Tyrrhenian Link Submarine Power Cable

under construction

The Tyrrhenian Link is a 1-GW bidirectional submarine power cable authorized by the Italian government in 2023 to connect Sardinia to Sicily and the Italian mainland. It aims to increase electricity exchange between the regions, bolster grid reliability, and help grid operators efficiently use more renewable energy. The cable uses high-voltage direct current (HVDC) technology with voltage source converter (VSC) technology, allowing it to move up to a gigawatt of power and reverse power flow nearly instantaneously. It also has black-start capability to help restore the grid in case of shutdowns. The western section between Sardinia and Sicily was completed in January, and the eastern section between Sicily and Campania was completed in April, setting a world record for power cable depth at 2,150 meters below sea level.
