Preliminary Data for the First Nine Months of 2005; ENDESA Raises Its Global Power Output by 5.3%

ENDESA (NYSE:ELE):

   --  Growth in generation in Europe of 43.3% underpinned the sharp
        rise in production.

   --  The company produced a total of 136,956 GWh in the first nine
        months of 2005, of which 69,697 GWh were in Spain, a decrease
        of 3.7% on the previous year mostly due to the drought.

   --  Generation at ENDESA's CCGTs increased by 20% to September
        2005 and now contributes 18% of the Group's global output.

   --  Roughly half of the total energy ENDESA generated was outside
        Spain.

   ENDESA produced a total de 136,956 GWh in the first nine months of
2005, an increase of 5.3% from the same period last year. Growth came
primarily in the areas outside of Spain where ENDESA generates power,
with increases of 43.3% in Europe and 5.4% in Latin America. In Spain,
output between January and September reached 69,697 GWh, 3.7% lower
than in the year-ago period. Roughly half of the total energy
generated by ENDESA at present comes from outside Spain.
   By technology, ENDESA's CCGTs generated 20% more in 9M05 (24,707
GWh) and its coal-fired plants 17.7% more (42,108 GWh). ENDESA's hydro
output (36,435 GWh) was slightly lower (-0.3%) owing to the scant
level of rainfall in Spain during the period. In Spain, ENDESA's hydro
production was down 30% through September, far below the average
decline in the industry of approximately 40%.
   The low rainfall led to a sharp increase in fuel-powered
generation in Spain, although globally this type of production
decreased 5.9% to 15,357 GWh. Nuclear generation decreased 14% (to
16,761 GWh) while renewable/CHP output rose 15.3% (to 1,588 GWh).
   ENDESA boasts a balanced production mix: 27% of GWh produced at
all its plants is hydro based, 31% is coal, 12% is nuclear, 11%
fuel-oil/gas, 18% is from CCGTs and 1% from renewables/CHP.
   This balanced mix provides ENDESA with stable generation in
different scenarios, making it less vulnerable to hydro volatility in
the mainland or to swings in oil and gas prices.

   Spain

   ENDESA produced 69,697 GWh of power in Spain in the first nine
months of 2005, a decrease of 3.7% on the same period of 2004. Power
output totalled 57,734 GWh in the ordinary mainland system -a 5.5%
decrease- and 10,394 GWh in the Balearic and Canary Islands and
Ceuta-Melilla systems -an increase of 5.2%-. Energy produced via CCGTs
and renewables/CHP rose 14.2% (to 1.569 GWh) and via wind power by
41%.
   ENDESA's hydro output in Spain was down 30% yoy at 6,086 GWh owing
to the low level of rainfall so far this year.
   The rest of ENDESA's technologies recorded mixed performances.
Generation by the coal plants (29,737 GWh) was largely unchanged from
9M04, while generation by the CCGTs (5,641 GWh) increased by 25%.
Nuclear generation (16,761 GWh) fell by 14%, due mainly to the
shutdown of the Vandellos II plant for several months. Net output from
fuel plants stood at 9,903 GWh, an 18% increase.

   Latin America

   ENDESA produced 42,869 GWh of power in Latin America through to
September this year, 5.4% more than in the same period last year.
Driving this growth was the recovery of demand in Argentina and Peru,
which resulted in a sharp increase in those countries' energy needs,
as well as increased production in Chile. ENDESA's output in Argentina
rose 3.2% to 12,046 GWh and in Peru by 23.2% to 5,061 GWh. Also
noteworthy was the 14% increase in generation in Chile (to 13,778
GWh). Production fell by 1.8% in Colombia to 8,855 GWh and by 17.3% in
Brazil to 3,130 GWh due to the lack of gas.

   Europe

   ENDESA posted a substantial 43.3% rise in production in Europe to
24,390 GWh, driven in part by the consolidation of French generator
Snet, over which ENDESA secured control at the beginning of September
last year.
   Production in Italy through to September totalled 17,309 GWh, 9%
higher than the 15,872 GWh produced in the first nine months of 2004.
Behind this sharp increase was the start-up of CCGT production
(generation using this technology rose 91% in 9M05 to 8,322 GWh),
while hydro output in Italy fell 2.5% to 1,819 GWh. Coal-fired output
rose 7.4% to 4,402 GWh, while fuel-oil production fell 50% to 2,747
GWh. ENDESA produced 19 GWh of wind power in Italy in the period.
   Snet's output in the first nine months of 2005 was 7,081 GWh.
