The Parangana Power Station is a mini-hydro power station located in north-western Tasmania, Australia. It is located below the rock-filled/clay core Parangana Dam which forms Lake Parangana.^[2] It is the only mini hydro electric power station in the Mersey–Forth run-of-river scheme that also contains seven conventional hydroelectric power stations.

The power station was commissioned in 2002 by Hydro Tasmania. It has one Tyco Tamar Francis turbine, with a generating capacity of 0.85 megawatts (1,140 hp) of electricity.^[3]

Much of the water from Lake Parangana travels the approximately 8 km to the Lemonthyme Power Station which discharges into the River Forth, however some water is allowed to continue down the Mersey River for environmental reasons, after running through the Parangana mini hydro station.
