Western Australian Power & Wastewater Rules, by Council
Every council covered on our WA livestock page sits within Western Power's South West Interconnected System (SWIS), which runs from Kalbarri in the north to Albany in the south and Kalgoorlie inland — so there's no distributor-level variation to report between them (see the state-wide WA article for the export pathway choice and wastewater thresholds).
Before you act on any of this: this page is a research aid, not a legal reference. Always confirm your exact connection requirements directly with Western Power before assuming any figure applies.
All councils on this page are Western Power/SWIS territory: Stirling, Wanneroo, South Perth, Nedlands, Rockingham, Swan, Joondalup, Cockburn, Kalamunda, Armadale, Melville, Kwinana, Mandurah, Bayswater, East Fremantle, Bassendean, Vincent, Albany and Busselton all sit within the SWIS, one of the largest isolated grids in the world by area, with no physical connection to the National Electricity Market or any other system. None of these councils have any Horizon Power presence — that network covers the Pilbara, Kimberley, Gascoyne, Mid West and Goldfields regions, well outside this list.
The May 2026 export pathway choice applies the same way everywhere on the SWIS: whether you choose full export access (with remote disconnection capability) or the fixed 1.5kW static cap is a per-connection decision under Western Power's new rules, not something that varies by council. Wastewater approval (the Department of Health's 540L/day and 8-person ancillary-dwelling thresholds) is also consistent statewide, administered through your local government regardless of council.
Frequently Asked Questions
Does the distributor vary between WA councils covered on this site?
No. Every council covered - the full Perth metro area, plus Mandurah, Albany and Busselton - sits within Western Power's SWIS. None have any Horizon Power presence, which is confined to the Pilbara, Kimberley, Gascoyne, Mid West and Goldfields.
Does the May 2026 export pathway choice differ by council?
No. Choosing between full export access or the fixed 1.5kW static cap is a per-connection decision under Western Power's rules, applying identically regardless of which SWIS council you're in.
Where do I check my exact connection requirements in WA?
Western Power's own website is the definitive source for your specific address, since the SWIS covers such a large and varied geographic area.
