Submarine power cables are gaining a prominent role in sharing electricity between regions or different countries. Efficient transmission systems save energy, reduce pollution and secure power grids
The deepest submarine power cable in the world runs in the Tyrrhenian sea, 1,600 metres below sea level. It connects Sardinia with the Italian mainland. The project is called SA.PE.I and links the converter stations of Fiume Santo, near Sassari, and Latina.
