Jeffrey Energy Center (Jeffrey EC) is a sub-bituminous coal-fired
Jeffrey EC is a typical modern coal-fired energy center. Its primary mission is to convert the chemical energy available from its Wyoming Powder River Basin sub-bituminous coal supply into electric energy.
History
Jeffrey EC came into operation during the late 1970s in the wake of an energy crisis created by a quadrupling of world oil prices. Its inauguration in July, 1978 was heralded with a visit by Vice President Walter Mondale praising its use of domestic coal reserves at a time when many power stations were still using imported oil. The opening ceremonies included a performance by the US Army Golden Knights parachute team, and the arrival of a special train carrying company officials and state dignitaries from Topeka, Kansas.
The center was originally designed for four generating units, but was scaled back when the anticipated growth in demand for electricity did not materialize.
The
As of December, 2007, Foundation Coal has shipped approximately 220,000,000 tons of Powder River Basin Coal to Jeffrey Energy Center.
In April, 2021, Evergy stated that they planned to decommission unit 3 in 2030.[2]

Coal is delivered to Jeffrey EC by unit trains. Each unit train contains about 110 cars carrying 100 tons of coal per car, constructed of aluminum to conserve weight, and is approximately 1 mile (1.6 km) long.
Jeffrey EC burns the coal delivered by about 11 miles (18 km) of coal train cars each week. The heating value of this coal is about 8,400
Jeffrey EC has the capacity to generate 1,857
Jeffrey EC is not located close to any large bodies of natural water. Its cooling water supply comes from the Kansas River and two nearby wells.
The overall thermal efficiency of the energy conversion is about 33%. About 1/3 of the coal's chemical energy is converted to electric energy. The remaining 2/3 of the energy is rejected to the environment via cooling water evaporated as low-grade waste heat with poor
