This ongoing feasibility study, is aimed to develop theNatural Gas reservoir discovered in this area ofMediterranean sea and lower the cost of electric energyin the two islands. Solution for the cable laying and forthe control of a real multiterminal HVDC link have to bestudied together with the cable and Converter stationmanufacturer.

Under detailed study:
•The best solution to manage the multiterminal load control(LCC vs VSC, advanced control techniques, etc.)
•Together with the main cable manufacturer studies are on-going to improve cable technology and laying techniques.
ConConConCon’ssss ProProProPro’ssssUncertainty on the time and on the real cable manufacturer interest in the development of the technology for this kind of application
