Origin Energy was formed in February 2000, as a result of a demerger of the Australian conglomerate, Boral Limited, which saw the energy business formed as a new company, separate from the building and construction materials business. The SAGASCO business became part of Origin Energy as part of the demerger.
Between 2001 and 2002, Origin acquired the Victorian electricity network suppliers Powercor and CitiPower. In 2004, the SEAGas pipeline was completed and commissioned, which served to link the Victorian and South Australian gas markets. During this time, Origin obtained 50% interest in the Kupe Gas Field, and managed to obtain Edison Mission Energy's 51.4% interest in New Zealand's Contact Energy. Origin sold its 53% shareholding in Contact Energy to the market in 2015.
On 27 November 2006 the Queensland Government announced the sale of Sun Retail Pty Ltd, the former retailing arm of Energex to Origin for $1.202 billion. Sun Retail included some 840,000 residential, commercial and industrial electricity customer accounts and 55,000 LPG customers.
On 15 December 2010, Origin Energy announced that it would purchase the retail divisions of Country Energy and Integral Energy from the Government of New South Wales, at a total cost of A$3.25 billion, as well as entering a GenTrader agreement with Eraring Energy (in which Origin supplies fuel, pays certain charges, and can dispatch and sell electricity output, while Eraring Energy owns, operates and maintains the power stations). The transaction was completed on 1 March 2011.
The company has a diverse exploration portfolio, which includes the Bowen, Surat and Cooper / Eromanga basins in Central Australia, the Otway and Bass basins in Southern Australia, as well as interests in the Perth Basin and Browse Basin in Western Australia, and the Bonaparte Basin in the Northern Territory. Outside Australia, Origin operates the Kupe gas field in the Taranaki Basin of New Zealand. The company also holds interests in New Zealand’s Canterbury Basin, and further afield, has interests in permits in Botswana and Vietnam.
Origin Energy is a major shareholder together with US giant ConocoPhillips and China's Sinopec in a joint venture of Australia Pacific LNG (APLNG), that delivers Australia's largest coal seam gas (CSG) to liquefied natural gas (LNG) export project in Queensland.
The project consists of:
On 26 October 2017, gas producer and exporter APLNG entered into a sales agreement with Origin Energy, to supply 41 petajoules of gas under a 14-month contract starting 1 November, significantly boosting the supply of natural gas to the domestic east coast market. The contract brings the company's total commitment to 186 PJ for 2018, representing almost 30% of Australian east coast domestic gas market demand.
As Australia's largest energy retailer, Origin has approximately 4.217 million customers, servicing both large energy customers and the residential and small business market. Product and service offerings include electricity, natural gas and LPG. Origin is also Australia’s leading provider of low-carbon products such as GreenPower, Green Gas and solar PV.
Origin operates one of Australia's largest power generation portfolios with 6,010 MW of capacity. This represents approximately 13 per cent of power generation capacity in the National Electricity Market.
