About the project
The program of work in north-east Tasmania involved the redevelopment of the three substations that serve the area – Norwood, Scottsdale and Derby – and the construction of a new 110 kV transmission line between the substations to replace an existing 88 kV line. The old line had reached the end of it life and had no capacity to provide the load growth forecast for the region in coming years.
The new line now provides two 110 kV circuits between the Norwood and Scottsdale substations, with a single 110 kV circuit to the Derby Substation. The old 88 kV line and towers have now been removed. The redevelopment program represents a $50 million investment in the transmission system in the north-east.
The benefits
The redevelopment of the transmission system in the north-east has significantly strengthened the system and ensured there is sufficient capacity to meet the anticipated growth in demand for electricity in the region. It also provides for the future transmission of electricity generated from the proposed Musselroe Wind Farm to be constructed by Hydro Tasmania.
Completion date
The project was completed in mid-2007.
