Black Hills Corporation

Black Hills Corporation is a strong, diversified energy company with a vision to be the energy partner of choice. Our utility operations include Black Hills Power - an electric utility and our legacy business that provides service to approximately 69,000 customers in the Black Hills region and sells surplus power in wholesale markets - and Cheyenne Light Fuel & Power, serving 39,800 electric customers and 33,300 natural gas customers in the greater Cheyenne, Wyo., area.

Additionally, our recently acquired Black Hills Energy utility operations provide electric services to approximately 93,300 customers in southeastern Colorado and natural gas utility services to approximately 524,000 customers in Colorado, Iowa, Kansas and Nebraska.

Our energy portfolio also includes non-utility businesses; Black Hills Exploration & Production produces oil and natural gas in New Mexico, Wyoming and Colorado. Enserco Energy provides wholesale natural gas marketing and producer services for natural gas and crude oil. The Wyodak coal mine in Wyoming's Powder River Basin supports the Company's low-cost, mine-mouth power generation. Black Hills also has a fleet of power generation facilities in Colorado, Wyoming and South Dakota that produce more than 1,000 MW of energy annually for our own utility customers as well as others.
