(Tiper Stock Exchange) – Triadmanager of electricity transmission networks listed on Euronext Milan, obtained theformal agreement of the Region of Sardinia For three important interventions which will make it possible to increase the efficiency of the regional and national electricity grid, while promoting the development and integration of energy produced from renewable sources: the Tyrrhenian Link – West Branch; the SACOI 3 and the new 150 kV cable connection CP Terra Mala.
The company speaks of one “decisive step” which starts the final stage of the authorization process of the three works in progress at the Ministry of the Environment and Energy Security, the result of the fruitful institutional collaboration between Terna and the Sardinia Region.
Specifically, the Tyrrhenian Link – West Branch, is the approximately 480 km section of the 3.7 billion euro submarine power line that will connect Sicily and Sardinia. From the landfall of the cable in Terra Mala, in the province of Cagliari, the underground cables will mainly travel along already existing roads for about 30 km, leaving the environment and landscape unaltered, up to Selargius, where the conversion station will be built in areas adjacent to the already existing electrical station. The Sardinian Municipalities involved in the passage of the underground cable, all falling within the metropolitan area of Cagliari, are: Maracalagonis, Quartucciu, Quartu Sant’Elena, Settimo San Pietro and Sinnai.
The SACOI3 is the new 200 kV electrical connection that will renew the current marine cable between Sardinia, Corsica and mainland Italy using modern technologies. The intervention, for which Terna will invest 950 million euros, is aimed at guaranteeing greater stability and reliability of the electricity system, at improving the quality of the service, the efficiency of the grid and the integration of renewable sources. The project includes a converter station located adjacent to the existing Codrongianos electrical station; two terrestrial cables at the landing place of the marine cables in Santa Teresa di Gallura and two marine cables connecting Sardinia (landing point of Santa Teresa di Gallura) and Corsica.
There 150 kV connection of CP Terra Mala provides for a new underground cable of approximately 3 km connecting the existing Quartucciu-Villasimius power line and the future Primary substation owned by the local distributor. The intervention will make it possible to increase the mesh of the electricity grid in the Cagliari area, or to increase the quality of the energy transmission service in the area.
