The Lemonthyme Power Station is a run-of-the-river hydroelectric power station located in north-western Tasmania, Australia. It is the fourth station in the MerseyForth run-of-river scheme that comprises seven hydroelectric power stations and one mini-hydro station.
Technical details The Parangana Dam forms Lake Parangana by damming the Mersey River. Water from the lake is diverted west to Lemonthyme Power Station via a -long tunnel, followed by a single surface penstock. The water then runs through the power station, and is discharged into the River Forth, then down to Lake Cethana.
The power station was commissioned in 1969 by the Hydro Electric Corporation (TAS). It has one Fuji Francis turbine, with a generating capacity of of electricity. The station output, estimated to be annually, is fed to TasNetworks' transmission grid via two 3-phase 11 kV/220 kV Siemens generator transformers to the outdoor switchyard.
Although much of the water from Lake Parangana travels the approximately 8 km to the Lemonthyme Power Station (which discharges into the River Forth), some water is allowed to continue down the Mersey River for environmental reasons, after running through the Parangana mini hydro station.
