Overview

publish_time is the report vintage; curtailment start and end are the operating interval. This is a generator outage/availability report; for published wind and solar curtailed energy use caiso.curtailment.

Query contract

Preserve one canonical row per (publish_time, outage_mrid) before aggregating.

Analysis rules

Group only after preserving the declared grain: publish_time, outage_mrid.

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.

Dataset	Description
OASIS `AGGR_OUTAGE_SCH_GRP`CAISO · day publication	CAISO's OASIS `AGGR_OUTAGE_SCH_GRP`. 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.
Western Generation Outage Forecasts by Hub and FuelCAISO · hourly delivery; six-hour collection	Hourly generation-outage forecasts across Western trading hubs and fuel categories, with approximately one month of future delivery intervals per report-day vintage.
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.
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.
