Yingina / Great Lake
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.
Poatina Power Station
The station is underground on the northern side of Yingina / Great Lake. When Waddamana Power Station was decommissioned, Poatina replaced it in the broader power system. Poatina is ideally located, making use of a steep drop from Yingina / Great Lake down the face of the Great Western Tiers. Water that passes through Poatina is then used to generate energy at Trevallyn Power Station.

Tods Corner Power Station
Arthurs Lake was created to increase the water available at Yingina / Great Lake. Water is pumped from Arthurs Lake 140 m up to Yingina / Great Lake. This means more energy can be generated from water in Yingina / Great Lake via the large Poatina Power Station and then Trevallyn Power Station. Before the water reaches Yingina / Great Lake, it passes through Tods Corner Power Station to generate a small amount of energy.

Trevallyn Power Station
Trevallyn was the first power station built outside the Central Highlands region. It is 5 km away from the centre of Launceston in northern Tasmania. Lake Trevallyn has very little storage, so the power station makes use of the daily flow.
