Our network

We operate and maintain one of Australia’s largest electricity networks covering an area of around 25,000 square kilometres in South East Queensland stretching from the NSW border in the south to Gympie in the north. This includes the major population areas of Brisbane, the Gold and Sunshine Coasts, Ipswich, Redlands, Logan and Moreton Bay.

We provide services more to than 1.5 million domestic and business customers, across a growing population base of around 3.5 million people.

Our power is supplied through more than 55,000km of underground cables and overhead lines, 288 substations and 51,000 distribution transformers. Our high-performing network consists of property, plant and equipment worth more than $12 billion.
