Memorandum of Understanding for modernisation of the high and very-high voltage networks in the area of Rome

The Memorandum of understanding for the modernisation of the high (150 kV) and very high (220 and 380 kV) electrical distribution networks was signed in March 2010, by the City of Rome (Mayor and Director of Public Works), Acea Distribuzione and the company Terna Rete Elettrica Nazionale (operator of the national transmission networks). The Memorandum was countersigned for acceptance by the Region of Lazio (Director of Environment and Inter-Community Cooperation), the Park of Veio Regional Agency, RomaNatura Regional Agency, and City of Rome Department of Environmental Policy, as Managing Agency for the Roman Littoral Nature Reserve.

The Memorandum describes a programme of interventions concerning numerous electrical lines and transformer and distribution stations, and sets out important objectives towards increasing the capacity of the electrical systems, improvement in reliability and integration of plants on the territory. It provides for construction of around 123 km of new overhead electrical lines and the demolition of almost 300 km of existing overhead lines, constructed over many decades and passing through 11 protected natural areas. These interventions achieve another important benefit, in energy savings deriving from reduced losses in transmission and transformation within the network, thanks to the new technical features of the plants compared to the existing ones.

In 2014, Acea Distribuzione developed the working plans for a number of project parts and carried out works, as follows:

  1. North Rome/Bufalotta line - Completed working plans for the overhead and underground lines; construction of the overhead liens will begin in 2015;
  2. North Rome/Prati Fiscali line - Completed the working plans and began construction, with completion expected in 2015.
  3. Flaminia/Cassia – Completed the working plans for the overhead part.
  4. Upgrading La Storta primary station – Began works, for completion in early 2015.

Other works are currently in start-up stage, or are in the process of evaluation of environmental impacts for the necessary Regional authorisations.
