EnergyAustralia

In 2005, TXU Corp sold all its Australian assets to Singapore Power, which retained the distribution businesses (electricity and natural gas distribution networks) in Victoria, and onsold the retail and generation businesses to the Hong Kong–based CLP Group, which also owned the Yallourn Power Station, in Victoria's Latrobe Valley. In Australia, CLP traded as TRUenergy, and became the fifth largest energy retailer in Australia. In 2011, TRUenergy acquired from the New South Wales Government the state's electricity retail business and trade name of EnergyAustralia. Following the sale of the government's electricity retail assets, the government changed the name of the remainder of the government enterprise to Ausgrid, and in 2012 TRUenergy changed its name to EnergyAustralia.

In 2013, EnergyAustralia acquired Wallerawang Power Station, now closed, along with Mount Piper Power Station, both in New South Wales, from Delta Electricity for A$160 million.

In 2015, EnergyAustralia closed its call centre in Melbourne, outsourcing up to 300 jobs to the Philippines.

In 2018, EnergyAustralia became one of the 17 energy businesses who supported the launch of the Energy Charter, a global initiative aimed at bringing together all parts of the power supply chain to give customers more affordable and reliable energy.

In 2021, EnergyAustralia announced that it will close the Yallourn Power Station in mid-2028, four years ahead of schedule, and instead build a 350-megawatt power-generating battery in the Latrobe Valley by the end of 2026. At the time, Yallourn produced about 20% of Victoria's electricity.

EnergyAustralia supplies electricity and natural gas to more than 1.7 million residential and business customers throughout Australia.

In 2021 to 2022, it emitted 16.2 million tonnes of carbon dioxide, making it Australia's second largest emitter.
