  • modifications, rigid derivations and/or changes in the line with a total reduction of 6.2 km of the three-phase circuit;
  • disposal and/or joining of operating lines with a total decrease to 3 three-phase power lines for a total of 43.2 km;
  • partial restructuring of the grid south of Naples, with a total decrease to 1 three-phase line and 20.6 km;
  • entry into operation of 4 new lines for a total of 5.9 km: Torre Centrale-Torre Nord 150 kV, Siniscola 2-Buzzi Unicem 150 kV, Sarroch-Air Liquide 150 kV, CP Imperia-Imperia RFI 132 kV;
