Con Edison Hosting Capacity Map REST API
Con Edison's distribution-grid open data, published as anonymously readable Esri ArcGIS REST feature services behind the public Hosting Capacity Map. Con Edison's own documentation states that "REST API access allows users to overlay the Con Edison Hosting Capacity Map data with their own GIS systems and mapping tools" and that the endpoints are exposed on the map's "Rest API" tab. The services cover CECONY and Orange & Rockland segmented and network hosting capacity for distributed generation, EV load-serving transformer capacity, 33kV feeders, non-wires-solutions impacted networks, Locational System Relief Value eligibility, disadvantaged and overburdened communities, and the IEDR-facing hosting capacity layers. No login, API key, or agreement is required; every service probed returned HTTP 200 unauthenticated. Con Edison states the data "is being provided for informational purposes only and is not intended to be a substitute for the established interconnection application process."
