Main works constructed
In 2009, the first cable of the SA.PE.I. – an undersea direct-current connection between Fiume Santo in Sardinia and Latina – was put into operation. Work on the second cable will continue throughout 2010. This is one of the most important strategic works planned by Terna to upgrade the national electric system. The undersea connection is about 420 kilometres long and lies up to 1,600 metres below sea level, the deepest in the world. The total investment involved amounts to more than €700 million.

In 2009, Terna also increased its transformation capacity by about 700 MVA and 300 MVAR and put more than 150 kilometres of new high-voltage lines into operation.

Main works awaiting authorisation
During 2009, Terna initiated the authorisation process for a number of important works, including the new Italy-France and Italy-Montenegro interconnection projects. In addition to the new lines that have started the authorisation process, there are those whose authorisation by the competent Authorities is in progress.

Main worksites
During 2009, Terna started work on the construction of the undersea-cable part of one the main development works: the 380-kVi “Sorgente-Rizziconi” connection, which will upgrade the 380-kV interconnection across the Strait of Messina between Sicily and Calabria.
