      Calpine Reports on Nova Scotia Court's Decision in Harbert Litigation

     (SAN JOSE,  Calif.)  /PR  Newswire - First  Call/  August 3, 2005 - Calpine
Corporation  [NYSE:CPN]  today  announced  that the Supreme Court of Nova Scotia
("Court")  issued its decision  yesterday  regarding the  litigation  brought by
Harbert  Distressed  Investment Master Fund, Ltd.  ("Harbert").  This litigation
relates to the  outstanding  Calpine-guaranteed  bonds of  Calpine's  subsidiary
Calpine Canada Energy Finance II ULC ("Finance II").

     The Court dismissed Harbert's  application for relief and denied all relief
to Harbert and all other bondholders that purchased Finance II bonds on or after
September 1, 2004. However,  the Court stated that a remedy should be granted to
any  bondholder,  other than the Calpine  respondent  companies,  that purchased
Finance II bonds prior to  September  1, 2004 and that  continues  to hold those
bonds on August 2, 2005.

     The Court directed  Wilmington  Trust  Company,  Trustee for the Finance II
bonds,  to provide the face amount of  qualifying  bonds and the identity of the
holders of such bonds by August 31, 2005. The Court stated that, upon receipt of
the  information  from the Trustee,  it will then issue a final order  requiring
Calpine to maintain in the control of its subsidiary  Calpine  Canada  Resources
Company ("CCRC")  sufficient proceeds from the sale of the Saltend Energy Centre
to cover the face amount of such bonds. If there are  insufficient  proceeds for
this  purpose,  Calpine  will be  required  to place in the  control  of CCRC an
additional amount which, when added to the net Saltend sale proceeds, will cover
the face value of all such bonds. The final order will further provide that CCRC
shall diligently  conduct its business in a proper and efficient manner so as to
preserve and protect its business and assets. Pending the final order, the Court
issued an interim  order under which  Calpine must maintain the net Saltend sale
proceeds in the control of CCRC.

     Any party to the  proceeding has the right to appeal the final order to the
Nova Scotia Court of Appeal.
