ENDESA (NYSE: ELE):

   --  The plant is being connected to the grid for the first time,
        upgrading the city's existing network.

   --  Investment in the 400 MW CCGT totalled Euro 218 million.

   --  ENDESA operates six CCGTs in Spain and total installed
        capacity between the mainland and islands stands at 1,854 MW.
        Another 1,906 MW of capacity will be added from the five CCGTs
        currently being built by the company.

   ENDESA (NYSE: ELE) has connected the 400 MW Huelva CCGT to the
grid for the first time, upgrading the city's existing network. The
total budget for this plant stands at around Euro 218 million.
   Output reached around 20 MW in this first synchronisation to the
network, which marks the start of tests at different loads that will
be carried out until the plant begins operating commercially. This
will happen once quality and reliability tests have concluded and the
plant has run for 100 hours at full throttle.
   When the CCGT begins commercial operations it will replace the
capacity of the plant's existing fuel and fuel-oil/gas gas groups.
This will provide huge environment-related benefits and greater
guarantees of supply for the city of Huelva and the area surrounding
the plant, as well as a substantial boost to the plant's productivity.
   In Spain, ENDESA has six CCGTs in operation between the mainland
and islands with a capacity of 1,854 MW. Another 1,906 MW of capacity
will be added from the five CCGTs currently being built by the
company: two on the mainland, which will contribute 1,205 MW, and
three on the islands, which will contribute a combined 701 MW. Endesa
will construct a total of 3,200 MW over the 2006-2009 period,
situating it in the vanguard in our country in the development of a
technology that will make a significant contribution to reducing
greenhouse gas emissions and improving energy efficiency.
