The unit of measurement of electrical
current produced in a circuit by 1 volt acting
through a resistance of 1 ohm.
Impurities consisting of silica, iron,
alumina, and other noncombustible matter that are
contained in coal.
Barrel: A volumetric unit of measure for crude oil
and petroleum products equivalent to 42 U.S.
Base Bill: A charge calculated through
multiplication of the rate from the appropriate
electric rate schedule by the level of consumption.
The minimum amount of electric power
delivered or required over a given period of time at
a steady rate.
Baseload Capacity: The generating equipment normally
operated to serve loads on an around-the-clock
A plant, usually housing high-efficiency
steam-electric units, which is normally operated to
take all or part of the minimum load of a system,
and which consequently produces electricity at an
essentially constant rate and runs continuously.
These units are operated to maximize system
mechanical and thermal efficiency and minimize
system operating costs.
The most common coal. It is dense and black (often
with well-defined bands of bright and dull
material). Its moisture content usually is less than
20 percent. It is used for generating electricity,
making coke, and space heating.
A device for generating steam for power, processing,
or heating purposes or for producing hot water for
heating purposes or hot water supply. Heat from an
external combustion source is transmitted to a fluid
contained within the tubes in the boiler shell. This
fluid is delivered to an end-use at a desired
pressure, temperature, and quality. Btu (British
Thermal Unit): A standard unit for measuring the
quantity of heat energy equal to the quantity of
heat required to raise the temperature of 1 pound of
water by 1 degree Fahrenheit.
