The Galetta facility near Almonte, Ontario was built in 1907. At that time, it used two 400 kilowatt horizontal synchronous Westinghouse generators.

Since then, the generators have been re-wound and uprated to 600 kilowatts. Two 175 kilowatt vertical propeller turbines with induction generators were added, and the original turbines were replaced with new, larger machines. During the summer of 1999, the control room was rebuilt with vacuum switchgear and an automatic control system.

While more than a century old, with these updates, Galetta will continue producing clean energy for decades to come.

The Galetta facility currently generates an average of 6,500 megawatt hours each year.

TransAlta owns and operates the Galetta facility through its wholly owned subsidiary Canadian Hydro Developers.
