet various levels of requirements.
A geographic area classified according to its approximate population density and its other characteristics that are considered when prescribing types of construction and methods of testing pipelines to be located in the area.

Lower explosive limit (LEL)
The minimum concentration of natural gas in air which forms an explosive mixture.
Market out clause
Permits a party to escape from the terms of a gas purchase contract upon certain conditions such as the contract price renders it unmarketable. This is generally an economic type escape clause and should not be confused with the force majeure clause.
Maximum allowable operating pressure (MAOP)
The maximum pressure at which a gas system may be operated in accordance with the rules and regulations of the State's gas safety code.
A colorless, odorless and flammable hydrocarbon gas. It is the major component of natural gas, making up roughly 85-90% of natural gas by volume.

the unit rate charged for each unit of gas actually purchased under a contract.
a fixed charge per unit of reserved capacity, levied each month, based on the contract or maximum demand of a customer, regardless of the volume of gas actually delivered. Most distribution utilities purchase gas from pipelines under parted rates, with demand as one part based on the requirement on the highest day of the year. Demand rates are not used by New York State gas distribution companies.

Interruptions and resumptions are generally automatically controlled by temperature sensitive switching equipment.
the charging for gas service on the basis of energy delivered (Btu's) as compared to volumetric rates (Ccf's). With therm rates, gas deliveries metered volumetrically are converted to therms for billing purposes on the basis of the heat content. Therm rates may be used in conjunction with other rate forms, e.g., flat rates or block rates.
Geographic sections of a utility or pipeline service area in which different rate levels exist due to cost-of-service differences, such as the distance from supply source on long pipelines or the heat content of the product.

Multiple thermal rate zones may be established within a service territory which receive gas from different supply sources with various heat contents to ensure equitable rate treatment for customers.
Types of Natural Gas Service
the delivery of gas to a customer, not subject to interruption. This service generally is the highest priority and provided at a higher cost. Residential and smaller commercial and industrial customers are usually firm service customers.
the delivery of gas to a customer, subject to interruption of service at the discretion of the utility, generally because of system supply or capacity limitations. Interruption may be manually controlled by the utility and/or automatic, based on outside temperatures.

the placement of distribution-owned gas in underground storage facilities of a pipeline during the summer when customer demand is low, and the withdrawal of those supplies during winter periods of higher gas consumption. Pipeline rates for storage service usually consist of a capacity charge (reserving a given volume of space), injection and withdrawal charges for movement of gas, and a commodity charge based on the actual volumes in storage.
The estimated amount of service which has been rendered but not billed at the end of any accounting period.
Value of service
The recognition that the provision of service may have a value to the customer different than the cost of providing service.
