The National Electricity Market (NEM) is an arrangement in Australia's electricity sector for the connection of the electricity transmission grids of the eastern and southern Australia states and territories to create a cross-state wholesale electricity market. The Australian Energy Market Commission develops and maintains the Australian National Electricity Rules (NER), which have the force of law in the states and territories participating in NEM. The Rules are enforced by the Australian Energy Regulator. The day-to-day management of NEM is performed by the Australian Energy Market Operator.
EnergyAustralia is an electricity generation, electricity and gas retailing private company in Australia. It is one of the "big three" retailers in the National Electricity Market. It generates electricity primarily using coal fired generation, at the Yallourn Power Station in Victoria, and the Mount Piper Power Station in New South Wales. 10% of its generation is from wind power, 32% from gas, and 58% from coal. It is Australia's second biggest emitter of greenhouse gases, after AGL Energy. As a loss making company in 2023, its parent in Hong Kong, CLP Group, has stated that it is looking for partners for renewable energy investment, however as of this time, there were no plans to build new renewable energy itself.
Alinta Limited was an Australian energy infrastructure company. It has grown from a small, Western Australia-based gas distributor and retailer to the largest energy infrastructure company in Australia. It was bought in 2007 by a consortium including Singapore Power and various parties which include the now defunct Babcock & Brown funds.
The Bell Bay Power Station was a power station located in Bell Bay, on the Tamar River, Tasmania, Australia, adjacent to the Tamar Valley Power Station, with which it was often confused. It was commissioned between 1971 and 1974 as an oil fired thermal power station, and was converted to natural gas in 2003, after the commissioning of the Tasmanian Gas Pipeline, a submarine gas pipeline which transports natural gas from Longford, Victoria, under Bass Strait, to Bell Bay, Tasmania. As the power station's primary role was to provide system security in the event of drought for Tasmania's predominantly hydro-electric based generation system it only was rarely called on to operate, resulting in intervals of five to eight years between periods of significant use. After the commissioning of Basslink in 2006, the power station was decommissioned in 2009.
Mica Creek Power Station is located 5 km south of Mount Isa in north-west Queensland, Australia. It was natural gas powered with 12 turbines of various sizes that generate a combined capacity of 318 MW of electricity. The power station is owned by state government owned Stanwell Corporation.
AGL Energy Ltd is an Australian listed public company involved in both the generation and retailing of electricity and gas for residential and commercial use. AGL is Australia's largest electricity generator, and the nation's largest carbon emitter. In 2022, 83% of its energy came from burning coal. It produces more emissions as a single company than the nations of New Zealand, Portugal or Sweden, according to its largest shareholder, Mike Cannon-Brookes, who named it "one of the most toxic companies on the planet".
Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal, historically, was the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood power station which supplied around 20% of Victoria's electricity, and to a lesser extent with the exit of Anglesea power station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world.
The Electricity Commission of New South Wales, sometimes called Elcom, was a statutory authority responsible for electricity generation and its bulk transmission throughout New South Wales, Australia. The commission was established on 22 May 1950 by the Electricity Commission Act 1950 to take control of power generation in the State. The commission acquired the power stations and main transmission lines of the four major supply authorities: Southern Electricity Supply, Sydney County Council, the Department of Railways and the Electric Light and Power Supply Corporation Ltd, also known as the Balmain Electric Light Company, the owner and operator of Balmain Power Station. The commission was responsible for the centralised co-ordination of electricity generation and transmission in the State, and some local councils continued to be distributors of electricity only.
Queensland's energy policy is based on the year 2000 document called the Queensland Energy Policy: A Cleaner Energy Strategy. The Queensland Government assists energy development through the Department of Energy and Water Supply. The state is noted for its significant contribution to coal mining in Australia. The primary fuel for electricity generation in the state is coal with coal seam gas becoming a significant fuel source. Queensland has 98% of Australia's reserves of coal seam gas. An expansion of energy-intensive industries such as mining, economic growth and population growth have created increased demand for energy in Queensland.
SGSP (Australia) Assets Pty Ltd (SGSPAA), trading as Jemena, is an Australian company that owns, manages or operates energy infrastructure assets in the eastern states of Australia including Queensland and New South Wales, and gas pipelines and gas and electricity distribution networks in Victoria and the Northern Territory.

The South Australian blackout of 2016 was a widespread power outage in South Australia that occurred as a result of storm damage to electricity transmission infrastructure on 28 September 2016. The cascading failure of the electricity transmission network resulted in almost the entire state losing its electricity supply, affecting 850,000 SA customers. Kangaroo Island did not lose its supply, as the Kangaroo Island power station had been built to supply the island for the contingency of a failure in the power cable under the Backstairs Passage.
The Northern Gas Pipeline is a gas transmission pipeline in Australia. It runs 622 kilometres (386 mi) from Tennant Creek in the Northern Territory to Mount Isa in Queensland. It took 18 months to construct, and was completed in December 2018.
Leichhardt Power Station is a 60 MW open cycle gas turbine power station near Mount Isa in the Australian state of Queensland. The gas-fired power station was completed in 2014 and is capable of operating on diesel if gas is not available. It contains a single Rolls-Royce Trent 60 gas turbine. It is adjacent to the larger combined cycle Diamantina Power Station for which it provides backup. The power station was built under an engineering, procurement and construction contract by WSP Global. Mount Isa is not on the National Electricity Market, but does have piped natural gas from production in southern Queensland supplied via the Carpentaria Gas Pipeline. Both Diamantina and Leichhardt power stations are owned by APA Group. APA Group bought out its 50% equity partner AGL Energy on 31 March 2016 for A$151 million. It retained the long-term gas supply contract with AGL.
The Carpentaria Gas Pipeline is a natural gas pipeline connecting the gas fields to the city of Mount Isa in Queensland, Australia. It is 840 kilometres (520 mi) long between the Ballera gas plant in the Eromanga Basin in southwestern Queensland and Mount Isa, a significant mining community in northwestern Queensland. It was originally built to carry gas from the gas fields in the Eromanga Basin to the industrial areas around Mount Isa. Since 2018 it can also operate to carry gas from the Northern Territory via the Northern Gas Pipeline south to markets along the eastern seaboard of Australia. The supply points of the pipeline are Mica Creek Power Station, Diamantina Power Station, Mount Isa Mines, Century Mine, Phosphate Hill Power Station, and via the 96 kilometres (60 mi) Cannington Lateral, Cannington Mine and Osborne, Queensland. The Australian Pipeline Trust acquired full ownership of the pipeline in 2004. It had previously owned a 70% share with the rest owned by Santos, Delhi Petroleum and Origin Energy.
Tasmania, as an advanced economy with a globally high standard of living, uses a great deal of energy. Distinctive features of energy use in Tasmania include the high fraction of hydroelectricity usage, the absence of coal-fired electrical generation, relatively light usage of natural gas, particularly for domestic use, and a wide use of domestic wood-burning stoves. Energy production through hydroelectricity has been politically contentious, and conflicts over Tasmanian hydroelectric projects were integral to the formation of Green parties in Australia and across the world.
