The Electricity Commission of New South Wales, sometimes called Elcom, was a statutory authority responsible for electricity generation and its bulk transmission throughout New South Wales, Australia. The Commission was established on 22 May 1950 by the Electricity Commission Act 1950 to take control of power generation in the State. The Commission acquired the power stations and main transmission lines of the four major supply authorities: Southern Electricity Supply, Sydney County Council, the Department of Railways and the Electric Light and Power Supply Corporation Ltd, known as the Balmain Electric Light Company, to acquire the Balmain Power Station. The Commission was responsible for the centralised co-ordination of electricity generation and transmission in the State, and some local councils continued to be distributors of electricity only.
The Electricity Commission of New South Wales was formed in 1950 to take over and manage electricity generation across the state, as part of the post-war reconstruction. Until then, power generation and distribution in the state involved a variety of authorities, the four major ones being Southern Electricity Supply, Sydney County Council, the Government Railways and the Electric Light and Power Supply Corporation Ltd, known as the Balmain Electric Light Company. Between 1936 and 1952, Sydney County Council was responsible for electricity generation and distribution in the City of Sydney, and operated the Bunnerong and Pyrmont Power Stations until they were transferred to the Electricity Commission in 1952. From the Government Railways the Electricity Commission in 1953 acquired the White Bay Power Station. From the Balmain Electric Light Company, the Electricity Commission acquired the Balmain Power Station.
