description: 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.

  name: Western Power Outage Web API
  description: The undocumented first-party JSON API behind the public Western Power outage tracker. The outage page declares
    its own endpoints in markup — all-outages-endpoint="/api/corp/outage/all-outages" and single-outage-endpoint="/api/corp/outage/details/"
    — and all three operations answer anonymous unauthenticated HTTPS GET with application/json (verified HTTP 200 on 2026-07-27).
    listAllOutages returns every current and upcoming outage as a bare unpaginated array (211 records, 61 KB observed) with
    incident reference, planned/unplanned type, start and estimated restoration times, customers impacted, affected suburbs
    and a centroid. getOutageDetails adds an update history and bushfire, total-fire-ban, weather and fire-weather-warning
    hazard flags, answering an unknown identifier with HTTP 204 rather than 404. getSuburbOutageStatus returns a per-suburb
    rollup and never signals an error. Western Power publishes no reference, no terms of use, no versioning, no rate limits,
    no SLA and no support channel for any of it, and robots.txt disallows /api/ to crawlers. The OpenAPI below was derived
    by API Evangelist from live probes, not published by the provider.

  description: The anonymous read endpoints behind westernpower.com.au itself — site search, the news article feed and the
    careers vacancy feed. These are internal endpoints of the Optimizely/EPiServer corporate site, declared in the site's
    own JavaScript bundle and reachable without authentication (verified HTTP 200 on 2026-07-27). /api/search is backed by
    Optimizely Find and returns paged hits, a did-you-mean suggestion, content-type facets and — unusually — an embedded suburb
    outage rollup so a search box can surface outage status inline. /api/corp/vacancies and /api/corp/newsarticles serve the
    careers and newsroom listings. robots.txt disallows /api/, and Western Power publishes no documentation, terms of use
    or SLA for these endpoints. The OpenAPI below was derived by API Evangelist from live probes and from parameter names
    read out of the site's client bundle.

  name: Western Power Outage Areas Feature Service
  description: Live outage data for the South West Interconnected System, served as an Esri ArcGIS Online hosted feature service
    (layer 0, "Outage_Areas") that backs the public Western Power outage tracker at westernpower.com.au/outages/. Western
    Power does not document or advertise this as an API, but the service answers anonymous unauthenticated requests (verified
    HTTP 200 on 2026-07-27), is self-describing via the standard ArcGIS REST `?f=json` metadata convention, and supports the
    Query capability with a 2,000-record page size. Each outage polygon carries OUTAGETYPE, INCIDENTREF, ENARNUMBER, OUTAGESTARTTIME,
    ESTIMATEDRESTORATIONTIME, PLANNEDOUTAGE, NOCUSTOMERSIMPACTED, TIMEADDED, AFFECTED_AREA and AFFECTED_AREA_NOCUSTOMERS.
    No API key, token or registration is required; equally, no support, SLA, terms of use or deprecation policy is published
    for it.

  description: Western Power's network asset and capacity spatial data — distribution and transmission overhead powerlines,
    underground cables, poles, pillars, pits, transformers, enclosures, substations, streetlights, underground power project
    areas and the Network Capacity Mapping Tool forecast remaining-capacity layers — published as 36 datasets on the WA Government
    DataWA catalogue and served from the Landgate SLIP platform as ArcGIS REST MapServer/FeatureServer, OGC WFS and OGC WMS
    endpoints plus GeoJSON, GeoPackage, File Geodatabase and Shapefile downloads. DataWA labels these "open data subject to
    registering for access"; access is automatically granted on registering an email address and agreeing to Western Power's
    data licence terms and conditions. Anonymous calls are rejected — both the MapServer root and layer 10 returned HTTP 401
    Unauthorized on 2026-07-27, and the bulk download host redirects to /Account/Login. Authenticated access uses Esri token
    authentication via token.slip.wa.gov.au.
