About the data
An InfraMap catalog of OpenStreetMap substations merged with the California Energy Commission substation list, ERCOT’s settlement point and bus mapping, the NYISO generator list, EIA-860 and US Census county boundaries. Each substation keeps the sources it came from.
A crosswalk links substations to pricing nodes, plants and queue points of interconnection.
The substation points on the map are public. The substation card, with the sources behind each field, and the pricing nodes at a substation are part of InfraMap Pro.
- Served
- Release of November 2026, about 80,000 substations, each with the sources it came from
- Updates
- Rebuilt about monthly from a fresh OpenStreetMap extract
- Licence
- Contains OpenStreetMap data © OpenStreetMap contributors, available under the Open Database License (ODbL)
Coverage by market
First year served: November 2026 catalog for every market.
The newest day in each market, checked every hour, is on Coverage.
Access
Free for everyone, with no account.
Where it appears: Substations layer, substation card.
MCP tools that return it: get_substation, find_substations_nearby, find_pricing_nodes. The MCP server is part of Pro; setup is on MCP server.

Periods and update notes for each source are on Data sources.
Known gaps
- Community-mapped points are incomplete and voltages are as tagged.
- Node and queue matches are made by name and distance and can be wrong.
Missing values stay missing: a null means the source has no usable record, never zero. Zero and negative values are shown as reported.
Questions it answers
- Which substations of 230 kV or more are within 20 km of a given solar project?
- Which plants, queue projects and pricing nodes connect at a given substation?
- Which substation does a given wind project connect to?
