Electricity generation

According to initial estimates, in 2011 net domestic power generation (see table below) decreased slightly by 0.5% year on year. Analysing the various main sources of energy, net of ancillary services, thermal generation showed a 1.6% drop in 2011 compared with 2010.
In 2011, hydroelectric production reduced sharply with regard to 2010, recording a decrease of 11.4%, net of consumption for auxiliary services.

Once again, the net production from wind, solar and geothermal energy soared strongly in 2011 compared with the previous year, climbing by 51.1% overall.
