(1) The figure for 2012 reflects a more accurate determination of amounts.

Net electricity generation by the Division in 2013 amounted to 132,427 million kWh, a decrease of 8,081 million kWh compared with 2012.

More specifically, in 2013, net electricity generation in the Iberian peninsula decreased by 7,696 million kWh (-9.9%) as a result of the decline in conventional thermal generation (-23.8%), reflecting the fall in demand and the improvement in the water conditions in which the Division’s hydroelectric plants operated. In Latin America, net electricity generation posted a net decrease of 307 million kWh, mainly as a result of lower hydroelectric generation associated with drought conditions over the entire area, only partially offset by the increase in thermal output in Brazil and Chile, the latter following the entry into service of the Bocamina II plant.

Enel Open Data

Gross thermal generation by the Division in 2013 amounted to 95,241 million kWh, a decrease of 10,771 million kWh compared with the previous year (-10.2%). The decline was attributable to lower coal and gas generation in Spain as a result of the developments in net generation noted above. In Latin America, natural gas generation by the Fortaleza plant increased, and there was also an increase in coal generation as a result of the entry into service of the Bocamina II plant.

At December 31, 2013, the size of the electricity distribution network of the Iberia and Latin America Division had increased by 2,607 km, with the change mainly concentrated in the South American countries.

Energy transported in 2013 amounted to 159,968 million kWh, a decrease of 1,163 million kWh, reflecting the decline in demand in the Iberian Peninsula, which was only partially offset by the rise in demand in Latin America, notable in Brazil and Chile.

Electricity sales to end users in 2013 totaled 157,635 million kWh, a decrease of 4,855 million kWh compared with 2012. The reduction in amounts sold in the Iberian peninsula (-6,642 million kWh) as a result of the continuing recession was only partly offset by an increase in sales in Latin America (+1,787 million kWh) caused by the increase in electricity demand in the area, especially in Brazil and Chile.
