Industry:Energy
One of the movable sections of a liquid-sealed gas holder. The vertical distance a liquid is pumped.
Industry:Energy
The concept that the value of a utility service to a consumer cannot be greater than the cost of an equally satisfactory substitute service or the consumer will switch to the substitute.

A billing procedure which provides for the billing of a portion of utility customers each working day so that all customers are billed within a predetermined period, such as one month, two months, etc. (In some companies, each day's billing is referred to as a "billing cycle day," "billing day," or "billing cycle." Other companies use "billing cycle" to refer to the total period which covers billing of customers within a specific period).
Industry:Energy
A geological liquid consisting of hydrocarbons and relatively small amounts of sulfur, nitrogen, and oxygen in the form of derivatives of hydrocarbons. Crude is formed under pressure from residual plant matter accumulated in a swamp over a period of time. It may come from the earth with varying quantities of water, gas, and other organic matter. Some crudes are very volatile and others are very viscous liquids. Crude oil may contain such impurities as sulphur and hydrocarbons. These are compounds containing a variety of combinations of carbon with hydrogen. There are a very large number of these compounds and they form the basis of a number of petroleum products. These compounds may exist as gases or liquids or solids. A number of hydrocarbons are also contained in bituminous coal, oil shale and tar sands. Crude is generally classified into three basic types: paraffin base crude oils contain a high degree of paraffin wax and little or no asphalt. Besides wax, they also yield large amounts of high-grade lubricating oil. Asphalt base crudes contain large proportions of asphaltic matter, and mixed base crudes contain quantities of both paraffin wax and asphalt. This is why crude oils do not always look alike. Some are almost colourless or pitch black. Others can be amber, brown or green. They may flow like water or creep like molasses. Some crudes, containing relatively large amounts of sulphur and other mineral impurities, are called "sour" crudes. Others, having a fairly low sulphur content, are called "sweet" crudes.

An accounting method under which decreases or increases in state or federal income taxes resulting from the use of liberalised depreciation and the Investment Tax Credit for income tax purposes are carried down to net income in the year in which they are realized. For rate-making purposes, the flow-through method passes on savings from liberalised depreciation and investment credit to the benefit of rate payers through lower rates.
