Energy supply across regional WA

Where does your energy come from? 

Here in regional WA, we do things a bit differently to the rest of Australia. When it comes to energy, we’re not part of the national electricity market or the eastern gas region.

 

Where does the energy that powers your home come from?

Learn more about how Horizon Power delivers safe, reliable power to the largest service area in all of Australia - and how they're planning for a low carbon renewable energy future.

New solutions for a renewable energy future

There are many types of renewable energy sources in Western Australia – including plenty of sunshine and wind power. We’re working to overcome the technical barriers of increased renewable energy on our network so more of our customers can install rooftop solar, reduce their energy costs and have a more balanced supply of energy.

Planning for the future

We’re working on some industry-leading trials to provide our customers with the kind of solutions they need for their energy future.  

Increasing renewables on the grid

Our electricity generation mix is changing to include more renewables. At the moment, that mix includes diesel, gas, solar, wind and hydro. We’re tackling the opportunities and challenges associated with the move away from fossil fuels, making sure this transition to renewables doesn’t impact the stability of the network.  

Reducing our reliance on diesel

We’re reducing our reliance on diesel generation by integrating more sustainable and environmentally friendly energy sources such as solar, wind, batteries, and hydrogen.  

Greater access to rooftop solar

We’re working with our customers and communities to allow for even more rooftop solar to power our remote communities. One example of this is our Distributed Energy Resource Management System (DERMS) which allows energy flows to be balanced to help keep the power supply stable.

Getting future ready

Along the way, we’re working with local communities to design the kind of energy solutions our customers need - to reduce the cost of your electricity and invest in a greener future for everyone.
