What we do

Western Power is a Western Australian State Government owned corporation responsible for building, maintaining and operating an electricity network that connects our 2.3 million customers to traditional and renewable energy sources, delivering an essential service to our community.

We’re at the forefront of the energy industry in leveraging new technologies, including integrating microgrid and battery storage solutions. We’re planning the grid of the future that’s leading the way to a cleaner, brighter and more resilient energy supply for the next generation.

For more than 70 years, we’ve been providing West Australians with safe, reliable and efficient energy. Our vast transmission and distribution network, and the people behind it, seamlessly connect our homes, businesses and essential community infrastructure to an increasingly renewable energy mix, supercharging our vibrant West Australian lifestyle.

Our network coverage

We build, maintain and operate the electricity network in the south west corner of Western Australia. The Western Power Network forms the vast majority of the South West Interconnected Network (SWIN), which together with all of the electricity generators, comprises the South West Interconnected System (SWIS).

Our strategy

Our new 10-year corporate strategy centres on ‘powering the lives of our community’. It recognises that our community of 2.3million Western Australians want Western Power to safely provide reliable, increasingly renewable electricity while keeping costs low and supporting jobs and growth.  

Our strategy sets out our plan to meet these needs by transitioning to a modular grid and supporting the decarbonisation of our local economy.   

WA is preparing for a climate-resilient and prosperous decarbonised future based on a shift to net-zero emissions. The grid has a critical enabling role in reducing emissions in our economy and we’re actively investing to ensure the grid has the technologies needed to increase the share of renewable generation powering our community over the next decade. It will enable other industries to achieve their emission reduction goals through further electrification.   

The rapid uptake of rooftop solar by the community, which is set to rise to one in every two households by 2030 highlights our transition to a renewable energy future. Currently around 30 per cent of electricity is generated by renewables and this will continue to increase in the future.  

The changing generation mix provides exciting opportunities in how we manage the network, plan for its effective operation in the future, and deploy innovative customer solutions.   

By transforming our network into a modular grid we’ll enable the continued uptake of renewables, manage climate risk and end of life assets while providing safe, reliable and affordable electricity services to our community, regardless of where they live.   

Our new strategy involves transformational investment in existing assets and new technology and builds on the work we’ve done to successfully trial and test innovative solutions like stand-alone power systems (SPS), battery storage at Perenjori, and the Kalbarri microgrid.   

The modular grid is comprised of three zones:   

  • a tightly meshed urban network with increasingly more underground assets that will service most of our customers for decades to come   
  • a hybrid network of mostly overhead assets and new technologies like SPS where possible    
  • an autonomous stand-alone network of disconnected power systems (e.g. SPS and microgrids).   

For metropolitan customers, we’ll continue to focus where possible on undergrounding assets and enabling the growth of rooftop solar. For regional customers, it will mean new ways of delivering power, like SPS and microgrids. For customers in between those two areas, we’ll have a hybrid network; that is, a mix of a largely overhead power network, with new technology options like SPS where they make sense for the community.     

This is being supported by improving the integration of distributed energy resources and coordination with advanced meter infrastructure (AMI), modernised connection standards for DER, and greater amounts of grid-connected storage to help manage load and generation mismatches.  

We put the community at the centre of everything we do. As a GTE we’re owned by the people of Western Australia which means we have a rigorous approach to financial sustainability while delivering the energy needs of the community. 

Our 10-year strategy lays out our plan to future-proof the network for the benefit of all Western Australians.
