A network of Brisbane tramways substations, supplied from the Brisbane Powerhouse, were developed by Brisbane City Council after they took over the Brisbane Tramways system from Brisbane Tramways Company (BTCo). The new powerhouse and substations were needed, as BTCo had not adequately invested enough into the electricity network to keep the system running efficiently. Brisbane City Council maintained this electricity network from 1927 until 1969, when the decision was made not to have Trams in Brisbane, and the network was shut down and decommissioned.
