Waddamana-Lindisfarne 220kV transmission line

About the project

With demand across southern Tasmania increasing, a project to construct a second 220kV injection point is currently being implemented. This involves the construction of a new double circuit 220 kV transmission line between the Waddamana substation and the Lindisfarne substation, together with the installation of two 220 kV/110 kV network transformers at the Lindisfarne substation. The old 110 kV transmission line between Waddamana and Bridgewater was dismantled to enable the new line to be built in the same corridor. The estimated total cost of the project is $130 million.

The benefits

When completed, the project will provide a more secure transmission supply to Hobart and southern Tasmania and reinforce the current low capacity supply to Hobart's eastern shore. It will also reduce our reliance on the Chapel Street substation, as well as reducing the load transferred through the transmission lines connected to Chapel Street substation and through the Chapel Street-Risdon 110kV transmission line.

Completion date

The project is scheduled to be completed by end of March 2011.

Information on the Approval Process

The Waddamana to Risdon Vale project was subject to a comprehensive assessment process under the Major Infrastructure Development Approvals Act (MIDA). Subsequent to this approval, a short detour of the line was required in order to avoid an area of Aboriginal cultural heritage. This detour was approved by Southern Midlands Council under the Land Use Planning and Approvals Act (LUPA).
