The Repulse Power Station is a traditional hydroelectric plant situated in Tasmania's Central Highlands region. It lies within the Lower River Derwent catchment area and is under the ownership and operation of Hydro Tasmania, playing a vital role in supplying renewable energy to the local electricity network.
Technical details
As the eighth facility in the series of eleven hydroelectric stations on the Derwent scheme, Repulse Power Station is positioned downstream of Lake Repulse. This reservoir is created by the concrete arched Repulse Dam spanning the Derwent River. The station's infrastructure comprises the dam itself, an intake structure equipped with a gate to halt water flow, a short penstock integrated into the dam, the power station building, generation machinery, and associated support systems.
Authorized by the Tasmanian Parliament in 1961 and brought into operation in 1967 by the Hydro Electric Corporation (TAS), now Hydro Tasmania, this power station utilizes a single Boving Kaplan-type turbine designed to generate . The turbine features a five-bladed runner enclosed within a concrete spiral casing, which is stabilized by pre-stressed cables passing through stay vanes that also contribute to the structural foundation. Notably, there is no inlet valve installed at this facility. Its annual energy production is approximately , which is delivered to the TasNetworks transmission system through two Siemens 11 kV/220 kV generator transformers linked to an external switchyard.
The water released from Repulse Power Station continues downstream into the River Derwent.
