Two plants, Arapaho and Cherokee, are located in the Denver area, the Cameo plant is near Grand Junction, Pawnee is located at Brush, Valmont at Boulder and Comanche near Pueblo. The Arapaho and Pawnee plants burn Powder River coal while the Cameo plant burns coal from Utah. The other three plants burn Colorado coal.
