P-14B Transmission Outage Schedule

NYISO's public P-14B transmission outage schedule, kept as one row per outage per published version of the list, with equipment PTID, name and type, scheduled out and in times, and status with its status time.

Outages & Grid Events data

Open in Data

One row per: source_time x outage_id; Irregular revisions, polled hourly cadence
Evidence: Observed market data; Published observations from the named source
Time basis: Point-in-time records; UTC · event_time

Overview

event_time is the scheduled out time; source_time is the version's publication time, so every revision NYISO posts is retained. The current schedule is the rows at the latest source_time; counting one outage_id across versions double-counts it. Status values include UPDATED, EXTENDED, EXT FORCED, FORCED, DENIED, and CANCELLED, so a DENIED or CANCELLED row is not an outage that took place. Distinct from nyiso.outage_schedule, the date-stamped operational feed of generator and transmission outages.

Query contract: Preserve one canonical row per (source_time, outage_id) before aggregating.
Analysis rules: Group only after preserving the declared grain: source_time, outage_id.
