ENDESA Subsidiary, SNET, Has Invested over Euro 5 Million in Environmental Improvements at its Provence Plant

ENDESA (NYSE: ELE):

   --  This investment will extend the useful life of the plant,
        improve health and safety conditions on the site and enhance
        the quality of the environment in its surroundings.

   --  The operation forms part of SNET's Plan for the Environment
        and Sustainable Development initiated several years ago and
        which has been reinforced since ENDESA acquired a stake in the
        French group.

   Since 2000 ENDESA (NYSE: ELE) subsidiary SNET has invested over
Euro 5 million in a variety of measures designed to reduce noise
pollution and particle emissions.
   The investment will extend the useful life of the plant, improve
health and safety conditions on the site and enhance the quality of
the environment in its surroundings.
   The measures, which will continue into 2006, are part of SNET's
Plan for the Environment and Sustainable Development initiated several
years ago and which has been reinforced since ENDESA acquired a stake
in the French group.

   Measures implemented to reduce noise pollution

   In 2002 a campaign was carried out to measure noise levels in the
areas surrounding the plant and a study made to determine the source
of this noise. As a result of this study, the 2005-2006 Action Plan
was drawn up, with a budget of Euro 1.2 million. The aim of the plan
is to treat the main sources of noise pollution at the main and
auxiliary power facilities.
   As part of this investment, on September 2, 2005 a silencer was
installed on the roof of the boiler in a spectacular helicopter
operation in order to reduce the noise produced by steam traps.
   Also, several measures have been implemented to reduce noise in
the plant's groups, mainly by improving the performance of the
silencers on the steam taps and replacing steam ejectors with steam
pumps.

   Measures implemented to reduce dust particles

   Several measures have been implemented to treat dust particles so
treating emissions at source. These include:
   In 2002 a device was installed to measure dust particles around
the coal store - this device had an eight point scale.
   Thirteen industrial water cannons were also installed to ensure
the surface irrigation of most of the coal store. Also, semi automatic
sprinklers have been installed all along the plant's road network at a
cost of Euro 202,000. The irrigation of the coal store will be fully
automatic by the end of 2005.
   A new underground unloading bay for trucks with water sprinkling
systems has also been installed in the coal store. This started
operating on September 1, 2005, and cost Euro 2.2 million. Another
hopper is to be constructed underneath the building completing the
truck unloading facility by early 2006 at a cost of Euro 505,000.
   In April 2005 a high pressure sprinkler system was installed at a
cost of Euro 90, 000 designed to prevent the dust produced by the
bucket wheel excavator from rising.
   The vehicles and road network within the plant have also been
thoroughly cleaned. Now all tanker trucks transporting power plant ash
are washed before leaving the area. In January 2005 a facility was
constructed to wash the wheels and chassis of all trucks leaving the
coal store.
   Lastly, the frequency with which the road network is cleaned
varies according to climate conditions with an annual cost of Euro
80,000.
