Western Power is the Western Australian state-owned statutory corporation that owns and operates the electricity transmission and distribution network — the poles, wires, substations and streetlights — across the South West Interconnected System (SWIS), from Kalbarri in the north to Albany in the south and east to Kalgoorlie, across more than 103,000 km of powerlines, 825,788 poles and towers, 276,000 streetlights and 154 transmission substations. It is a regulated network distributor (DNO/DSO), not a retailer and not a generator; Synergy is the SWIS retailer for residential and small-business customers and AEMO operates the WA Wholesale Electricity Market. Its API posture is honestly minimal — there is no developer portal, no published API program, no developer documentation and no published OpenAPI anywhere on westernpower.com.au (developer./api./docs./data. subdomains all fail to resolve; /developers, /docs and /openapi.json all return 404). It is nonetheless not API-less. Three anonymous machine-readable surfaces were verified on 2026-07-27 — an undocumented first-party JSON API at westernpower.com.au/api/corp/outage/* that backs the public outage tracker and returns every current and upcoming outage, one outage with hazard flags and update history, and a per-suburb rollup; an Esri ArcGIS Online feature service serving the same outages as polygons with SQL, spatial and statistical query; and the corporate site's own search, news and vacancy endpoints. All are internal endpoints of Western Power's web applications — robots.txt disallows /api/ — with no reference, no terms of use, no versioning, no SLA and no support channel. Consumer energy data is real but not programmatic — a third party must register a business with Western Power and collect verifiable customer consent, after which up to two years of interval and accumulated metering data is delivered by email or a web portal, never an API. Australia's Consumer Data Right, the mandate that forced identical banking APIs and was then transplanted into energy, does not reach this organisation at all — CDR energy covers National Electricity Market retailers, and Western Australia sits outside the NEM while distributors were never designated data holders in any state. Its 36 network asset and capacity datasets are published through the WA Government DataWA/SLIP portals as "open data subject to registering for access" under Western Power's own data licence — WFS, WMS and ArcGIS REST endpoints that return HTTP 401 to an anonymous caller.
Western Power publishes 5 APIs on the APIs.io network, including Content API, Metadata API, Outages API, and 2 more. Tagged areas include Energy, Australia, Utilities, Electricity, and Grid.
Western Power’s developer surface includes authentication, support, engineering blog, documentation, developer portal, and 27 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
