Integral Energy is the second largest state-owned energy corporation in New South Wales, incorporated under the Energy Services Corporations Act 1995 from a merger between Prospect Electricity and Illawarra Electricity. Integral Energy is involved in electricity retail in addition to owning an electricity distribution network and currently holds licences to retail electricity in the contestable markets covered by the NEM (National Electricity Market).
Integral Energy distributes and retails electricity and services to 807,000 customers, or 2.1 million people. The company is increasingly operating outside of New South Wales, with the introduction of full retail contestability in other states. In addition to electricity retailing, Integral Energy also owns an electricity distribution network spanning 24,500 square kilometres in Greater Western Sydney, the Illawarra, and the Southern Highlands.
Their network value is estimated at A$2 billion and is made up of 25,000 transmission, zone and distribution substations, 370,000 power poles and 150,000 streetlights bound together by 33,000 kilometres of underground and overground cables. Integral Energy does not have a monopoly on the sale of energy within its distribution area and is in competition with private sector retailers such as AGL and Origin Energy since the introduction of full retail contestability in New South Wales.
Fifteen Integral Energy field service centres operate within their franchise, with staff to maintain the network, repair faults, respond to emergencies and service customers and developers in relation to customer connection and contestable projects. The centres are located in Bowenfels, Glendenning, Hoxton Park, Kandos, Katoomba, Moss Vale, Narellan, Nowra, Parramatta, Penrith, Picton, Shellharbour, Springhill, Ulladulla and South Windsor.
