ATCO’s prices for the gas supply network in Western Australia are overseen by an economic regulator – the Economic Regulation Authority (ERA). Every five years, we submit our plans and proposed prices to the ERA for consideration and approval.

This plan, known as an Access Arrangement, outlines our programs that are designed to enable us to deliver a safe, reliable, affordable and sustainable energy source for Western Australians – now and into the future.

We are now seeking community feedback on our sixth Access Arrangement (AA6) Draft Plan for 2025-2029.


Our network infrastructure is uniquely positioned to support Western Australia’s energy transition.

Our investment in the 14,500km of pipeline buried under Perth’s greater metropolitan area will be integral to supporting Western Australia’s energy transition.

Our plan for 2025 to 2029 maintains our existing focus on efficiency, safety and reliability, but also considers how we can transform our network to achieve net zero emissions by 2050.


Our Draft Plan is underpinned by the insights of more than 1000 customers and stakeholders, gathered over 400+ hours of consultation, to better understand what the community expects and desires from the gas network.

Nearly 9 in 10 customers consider our suite of investment programs to be of personal importance, with 97% of residents surveyed believing that having access to gas is important.

Our plans reflect this support and increasing demand for access to a safe and reliable network, with an additional 78,000 new customer connections predicted over the five-year period.


In the current high inflation and interest rate environment, we understand affordability is more important than ever for our customers.

We have designed our Draft Plan to balance the priorities of delivering a safe and reliable gas network; transitioning to a low carbon economy; and keeping the service we deliver efficient to keep costs as low as possible for households and businesses.

For a typical residential customer, the cost to provide a safe, efficient and reliable gas distribution network, and to prepare it for Western Australia’s energy transition, will increase by less than a dollar a week.
