           Calpine Raises $101 Million Through Sale of Power Contract

     (SAN JOSE, Calif.) /PR Newswire - First Call/ May 26, 2004 - As part of its
program to enhance liquidity and reduce debt, Calpine Corporation [NYSE:CPN] has
sold its power  contract  related to the  118-megawatt  Parlin  and  58-megawatt
Newark Power Plants in New Jersey. With this sale Calpine raised $101 million in
cash, after transaction costs and a payment to retire  approximately $79 million
of non-recourse project debt. In addition,  the company successfully lowered the
cost of power by more than 10% for its customer and ratepayers  while  improving
its regional operating flexibility to better serve the Pennsylvania, New Jersey,
Maryland (PJM) market.

     "Calpine and a valued customer benefit from this  transaction,"  stated Bob
Kelly,  Calpine chief  financial  officer.  "The  customer  continues to receive
reliable  power,  at more  competitive  rates.  Calpine  enhances its liquidity,
reduces debt and strengthens its competitive position in the PJM market."

     As   part  of   this   transaction,   Calpine   terminated   its   previous
unit-contingent  power  contracts.  This will  enable the company to operate its
Newark and Parlin Power Plants to more effectively respond to market conditions.
Calpine  since  entered into a new  contract to supply the customer  with market
power, and has subsequently  sold this contract to Morgan Stanley Capital Group,
Inc.  Together  with  Calpine's   584-megawatt   Onetelanuee  Energy  Center  in
Pennsylvania,  the PJM market is now being  served  the  through  the  company's
integrated system of power plants.
