Introduction
Terna - Rete Elettrica Nazionale S.p.A. is the company responsible in Italy for electricity
transmission and dispatching on the extra high voltage and high voltage electricity grid throughout
the national territory. To guarantee service continuity and quality under safety conditions, Terna
must collect, instant by instant, all the data on the status of the power system. By processing these
data, indicators are then developed of the power system performance.
The publication “Provisional Data on Operation of the Italian Power System - 2011” summarizes
the figures.
The most significant events included in the publication refer to the increased electricity
consumption in 2011, equal to +0.6% compared to 2010, representing a positive variation for the
second consecutive year after the 2009 sharp drop (-5.7%). In 2011, electricity demand reached
332.3 billion kWh. 86.3% of this demand was covered by domestic production allocated for
consumption and the remaining part (13.7%) by the balance between imports and exports with
foreign countries which increased by 3.3% compared to 2010. The significant contribution to the
national electricity demand from renewable sources should be noted, which increased by 51.1%
compared to 2010.
In 2011, the highest electricity demand on the Italian electricity grid equaled 56,474 MW (+0.1%
compared to 2010), recorded on July 13 at 12:00 pm.
The following pages provide additional information on these and other aspects of the Italian power
system’s management and operation.

N.B. Net import/export balance excluding the Republic of San Marino and the Vatican City.
During the year, electricity demand reached 332.3 billion kWh, rising by 0.6% compared to 2010, with a positive monthly demand variation in
almost all months.
The net domestic production allocated for consumption registered a 0.1% increase. The variation in the balance of physical exchanges of electricity
with foreign countries was positive compared to the previous year (+3.3%).
In particular, production from renewable sources significantly increased: geothermal, wind and photovoltaic solar energy (+51.1%). Hydroelectric
(-11.4%) and geothermal (-1.6%) production decreased. Electricity imports from foreign countries registered an increase equal to 3.0%, while
exports decreased (-5.7%).

N.B. : Data are net of electricity consumed by auxiliary services and by pumping.
In 2011, the highest electricity demand on the national power system was equal to 56,474 MW, recorded on July 13 at 12:00 pm, higher by
0.1% compared to the 2010 peak (56,425 MW, June 16, 2010).
During the year, the monthly peak figures were essentially higher than those of the same months in the previous year, with some exceptions.

The monthly hydroelectric capability factors show a quite variable trend for all of 2011, with spring and summer that were positive, while the
remaining seasons registered a significant drop. In April, in particular, the monthly index registered its annual peak with 1.31 (1.57 in November 2010).
The yearly energy capability factor of 1.24 (ratio of the capability in the current year to the average multi-year reference value) was higher
compared to the same value in the previous year (1.23 in 2010).

EXCHANGES
DEMAND
The balance of physical exchanges of electricity mainly shows the energy flows among the various areas of the Italian power system. In
particular, it is necessary to note the high flows going from Lombardy towards central Italy.
Electricity exports from Sicily to the mainland through the 380 kV connection, provide for the safe operation of Sicily’s and Calabria’s power
systems.

* L’energia non fornita è l’energia non ritirata da clienti connessi su rete AAT-AT-MT a seguito di evento interruttivo con
disalimentazione di utenza.
The limit value of the maximum transfer capacity on the interconnected system with foreign countries (NTC) during the day (07:00am11:00pm) is represented by the red broken line, while the same limit value at night (11:00pm-06:00am) is represented by the blue broken line.
In particular, the maximum transfer capacity for the winter months ranged daily between 8,040 MW and 7,390 MW. During the summer months
(May-September 2011 excluding August) the range was between 6,890 MW and 6,390 MW. In August, the range was between 5,400 MW and
3,830 MW.

● The electricity supplied on the grid is the electricity to be injected into the grid for covering the net internal
consumption.
In the case of a national grid, it is equal to the sum of net electricity production and of electricity imported from foreign
countries, after deducting the electricity consumed for pumping and exports to neighboring countries.
● The trend variation is the percentage change with respect to the same month or period in the previous year.
● The net electricity production of a group of generation plants in a given period of time, is the sum of the amounts
of electricity injected into the grid.
● The electricity consumed for pumping is the electricity used for the sole purpose of pumping water and storing it
for subsequent electricity generation.
● Regional Areas: consist in one or more neighboring regions and are grouped as follows:
TURIN
: Piemonte - Liguria - Valle d’Aosta
MILAN
: Lombardia
VENICE
: Friuli Venezia Giulia - Veneto - Trentino Alto Adige
FLORENCE : Emilia Romagna - Toscana
ROME
: Lazio - Umbria - Abruzzo - Molise - Marche
NAPLES
: Campania - Puglia - Basilicata - Calabria
PALERMO
: Sicilia
CAGLIARI
: Sardegna
● The hydro electric energy capability factor is the ratio of the energy capability in a given period and the mean
energy capability in the same period.
The energy capability of a group of power plants in a given period is the maximum amount of electricity that all
inflows observed in the same period could generate under the most favorable conditions.
● Not supplied energy is energy that is not withdrawn by users connected to the EHV-HV-MV following an interruption
with outage.
