Overview

NYISO scheduled transmission line outages by line PTID and equipment name, including scheduled out and scheduled in timestamps.

Query contract

Use FINAL or argMax over ingested_at for each event_time, ptid, and scheduled_out_time identity.

Analysis rules

  • Group only after preserving the declared grain: event_time, ptid, scheduled_out_time.

Interpretation

  • A scheduled outage is topology context, not proof that the facility was out or binding at a later price interval.

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.
