Project Description
The Tarraleah Redevelopment Project is part of Hydro Tasmania’s Battery of the Nation initiative, aimed at upgrading the existing hydropower system to increase capacity and flexibility.

– A 12 km headrace tunnel and 4.2 km pipeline to convey water to the new power station.
– Installation of a 70m high surge tower to manage water pressure.
– New transmission corridor (16 km) to link with existing transmission lines.
– Construction workforce of up to 250 people, with a peak construction period of four years.
