In 2012, Terna increased its transformation capacity by about 10,500 MVA(1) of power and put more than 30 km of new High and Very High Voltage lines into operation.

The main works completed during 2012 were the following:

  • installation of PST (Phase Shifting Transformers) in the 380 kV electricity stations of Foggia and Villanova, to optimize energy flows on the H&VHV grid of the Centre - South;
  • the new 220 kV underground cable power lines “Pellerina – Levanna”, “Pellerina - Turin West”, “Pellerina – Martinetto” and electricity station in SF6 of Pellerina (Rat. 220 kV city of Turin);
  • installation of 285 MVAr, 380 kV reactances at the 380 kV electricity stations of Scandale, Aurelia, Montalto, Santa Sofia and Feroleto;
  • expansion of the 150 kV section of the 380 kV electricity station of Brindisi Sud;
  • construction of the 380/150 kV electricity station of Castellaneta, inserted in input-output on the “Matera – Taranto” 380 kV line;
  • construction of the 380/150 kV electricity station of Aliano and the associated connections to the H&VHV grid (150 kV in underground cable connections are being installed);
  • as regards the Sorgente – Rizziconi 380 kV connection, the first stage of the work was completed in the 380 kV electricity station of Scilla, in Calabria, with the commissioning of the 150 kV section and of the HV cable connections to the NTG;
  • in relation to plants designed to collect and use energy production from renewable sources in the South, important 380 kV and 150 kV electricity stations were built, numerous limitations of long stretches of the 150 kV grid were removed and numerous minor projects were carried out.
