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 7 is an 142 MW pulverized coal-fired steam electric generating unit with a General Electric single reheat steam 

turbine, a Babcock & Wilcox steam generator and a Research-Cottrell reverse air baghouse for the control of 

particulate emissions.
