Hydro-electric power station

Two posts, from two visits with different content.

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.

Trevallyn Lake & dam is on the South Esk river, just up from the gorge. The water comes down a combination of tunnel & pipe to the power station, where it's divided into four streams.

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.

This is the part up against the wall. The intake valve?

And the middle part.

This is turbine #1

The black column on #3 is turning, which is why it's shiny.

And the same with #4

Next, the alternator floor.

The guide says these are just here for display now. They've been replaced by electric (electronic?) tools.

Up to the top floor, which I think are the generators.

 

 

The two at this end are the older ones (above turbines #1 and #2).

Inside.

Inside one of the cupboard things.
