The State Electricity Commission of Victoria (SEC, SECV, or ECV) is a government-owned electricity company operating in Victoria, Australia. Originally created to harness the state's brown coal resources for power generation, the SEC progressively established a dominant position within Victoria's electricity sector before its disaggregation and privatisation in the 1990s. Reestablished in 2023, it currently focuses on investments in renewable energy and energy storage markets.
In 1918, legislation passed by the Victorian Parliament led to the appointment of a board known as the Electricity Commissioners tasked with investigating the utilisation of brown coal deposits located in the Latrobe Valley. Subsequently renamed as the SEC, the organisation constructed power plants at Yallourn, expanded its operations into electricity distribution and retailing, and acquired regulatory oversight of Victoria’s electricity industry. By the 1970s, it had secured an almost complete monopoly over the state’s electrical supply system. During the early 1990s, its assets were corporatised and privatised, while regulatory responsibilities were reassigned to separate authorities. A residual body was retained to manage remaining assets and government-supported contracts.
In the course of the 2022 Victorian state election, the Victorian Labor Party under the leadership of Daniel Andrews committed to reviving SEC as an active participant within the deregulated National Electricity Market. Following Labor’s electoral success, a budget allocation of $1 billion for 2023–24 was designated to establish SEC Victoria. Legislative changes enacted in 2024 embedded its role into the Victorian Constitution as a renewable energy provider and imposed stringent conditions preventing its dissolution or privatisation without approval by a parliamentary supermajority.
Background
Initial efforts in electricity generation primarily served public lighting and electric tram systems, with supply provided by either municipal authorities or private firms operating under council franchises.
Prior to SECV's establishment, electricity generation and distribution were carried out by a variety of private companies and municipal bodies. The Melbourne City Council managed Spencer Street Power Station from 1892, supplying both local residents and wholesale municipal distributors. The Melbourne Electric Supply Company, founded in 1899 under long-term franchise agreements, operated power stations at Richmond and Geelong. Additionally, Victorian Railways ran Newport Power Station to provide electricity for Melbourne’s suburban train network. These facilities relied heavily on coal sourced from New South Wales’ black coal mines, which were frequently affected by industrial disputes.
Victoria’s abundant brown coal deposits in the Latrobe Valley presented an alternative energy resource. Although brown coal’s high moisture content made transportation impractical over long distances, improvements in electrical transmission technology permitted power generation close to fuel sources with distribution extended to consumers.
Formation
Following a 1911 study trip abroad, engineer Herbert Reah Harper recognised the potential of Victoria’s brown coal inspired by Germany’s utilisation and recommended establishing a public utility similar to Ontario Hydro. Harper was appointed to the Victorian Government Brown Coal Advisory Committee chaired by Hyman Herman. The committee’s 1917 report advocated creating an Electricity Commission responsible for developing brown coal reserves alongside constructing power generation facilities and transmission lines. In December 1918, Parliament enacted legislation establishing a Commission endowed with regulatory and investigative authority, including enforcement powers under the Electric Light and Power Act, which governed electricity generation and distribution.
The Victorian Electricity Commissioners were created in 1919 through the Electricity Commissioners Act 1918, taking over administrative functions from the Public Works Department. On 10 January 1921, this body was reconstituted as the State Electricity Commission of Victoria (SECV) under the State Electricity Commission Act 1920. Sir John Monash served as chairman and general manager, while Harper held the position of chief engineer until 1936.
Capital infrastructure
The SECV’s first significant undertaking was the construction of the 50 MW Yallourn Power Station, accompanied by a briquette manufacturing facility and an open-cut brown coal mine located in the Latrobe Valley. This project received funding of $2.86 million following recommendations made in 1917. Transmission of electricity to Melbourne commenced in 1924, covering a distance of 160 km via a 132 kV line, which was subsequently upgraded to 220 kV in 1956 and further enhanced to 500 kV by 1970. Additionally, the SECV developed the Newport 'B' Power Station in 1923, which operated on imported black coal and Yallourn briquettes, supplying Melbourne until Yallourn became operational.
Hydroelectric ventures began in 1922 with the Rubicon Hydroelectric Scheme situated northeast of Melbourne, contributing approximately 16.9% of SECV’s electricity output during its initial ten years. The Kiewa Hydroelectric Scheme received approval in 1937 but its progress was postponed due to World War II.
Organisational framework
The legislation granted the SECV authority to license competing entities and to acquire private companies once their franchises expired. By 1953, SECV had taken control of several major operations, including:
- North Melbourne Electric Tramway & Lighting Company (1922)
- Melbourne Electric Supply Company (1930)
- Electric Supply Company of Victoria (1934)
- Newport B Power Station from Victorian Railways (1939)
- Melbourne City Council Spencer Street Power Station (1941)
- Newport A Power Station from Victorian Railways (1951)
- Mildura Electrical Undertaking (1953)
Throughout the 1920s and 1930s, SECV also consolidated numerous smaller municipal electricity providers. The purchase of Melbourne Electric Supply Company incorporated their tramway services in Geelong, followed by acquisition of the Electric Supply Company of Victoria, which operated tram networks in Ballarat and Bendigo. Despite these integrations, eleven inner Melbourne municipalities retained independent Municipal Electricity Undertakings (MEUs) until the sector’s privatisation in the 1990s. These MEUs served areas such as Melbourne, Footscray, Brunswick, Box Hill, Port Melbourne, Preston, Northcote, Heidelberg, Coburg, Doncaster & Templestowe, and Williamstown. Other local councils procured electricity wholesale from private firms that also managed distribution networks and, in some cases, early electric tramways like those found in Essendon.
Tariff strategy
The SECV established electricity prices, setting tariffs that varied according to town size based on supply expenses. In 1928, rural councils petitioned for tariff equalisation; however, the Labor Government declined this request. Such equalisation was only achieved in 1965, initiated by the SECV itself rather than due to political influence.
Expansion
Following World War II, SECV increased its generation capacity to satisfy growing electricity demand. Larger 50 MW generators replaced smaller pre-war units at Yallourn and Newport power stations, while hydroelectric development persisted at both Eildon and the Kiewa. Richmond Power Station transitioned to oil fuel, and smaller prefabricated plants were introduced in Geelong and Ballarat, reducing reliance on black coal by the mid-1950s.
The 1960s witnessed further capacity enhancements with installation of 120 MW generators at Yallourn and commissioning of Hazelwood Power Station’s eight units of 200 MW each, alongside a new open-cut mine and briquette plant. However, Morwell coal proved unsuitable for briquette production, necessitating coal transport from Yallourn.
By the late 1960s, brown coal from SECV-operated open cut mines accounted for 90% of Victoria’s electricity supply. This reliance on domestic coal insulated SECV from the oil price shocks experienced globally during the 1970s.
Latrobe Valley development continued throughout the 1970s with upgrades at Yallourn W plant employing advanced Japanese and German technology to modernise older units. A proposed gas-fired power station at Newport encountered significant public resistance and eventually opened during the 1980s at half its originally planned capacity.
In the 1980s, construction commenced on the Loy Yang open cut mine intended to fuel two new power stations—Loy Yang A and B—featuring a total of eight units rated at 500 MW each sharing a common mine. This project faced cost overruns attributed to excessive labor expenses, poor management decisions, overinvestment, and workforce redundancies, prompting a government review in 1982.
Mounting debt from rapid expansion combined with increased dividend requirements led to higher electricity prices for consumers during this decade. Furthermore, SECV’s participation in the Portland Smelter Contract granted Alcoa discounted electricity rates at the cost of other customers.
Closure
The Kirner Labor administration commenced the SECV's privatisation process in 1991. By April 1992, Mission Energy Australia Pty Ltd acquired a 51 percent share in Loy Yang B. The Kennett government intensified the privatisation efforts in 1994 by dismantling the SECV into five distribution and retail companies (which incorporated MEUs), five generation firms, and a transmission company. Between 1995 and 1999, these entities, alongside other state-owned utilities such as the Gas and Fuel Corporation of Victoria, underwent corporatisation and subsequent privatisation.
Ownership of the Victorian Power Exchange (VPX), the wholesale market operator, remained with the State Government. This organisation was later restructured: responsibilities for market and system operations were transferred to the National Electricity Market Management Company (NEMMCO), while transmission planning duties moved to VENCorp, now known as the Australian Energy Markets Operator (AEMO).
Additional Functions
In addition to electricity production, the SECV also:
- Established and managed Yallourn, a company town for power station employees.
- Manufactured briquettes from brown coal at both Yallourn and Morwell facilities.
- Ran a 900mm gauge electric railway initially at Yallourn, later extended to Morwell and Hazelwood, primarily for coal transportation.
- Maintained a dedicated fire and rescue service—termed "SECV Fire Rescue" post-1984—with staffed stations operating around the clock at Yallourn, Morwell, and Loy Yang sites. This unit utilized specialized firefighting apparatus and trained personnel in industrial firefighting, hazardous materials handling, motor vehicle extrication, high-angle rescue, confined space operations, and high-voltage emergency response. A formal agreement with the Country Fire Authority enabled deployment beyond SECV properties when necessary.
- Operated six diesel shunting locomotives servicing rail sidings at Yallourn, Morwell, and Newport Powerhouse locations.
- Managed and expanded regional electric tram networks in Ballarat, Bendigo, and Geelong following acquisitions of earlier electricity supply companies such as ESCo and MESC.
Shell Entity (1994–2023)
Following restructuring, the SECV continued as a diminished state-owned company overseen by an executive committee. It retained debt obligations linked to HRL Limited’s brown coal gasification project and provided electricity to the Portland aluminium smelter through Vicpower Trading. The Point Henry aluminium smelter was also supplied until its closure in July 2016.
Regulatory responsibilities transitioned to Victoria’s Essential Services Commission for retail electricity distributors and to the Australian Energy Regulator for distribution networks, transmission infrastructure, and wholesale market oversight.
Successor Electricity Distributors in Victoria
After privatisation in the 1990s, principal retail electricity distributors included:
- United Energy
- Solaris Energy (later merged with Australian Gas Light Company)
- Powercor Australia
- CitiPower
- Eastern Energy
By March 2020, electricity distribution across Victoria was managed by:
- CitiPower
- Jemena
- Powercor Australia
- AusNet Services
- United Energy
Each distributor operates within defined geographic boundaries.
Revival (2023–)
Prior to the 2022 Victorian state election, Premier Daniel Andrews pledged to reinstate the State Electricity Commission (SEC) if his government remained in power. The reestablished SEC is designed to make direct investments in renewable energy and storage initiatives, supporting Victoria’s goal of achieving 95% renewable electricity by 2035 and reaching net zero emissions by 2045. The government intends to maintain a majority ownership, holding 51% of these renewable ventures.
Andrews further promised constitutional safeguards to ensure the SEC remains publicly owned, mandating a special parliamentary majority of 60% for any future moves toward privatisation—mirroring the protections already in place for water utilities.
In the Victorian budget for 2023/24, $1 billion was dedicated to the SEC to facilitate the development of 4.5 gigawatts of renewable energy capacity. The commission has since opened offices in Morwell and Melbourne, appointed an interim CEO, and established an expert advisory board, although member Alan Finkel stepped down in June 2023.
The SEC initiated an expression of interest process for its first wave of renewable projects, drawing more than 100 proposals that collectively represent 30 GW of energy storage and 24 GW of new renewable capacity. These projects align with plans to decommission the Loy Yang A coal-fired power station between 2028 and 2030. A comprehensive ten-year strategic roadmap for the SEC is anticipated by the close of 2023.
State-owned company
In October 2023, newly appointed Premier Jacinta Allan unveiled the SEC’s decade-long strategy. Allan disclosed that the SEC would function as an energy retailer, initially focusing on industrial and commercial sectors. Additionally, the SEC plans to pilot household electrification programs and expand Victoria’s renewable energy workforce through the SEC Centre of Training Excellence, targeting training for 6,000 apprentices and trainees. The revitalised SEC operates as a state-owned enterprise under the name SEC Victoria Pty Ltd, managed by a CEO and board in accordance with the Commonwealth Corporations Act 2001.
In April 2024, Simon Corbell, former deputy chief minister of the Australian Capital Territory, was named chairman of the SEC board.
