Renewable energy buyback schemes

Changes from 1 July 2019
We are pleased to announce that from 1 July, rooftop solar will become more accessible across many WA regional towns.


Use the calculator below to determine if you are eligible to install solar and apply for our buyback offer.

Eligibility calculator


If you wish to apply for 1MW, please enter as 1,000kW


If you don't use all of the electricity you generate, we may be able to buyback the excess you export into the electricity system. We offer buyback rates for each town which reflect our cost of electricity generation and distribution in that town. Because these costs vary greatly between towns across our vast service area, the rates differ significantly also. Use the calculator above to find out the buyback rate in your town. 

Buyback rates are reviewed annually and the amount payable is subject to change. We will advise you of any changes that affect your buyback rates.

It is important that you receive approval from Horizon Power to install a renewable energy system even if you do not wish to participate or are not eligible to participate in our buyback offer. 

Residential customers

We offer the buyback price to eligible residential customers who wish to install a five kilowatt or less renewable energy system. For systems that are over five kilowatt in size, we offer a buyback price in towns where the cost of generating electricity is high. The Western Australian Government established the requirement for retailers to offer a buyback scheme through the  Electricity Industry (Licensing Conditions) 2005

Business customers

We offer a buyback price to business customers in towns where the cost of generating electricity is high. Not all business customers will be eligible for the buy back. It will be offered at Horizon Power’s discretion and will require further commercial negotiations. 

Please note: You must use the eligibility calculator to determine if you are able to install a system and are eligible to apply for the buyback price. As we process applications daily, the information provided through our calculator and our website is subject to change and provided as a guide only.

For each town, we have a certain amount of capacity for rooftop solar that can be safely installed on the power system without compromising the reliability of power supplies to all of our customers. This is our Distributed Energy Target. In some towns, a solar system can only be installed with a generation management system. Other towns have already reached their Distributed Energy Target and so we are unable to accept solar applications at this time.
