              <em>DENVER, Dec 28, 2005 -- BUSINESS WIRE </em>
              <p>&nbsp;</p>
              <p>Xcel Energy announced today that it intends to acquire 775 
              megawatts of new wind power capacity for its Colorado system by 
              2007. The additional capacity would make Xcel Energy the nation's 
              largest utility user of wind power. </p>
              <p><ECLINKS>The announcement today is part of filings made with 
              the Colorado Public Utilities Commission (CPUC) on the company's 
              Least-Cost (Resource) Plan (LCP), a process designed to address 
              the state's growing energy demand. Xcel Energy also announced 
              today that it intends to acquire approximately 1,300 megawatts of 
              natural gas-fired generation from new and existing facilities 
              between 2007 and 2012. </p>
              <p>In addition, the company intends to acquire up to 30 megawatts 
              of energy efficiency supplied by bidders, known as Demand-Side 
              Management (DSM). Xcel Energy has committed $196 million in 
              company-sponsored initiatives for the remainder of the DSM 
              program, which would be an additional 290 megawatts. </p>
              <p>&quot;Xcel Energy has taken the leadership position among all 
              electric utilities in support of renewable energy -- both in 
              Colorado and throughout the country,&quot; said Pat Vincent, Xcel 
              Energy's president and chief executive officer for Colorado. &quot;We 
              are working to ensure that wind power is an integral part of our 
              nation's future energy supply.&quot; </p>
              <p>Xcel Energy -- which currently has 282 megawatts of wind 
              in-service or under-construction in Colorado -- would increase its 
              overall wind capacity in the state by 275 percent. Xcel Energy 
              estimates that it also would meet the non-solar mandates of the 
              voter-approved Renewable Energy Standard through 2014, essentially 
              meeting the standard seven years earlier than required. </p>
              <p>Companywide, Xcel Energy -- which operates in 10 states -- 
              expects to have more than 1,100 megawatts of owned or purchased 
              wind capacity on its system by early 2006, increasing to more than 
              2,300 megawatts of wind capacity by the end of 2007. This includes 
              more than 1,000 megawatts each in Colorado and Minnesota. </p>
              <p>Xcel Energy cautioned that while it is aggressively seeking to 
              add more wind power in Colorado, the ultimate success of 
              permitting, constructing and placing new wind farms into 
              commercial operation remains in the hands of independent wind 
              developers. </p>
              <p>&quot;While current economic conditions in the wind power industry 
              are challenging, we will closely work with our future wind 
              development partners in Colorado to see that their projects are 
              successful,&quot; Vincent said. &quot;The completion of these projects is 
              important to our customers and to Xcel Energy.&quot; </p>
              <p>Xcel Energy's estimates of its current and future wind power 
              capacity standing -- in relationship to other utilities -- is 
              based on a compilation of current and proposed wind projects 
              announced by utilities through various national wind power trade 
              associations, and is subject to change based on future 
              announcements. </p>
              <p>Also today, Xcel Energy filed with the CPUC a request to 
              shorten its planned resource acquisition period under the current 
              LCP to nine from 10 years. In an application filed today, the 
              company noted that conditions have changed since the original plan 
              was filed in April 2004, requiring it to reconsider its long-range 
              acquisition strategy. </p>
              <p>&quot;There are several recent economic, legislative and regulatory 
              uncertainties that we need to better understand before we commit 
              to another major resource that would come on line many years from 
              now,&quot; said David Eves, Xcel Energy vice president for resource 
              planning and acquisition. </p>
              <p>Specifically, Eves noted that the federal Energy Policy Act of 
              2005 places significant emphasis on improving the nation's 
              transmission grid, which could open up new generation resources 
              previously thought unavailable to the company's Colorado 
              operations. Likewise, the Colorado commission will hold future 
              resource planning and DSM hearings that could significantly alter 
              the rules for acquisition of future generation. </p>
              <p>The resource planning process occurs every four years in 
              Colorado, and is designed to determine the company's future energy 
              needs and identify the resources that would be acquired to meet 
              those needs. In the past decade, Xcel Energy has seen a 10 percent 
              growth in per-household electricity use, a 20 percent increase in 
              total customers and a 60 percent increase in peak demand for 
              power. </p>
              <p>Coupled with the addition of the 750-megawatt, coal-fired third 
              generating unit at the Comanche Generating Station in Pueblo, 
              Colo., the wind, natural gas and energy efficiency resources to be 
              acquired through the announcement today combine to give Xcel 
              Energy a very balanced and diversified supply portfolio, Eves 
              said. </p>
              <p>The acquisition of future wind power in Colorado is not a part 
              of Xcel Energy's premium customer &quot;green pricing&quot; program, known 
              as Windsource. Xcel Energy also notes that one megawatt of 
              generation can meet the electricity needs of approximately 1,000 
              homes in Colorado. </p>
