Electricity System

Electricity business

Based on preliminary figures, Italian electricity demand for 2009 came to 317,602 GWh, a decline of 6.4% from the previous year (see table below).
During the year, 86% of the demand for electricity on the network was met by domestic power generation (88.2% in 2008), for a total of 273,153 GWh, net of consumption by ancillary services and pumping, for a decrease of 26,294 GWh (-9%) from 2008. The remaining portion of demand (14%) was covered by net imports, for a total of 44,449 GWh, compared with 40,034 GWh for the previous year (+11%).

Power generation

According to initial estimates, in 2009 net domestic power generation (see table below) decreased by 9.2% year on year.
Breaking down the figures for generation by source, net of ancillary services, we see a decline in thermal power generation for the year of 13.7% from 2008.
In 2009, hydroelectric production rose by a significant 9.5% compared with 2008, after taking into account consumption for ancillary services.

The annual hydroelectric production index exceeded the figures recorded for the preceding year, rising to 1.03 compared with 0.91 in 2008.

Energy demand in Italy

In 2009, according to preliminary figures, domestic energy demand amounted to 317,602 GWh, a decline of 6.4% from 2008. In order to compare 2009 figures with those of the previous year, a number of factors need to be considered. First of all, there is the variation in the calendar. Although there are fewer total days than the previous year (2008 was a leap year so there were 366 days), there was one more business day in 2009. Secondly, weather conditions were different.

Terna’s National Control Centre and the electricity system’s safety

Terna’s National Control Centre is the heart of the national electricity system and is located in the outskirts of Rome. The central control room carries out a detailed control of the country’s entire electricity transmission grid. Sophisticated monitoring and management systems allow Terna to control, instant by instant, the electricity produced in Italy or imported from other countries and to safely manage the energy flows.
