Overview

MKTHOUR remains unqualified source text; event_time is file publication. Use one complete forecast vintage per footprint rather than stacking publications. Complete views require a matching receipt and mirrored row count; empty results are unknown coverage. Raw sources retain publication history internally.

Query contract

Published additional MW of available maintenance by East/West source file and calendar target label. MKTHOUR remains unqualified source text; event_time is file publication. Use one complete forecast vintage per footprint rather than stacking publications. Complete views require a matching receipt and mirrored row count; empty results are unknown coverage. Raw sources retain publication history internally.

Analysis rules

  • Keep SPP East and SWPW West separate. Never combine a published Total with its footprint components.
  • Do not sum model rows, publication attempts, repeated forecast vintages or duplicate weekly report entries as physical capacity.

Interpretation

  • Published additional MW of available maintenance by East/West source file and calendar target label. MKTHOUR remains unqualified source text; event_time is file publication. Use one complete forecast vintage per footprint rather than stacking publications. Complete views require a matching receipt and mirrored row count; empty results are unknown coverage. Raw sources retain publication history internally.
  • Model identities are not authoritative physical asset IDs, coordinates, outage attribution or nodal sensitivities.
