 Three small obsolete power stations generated energy for trams and electricity for Ithaca and Toowong and the supply for all other suburbs was purchased in bulk from CEL under 10 year agreements.The 1920s and 1930s was a period of tramways expansion following the BCC acquisition of the tramways system from the Brisbane Tramways Trust in 1925.In 1926 the Greater Brisbane Council, anxious to control the city's electricity supply, decided to build its own powerhouse at New Farm, under the supervision of the BCC Tramways Department.
