Colorado Springs Utilities Martin Drake Power Plant consists of three coal-fired, steam driven electric generating 

units designated Units 5, 6 and 7, for the generation of commercial electricity. The Martin Drake Power Plant is 

located at 700 South Conejos Street, Colorado Springs, Colorado.

Unit 5 is a 51 megawatt (MW) pulverized coal-fired steam electric generating unit with a Westinghouse superheat 

steam turbine, a Riley Stoker steam generator and a Marsulex reverse air baghouse for the control of particulate 

emissions.
