  title: SCE DRPEP ArcGIS REST Services Feature Services API
  version: '11.1'
  summary: Anonymous, key-free Esri ArcGIS REST interface behind Southern California Edison's Distribution Resources Plan External Portal (DRPEP).
  description: 'Machine-readable description of the anonymous grid-data API that Southern California Edison serves at `drpep.sce.com`. SCE publishes **no** OpenAPI, no developer portal, and no written API reference for this surface; this document was generated by API Evangelist from live, unauthenticated probes of the service itself (ArcGIS Enterprise 11.1 REST, `f=json`) on 2026-07-27 and from the service, layer, and field descriptors saved verbatim under `arcgis/` in this repository. Every path, parameter, and example below was observed answering anonymously with HTTP 200 - nothing here is aspirational.


    The catalog exposes 15 hosted FeatureServers covering 47 feature layers and 11 tables: Integration Capacity Analysis (ICA) circuit segments and their generation/load constraint layers, distribution circuits, substations, the Distribution Deferral Opportunity Report (DDOR), the Grid Needs Assessment (GNA), Locational Net Benefit Analysis (LNBA), Public Safety Power Shutoff (PSPS) boundaries, CPUC fire-threat tiers, transmission projects, available-load and subtransmission heat maps, and load-growth penetration. The ICA circuit-segment layer alone answers 676,467 features.


    Read-only: every hosted service advertises `capabilities: Query` (DRP_Transmission_Projects also allows `Extract`). There is no write surface, no API key, and no rate-limit header. The sibling `Utilities` folder on the same server is NOT open - it returns `{"error":{"code":499,"message":"Token Required"}}`.


    This spec does not cover SCE Green Button Connect My Data. That interface is real and mandated by CPUC tariff Rule 26, but SCE discloses no base URI, endpoint, or scope publicly; see `authentication/` and the repository review for what is actually known.'
