Trevallyn Power Station was built 1955, and replaced Duck Reach. It's managed by Hydro Tasmania. A few years back, the state-owned HEC was broken up into 3 companies: the Hydro, who generate the power; Transend, who transmit it, and Aurora, who deal with the consumer side.
First, the 1950s style control room. Mostly replaced now by a couple of PCs.
The next stop is right down on the turbine floor
There are four of these, but only #4 and #3 were operating.
Next, the alternator floor.
The guide says these are just here for display now. They've been replaced by electric (electronic?) tools.
The two at this end are the older ones (above turbines #1 and #2).
