The Combustion Gas Desulfurisation Project (CGD) at the Fossil Fuel Plant at Los Barrios Comes on Stream, ENDESA Continues with

ENDESA (NYSE: ELE):

   --  The Los Barrios project will entail an investment of Euro 82
        million and will be operative in 2006.

   --  The installation of the new CGD at this power station, which
        is equipped with a generating group of 567.5MW, will allow
        reductions in emissions of sulphur dioxide (SO(2)) of nearly
        90% and a 48% reduction of particles. It will also be able to
        treat 100% of the combustion gases from the boiler.

   --  Similar desulphurisation plants have already been installed at
        the Compostilla II, Litoral de Almeria and Teruel stations,
        while those at Alcudia, Granadilla and Barranco de Tirajana
        have desulphurisation installations which differ slightly in
        design.

   ENDESA (NYSE: ELE) has begun construction of a combustion gas
desulphurisation plant at the Los Barrios power station, located in
the province of Cadiz, as part of its ongoing Action Plan to reduce
gas emissions at the Company's fossil fuel plants in Spain.
   The Los Barrios project, which has installed capacity of 567.5 MW,
will cost Euro 82 million and be operative in 2008.
   The Los Barrios gas desulphurisation plant will treat nearly 100%
of combustion gases, leading to a significant environmental
improvement, with special attention being paid to the plant's
emissions and their impact on the environment. This installation will
bring about a reduction in emissions of sulphur dioxide (SO(2)) of
nearly 90% and 48% of particles. It will also treat almost 100% of
combustion gases.
   The desulphurisation technique chosen is the "wet" type. This is a
chemical process whereby the sulphur oxides produced in the carbon
combustion processes are captured and washed as they come out of the
boilers, they are then coated with limestone which reacts with the
sulphur dioxide (SO(2)) producing calcic sulphite. The sulphite is
then rusted by means of an injection of air and converted into calcic
sulphite, in other words, gypsum, which can then be used in the
construction industry. This desulphurisation system is the most widely
used worldwide and, given its efficiency rate, is especially useful
for coals with a high sulphur content.
   The main activity will be the reduction of sulphur emissions as
well as the modification of some electricity and control systems in
the existing plant in order to adapt them to the new working
conditions.
   In order to carry out this project, technology from ALSTOM POWER
ITALIA SpA will be used and will provide, in a consortium with INITEC
Energia S. A., the major equipment under a turn-key contract. Endesa
will provide the working teams, which will contribute their experience
in carrying out similar projects, as well as the Company's own
technology.
   The desulphurisation plant is a major modernisation which will
enable ENDESA to continue introducing cutting- edge technology to its
fossil fuel assets which are essential for the environmental
compatibility of its activities and in meeting the requirements of the
2001/80/EC Directive dated 23 October 2001 on limiting the emissions
of certain contaminating agents into the atmosphere from large
combustion plants (GIC Directive) which was translated into Spanish
legislation by the 430/2004 Royal Decree of 12 March 2004.
   The installation of the new desulphurisation plant will enable
ENDESA to continue with its action plan to reduce power station
emissions contained in its Strategic Plan. In this sense, ENDESA
already has plants installed at its Teruel (Andorra-Teruel),
Compostilla (Ponferrada-Leon), Litoral de Almeria (Almeria), Alcudia
(Mallorca), Granadilla (Tenerife) and Barranco de Tirajana (Gran
Canaria) power stations which are showing positive results.
   The wet system has been installed at the Teruel, Compostilla and
Litoral de Almeria power plants, similar to that at the Los Barrios
station, whilst the Alcudia plant uses coals with a sulphur content of
less than 1%, which requires the use of a semi-dry system. The
Barranco de Tirajana and Granadilla plants use sea water.
   The plan also contemplates the installation of new
desulphurisation plants or the adaptation of ones that already exist
at the Compostilla and Litoral de Almeria power stations.
