APS runs a coal-fired power plant in New Mexico called Four Corners, located where the states of Colorado, Arizona, New Mexico and Utah all meet at one geographical point. The Four Corners plant generates 2,040 megawatts of power, making it one of the largest coal-fired power plants in the U.S., capable of powering 300,000 homes with electricity. The plant uses ten million tons of coal each year, and all of it is mined from a nearby Navajo-owned mine. To increase the power-generation efficiency of its Four Corners facility, APS decided to install software from Wonderware, a business unit of Invensys Systems, Inc.
