In the year 1992, the Southern Company that held the Bowen plant, a coal-fired steam electric plant had to decide on the various options available to comply with the amendments in the Clean Air Act, effective 1995.
The Bowen plant was an unusually large plant with a capacity to serve the residential, commercial and industrial demands of 1 million people. The Bowen generators consumed 8.338 million tons of coal and generated 21,551 million kilowatt-hours of electricity.

* The electricity generated by the plant remains constant throughout the operation of the plant, that is, amount of electricity generated is 21,551 million kilowatt hours every year. * The amount of coal required to generate the electricity amount remains fixed to 8.338 million tons when high-sulfur coal is used and 8.391 million when low-sulfur coal is used. * In 1990, the revenue generated by electricity is $5.6 cents per kilowatt hour on an average, and will more or less the same. * The rate of buying or selling allowances is estimated to be $250 in year 1995 and will increase at a rate of 10% every year till 2010.
