was the first ever constructed in Queensland and the state's first use of steel towers for electricity distribution. The last of the four generating sets was installed by mid-1959. The power station's staff and families were provided accommodation in a small village, named Cardstone, located downstream from the plant.

Upgrade

The power station was upgraded between 2005 and 2008. This has effectively extended the life of the power station by 25 years and increased capacity, generation, efficiency and availability.
