Integral Energy ranked as the second largest state-owned electricity provider in New South Wales. It was created under the Energy Services Corporations Act 1995 through the consolidation of Prospect Electricity and Illawarra Electricity. The firm engaged in electricity retailing and managed a distribution network, having previously held licences to sell electricity within the competitive sectors of the National Electricity Market (NEM).
At its height, Integral Energy catered to 807,000 customers, serving an estimated population of 2.1 million. Its distribution infrastructure covered an area of 24,500 square kilometres, encompassing regions such as Greater Western Sydney, the Illawarra, and the Southern Highlands. By 2011, the network's worth was appraised at A$2 billion, including 25,000 substations, 370,000 power poles, 150,000 streetlights, and 33,000 kilometres of both underground and overhead cabling. After New South Wales introduced full retail competition, Integral Energy competed against private electricity retailers including AGL and Origin Energy.
From April 2008, Vince Graham served as CEO of Integral Energy, taking over from Richard Powis. The company maintained fifteen field service centres responsible for network upkeep, fault resolution, emergency management, and customer connections. These facilities were distributed across its service territory in locations such as Bowenfels, Glendenning, Hoxton Park, Kandos, Katoomba, Moss Vale, Narellan, Nowra, Parramatta, Penrith, Picton, Shellharbour, Springhill, Ulladulla, and South Windsor.
In 2011, the retail business and brand of Integral Energy were divested to Origin Energy by the NSW Government. The network operations that remained were rebranded as Endeavour Energy following governmental restructuring. Subsequently, in June 2017, a consortium led by Macquarie Infrastructure & Real Assets acquired a controlling 50.4% interest in Endeavour Energy’s network assets through a 99-year lease agreement. Additional investors included AMP Capital, British Columbia Investment Management Corporation, and the Qatar Investment Authority.
