Overview

PJM RTO is the whole-footprint aggregate and PJM MISO is another aggregate; neither should be added to the component tie rows. Flow signs are preserved as PJM publishes them, and this feed does not contain transfer limits. Source: PJM Market Data.

Query contract

Read one canonical revision per tie_flow_name and event_time, preserving PJM's published sign.

Analysis rules

  • PJM RTO is the whole-footprint net-interchange aggregate; do not add it to component ties.
  • PJM MISO is also an aggregate; exclude aggregate rows when listing or summing component ties.
