Upgrade works progress

Upgrade works are progressing on the Tarraleah hydropower scheme. Hazell Bros Group have been busy on the excavation of the downstream tunnel entrance (technically called a portal) of the Lake King William tunnel. Construction of this 1km tunnel is set to start in early 2024. It will link the new intake at Lake King William to a future new conveyance that will feed water into Tarraleah Power Station.
