Business energy prices

Each year, the WA State Government reviews our fees and charges and sets the price that our customers pay for electricity, known as ‘tariffs’.

Your business tariff is based on the type of business you are operating and how much energy you are likely to consume per year. Learn more about electricity prices. 

If you have a question about your tariff or pricing plan, please contact your local Horizon Power office.

Moving to a building under construction?

If you’re moving into a building with no existing power connection, you'll need to install a meter. This could be a temporary power supply for your builder to carry out works, or a permanent supply because you’re ready to move in.
