Powerhouse Ultimo

Built for Repurpose

The original Ultimo Power House, built in 1899 to provide electricity for Sydney's trams, includes four steam engine generators in the engine hall. Steam is the world’s primary industrial driver for more than 200 years, spanning the 1700–1900s.

On 11 October 1963, the Ultimo Power House closes. Large sections of its former Pump House are demolished in between 1967 and 1968 to allow for widening the William Henry Street Bridge.

In 1976, most of the Power House plant and equipment are removed. And in 1977, the Boiler House chimney stacks are demolished to below-roofline heights. The Boiler House, with fourteen boilers installed at the peak of capacity, is designed to produce high-pressure for conversion to electricity, and to use seawater taken from Darling Harbour to cool its condensers.
