The Anthony Dam is a concrete-faced rock-fill embankment dam across the Anthony River, located in the West Coast region of Tasmania, Australia. Completed in 1993, the resultant reservoir, Lake Plimsoll, was established for the purpose of generation of hydroelectricity via the below-ground Tribute Power Station, a conventional hydroelectric power station. The dam, its reservoir, and the power station are owned and operated by Hydro Tasmania.
Dam and reservoir overview The concrete-face rockfill dam wall is high and long. When full, Lake Plimsoll has capacity of and covers , drawn from a catchment area of . The uncontrolled spillway has a flow capacity of .
Located adjacent to the main concrete-faced dam is the off-stream Anthony Levee, an earth core rock-fill saddle embankment that is high and long. The levee also impounds Lake Plimsoll.
Hydroelectric power station The Tribute Power Station is part of the Anthony Power Development scheme (which is part of the Pieman Power Development scheme). The proposed Anthony scheme comprised four hydroelectric power stations and five dams. However, due to political and legal considerations due to the Franklin Dam controversy, not all the dams or power stations were completed.
The Tribute Power Station is the first station in the scheme, being the highest upstream, yet the most-recent major hydro-electric power development completed in Tasmania. Located underground within the main dam wall, the power station receives water from the lake via a headrace tunnel.
The power station was commissioned in 1994 by the Hydro Electric Corporation (TAS), in the aftermath of the Franklin Dam controversy, and the station has one Fuji Francis-type turbine, with a generating capacity of of electricity. The station output, estimated to be annually, is fed to TasNetworks' transmission grid via a 13.8 kV/220 kV Fuji surface generator transformer to the outdoor switchyard.
Announced in 2008, the 1,000 GWH Project resulted in upgrades to component parts of existing superstructure operated by Hydro Tasmania.
