Power generation

According to initial estimates, in 2010 net domestic power generation (see table below) increased by +1.9% year on year. Analysing the data for production, net of dispatching services, by the sources reveals a +1.1% rise in thermoelectric generation compared with 2009.
In 2010, hydroelectric production records a change of +0.6% on 2009, net of consumptions for auxiliary services. Wind and photovoltaic generation once again rose dramatically compared with the previous year, posting a +39.3% overall rise compared with 2009, spurred by growth in wind assessed at around +29.1%, and +136.5% growth in photovoltaic energy compared with the preceding year.
Geothermal energy production, finally, was more or less stationary, at +0.3% on last year.
