        CALPINE COMPLETES SALE OF PG&E NOTE RECEIVABLE FOR $133.4 MILLION

     (SAN  JOSE,  CALIF.)  Dec.  4,  2003 /PR  NEWSWIRE  - First  Call/  Calpine
Corporation  [NYSE:CPN]  today  announced  that  it  has  sold  to  a  group  of
institutional  investors its right to receive  payments under a note  receivable
from Pacific Gas and Electric Company (PG&E) for approximately $133.4 million in
cash.

     "The sale of the PG&E note receivable  represents the successful completion
of  another   liquidity-enhancing  event,"  noted  Bob  Kelly,  Calpine's  chief
financial officer.  "To date we have completed liquidity  transactions  totaling
over $2.3 billion. Our last major liquidity event, the $250 million construction
financing  for our Rocky  Mountain  project,  should be completed in the next 30
days, bringing the total liquidity raised in 2003 to nearly $2.6 billion."

     Proceeds  from  the  sale  will be used  for  general  corporate  purposes,
including the  repurchase of  outstanding  public  indebtedness  in  open-market
transactions, and as otherwise permitted by the company's indentures.

     The PG&E note  receivable  stems from a 1999  restructuring  of a long-term
power purchase agreement with PG&E for electricity  delivered from the company's
Gilroy  Power Plant.  Calpine will  continue to own and operate the Gilroy Power
Plant, a 112-megawatt  combined-cycle natural gas-fired facility, which supplies
power to the  northern  California  power  market and steam to an adjacent  food
processing facility.

     Calpine  is a  fully  integrated  power  company  that  owns  and  operates
electricity   generating  facilities  and  natural  gas  reserves.  The  company
generates  power at plants it owns or leases in 21 states in the United  States,
three  provinces in Canada and in the United  Kingdom.  Calpine also owns nearly
900 billion cubic feet  equivalent of natural gas reserves,  Calpine focuses its
marketing and sales  activities on securing power  contracts  with  load-serving
