Indiana-Michigan Power

Indiana-Michigan Power is a wholly-owned subsidiary of American Electric Power (AEP). The power company is headquartered in Fort Wayne, Indiana, and serves portions of southwest Michigan as well as northeast Indiana. In total, the serviced areas are spread over 20,241 square miles and have a maximum transmission length of 3,980 miles. The various power plants employ 1,352 people in Michigan and 1,220 people in Indiana.

The customers are residential, commercial, industrial, and others. Over 500,000 customers are residential in the Indiana-Michigan territory; about 68,000 are commercial, just over 5,000 industrial, and about 2,000 other customers. Commercial customers include Steel Dynamics, Wal-Mart stores, Ball State University, Michelin North America, and Mittal Steel, among others. Combined, the plants produce 17,642,645 retail megawatt hours and 4,552,000 wholesale (sold to other power providers) hours. Average cost for residential customers is 7.81 cents per KW hour. The record peak outputs for the combined plants were 3,946 megawatts in the wintertime and 4,650 megawatts during the summer.

The plants get their power from a variety of sources. Coal is the top source of energy, with 60.7% of the power generated by Indiana-Michigan coming from coal-powered plants. The Rockport plant in Rockport, Indiana, has a max output of 2,600 megawatts, and Tanners Creek Plant in Lawrenceburg, TN has an output of 995 megawatts. The second-largest source of power is nuclear at 36.4%. The Cook Plant in southwest Michigan can produce 2,160 megawatts. Wind and hydroelectric power also provide some of the power. 150 megawatts coming from the Fowler Ridge wind farm. The hydroelectric power comes from six different sources which produce a combined output of 22.4 megawatts. Operating revenues were reported at just under $2.1 billion in 2009.

As with most power stations built before the late 1970s, Indiana-Michigan Power likely faced significant issues when it came to the effects that asbestos had on their workforce. This is because asbestos was commonly used for its fire and electrical-resistant qualities when building new power plants. In the early days of plant construction, few details of the harmful effects of asbestos were widely known. Consequently, former employees not yet exhibiting the symptoms of disease associated with asbestos exposure might still develop one of these conditions for years to come, as diseases related to exposure often lie dormant for 20 to 50 years.
