<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;David
R. Emery, Chairman, President and Chief Executive Officer of Black Hills Corporation,
said, &#147;The first quarter of 2005 showed a continuation of a normalized, historical
earnings pattern from our business segments. Sales of oil and natural gas production, on
an equivalent basis, increased about 13 percent in the first quarter, compared to the same
quarter in 2004. Combined with higher average product prices, oil and gas earnings
increased 35 percent. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Emery
continued, &#147;The dramatic improvement in power generation results reflects the
contracted status of the Las Vegas Cogeneration II power plant, which ran merchant in
difficult market conditions during the first quarter of 2004. Our fleet of independent
power plants performed well in the first quarter of 2005. Electric utility earnings were
down in 2005, due to increased purchased power and other costs. The Wyodak plant
experienced several unplanned outages during the first quarter. The major maintenance
outage for the plant, originally scheduled for later this year, has been deferred by
PacifiCorp, the plant operator, until the Spring of 2006. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#147;Energy
marketing was affected by commodity price increases late in the first quarter of 2005,
resulting in an unrealized $3.1 million mark-to-market accounting loss. From an
operational perspective, this business segment benefited from increased realized gross
marketing margins, partially the result of a 13 percent increase in average daily physical
natural gas volumes marketed. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#147;We
are very pleased with initial results from our newest acquisition, Cheyenne Light, Fuel
&amp; Power,&#148; said Emery. &#147;Recently, we filed a request for rate increases
effective January 1, 2006, which, if approved by the Wyoming Public Service Commission
(PSC), would increase revenues at the electric and gas utility by approximately $5
million. As part of our long-term power supply planning for Cheyenne Light, we also filed
an integrated resource plan with the PSC, which proposes the construction of a 90 megawatt
mine-mouth coal-fired power plant at our Wyodak energy complex near Gillette, Wyoming. We
would like to begin construction this year.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Emery
said, &#147;In April, we announced a definitive agreement to sell our Communications
business. Cash proceeds from the $103 million sale are expected to be used for debt
repayment or for investments in energy projects. The transaction is expected to be
completed by the end of June 2005.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Large Indent" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Emery
concluded, &#147;In addition to our goal of commencing construction on a new coal-fired
power plant, we continue to pursue other strategic goals, including sustaining the
production growth of our oil and gas operation, integrating Cheyenne Light into Black
Hills&#146; business operations and corporate culture, and pursuing balanced, risk-managed
energy projects in the West.&#148; </FONT></P>

common and preferred stock. Common shareholders will receive 32 cents per share,
equivalent to an annual dividend rate of $1.28. Preferred shareholders, whose holdings are
related to a Company acquisition, will receive $11.663 per share, an amount which
represents 1 percent per annum computed on the basis of $1,000 per share plus a common
stock dividend equivalence. Dividends will be payable June 1, 2005, to all shareholders of
record at the close of business on May 18, 2005. </FONT></P>

Power generation income from continuing operations was $3.9 million, compared to a loss of
($2.1) million in 2004. Earnings for 2005 were higher primarily due to increased earnings
at our Las Vegas Cogeneration II plant, which now operates under a long-term tolling
arrangement. In the first quarter of 2004, Las Vegas II was not under contract and
operated as a merchant plant, selling power into the market only when economic to do so. </FONT></TD>

Oil and gas income from continuing operations was $5.0 million compared to $3.7 million in
2004. Higher earnings were primarily the result of a 13 percent increase in volumes sold
at average hedged prices received that were 22 percent higher for oil and 4 percent higher
for natural gas. Operating expense increased 9 percent due to the increase in production.
However, on a per Mcf basis, lease operating expense decreased 16 percent. </FONT></TD>

Energy marketing income from continuing operations was $2.9 million in 2005 compared to
$4.0 million in 2004. The decrease was primarily due to a $3.1 million unrealized
mark-to-market pretax loss for 2005, compared to a $0.3 million unrealized pretax loss in
2004. Earnings benefited from an increase in realized marketing gross margins in part due
to a 13 percent increase in natural gas physical volumes marketed. </FONT></TD>

Coal mining income from continuing operations was $1.5 million in 2005 compared to $1.8
million in 2004. The decrease was primarily due to lower revenues, due to unplanned
outages at the Wyodak plant, our largest coal customer. The decrease in revenues was
partially offset by lower taxes and production-related costs. </FONT></TD>

Net income from the Electric utility business segment for the three months ended March 31,
2005 was $4.3 million, compared to $5.0 million in 2004. Decreased earnings in 2005 were
the result of increased purchased power expense due to unplanned outages at the Wyodak

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company&#146;s expectation for 2005 income from continuing operations has been revised
upward by $0.05 per share, to a range between $1.90 and $2.05 per share. The change is due
to two factors: the announced sale of the communications business segment, whose 2005
financial results would become reported as &#147;discontinued operations&#148; effective
for the second quarter of 2005; and the expected full-year availability of the Wyodak
power plant in 2005, as a major maintenance outage scheduled for the Fall of 2005 has now
been deferred to 2006. As stated in previous 2005 earnings guidance, the Company
anticipates continued earnings growth from increased oil and gas production; modest
accretion from the acquisition of Cheyenne Light, Fuel &amp; Power; an earnings increase
from power generation, due to a full year of contract revenues at the Las Vegas
Cogeneration II facility; and incremental cost savings from ongoing business integration
efforts. The Company expects a small decrease in 2005 earnings from energy marketing
operations, which anticipate reduced oil marketing and transportation revenues and
narrower margins from gas marketing. </FONT></P>
