Electricity transmission

Our transmission system consists of a 220 kV and a 110 kV transmission network that connects generators to the distribution system, major industrial customers and the undersea cable, Basslink. It's an intricate system of 3688 circuit kilometres of transmission lines, 48 substations and eight switching stations as well as a telecommunications system and control centre.

In many instances, the generating load is located at remote sites, which requires extensive transmission infrastructure crossing difficult terrain and environmentally sensitive areas, including World Heritage.

Main load centres are connected to the 220 kV transmission system at Burnie, Lindisfarne and Chapel Street (Hobart), George Town, Hadspen (Launceston) and Sheffield substations. Other load centres are connected via the 110 kV peripheral transmission system.
