Access arrangement
Access arrangement
An access arrangement sets out the terms and conditions, including prices, for our direct customers such as generators, major users and retailers. Retailers (like Synergy) pass network charges through to households and businesses.
We submit a five-year proposal to the Economic Regulation Authority (ERA) under the Electricity Networks Access Code 2004. The ERA consults publicly, reviews our proposal and decides the revenue we can recover and the service standards we must meet.
AA6 is our sixth five-year plan, covering 1 July 2027 to 30 June 2032. We’re developing the proposal now, with community, customer and stakeholder input informing the services and investments we put forward.
Across 2025–2026 we’re inviting feedback on priorities, trade-offs and our draft plan, including through Community Working Groups and targeted sessions with residential, business, industry and local government customers. What we hear will shape the Initial Proposal and areas where we do deeper engagement.
It’s designed to serve the long-term interests of Western Australians by ensuring our essential services are delivered safely, reliably and efficiently, at a fair cost, with transparent decisions and opportunities to have a say through the determination process.
To avoid overlapping with the 2025 State Election caretaker period and to align with potential Access Code changes, a one-year deferral was approved in January 2025. The AA6 Initial Proposal is due 1 February 2027; the period still begins 1 July 2027, with 2027–28 tariffs carried over from 2026–27 and incentive mechanisms paused while the ERA completes its determination.
