Crossing the divide

The Basslink HVDC interconnector consists of a monopolar metallic return scheme, with a rated DC voltage of 400 kV, a rated DC current of 1250 A and a rated continuous power of 500 MW defined at the DC terminal of the rectifier converter station. It is the world´s longest submarine HVDC cable project, linking Tasmania with the Australian mainline and providing efficient two-way power transfers. It has a dynamic power transfer capacity up to 626 MW from Tasmania to Victoria to meet Victorian peak load demands. Basslink provides an interconnection between energy-constrained hydro generation in Tasmania and the capacity-constrained predominantly thermal generation in Victoria monopolar metallic return scheme
