Overview

These operational zone identifiers are source-native and should not be assumed to match planning-zone or local-resource-zone geography without an explicit crosswalk.

Query contract

Preserve one canonical row per (event_time, zone) before aggregating.

Analysis rules

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

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.
