Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate to the ERCOT Public API (username/password plus subscription key)
Call the wind power production endpoint (report NP4-732-CD) with the subscription key header
Optionally filter by posted-datetime parameters to bound which forecast snapshots are returned
Parse fields for actual hourly averaged wind generation alongside short-term and rolling wind power forecast values
Note that each response covers a rolling 48-hour historical window plus a 168-hour forward forecast window
Schedule hourly polling to capture each new forecast vintage as it's posted, since old vintages are not retained indefinitely by this feed
Known gotchas
The feed blends actuals (rolling 48h back) and forecasts (rolling 168h forward) in one payload — code must distinguish them by timestamp relative to "now," not a dedicated flag field
Report NP4-742-CD is a geographical-region-level variant of this same data — confirm which report ID (system-wide vs by-region) matches the intended use case to avoid double counting
