Overview

Membership does not establish physical transmission capacity or price causation. Complete views require a matching receipt and mirrored row count; empty results are unknown coverage. Raw sources retain publication history internally.

Query contract

Published interface settlement-location and parent/child Pnode relationships with unnormalized source weighting factors. Membership does not establish physical transmission capacity or price causation. 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 interface settlement-location and parent/child Pnode relationships with unnormalized source weighting factors. Membership does not establish physical transmission capacity or price causation. 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.
