BRIDGER COAL COMPANY
Jim Bridger Plant is named for the renowned explorer and mountain man, John Jim Bridger.
His pioneering spirit is alive today in the way this power facility has responded to its role as a low-cost energy producer, resource manager
and environmental steward. Energy, a natural resource. A massive amount of energy is held by nature beneath the rugged, beautiful face
of Wyoming: oil, gas, uranium, coal.
That geologic legacy is the foundation of what today is one
of the largest electric generating complexes in the Rocky
Mountain area: the coal-fueled Jim Bridger steam-electric plant.
Sub-bituminous coal stretches out for miles just beneath
the surface of southwestern Wyoming; the product of
forests and swamps changed by time into vast coal seams.
It is the energy locked in that coal that enables this facility
to produce up to 2,119,000 kilowatts of electricity per hour
from four generating units. That electricity serves people
throughout the West. To get the job done requires the talents
of nearly 350 skilled and dedicated Wyoming residents.
People, power and production
Converting coal into electric energy available at the flip
of a switch can be described in just a few words: coal is
burned to produce high-pressure steam that spins large
turbine-generators, which produce electricity. In practice,
this process requires a complex blending of systems.
Four operating units, each with a 2,800-degree furnace,
produce 1,000-degree steam, which turn turbines.

TYPES OF COAL
Coal is commonly divided into four “ranks” based primarily on the heat content.
Lignite: Lignite (often called brown coal) is brownish-black with a high moisture content. It has the lowest heat value. Lignite ranges from partially decayed peat to a final gel-like material. Lignite mines in the U.S. are located primarily in Montana, North Dakota, Louisiana, and Texas.
Sub-bituminous coal: Sub-bituminous coal forms from the lignite gel that has been heated to at least 1500 F. It is harder, blacker, and has a higher heat content than lignite. Wyoming’s coal is sub-bituminous. Major reserves of sub-bituminous coal are also found in Montana, Colorado, New Mexico, Washington, and Alaska.
Bituminous coal: Higher, longer lasting temperatures acting on sub-bituminous coal result in the formation of bituminous coal). Bituminous coal (often called hard coal) has a higher heat content than lignite or sub-bituminous. In the U.S., bituminous coal is mined primarily in Appalachia and in the mid-western states of Iowa, Illinois, Indiana and Ohio.
Anthracite coal: Anthracite (also called hard coal) was formed when bituminous coal underwent even more heat over a longer time and is usually associated with mountain building forces. Though rare, anthracite has the highest heat content. Pennsylvania’s anthracite coal seams are the largest in the world.
