Financial overview and charts

We are proud of our track record of delivering solid, long-term financial results, strong earnings, and dividend growth. Our 2017 earnings reflect the announcement in late 2017 that we would divest our oil and gas business. Earnings results for the previous five years have been restated to reflect oil and gas as discontinued operations.

The table below summarizes our stock performance and key financial indicators over the last three years. The financial information clearly shows the financial impact from our February 2016 acquisition of SourceGas, which added four natural gas utilities and a natural gas transmission system to our natural gas utility portfolio.

Understanding the Regulatory Compact

Our electric and natural gas utilities operate under a set of regulations determined by state public utilities commissions and federal agencies. As a regulated utility company, Black Hills is granted the exclusive right to sell electricity and natural gas in a defined service territory.  In exchange, Black Hills operates under a set of conditions known as the “regulatory compact:”

  • Duty to serve: We will provide service to any residence or business that requests it within our defined service territory. Utilities cannot pick and choose their customers.
  • Cost of service pricing: The pricing for electric and natural gas services is regulated and determined by the costs we incur to generate and deliver this energy to our customers. Utilities can only charge customers for investments that have been deemed “used and useful” for providing utility service. We are granted the ability to recover our costs of doing business and the opportunity to earn a reasonable rate of return on our utility capital investments.
  • Resource planning process: Every few years, we go through a process governed by our state utility commissions to assess the resources necessary to serve customers’ future energy needs. Energy resource plans must be reviewed and approved by regulatory commissions in an open, public process so that our customers and other stakeholders are given the opportunity to provide input on the plans.
