A geographical area. A geological zone, however, means an interval of strata of the geologic column that has distinguishing characteristics from surrounding strata. Also, a space or group of spaces within a building with heating and/or cooling requirements sufficiently similar so that comfort conditions can be maintained by a single controlling device.
Industry:Energy
A property of ions or of radicals determining the number of ions with which they can combine in chemical reactions.
Industry:Energy
An account prescribed by some state utility commissions, the accounting profession, and the FERC to record the accumulated balances (net after write-off) of the provisions made in prior years for income taxes to be paid in subsequent years.
Industry:Energy
Equipment or device that extracts or drives out vapors from liquid solutions or gases. Also, equipment that is part of refrigerating systems to permit liquid refrigerants to evaporate in the process of absorbing heat.

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.
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 sulfur 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 colorless 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 sulfur and other mineral impurities, are called "sour" crudes. Others, having a fairly low sulfur content, are called "sweet" crudes.
Industry:Energy
A proposal by the FERC to change its rules. Sometimes preceded by a Notice of Inquiry. Normally calls for comments from all interested parties and in some cases, reply comments and/or public hearings. A NOPR may or may not result in a final rule.
Industry:Energy
An accounting method under which decreases or increases in state or federal income taxes resulting from the use of liberalized 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 liberalized depreciation and investment credit to the benefit of rate payers through lower rates.
