The Future of Electricity

Coal: the key to reliable, affordable electricity

People involved in using coal to generate electricity call coal the "essential and affordable" fuel to provide electric power for America. This month's column supplies the facts and figures that back up those claims, nationwide and in Kentucky.

Essential
"Essential" means "basic, indispensable, necessary" as well as "of the utmost importance." After food, energy is the next largest commodity bought and sold in America. Our appetite for all the things electricity powers, from the equipment to process milk on the farm to the refrigerator cases to keep it cold at the grocery, to television sets and factory machinery, lights and equipment in hospitals and hotels and in our homes, electricity is an integral part of our lives day and night.
One industry group puts the value of electricity sales at more than $200 billion a year. Nationwide, America's homes, farms, factories, and other businesses use thousands of billions of kilowatt-hours of electricity each year. Electricity sure is an essential part of our lives and economy, but how does coal fit in?
According to the Energy Information Administration of the U.S. Department of Energy, for the year 2000, the electric power industry used a record high of 970.7 million tons of coal. That coal fueled 51.4 percent of the total electric generation nationwide that year. (The next nearest power source was nuclear, which generated a mere 21 percent of America's electric energy.) So coal is the clear industry leader, producing more than half of the electricity generated throughout the United States.
Here in Kentucky, coal's role in the energy business is even more dramatic: the 22 major coal-burning electric generating plants within the state produced a huge 96 percent of the electricity generated in the state during 1998.
Kentucky's two coal fields, the Appalachian in the eastern part of the state and the Interior in the west, play a vital-make that essential-role in supplying coal to electric utilities in 24 other states, too. During 1998, almost 77 percent of Kentucky's coal was sold to out-of-state utility company buyers; 64 of them bought more than 120 million tons of Kentucky coal for 138 electric power plants.
Coal and electricity are connected in yet another essential way. Mike Thompson, technical advisor for power generation at Big Rivers Electric Corporation, one of three generating entities for Kentucky's 24 distribution co-ops, notes the infrastructure (things like fleets of barges, railroad lines and railroad cars, even trucks) to move coal from the fields to the generating plants is already in place.
Thompson then adds another essential feature of coal, its abundance.
"With more than 200 years of reserves still in the ground," Thompson says, "coal is a very important 'in-country' asset."

Affordable-and consistent
Thanks to Kentucky's major coal fields, electric rates in our state were the lowest in the nation, according to the U.S. Department of Energy's latest monthly preliminary estimates from June 2001. And not only do states such as Kentucky, which rely almost exclusively on coal to generate electricity, have the lowest costs per kilowatt-hour, the stable price of coal helps keep those rates consistent.
During the last 15 years, coal has consistently been priced lower than the other two major fossil fuels, petroleum and gas. Nationally, the costs of petroleum and gas sometimes spike at twice the cost of coal, which remains quite predictable. So even in states where coal is a much smaller percentage of the mixture of fuels used to generate electricity, coal's stable prices add a valuable portion of consistency to those states' costs.
