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.
