Net electricity generation in 2010 amounted to 130,484
million kWh, an increase of 16,627 million kWh compared
with the previous year. Net power generation on the Iberian
peninsula rose by 6,711 million kWh in 2010: the
increase due to the change in the consolidation method
(12,369 million kWh) and greater nuclear generation
was only partially offset by the decline in thermal generation
(down 23.0%) and in wind generation, the latter
essentially attributable to the transfer of ECyR (now Enel
Contribution to gross thermal generation
Green Power España) to the Renewable Energy Division.
In addition, output increased in Latin America by 10,205
million kWh, essentially due to the change in the consolidation
method (10,556 million kWh). More specifically,
the increase in thermal generation as a result of the full
availability of the plants at Fortaleza (Brazil) and San Isidro
(Chile) was more than offset by the decline in hydroelectric
generation (down 10.6%) in Colombia and Chile due
to poorer water availability.
