Transmission

High Voltage Direct Current (HVDC) transmission: a way of carrying electricity over long distances and underwater.

Dedicated transmission lines will transport the power from the power plant in Tunisia to the European grid via a landing point in Italy, just North of Rome. The TuNur transmission links for the two phases of the project are as follows:

Phase 1
  • To transport the electricity from Tunisia to Europe, a terrestrial transmission link with a length of ca. 400 km will be built from the power plant site to Tunisia’s Northern coast.
  • A dedicated 250 MW subsea cable will transport the electricity ca. 400-500 km to a high-capacity interconnection point in Malta.
  • From there the  power will be transferred through the existing Malta-Sicily cable into the Italian grid and then on to other European countries such as the Germany, France, Belgium and the UK.
Phase 2
  • To transport the electricity from Tunisia to Europe, a terrestrial transmission link with a length of ca. 450 km will be built from the power plant site to Tunisia’s Northern coast.
  • A subsea cable will transport the electricity ca. 600 km to a high-capacity interconnection point in Central Italy, North of Rome.
  • From this interconnection point the electricity can be fed into the European grid without encountering bottlenecks.
