Marinus Link comprises high voltage direct current (HVDC) cables, fibre optic cables, and converter stations in both Tasmania and Victoria.

The cables will be about 345 kilometres long, including 255 kilometres of undersea cables across Bass Strait and 90 kilometres of underground cables in Victoria.  

Marinus Link will be delivered in two stages. Initially as a 750 megawatt (MW) project (Stage 1) with a second 750 MW link to follow at a later date (Stage 2).
