For more than a century, our power stations have electrified Tasmania. We’re working to generate clean, reliable electricity today and for generations to come.
Butlers Gorge Power Station
The power station is supplied by the water stored at Lake King William. Water then flows to Tarraleah Power Station.

Francis hydropower
Nieterana mini-hydro
Nieterana is the Aboriginal name for little brother. This mini-hydro station sits alongside ‘big sibling’ Butlers Gorge Power Station and was commissioned in 2004.
When additional turbines were added to Tarraleah Power Station, a second canal needed to be built to carry enough water from Lake King William to make full use of all turbines. Nieterana was built at the base of Lake King William to make use of the water flowing through the second canal.

Francis hydropower
Tarraleah Power Station
Water flows from Butlers Gorge Power Station via a series of tunnels, canals and pipes to Tarraleah. The water drops 290 m through penstocks (steel pipes) to the power station. The water from the station meets with water from Tungatinah Power Station and flows to Lake Liapootah.

What's happening at Tarraleah?
What's happening at Tarraleah?
The iconic Tarraleah hydropower scheme is reaching the end of its operational life. We’re planning to redevelop it to deliver more energy and flexible capacity, while retaining iconic heritage elements. We’ll modernise how water is transported and build a new, bigger station, so the scheme can generate more energy when it’s most needed and most valued.
Tungatinah Power Station
Water is brought together from various lakes and lagoons to Tungatinah Power Station through natural and built systems. Once through the station, the water flow meets with water from Tarraleah and flows to Lake Liapootah.
1953–56
142.2 MW

Liapootah Power Station
This is the first power station in the lower run-of-river system and is where the cascade effect begins. Water from Lake Liapootah runs through to Liapootah Power Station and continues to Wayatinah Lagoon.
