Open in Data Ask the agent

One row per: report x section x outage; Every 3 hours cadence
Evidence: Observed market data; Published observations from the named source
Time basis: Point-in-time records; UTC · event_time

Overview

Query contract: Preserve one canonical row per (report, section, outage_id, out_time, name) before aggregating.
Analysis rules: An outage appears in several reports; count distinct outage_id within one report or deduplicate across reports.
Interpretation: A report lists outages still open when compiled, so it holds outages that began years earlier.

Access

Dataset	Description
BPA Planned Transmission OutagesBPA · every 6 hours	BPA's posted transmission outage plans (rolling year, monthly initial and final), every revision kept, one row per outage request.
AlertsISONE · ISO-NE source publication	ISO-NE's published Alerts source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.
California Independent Storage OutagesCalifornia independent storage · Per notice	Capacity reductions the independent storage fields post, per gas day: remaining injection and withdrawal capacity in Dth/d, with the notice subject and description. Published by each facility operator.
Completed-year archive of daily outage reportsSPP · year publication	SPP's Completed-year archive of daily outage reports. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.
