BLACK HILLS CORPORATION ANNOUNCES RATE REQUEST FOR

BLACK HILLS POWER

RAPID CITY, SD—June 30, 2006—Black Hills Corporation (NYSE:BKH) today announced that its subsidiary, Black Hills Power, Inc., has filed a request for a rate increase with the South Dakota Public Utilities Commission.

The filing calls for a $9.5 million, or 9.5 percent, increase in revenue. The proposed increase affects all classes of customers in a comparable manner. The filing proposes annual cost adjustments as needed to address the challenges of volatile fuel and purchased power prices and transmission charges, which affect the cost of power delivery. Proposed cost adjustments would also require the Company to absorb a portion of any cost increases, depending in part on potential earnings derived from off-system power sales. The Company requested the new rates to go into effect January 1, 2007. The proposed increase affects South Dakota customers, who represent approximately 90 percent of the retail customer base of Black Hills Power. These customers have experienced no changes in the price of power since 1995.

These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to

a number of risks and uncertainties that, among other things, could cause actual results to differ materially

from those contained in the forward-looking statements, including the risk factors described in Items 1 and 2 of our 2005 Annual Report on Form 10-K and in Item 2 of Part I of our quarterly reports on Form 10-Q filed with the SEC, and the following:

•	Delays in obtaining regulatory approval or having cost recovery disallowed in our retail rate proceedings will affect our projected revenues and results of operations.
•	The timing and extent of changes in energy-related and commodity prices, interest rates, energy and commodity supply or volume, the cost of transportation of commodities, and demand for our services, all of which can affect our earnings, liquidity position and the underlying value of our assets;
