The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
The adiabatic exchange of heat between air and a water spray or wetted surface. The water approaches the wet bulb temperature of the air, which remains constant during its traverse of the exchanger.
Industry:Energy
The number of Btus contained in a cubic foot of natural gas fully saturated with water under actual delivery pressure, temperature and gravity conditions. See BTU, DRY.
Industry:Energy
The volume of a perfect gas is inversely proportional to the absolute pressure at constant temperature.
Industry:Energy
A device for measuring the humidity in the air, employing a wet bulb and a dry bulb thermometer.
Industry:Energy
A method to allocate commodity costs by function to customer classes based on the Test Period volume level for that customer. See COST OF SERVICE.
Industry:Energy
A tapered projection, the position of which is fixed, coaxial with an orifice which can be moved with respect to it, to regulate the flow of gas.
Industry:Energy
Applicable to pipelines which have a PGA mechanism in effect. The Current Adjustment is a rate component in a pipeline's tariff used to reflect the difference between 1) the current weighted average projected purchased gas costs and 2) the weighted average projected purchased gas costs reflected in the effective period of the previous scheduled PGA.
Industry:Energy
In rate base determination. See ORIGINAL COST, HISTORICAL COST, WEIGHTED COST.

The term "meter rate" is applicable to any method of charge for gas service based solely upon quantity, such as Mcf or therms used. Declining Block. The term "block" indicates that a certain specified price per unit is charged for all units of gas taken within specified increments of use. Reduced prices per unit are charged for all or any part of succeeding blocks of such units, each such reduced price per unit applying only to a particular block or portion thereof. Inverted. The term "inverted" indicates that an increasing unit charge will be applied to succeeding blocks of increasing energy use. Step. The term "step" indicates that a certain specified price per unit is charged for all gas taken during a billing period, the rate, or price depending on the particular step within which the total consumption falls. Straight-Line (Flat). The term "straight-line" indicates that the price charged per unit is constant, i.e., does not vary on account of an increase or decrease in the number of units.
