            PSCo and SPS to Combine in Merger of Equals
       Utilities Join to Compete in Evolving Energy Industry

        DENVER, COLO. AND AMARILLO, TEXAS --  Southwestern Public
   Service  Company (NYSE:SPS),  based  in  Amarillo, Texas,  and
   Denver-based  Public   Service  Co.  of   Colorado  (NYSE:PSR)
   announced Wednesday  that they have entered  into a definitive
   merger agreement to combine two low-cost utilities and form  a
   new energy services holding company that will cover one of the
   largest geographic areas in the country.
        This "merger of equals" - which is subject to approval by
   shareholders   of  both   companies  and   various  regulatory
   authorities  - was  unanimously  approved by  both  companies'
   boards of directors in separate meetings Tuesday.
        Bill D. Helton, SPS chairman and chief executive officer,
   and Del Hock, PSCo chairman and chief  executive officer, said
   the new company will build on the strengths of each partner.
        "We are extremely pleased with the natural synergies  and
   resulting savings of combining our  two companies, and we will
   be very well-positioned  to succeed in  our changing  electric
   utility industry," Hock said.
        Helton said  the  two companies  are  a natural  fit  and
   complement  each  other in  many  areas.   "As  both companies
   considered whether a merger was the right move, both wanted to
   ensure joining with  a company with low rates.   We found that
   in  each other.   The combination  will result  in one  of the
   premier low-cost energy providers of the future."
        Based  on fiscal  1994 results,  the new  holding company
   will have combined annual revenues of approximately $3 billion
   and  total assets of approximately $6  billion.  The companies
   expect  to save  approximately  $770 million  in the  first 10
   years after the merger is completed.
        Upon  completion of  the merger,  holders of  PSCo common
   stock  will receive one share of the new holding company stock
   for each share  of PSCo  stock.  Holders  of SPS common  stock
   will receive  0.95 shares of  the new holding  company's stock
   for each share of SPS  stock.  As of August 4, 1995,  PSCo has
   63.1  million  common shares  outstanding,  and  SPS has  40.9
   million common shares outstanding.
        Based on the  number of common  shares outstanding,  PSCo
   shareholders will own 61.9 percent of the common equity of the
   new holding  company, while  SPS  shareholders will  own  38.1
   percent.   The current combined market  capitalization of PSCo
   and SPS will result in a $3.2 billion market capitalization of
   the new holding company.
        It is anticipated that the holding company will adopt the
   SPS dividend  payment level, adjusted for  the exchange ratio.
   Based  on the exchange ratio,  the pro forma  dividend for the
   new  company will  be  $2.32 per  share  on an  annual  basis,
   following completion of the merger.
        Debt  holders and  preferred  stockholders will  continue
   with their present holdings under existing terms.

        According  to  Hock  and  Helton,  the  anticipated  $770
   million  savings  during  a  10-year  period  will  allow  the
   operating companies to  provide "very competitive" electricity
   rates in both service areas for many years to come.  They said
   specific rate  plans would  be  filed with  appropriate  state
   public utilities commissions and the Federal Energy Regulatory
   Commission in the near future.
        According to Helton, PSCo adds a faster-growing  service-
   area economy,  natural gas utility  operations, and innovative
   approaches to information technology and energy services.  SPS
   brings strong generation  and engineering, diversity  of power
   plants and fuels, and success with wholesale markets  and non-
   regulated generation projects.
        Hock  noted that  customers also  would benefit  from the
   adoption of the "best practices"  of each company, the sharing
   of generating  capacity and increased  leverage in purchasing.
   "We  will have lower fuel  costs for generation;  we can defer
   additional  generating  capacity;  and  we  can  reduce  total
   inventories," Hock said.
        The  new  company will  be  a  registered public  utility
   holding company,  which will be  the parent  company for  both
   Public Service Co. of Colorado and Southwestern Public Service
   Company.  The corporate offices of the holding company will be
   in Denver,  with  significant  operating  functions  based  in
   Amarillo.   SPS   and  PSCo   will   maintain   their  company
   headquarters in Amarillo and Denver, respectively.  The  board
   of  the new  holding  company will  consist  of eight  current
   directors from PSCo and six current directors from SPS.
        Upon the expected completion of the merger in early 1997,
   PSCo Chairman  and  Chief  Executive  Officer  Del  Hock,  who
   currently  is 60  years old,  will retire.   SPS  Chairman and
   Chief Executive Officer  Bill D. Helton,  56, will become  the
   company's  chairman  and   chief  executive  officer.     PSCo
   President and  Chief Operating Officer Wayne  H. Brunetti, 52,
   will  become  vice  chairman, president  and  chief  operating
   officer of the new company.
        On  June  30, 1999  (or  two-and-a-half  years after  the
   merger is  completed,  whichever comes  later), Brunetti  will
   assume  the responsibilities  of CEO,  and Helton  will remain
   chairman.  On May  31, 2001, Helton will retire,  and Brunetti
   will add the responsibilities of chairman of the board.
        The merger is subject to  approval by the shareholders of
   both companies.   The merger  is also subject  to approval  or
   regulatory review by the Federal Energy Regulatory Commission,
   the  Securities  and Exchange  Commission,  the Federal  Trade
   Commission, the Department of Justice,  the Nuclear Regulatory
   Commission  and  state  regulators  in  Texas,  Colorado,  New
   Mexico, Wyoming,  Oklahoma and  Kansas.   The  companies  have
   received  fairness opinions  from Barr  Devlin  Associates for
   PSCo and Dillon, Read & Co. for SPS.
        Brunetti said the merger agreement has the key element to
   succeed.   "I  have  long believed  that  if you  can  satisfy
   customers,   you  will   be  successful.     This   merger  is
   unquestionably a  step that enhances  our ability to  give our
   customers what  they want and what they want most of all - low
   price," Brunetti said.  "Price is the entry point into today's
   energy market."
        Brunetti  said   a  transition   team   -  made   up   of
   representatives of  both companies - would  be responsible for
   making recommendations to cut costs  and take advantage of the
   natural synergies.   He said he  expected employee  reductions

   would be  approximately 8  percent  of the  consolidated  work
   force  of both  companies.   That  figure  equals 550  to  600
   positions  out of  the combined  work forces  of approximately
   7,000 employees.
        "We pledge  to keep employees, customers and shareholders
   informed throughout this transition period," Brunetti said.
        After the merger, a new  transmission line will be  built
   that connects SPS  with PSCo through  a high voltage,  direct-
   current interconnection.
        Helton said the interconnection will  enhance competition
   in the  region's wholesale  power markets  and will  make  the
   generation and fuel savings possible.
        Upon completion of the merger, the new company will serve
   approximately  1.5 million  electric  customers  in  Colorado,
   Texas, New Mexico, Wyoming, Oklahoma  and Kansas.  The company
   also will provide natural gas service to  933,000 customers in
   Colorado and Wyoming.
        SPS, based in  Amarillo, is a  regional electric  utility
   that primarily provides  service to a population  of about one
   million people in a 52,000-square-mile area comprising eastern
   and southeastern New Mexico, the South Plains and Panhandle of
   Texas, the Oklahoma  Panhandle and southwestern  Kansas.   The
   company also  made wholesale  power  sales to  other  electric
   systems in 15 states last year.
        SPS's generating capacity  is 52 percent  coal-fueled and
   48  percent  from other  fuels,  primarily natural  gas.   The
   company has 12 power plants throughout its system.
        SPS subsidiary Utility  Engineering Corporation  provides
   engineering, design and construction management services to  a
   variety of industries.  Another subsidiary, Quixx Corporation,
   is involved  in  a  number  of  non-utility  power  generation
   projects, both nationally and internationally.
        Public Service Co.  of Colorado is  an electric,  natural
   gas  and thermal energy  utility, which  serves 32,000-square-
   mile area and a population of approximately 2.8 million people
   in  Colorado and in the Cheyenne, Wyo. area.  Headquartered in
   Denver, the company operates eight steam-electric plants, nine
   hydroelectric  facilities,  a downtown  Denver  thermal energy
   service and an extensive natural gas system.
        PSCo's fuel  for generation  is approximately 99  percent
   coal and 1 percent  natural gas.  Hydroelectric power  plays a
   role in this mix during the warmer months of the year.
        PSCo's subsidiary,  e prime, was started  in January 1995
   to provide value-added,  energy-related products and  services
   to energy-using  customers and  to  selected segments  of  the
   utility industry in  the United States.   Another  subsidiary,
   Natural Fuels Corp., is building an infrastructure for natural
   gas  vehicles,  and  it  sells  compressed  natural  gas  as a
   transportation fuel.
