     The following  press release was issued by Endesa,  S.A. (the  "Company" or
"Endesa") on September 6th, 2005. Endesa shareholders are urged to read Endesa's
Solicitation/Recommendation  Statement on Schedule 14D-9 when it is filed by the
Company with the U.S. Securities and Exchange Commission (the "SEC"), as it will
contain important  information.  The  Solicitation/Recommendation  Statement and
other  public  filings  made from time to time by the  Company  with the SEC are
available  without  charge  from the SEC's  website  at  www.sec.gov  and at the
Company's principal executive offices in Madrid, Spain.

                                      * * *


                                  RELEVANT FACT


Endesa's  (NYSE:ELE)  Board of Directors,  in a meeting held today, has analysed
the terms of the  tender  offered by Gas  Natural.  According  to the  available
information, the Board has considered convenient, for the benefit of the general
interest,  its  shareholders  and its  employees,  and the  market,  unanimously
express a preliminary evaluation of the transaction in the following terms:

     1.   The  transaction  proposed  by Gas  Natural  has been  presented  in a
          hostile way without any previous knowledge by Endesa.

     2.   The  layout  and the  structure  of the offer  introduce  elements  of
          uncertainty  rendering it impossible  to determine  with detail enough
          the real  value of  offered  price.  In any case,  a first  evaluation
          determines   that  the  economic   terms  of  the  offer  are  clearly
          insufficient  and do not  reflect  by any means the fair  value of the
          Company.

     3.   Considering the applicable  legislation and existing precedents in the
          Spanish and in the European  Community,  the transaction may be hardly
          compatible   with  the  current   regulatory  and  antitrust   regime.
          Therefore,  there are risks not taken  into  consideration  that could
          imply significant adverse consequences to Endesa's shareholders.

     4.   The layout of the  transaction  in a time  where a full  review of the
          electricity regulation is taking place is particularly  surprising and
          worrying.  Furthermore,  the preliminary  conclusions of the mentioned
          review seem to be completely opposed to the proposed transaction.

     5.   The participation in the transaction of the main Company's  competitor
          under the proposed  terms  presents  serious  concerns  regarding  the
          protection  of minority  shareholders'  interests.  Furthermore,  this
          participation  does not comply  with  Spanish and  European  Community
          existing antitrust decisions.





This  preliminary  evaluation  is without  prejudice to the report that Endesa's
Board of  Directors  should issue in case of the approval of the tender offer by
the CNMV  (Spanish  Stock  Exchange  Commission)  after  obtaining the remaining
pertinent administrative authorizations,  in compliance with the article 20.3 of
Royal Decree  1197/1991,  issued on 26th of July of 1991,  on the Takeover  Bids
Regime.

The Board of Directors endorses its commitment to the Company's Business Plan on
a stand-alone  basis,  since it's one of the five European  largest  electricity
groups, the first private electricity Company in Latin America and the leader in
the Iberian  market,  and it has a solid,  adecuate and ongoing  Strategic  Plan
which ensures growth and profitability.

Considering  all the above  mentioned,  the Board of  Directors  will  adopt all
available  legal  actions  in order to defend  both  Company  and  shareholder's
interests.
