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 Data Miner 2.

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.

Dataset	Description
Area Control ErrorPJM · sub-minute (~15-second source; polled every 5 minutes)	PJM area control error in MW at its native fast operating cadence. ACE is the signed instantaneous difference between scheduled and actual balancing obligation; it changes within seconds and should not be treated as a slowly varying reserve or energy quantity. Source: PJM Data Miner 2.
Actual InterchangeISONE · hourly	ISO-NE actual interchange by published external location, with signed interchange, purchase, and sale components. Preserve location and direction; do not sum a net value with its purchase and sale components.
Ba Interchange HourlyISONE · ISO-NE source publication	ISO-NE's published Ba Interchange Hourly source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.
Day-Ahead Lake Erie CirculationNYISO · hourly (DAM)	NYISO day-ahead hourly scheduled Lake Erie loop-flow circulation. It provides the forward scheduled counterpart to real-time Lake Erie circulation.
