Production

Electricity generation takes place through a number of technologies which exploit conventional and renewable energy sources. Enel produces electricity in 23 countries with a balanced mix of sources, in which renewable ones (hydro, wind, geothermal, biomass, photovoltaic, etc.) play a major role and fossil fuels are diversified among coal, oil, and gas (simple and combined-cycle).

Total Group net efficient power as of December 31, 2010 amounted to 97,281 MW. Our generation plants produced more than 290.2 TWh of net electric energy in 2010 (an increase of 8.4% with respect to the previous year), of which 81.6 TWh were produced in Italy and 208.6 TWh were produced abroad.
In Italy, the Enel Group’s power plants produced 81.6 TWh compared to 84.0 TWh in 2009 (-2.9%). The decrease in the quantity produced regards mainly thermal and hydro production (-2.4 TWh and -0.3 TWh, respectively), and was partially offset by the increase in wind production (+0.2 TWh).
The Enel Group’s total net production abroad amounted to 208.6 TWh, an increase of 24.8 TWh with respect to 2009 (+13.5%), which was mainly due to the larger contribution by Endesa (+16.6 TWh), among other things because of a change in the method of consolidation that took place in 2009, but had its full effect in 2010 (5). Additional contributions to the increase came from the Russian generation company Enel OGK-5 (+3.7 TWh), the companies in Bulgaria (+0.9 TWh), and Slovenské elektrárne in Slovakia (+1.1 TWh).
