Western Power Public Secure Services (SLIP)

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.
