The Electricity Commission of New South Wales, commonly known as Elcom, functioned as a statutory authority responsible for managing electricity generation and bulk transmission throughout New South Wales, Australia. Established on 22 May 1950 under the Electricity Commission Act 1950, it unified power production by acquiring assets from four key providers: Southern Electricity Supply, Sydney County Council, the Department of Railways, and the Electric Light and Power Supply Corporation Ltd (also known as Balmain Electric Light Company), which owned the Balmain Power Station. While the commission oversaw generation and transmission statewide, certain local councils continued to operate as electricity distributors.
Creation and growth
The commission was created in 1950 to oversee electricity generation across the state during the period of post-war rebuilding. It absorbed operations formerly managed by several entities, including Southern Electricity Supply, Sydney County Council, NSWGR, and the Balmain Electric Light Company. Until 1952, Sydney County Council handled both generation and distribution within the City of Sydney, operating facilities such as Bunnerong Power Station and Pyrmont Power Station before transferring these assets to Elcom. In 1953, Elcom took ownership of White Bay Power Station from NSWGR and acquired Balmain Power Station through the Balmain Electric Light Company Purchase Act 1950.
From 1950 to 1960, Elcom expanded New South Wales’ electricity capacity more than threefold—from 490 megawatts to 1800 megawatts. This expansion involved upgrading existing plants like Bunnerong, White Bay, Balmain, and Pyrmont, alongside constructing new power stations designed by NSWGR: Tallawarra Power Station near Port Kembla (1954), Wangi Power Station at Lake Macquarie (1956), and Wallerawang Power Station close to Lithgow (1957).
Reorganization of distribution
After generation responsibilities shifted to the Electricity Commission, Sydney County Council (SCC) and other municipal county councils transitioned exclusively into electricity distribution roles. Prospect County Council was formed in 1957 as a division from SCC.
During the early 1990s, eastern Australian states prepared for the introduction of the National Electricity Market and deregulation initiatives. In 1989, the state government established Sydney Electricity to take over distribution duties previously held by Sydney’s municipal councils. Prospect County Council evolved into Prospect Electricity in 1991, managing electricity retail services in Greater Western Sydney under local council jurisdiction. In 1996, Sydney Electricity merged with Orion Energy to create EnergyAustralia. That same year saw Prospect Electricity combine with Illawarra Electricity, resulting in the formation of Integral Energy. On 1 July 2001, rural NSW retailers Great Southern Energy, Advance Energy, and Northpower merged to form Country Energy.
On 14 December 2010, under the Kristina Keneally Labor government, New South Wales sold its electricity retail assets for A$5.3 billion. The transactions included:
- Acquisition by Origin Energy of Integral Energy, Country Energy’s retail arm (including its branding), and electricity trading rights connected to Eraring Energy for $3.25 billion. The remaining Country Energy operations were rebranded as Essential Energy on 1 March 2011. Integral Energy and Country Energy now operate as subsidiaries under Origin.
- Purchase by Hong Kong-listed TRUenergy of the retail business formerly owned by government-run EnergyAustralia—including its name, output trading rights from Delta Electricity power stations located west of Sydney, and three development sites—for $2.035 billion. TRUenergy also pledged $240 million toward capital improvements at Wallerawang power station. On 2 March 2011, the state government renamed its remaining government-controlled EnergyAustralia entity as Ausgrid, while TRUenergy rebranded itself as EnergyAustralia in 2012.
Restructuring and Reestablishment
During the early 1990s, Australian state governments initiated deregulation of state-owned monopoly electricity commissions with the goals of fostering competition, expanding consumer choice, and potentially reducing costs. In 1992, the Electricity Commission adopted the trading name Pacific Power and underwent corporatisation by 1995.
That same year, Pacific Power’s coal mining operations were spun off into a separate government entity called ELCOM Collieries (Powercoal). In 2002, Centennial Coal purchased Powercoal for $306 million, emerging as the state's largest independent coal supplier for electricity generation. Subsequently, in 2010, Thailand-based Banpu acquired Centennial Coal for US$2 billion, with Powercoal continuing as its subsidiary. Centennial operates five coal mines, exporting roughly 40% of its production while supplying fuel for about 40% of New South Wales’ coal-fired power plants.
The high-voltage transmission system was divested in 1995 to form TransGrid. The Terranora interconnector (Directlink), launched in 2000 to link the New South Wales and Queensland electricity grids, was established as a joint venture between NorthPower (later Country Energy), TransÉnergie (a Hydro-Québec subsidiary), and Fonds de solidarité FTQ. A second interconnection, the Queensland – New South Wales Interconnector, commenced operation in 2002 and is managed jointly by TransGrid and Powerlink Queensland. In 2007, Australian Pipeline Trust (part of APA Group) acquired Directlink for US$133 million. By 2008, ownership transitioned to Energy Infrastructure Investments Group (EII), with APA retaining operational control; EII's ownership is divided among APA (19.9%), Japan-based Marubeni (49.9%), and Osaka Gas (30.2%).
In 1996, two new generation companies were created: Delta Electricity and Macquarie Generation. By 2000, remaining power stations were transferred to Eraring Energy, while Pacific Power International’s consulting division was sold to Connell Wagner. Pacific Power was officially dissolved in 2003.
Privatisation
The process of privatising the State's electricity assets began in 1997 and remained a contentious issue well into the new century.
On 14 December 2010, the Labor government led by Kristina Keneally completed the initial phase of partial privatisation for $5.3 billion. In January 2011, eight directors from Delta Electricity resigned in opposition to proposed sales of trading rights. Amid criticism and a lack of interested buyers, the Government halted further privatisation efforts. The Keneally Labor administration suffered a significant defeat at the 2011 New South Wales state election, experiencing a swing exceeding 16%.
In May 2012, the Liberal government under O'Farrell passed legislation authorising the sale of State-owned generators. Subsequently, in July 2013, EnergyAustralia purchased Wallerawang and Mount Piper power stations from Delta Electricity for A$160 million. Due to declining demand, elevated operating costs, and coal supply challenges, EnergyAustralia permanently shut down Wallerawang in November 2014. In September 2014, Macquarie Generation—including Bayswater and Liddell power stations—was sold to AGL Energy for $1.505 billion. AGL announced intentions to retire Liddell Power Station by 2022. The final Delta Electricity asset, Vales Point Power Station (with a capacity of 1,320 MW), was sold in November 2015 to Sunset Power International for $1 million.
During the 2015 New South Wales state election, the Liberal government led by Mike Baird campaigned on leasing a 49% stake in the state-owned electricity distribution network ("poles and wires") for a term of 99 years. This proposal included full leasing of the high-voltage distributor TransGrid and majority ownership stakes in Ausgrid and Endeavour Energy, excluding rural Essential Energy. While Labor and trade unions opposed privatisation plans, several business organizations—such as the Energy Users' Association, Business Council of Australia, Australian Industry Group, Infrastructure Partnerships Australia, and Tourism and Transport Forum—expressed support. Prominent Labor figures including former Prime Minister Paul Keating also endorsed the initiative. Full privatisation received backing from Australia's Productivity Commission. Despite this broad support from various sectors, public opinion polls indicated weak approval.
In December 2015, the NSW Electricity Networks consortium secured a 99-year lease for TransGrid's transmission assets at $10.3 billion. Then in October 2016, Australian-based investors IFM Investors and AustralianSuper acquired a 50.4% stake in Ausgrid's similar lease arrangement for $16 billion. By June 2017, an Australian-led consortium comprising Macquarie Infrastructure and Real Assets (MIRA), AMP Capital, British Columbia Investment Management Corporation, and Qatar Investment Authority purchased a 50.4% interest in Endeavour Energy's network assets under comparable long-term lease terms.
