Overview

publish_time is the report vintage; curtailment start and end are the operating interval.

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.
