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.
