Horizon Power


We supply electricity to more than 100,000 residents and more than 10,000 businesses in regional towns and remote communities across Western Australia. Our service area is vast, approximately 2.3 million square kilometres, which means Horizon Power services the biggest area with the least amount of customers in the world. For every 53.5 square kilometres of terrain, we have one customer. We operate in the Pilbara, Kimberley, Gascoyne, Mid West and the southern region of Western Australia which includes the Southern Goldfields, Esperance, Hopetoun and Norseman. We have regional depots based in Karratha, Broome, Kununurra, Carnarvon, Esperance and Port Hedland, with administrative support being delivered from Perth. We maintain three systems connected in the East Kimberley (Kununurra, Wyndham and Lake Argyle), two rural systems (Esperance and Hopetoun), the North-West Interconnected System between Port Hedland and Karratha and 32 microgrids, or isolated power systems. The systems are exposed to intense heat and cyclonic conditions in the north, and ravaging storms in the south. Our decentralised delivery model ensures we have a presence on the ground so that we can respond immediately to local issues and tailor our services to customers’ individual requirements. We employ people who live and work in the community and who intimately know your energy needs. The way we generate electricity varies between our major interconnected systems and our microgrids, with most mainstream towns serviced by gas and smaller communities by diesel. Increasingly, renewable forms of energy are also being harnessed.
