Tarraleah Hydro-electric Development, Derwent River

Background

This development, designed to utilize the water of the Derwent River and Lake St. Clair storage, was the first constructed by the Hydro Electric Commission.

It was augmented by the completion of Clark Dam in 1949 followed by Butlers Gorge Power Station, the second canal and the creation of the first pumped storage system.

It was the first 110 kV installation in the state. Tailrace water is now used in 6 downstream stations. It has provided reliable base loads since commissioning in 1938.
