**Canonical:** https://apis.io/apis/atco/atco-electric-hosting-capacity-feature-service/  
**Provider:** ATCO — https://apis.io/providers/atco/  
**Base URL:** https://services7.arcgis.com/cw2emabghNLkoYlB/arcgis/rest/services/AGO_HostingCapacity/FeatureServer  
**Documentation:** https://electric.atco.com/en-ca/connections-services/new-connections-changes/micro-generation.html

ATCO Electric Hosting Capacity Feature Service is published by [ATCO](https://apis.io/providers/atco/) on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Grid, DER, Hosting Capacity, Distribution, and Geospatial. The published artifact set on APIs.io includes an API reference, an OpenAPI specification, and API documentation.

ATCO Electric's distributed energy resource (DER) hosting capacity data, published as a public Esri ArcGIS REST feature service and surfaced through the "DER HOSTING CAPACITY MAP" web application that ATCO Electric links from its micro-generation and connect-to-the-grid pages. The service is registered in ATCO's own ArcGIS Online organization (urlKey "ATCO", item id 7b4d2b3dcecb4a509f34cbfc3587ff3e, item title "ATCO Electric Hosting Capacity", description "CYME Hosting Capacity Map", access "public"). A single polyline feature layer, "Hosting Capacity (KW)", exposes FEEDER, PHASE, SUB_NAME, SUB_NUM, DATELOADED, DER_CAP_KW, DER_CAP_KW1 and PROJECT_AREA fields. An anonymous, unauthenticated query against layer 0 returned a feature count of 880,623 on 2026-07-27. Service capabilities are "Query" only, maxRecordCount 1000. There is no ATCO documentation page, no OpenAPI definition, and no published usage terms — the contract is the self-describing ArcGIS REST service descriptor itself, harvested verbatim into openapi/.
