What new infrastructure is being proposed as part of this project and how big will it be?

The project will include approximately 190km of new transmission line infrastructure between Bulgana and Sydenham, a new terminal station to the north of Ballarat and several minor electricity infrastructure upgrades across western Victoria. The new infrastructure to be built as part of the project will include:

A new terminal station to the north of Ballarat with two new 1,000MVA 500/220kV transformers
A new 220kV double circuit transmission line from the Bulgana Terminal Station to the new terminal station, via the Waubra Terminal Station
A new 500kV double circuit transmission line from the Sydenham Terminal Station to the new terminal station
Upgrades to existing transmission infrastructure.

The typical size of a 220kV transmission tower is approximately 55m high and 12m wide. The typical size of a 500kV transmission tower is approximately 72m high and 16m wide.
