Overview

NYISO station-level weather forecast feed used by the load model, including maximum/minimum temperature and wet-bulb forecasts by station and vintage date.

Query contract

Use FINAL or argMax over ingested_at per station_id and vintage_date, and parse fixed-width MM/DD/YYYY vintage_date before chronological ordering.

Analysis rules

  • Group only after preserving the declared grain: event_time, station_id, vintage_date.

Interpretation

  • This is station weather input used by NYISO's load forecasting process, not a load forecast or a load-zone population-weighted temperature.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.
