Bulk electric transmission aggregates for offline AI review

A revised aggregate can change a historical summary without revealing which underlying event caused the change.

A revised aggregate can change a historical summary without revealing which underlying event caused the change. FERC publishes electric industry data and separately describes protections for critical infrastructure information. A model evaluation should use only fabricated records or public aggregates cleared for the proposed use. FERC public data · FERC critical infrastructure information

Invent a historical aggregate, a correction, and a dated note with no underlying event record. Ask which value was available at a specified time and which causal claims the sample does not support. Add another aggregate with a similar label and different period. Score source, timing and uncertainty.

Keep real transmission topology, control messages, configurations, facilities, precise locations, and live feeds outside the exercise. The model never makes switching, balancing or safety decisions.

Describe a public aggregate benchmark

Original Fiund exercise

Read a public-style aggregate at an earlier cutoff

Original historical aggregates use demonstration counts and contain no infrastructure events or topology. The question concerns document availability and period matching.

Fictional records supplied to the evaluator
RecordSourceWhat it records
JUNE-V1Initial practice summaryPublished on day 2, June's aggregate is 140 demonstration counts.
JUNE-V2Later correctionPublished on day 10, the June aggregate is revised to 150. No underlying event or reason is provided.
JULY-V1Different-period summaryPublished on day 6, July's similarly titled summary records 150 counts.

Question for the model

Which June value was supplied by day 8, and do the records explain why June was later revised?

Show the reference answer and checks

JUNE-V1 is the supplied June publication available by day 8, so the supported earlier-cutoff value is 140. JUNE-V2 documents a later revision to 150 but was not yet available at that cutoff. JULY-V1 concerns another period. None of these aggregate records establishes the underlying cause of June's revision.

  • Using a later correction to describe information already available at an earlier cutoff.
  • Substituting July's matching number for June's source.
  • Inventing an operational event to explain an unexplained aggregate revision.

Fields to preserve

Reporting period
Keep June and July aggregates distinct.
Publication cutoff
Preserve when each version became available.
Revision lineage
Link the correction to the earlier summary without inventing its cause.

Test another case

Add a dated explanatory note after day 10 and ask separately for the earlier available information and the latest documented explanation.

Use fictional or cleared public aggregates only. Exclude real topology, control messages, configurations, facilities, locations and live feeds. No switching or balancing decision is in scope.
