1. Why is the company raising its rates?
BHP is requesting recovery of costs associated with construction of the Wygen III power plant and other generation, transmission and distribution investments along with increased operating expenses since 1995.
2. How much will my bill go up?
If approved as requested, a typical residential customer in Wyoming using an average of 600 kilowatt-hours (kWh) of power each month will see an increase of $19.44 per month, or about 64¢ per day. Actual changes in each customer’s monthly bill will vary based on tariff and electricity use.
The increase experienced by commercial and industrial customers will vary depending on the rate class, load factor and amount and nature of use. Key account meetings will be held to discuss specific commercial and industrial customer impacts.
3. When will this rate increase be effective?
The proposed increase requires approval by the Wyoming Public Service Commission. The Wyoming Public Service Commission will hold a public hearing to discuss the proposed filing in spring of 2010. The company anticipates new rates will be effective April 1, 2010.
4. When was your last base rate increase?
Black Hills Power’s last base rate increase in Wyoming of 8.97 percent was based on 1994 costs and became effective in August 1995.
5. How do Black Hills Power’s rates compare with other providers?
With the proposed increase, Black Hills Power’s residential customer rates are in-line with rates currently charged by other electricity providers in our region as indicated in the graph below.
Both MDU and Rocky Mountain Power have filed rate increases pending approval from the Wyoming Public Service Commission.

6. What is Black Hills Power doing to control costs?
Black Hills Power has worked hard to keep rates stable for 15 years and continues to work diligently to control costs. Prudent management of assets and employees operating efficiently allow Black Hills Power to reduce the frequency and dollar amount of rate filings.
Since 1995 the Consumer Price Index has increased by 41 percent overall. Similarly, the national average retail price of electricity has increased by about 38 percent. In comparison, your price for electricity has remained stable for 15 years.

7. Why did you need a new power plant?
Since 1995, Black Hills Power residential electricity use in Wyoming has increased by 33 percent and commercial use by 28 percent. Thus, it was necessary for Black Hills Power to add a new generation facility – Wygen III – to our generation fleet and other utility infrastructure to keep up with current and future demand from our customers.
8. Why did you choose to build a coal-fired power plant?
Black Hills Power is committed to providing reasonably priced electricity for our customers. Our 2007 Integrated Resource Plan confirmed the need for the Wygen III generation, both the megawatts needed & the fuel type selected, based on least cost planning to meet projected customer load.
Black Hills Power has a proven track record of building generation on-time and on-budget. Construction and operating costs for Black Hills Power’s Wygen III generating facility compare favorably to other facilities; for example Basin Electric’s Dry Fork Station planned investment amounts to $2597 per kW ($1 billion for 385 MW) versus our Wygen III constructed for $2470 per kW.
9. What other investments have you made in the electric system?
Black Hills Power has invested over $400 million in utility infrastructure over the past 15 years to improve reliability and serve the growing customer demand for electricity.
10. How is Black Hills Power planning to integrate renewable energy?
Black Hills Power has voluntarily incorporated 35 MW of renewable energy into our supply portfolio from the Happy Jack wind farm and Silver Sage wind farm, both near Cheyenne, Wyoming. We will continue to explore cost-effective renewable energy resources for our customers.
11. What is Black Hills Power doing to reduce carbon emissions?
Wygen III will be one of the cleanest coal-fired power plants in the nation, using state-of-the-art emissions control and water conservation technology.
The plant design and location will allow for potential capture and sequestration of carbon dioxide as new technologies are developed in the future.
12. What is Black Hills Power doing to help customers save energy?
