 By 1933 an additional substation was urgently required at Kedron in order to relieve a serious overload being carried every afternoon by the substation at Windsor, where the 500 kW mercury arc rectifier plant was carrying 700 volts.Council minutes suggest that provision for this new substation should have been made two or three years prior to 1933, but that the expenditure was delayed for financial reasons until it became essential for safety.On 29 May 1934 the council authorised purchase of an allotment facing Kedron Brook Road and adjoining the Kedron Park Hotel for the purpose of constructing a tramway substation.
