Installing solar in your town

Horizon Power is undertaking trials which will allow more of our customers to install rooftop solar.

With the increase in demand for rooftop solar, utilities around the world are facing similar challenges in how to connect increasing amounts of renewable energy to traditional electricity systems. In the case of smaller, isolated power systems or microgrids, like those operated by Horizon Power, the intermittency of renewable energy poses a challenge.

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, which we will progressively increase as we trial new technology that will allow for more renewable energy on our systems.

Watch our short video.

Can I install solar in my town?

The table below shows the kilowatts available in each town that can be utilised by rooftop solar. Some of our towns have already reached their Distributed Energy Target and so we are unable to accept solar applications at this time.  

Check your eligibility to install rooftop solar.
