Overview
Origin Energy is an Australian integrated energy company headquartered in Sydney and listed on the Australian Securities Exchange. Its principal activities are electricity generation, electricity and natural-gas retailing, energy services, and participation in upstream gas and liquefied natural gas projects. The company serves residential customers, small businesses, large commercial and industrial users, and wholesale energy markets. Origin was created on 18 February 2000 through the demerger of energy assets from Boral. The separation brought the South Australian Gas Company, then known as SAGASCO, into the new business and gave Origin an initial platform in gas distribution, retailing, and energy infrastructure. During its early expansion, Origin acquired electricity retail licences in Victoria and developed gas-market infrastructure, including an interest in the SEAGas pipeline linking South Australia and Victoria. It also expanded into New Zealand through a substantial interest in Contact Energy, although that investment was later sold. The company enlarged its Australian retail footprint through major transactions with state-owned utilities. In 2006 it agreed to acquire Sun Retail, the former retail arm of Queensland’s Energex. In 2010 it agreed to purchase the retail businesses of Country Energy and Integral Energy from the New South Wales government. That transaction, completed in 2011, materially increased Origin’s customer base and strengthened its position in the National Electricity Market. Origin has since remained one of Australia’s largest energy retailers, supplying electricity and gas to millions of customers and offering products such as standard and market-linked energy plans, solar systems, batteries, and other household energy services. Origin also owns and contracts generation capacity across coal, gas, and renewable technologies. Its generation portfolio has included Eraring Power Station in New South Wales, described as Australia’s largest coal-fired power station, as well as gas-fired and renewable generation assets. Eraring has been scheduled for closure in 2029, subject to relevant arrangements and conditions. The company has stated that it intends to pursue emissions reduction and announced a goal of reaching net-zero direct and indirect emissions by 2050. Its strategy has nevertheless involved balancing decarbonisation, reliability of electricity supply, wholesale-market conditions, and investor returns. Reference material has noted a plan to reduce the extent of direct ownership of wind and solar assets while continuing to participate in renewable energy and customer energy solutions. Gas has been another important part of Origin’s business. The company has held interests in Queensland’s Bowen and Surat basins and participated in Australia Pacific LNG, a project involving gas-field development, a long transmission pipeline, and an LNG export terminal on Curtis Island in Queensland. Origin’s conventional upstream oil and gas subsidiary, Lattice Energy, was sold to Beach Energy in 2017. Origin has also been involved in exploration in the Beetaloo Basin in the Northern Territory, but divested from those projects in 2022 after exploration and hydraulic-fracturing activity had attracted environmental, community, and regulatory scrutiny. In late 2022, a consortium led by Brookfield Asset Management and EIG Global Energy Partners proposed an approximately A$18 billion takeover. Origin’s board agreed to the proposal in 2023, with the proposed structure separating the energy-market business from the integrated-gas business. The Australian Competition and Consumer Commission approved the transaction, but shareholders did not provide the required level of support. The proposal therefore ended in December 2023 after opposition led by major investor AustralianSuper. Origin’s public profile has also been shaped by compliance and environmental controversies. Regulators have fined the company over misleading explanations of Victorian electricity price increases and over prohibited exit fees charged to customers. In 2022 it was fined for hardship-program failures and pleaded guilty in Queensland over the release of polluted water associated with coal-seam-gas operations. These events have contributed to scrutiny of the company’s customer practices, environmental controls, and governance. Despite those issues, Origin remains an active major participant in Australia’s electricity and gas markets, combining retail operations, generation, energy technology, and selected gas-project interests.
History
Origin Energy was established on 18 February 2000 when Boral separated its energy interests into a new listed company. The demerger included SAGASCO, the former South Australian Gas Company, giving Origin an early presence in gas supply and distribution. The new company developed as an integrated energy business rather than as a pure electricity retailer, combining retail activities with generation, gas infrastructure, and upstream interests. Between 2001 and 2002, Origin obtained Victorian electricity retail licences from Powercor and CitiPower. The company also expanded its gas position through participation in the SEAGas pipeline, completed in 2004, which connected the Victorian and South Australian gas markets. Around the same period, Origin acquired a 50 percent interest in the Kupe gas field and took a 51.4 percent interest in New Zealand electricity company Contact Energy. Origin eventually sold its Contact Energy shareholding to the market in 2015. Origin’s Australian retail scale grew through state-asset transactions. In November 2006, the Queensland government announced the sale of Sun Retail, formerly Energex’s retail arm, to Origin for A$1.202 billion. In December 2010, Origin agreed to purchase the retail divisions of Country Energy and Integral Energy from the New South Wales government for a combined A$3.25 billion. The transaction closed on 1 March 2011 and was accompanied by a GenTrader arrangement involving Eraring Energy. Under that arrangement, Origin supplied fuel, paid certain charges, and controlled the dispatch and sale of electricity output, while Eraring Energy retained ownership and operational responsibility for its power stations. The company subsequently operated a broad generation portfolio and became a major participant in Australia’s National Electricity Market. Its assets and contracted positions included coal-fired generation, gas-fired generation, and renewable energy. Eraring Power Station in New South Wales became a particularly important asset and has been described as Australia’s largest coal-fired power station. Origin has planned for Eraring to close in 2029, reflecting the changing economics and policy environment for coal generation while raising questions about reliability, replacement capacity, and the pace of the energy transition. Gas and LNG have remained significant to Origin’s history. The company held interests in gas resources in Queensland’s Bowen and Surat basins and participated in Australia Pacific LNG with ConocoPhillips and Sinopec. The APLNG development linked upstream gas fields to a 530-kilometre pipeline and an LNG export facility on Curtis Island. Origin also explored unconventional gas opportunities in the Beetaloo Basin in the Northern Territory. The Northern Territory government approved hydraulic-fracturing activity in 2019, drilling began later that year, and fracturing commenced in 2020 after a pandemic-related suspension. Community and environmental concerns focused on groundwater, consultation with traditional landowners, and the adequacy of safeguards. Origin divested from the Beetaloo projects in 2022. In 2017, Origin sold Lattice Energy and its conventional upstream oil and gas business to Beach Energy for A$1.585 billion. The disposal narrowed Origin’s direct upstream exposure while leaving it with important gas and LNG interests through arrangements such as Australia Pacific LNG. In the retail business, Origin continued serving residential, small-business, commercial, and industrial customers and expanded its offering to include solar, batteries, and other energy-management services. Customer and environmental compliance became recurring issues in the late 2010s and early 2020s. A former compliance manager alleged in 2017 that Origin had failed to address well-integrity problems and had fostered a culture of bullying and harassment; the company denied the allegations. In 2020, the ACCC took action over a Victorian customer communication that gave a misleading explanation for an electricity price increase. In 2021, the company was fined for charging prohibited exit fees despite having received complaints and reviewed relevant contract templates. In 2022, Origin was fined for hardship-program breaches and pleaded guilty over a polluted-water release from Queensland coal-seam-gas operations. Origin announced a 2050 net-zero goal in 2022. Its transition strategy has involved reducing emissions, supporting renewable and customer-energy solutions, and managing the continued role of dispatchable generation and gas. Reference material has also described a plan to minimise direct ownership of wind and solar assets in pursuit of investor returns, illustrating the tension between asset ownership, capital discipline, and decarbonisation. The company became the subject of a major takeover proposal in November 2022, when Brookfield Asset Management and EIG Global Energy Partners offered approximately A$18 billion. Origin agreed to the proposal in March 2023. The proposed transaction would have placed the energy-market business with Brookfield and its partners, while EIG’s MidOcean Energy would have acquired the integrated-gas business. The ACCC approved the transaction in October 2023, but the deal required 75 percent shareholder support. That threshold was not achieved after opposition from AustralianSuper and other shareholders, and the takeover was terminated in December 2023. Origin consequently remained an independent listed Australian energy company.
