Sources and methodology

Wind turbines

Our wind directory uses the US Wind Turbine Database. Each entry represents a turbine, identified by the source case ID. Names, coordinates, capacities, project commissioning years and confidence codes are retained with the original source record.

The source data are in the public domain. Read the official data and citation guidance.

Coverage and updates

The wind directory shows records from the latest completed import. The release label, source date and import time appear on the directory. Records missing from a later import remain in our database for reconciliation and are excluded from the current directory. Absence does not establish decommissioning. The individual original source records and input file checksum are retained for audit.

Capacity and project identities

Turbine capacity is converted from kilowatts to megawatts. Unknown values stay unknown. Totals cover only turbines with known capacity. Multiple turbines may share a project name; we do not treat matching names as verified project identities or add project capacity once per turbine.

Research limitations

These records describe infrastructure. They do not establish live operating status, development approval, landowner participation or available grid connections. Suitability screening and permitting histories require additional sources. No site suitability scores are currently published.

Further data planned

These additional datasets have not yet been imported into this module. An interconnection application is not evidence of planning approval.
