One of the biggest in the business

Integral Energy is one of Australia's largest energy suppliers. We operate a network that serves over 2.1 million people across 24,500 square kilometres, with an estimated value of $2.7 billion.

 

Our electricity supply is taken from the NSW transmission network at either 132,000 or 66,000 volts, and is reduced to 33,000, 22,000 or 11,000 volts through a network of 20 transmission substations and 147 zone substations.

 

Approximately 27,800 distribution substations further reduce the voltage to levels that meet our customers' home or business requirements, and the whole system is bound together by 33,000 kilometres of underground and overground cables.
