About Our Non-regulated Energy

For more than five decades, Black Hills Corp. has supplemented its revenue and earnings streams through non-regulated energy investments. The non-regulated energy businesses comprise about 40 percent of our total assets and are headquartered in Denver, Colo.

Our non-regulated energy businesses oversees power generation, oil and natural gas production and coal mining. These operations are logical adjuncts to our utility roots
in many respects.

For example, our experience in power generation planning, construction, compliance and operation made it possible for us to enter the independent power production sector in 2000. Our production of coal, natural gas and crude oil serves as a direct and indirect hedge for the fuel consumption of our power generation fleet. Most of all, at the core of our non-regulated energy performance is customer care, consistent with the Company’s focus.
