Navajo Coal-Fired Power Plant at Night. Located in northern Arizona on the Navajo Indian Reservation near Page, the facility has three 750-megawatt (total 2280 MW), coal-fired (fueled), steam-electric generating units. An electric railroad delivers coal to the plant from a mine on the Navajo and Hopi Indian Reservations at Black Mesa in northern Arizona. The plant is operated by Salt River Project, and is owned by a partnership of five utility companies and the U. S. Bureau of Reclamation. The power plant has three 236 meter-high smokestacks, which are among the tallest structures in Arizona. The power plant is served by coal mined at the Kayenta Mine near Kayenta, Arizona, and hauled by the Black Mesa and Lake Powell railroad. The Kayenta mine ships about 8 million tons of coal each year to the power plant.
