Network upgrade benefits 6000 inner-city Brisbane homes and businesses

Energex has finished a $10 million upgrade to the Hamilton and Ascot electricity network in Brisbane, which will benefit more than 6000 homes and businesses in the local area.

The project involved major upgrades of Energex’s Hamilton Substation. The upgrade included the replacement of two 7.5MVA electricity transformers with two 25MVA transformers, more than tripling the power capacity to homes and businesses in parts of Ascot, Hamilton, Eagle Farm, Hendra, Newstead and Albion. The project also included the installation of a new underground power cable and replacing 3.4km of overhead powerlines in the local streets.

The upgrades will provide the improved reliability and increased power capacity allowing for future growth and increased local electricity use. Like most areas in South-East Queensland, the areas around Hamilton and Ascot have seen growth in population and commercial activity in the past decade, placing pressure on power supplies, especially at peak times.

There has also been a rapid uptake of power hungry appliances such as air-conditioners, with 75 per cent of all homes in the area now having at least one air-conditioner and close to 15 per cent having three or more systems.

Across the supply area of Hamilton Substation there are around 8000 air-conditioning systems installed in local homes and, according to the latest Queensland household energy survey, this is tipped to rise to nearly 11,000 systems within five years.
