City of Melbourne | C37
Substation J is one of a number of electricity zone substations located in the Melbourne CBD. It was originally built to distribute electricity from the adjacent Spencer Street Power Station. While the power station was demolished in 2007, substation J continues to provide power to adjacent streets through four 22kV/6.6kV transformers. The power station has been replaced by Upper West Side residential apartments, however there are reminders of the former use of the site such as the control room, which was decommissioned in 1982 but remains largely intact, and the heritage-protected cast-iron water tank, which was installed in 1927. This tank was part of a hydraulic power system that pumped pressurised water from the Yarra River through pipes to operate the CBD’s lifts and wool presses. The former Spencer Street Power Station was believed to be linked to the Yarra River and other parts of the city by underground canals. One tunnel, built in 1915, ran from the Power Station all the way underneath Spencer Street down to the site now occupied by the Melbourne Aquarium.
