Horizon Power: Supplying power to more than 47,000 customers

State-owned Horizon Power is one of the largest energy suppliers in Western Australia.

Customers in Western Australia don’t have much choice when it comes to their energy suppliers. If you live in the north or east of the state then you’ll probably already know about Horizon Energy, but if you’re thinking of moving there we’ve got a full guide to get you up to speed.

Who is Horizon Power?

Owned by the Western Australian state government, Horizon Power provides power to over 100,000 homes and 10,000 businesses across the state. It specialises in the area known as the North West Interconnected System (NWIS) and the surrounding rural regions. It provides energy from a range of sources, and has a firm commitment to developing infrastructure and systems for the generation of renewable energy across the state.

What services do they offer?

Horizon Power provide the following services for Western Australian residents and businesses:

  • New electricity and metre connections
  • Electricity network upgrades
  • Emergency servicing, such as power faults and outages
  • Non-urgent faults, such as repairing streetlights
  • High-quality solar energy service

Could I switch to Horizon Power?

The energy market in Western Australia is still regulated by the state government, which means that consumers do not yet have a choice over who they get their energy from.

What are the pros and cons of using Horizon Power?


  • Simple plan. You pay a small daily fee for your connection and then you buy your energy on top of that. It is simple, easy to track and easy to save money through energy efficiency.
  • No choice. This isn’t Horizon Power’s fault, but the regulation of the energy market means that your energy provider will be determined by where you live, not by what you choose.
  • Complete solar service. Horizon Power offer a comprehensive solar service from consultation through to installation. Head to their solar section on their website to get a free quote.
  • Premium products. Their products are designed to suit the climate conditions of Western Australia, with extended warranty.


  • Limited solar availability. Horizon Power's solar option is only available to customers in Karratha.
  • Limited solar products. Although they offer a Tier 1 solar service, there is only a small number of solar products available to customers, compared to other providers.

How do I switch to Horizon Power?

It’s not possible to switch power to Horizon Power, but if you live in an eligible area in Western Australia in a non-connected house and are interested in getting connected then contact Horizon Power by visiting its website.
