- Company Profile:
The operating control of an integrated electric system involving operations such as (1) the assignment of load to specific generating stations and other sources of supply to effect the most economical supply as the total or the significant area loads rise or fall (2) the control of operations and maintenance of high-voltage lines, substations, and equipment; (3) the operation of principal tie lines and switching; (4) the scheduling of energy transactions with connecting electric utilities.
Industry:Energy
The removal of natural, synthetic, and/or supplemental gas, or any components or gaseous mixtures contained therein, from the responding company's facilities within the report State by any means or for any purpose, including the transportation of such gas out of the report State.
Industry:Energy
A grade of coal made from compressed coal dust, with or without a binding agent such as asphalt.
Industry:Energy
A set of categories used to account for how crude oil and petroleum products are transferred, distributed, or removed from the supply stream. The categories include stock change, crude oil losses, refinery inputs, exports, and products supplied for domestic consumption.
Industry:Energy
A grade of coal that has been processed to reduce the amount of impurities present and improve the burning characteristics.
Industry:Energy
A general classification for one of the petroleum fractions produced in conventional distillation operations. It includes diesel fuels and fuel oils. Products known as No. 1, No. 2, and No. 4 diesel fuel are used in on-highway diesel engines, such as those in trucks and automobiles, as well as off-highway engines, such as those in railroad locomotives and agricultural machinery. Products known as No. 1, No. 2, and No. 4 fuel oils are used primarily for space heating and electric power generation.
Industry:Energy
A grade of coal or a blend of coal, that meets sulphur dioxide emission standards for air quality without the need for flue-gas desulfurization.
Industry:Energy
The primary distillation unit that processes crude oil (including mixtures of other hydrocarbons) at approximately atmospheric conditions. It includes apipe still for vaporising the crude oil and a fractionation tower for separating the vaporised hydrocarbon components in the crude oil into fractions with different boiling ranges. This is done by continuously vaporising and condensing the components to separate higher oiling point material. The selected boiling ranges are set by the processing scheme,the properties of the crude oil, and the product specifications.
Industry:Energy
A grade of coal that are waste materials from preparation plants. In the anthracite region, culm consists of coarse rock fragments containing as much as 30 percent small-sized coal. Silt is a mixture of very fine coal particles (approximately 40 percent) and rock dust that has settled out from waste water from the plants. The terms culm and silt are sometimes used interchangeably and are sometimes called refuse. Culm and silt have a heat value ranging from 8 to 17 million Btu per ton.
Industry:Energy
A generator that is located close to the particular load that it is intended to serve. General, but non-exclusive, characteristics of these generators include: an operating strategy that supports the served load; and interconnection to a distribution or sub-transmission system (138 kV or less).
