Naughton
Power Plant
Overview
The
Naughton Plant is a three unit coal-fired power plant located
in Lincoln County, Wyoming. The site consists of approximately
1120 acres at an elevation of 6900 feet above sea level. The plant
property is adjacent to coal deposits being mined by Pittsburg
and Midway Coal Mining. Pittsburg and Midway Coal Mining delivers
coal to the plant from its mine on a 4200-foot, 54-inch belt conveyor
which transports coal from the mine to the plant.

Plant Facts
The
plant consists of three units. Unit 1 has generating capacity
of 160 megawatts and has a Combustion Engineering natural circulating
boiler and a General Electric turbine/generator. The unit has
a closed loop cooling system with a mechanical draft cooling tower.
Unit
2 has a capacity of 210 megawatts and has a Combustion Engineering
natural circulating boiler and a General Electric turbine/generator.
Unit
3 has a capacity of 330 megawatts and has a Combustion Engineering
forced circulating boiler and a Westinghouse turbine/generator.
Water
Supply
Water
for plant operation is extracted from the Hams Fork River. A water
balance study estimated that the station consumes approximately
10,000 acre feet per year when operating at a capacity factor
of 80%.
The
Viva Naughton Dam is located on the Hams Fork River 15 miles upstream
from the plant. The dam is an earthen embankment approximately
70 feet high and 3200 feet long. The drainage area above the dam
contains 235 square miles and collects about 100,000 acre feet
of water annually. The dam impounds 45,370 acre feet of water
at the normal pool elevation of 7242 feet. Two hydro plants were
installed at the toe of the dam in 1986. They are induction type
generators rated at 567kw and 173kw. Both hydro plants are fully
automatic. Water for the plant is released from the reservoir
at a sufficient rate for the plant and town’s requirements.
A diversion dam and pump station is located on the river approximately
eight miles north of the plant. Water is conveyed to the plant
site by pipeline.
iamondville
is blessed with all the modern utilities, thanks in large part
to the surrounding land, which is rich in coal, oil, gas, and
water. We are fortunate to have the modern conveniences of telephone
service, cell phone service, and Internet providers. Yes, we are
in the 21st century.
