Our History

We have a long history in the energy sector, starting with the establishment of the Electricity Commission of NSW in the 1950s to the inception of TransGrid in 1995. 

Against the backdrop of a changing energy landscape, we have developed our network over the past 70 years to meet the growing needs of consumers in NSW and the ACT. In 2015, TransGrid became a private company when the NSW Government granted NSW Electricity Networks a 99-year lease over the NSW transmission network.  


The Electricity Commission of New South Wales was formed on 22 May 1950 as the statutory body responsible for the generation of electricity and its bulk transmission throughout NSW. This centralised the coordination of the state’s electricity generation and supply. 

1950s to 60s

During this period, the NSW Electricity Commission more than trebled its power capacity from 490MW to 1800MW.

Early 1990s 

The Australian Government began to deregulate state owned monopolies to promote competition, consumer choice and potentially cheaper electricity.


The NSW Electricity Commission adopted the trading name Pacific Power.


As deregulation continued, the high voltage electricity transmission network assets were separated from Pacific Power, and on 1 February 1995 a new organisation was formed: TransGrid. The power stations were divided to form two new companies – Delta Electricity and Macquarie Generation (both later sold to Energy Australia and AGL respectively).


The NEM started to operate. The Council of Australian Governments (COAG) set up three market bodies to oversee the nation’s energy markets.


The Australian Energy Regulator (AER) and the Australian Energy Market Commission (AEMC) were established.


The Australian Energy Market Operator (AEMO) was created to take responsibility for gas and electricity market operations.


A consortium, NSW Electricity Networks, successfully bid $10.3 billion for a 99-year lease of TransGrid’s transmission network.


TransGrid Services (TGS) was established to provide connections for renewable generation, telecommunications and other contestable services for our customers.
