     Calpine Corporation  ("Calpine"),  a Delaware corporation,  hereby notifies
the Securities and Exchange Commission that Saltend Cogeneration Company Limited
("Saltend")  is, and claims  status as, a  "foreign  utility  company"  ("FUCO")
within the meaning of Section 33 of the Public Utility  Holding  Company Act, as
amended ("Act").

Item 1.  Name, Business Address, Facilities and Ownership.

     The name and business address of the company claiming FUCO status is:

         Saltend Cogeneration Company Limited
         Saltend Energy Centre
         Hedon Road, Hull
         HU12 8GA
         United Kingdom

     On December 12, 1997,  Entergy Power  Development  Corporation  ("Entergy")
filed a Form U-57 on behalf of Saltend with the  Commission.  Saltend was formed
by Entergy to  develop  and own a 1,200  megawatt  ("MW")  (nominal)  gas-fired,
combined cycle electric  generating facility to be located adjacent to a British
Petroleum  Company facility in the County of Hull,  England (the "Saltend Energy
Centre").  The Saltend Energy Centre entered  commercial  operations in November
2000.

     On August 24,  2001,  Calpine  completed  the  acquisition  of the stock of
Saltend  from  Entergy  and thereby  acquired  ownership  of the Saltend  Energy
Centre.

     The Saltend Energy Centre consists of three 400 MW (nominal) units, each of
which  includes  an air  intake  system  (including  a high  efficiency  filter,
pre-filter  and  silencer),  compressor,  combustion  chambers,  power  turbine,
exhaust system and all associated  auxiliary plant and control systems.  Calpine
will assume operations of the Centre through an affiliate.

     No person, other than Calpine and its subsidiaries owns a 5% or more voting
interest in Saltend.
