The document includes all useful information on Edison's activities and financial highlights.

1. Overview
Founded in 1884, Edison is Europe’s oldest energy company. Today, it’s the second energy company
in Italy and a European leading operator with operations in the supply, production and sales of
electric power and hydrocarbons (natural gas and crude oil).
Edison has operations and activities in 10 countries in Europe, Africa and Middle East employing about
4,000 people.
In 2011 Edison was confirmed by Fortune magazine as one of “Most Admired Companies” in Italy and
worldwide in the energy industry.
Electric power
Edison has 11.5% share of the Italian electricity production with 33.2 TWh produced in 2011. Between
2001 and 2008 the company completed one of Europe’s largest investment plans in power generation
by building new highly efficient and eco-friendly plants powered by gas for 7.000 MW. Today, it has an
installed capacity of 11.5 GW thanks to a generation fleet of 72 hydro plants, 28 thermoelectric plants,
32 wind plants, 9 solar plants and 1 biomass plant.
In the electric power generation, Edison aims at growing on the foreign markets and in the area of
renewable energy sources. This strategy will enable the Group to diversify the geographic presence of
its electric power operations and its mix of generating facilities. In Greece, through ElpEdison (Joint
Venture with Hellenic Petroleum), Edison is the second largest electricity company in the country.
Greek activities include an operative 390 MW CCGT power plant in Thessaloniki, a 420 MW CCGT
facility in Thisvi and other generation projects in the study phase.
Hydrocarbons
The company has an integrated presence in the hydrocarbons sector from production to importation,
distribution and sale of natural gas and crude oil. With 15.2 billion cubic metres of gas sales in 2011,
the company covered 19.6% of the Italian gas demand. The Group has hydrocarbons reserves of 49.8
billion cubic metres, thanks to 60 concessions and permits in Italy and 23 outside Italy. Edison has also
3 gas storage centres.
Hydrocarbons exploration and production activities in North Africa and other high potential areas will
play a key role in the next years, with the objective of increasing reserves and annual production. Most
of the E&P investments will focus on the proved reserves of Abu Qir in Egypt, a concession Edison won
in 2009. Abu Qir fields produce about 1.5 billion cubic meters of natural gas and 1.5 million barrels of
liquids a year.
Outside Italy, Edison holds 23 licenses for Exploration & Production activities. Production activities are
taking place in Egypt and the British sector of the North Sea. Development activities are located in
Croatia and Algeria. Edison holds exploration licenses also in Norway, Iran and Ivory Coast.
Gas infrastructures
Edison is playing a leading role in the development of new infrastructures to import natural gas for
Europe and Italy. The Rovigo regasification terminal in Italy, the first offshore facility of this kind in
the world, became operational in 2009 being able to import 8 billion cubic meters of natural gas a year,

2. equal to 10% of Italy’s natural gas needs. Two other important projects under development are the
Galsi gas pipeline (8 billion cubic meters of natural gas a year), which will link Algeria with Sardinia
and Tuscany, and the ITGI gas pipeline (10 billion cubic meters of natural gas a year), which will link
Italy and Europe with the Caspian Sea region through Greece and Turkey.
Italian market
In 2008, Edison entered the Italian residential market with a sales package to supply electric power to
families. A year later, Edison broadened its sales package for families with the addition of natural gas.
In 2010 Edison achieved the milestone of one million customers served in Italy.
International presence
Edison and its subsidiaries operate across Europe (Italy, Greece, UK, Norway, Croatia, Bulgaria,
Romania, Hungary, Belgium, Turkey), Africa (Ivory Coast, Algeria), Middle East (Egypt).
