Interchange datasets
Dataset	Cadence	Rows
ISO-NEActual InterchangeATG Data·ISONE·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.	hourly	43.0K2022
ISO-NEBa Interchange HourlyATG Data·ISONE·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.	ISO-NE source publication	38.5K2022
NYISODay-Ahead Lake Erie CirculationATG Data·NYISO·NYISO day-ahead hourly scheduled Lake Erie loop-flow circulation. It provides the forward scheduled counterpart to real-time Lake Erie circulation.	hourly (DAM)	152.5K2009
NYISODay-Ahead Market Energy ReportATG Data·NYISO·NYISO day-ahead energy-market summary by hour, including load forecast, total scheduled load, generation scheduled, imports, exports, net imports, and virtual load/supply.	hourly (DAM)	221.1K2000
MISODay-Ahead Net Scheduled InterchangeATG Data·MISO·Hourly day-ahead net scheduled interchange in MW by MISO sub-region. This is a cleared schedule, not observed physical interchange.	hourly (Day-Ahead)	123.4K2026
ISO-NEExternal Flow 5mATG Data·ISONE·ISO-NE's published External Flow 5m 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.	ISO-NE source publication	1.9M2023
MISOHistorical Net Scheduled InterchangeATG Data·MISO·Reconciled historical hourly net scheduled interchange in MW by adjacent balancing authority. It supports counterparty schedule history and should not be relabeled as measured physical flow.	hourly	55.5K2026
NYISOHour-Ahead Market Energy ReportATG Data·NYISO·NYISO hour-ahead market energy summary by hour, including internal bilaterals, generation capacity bid, generation scheduled, imports, exports, and net imports.	hourly (HAM)	229.4K2000
ISO-NEInterchange 15mATG Data·ISONE·ISO-NE's published Interchange 15m 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.	ISO-NE source publication	110.9K2023
NYISOInterface Flows & LimitsATG Data·NYISO·NYISO five-minute external interface flows and positive/negative transfer limits by interface point. This is the live interchange and transfer-limit context behind import/export stress and congestion.	5-minute	48.6M2001
MISOLive Grid MetricsATG Data·MISO·MISO public operating telemetry for area control error, net actual and scheduled interchange, and north-south regional transfer. Preserve metric and the source's flow/limit direction; a signed value without that context is ambiguous.	1-minute snapshots	69.7K2026
ISO-NELoad Gen Interchange HourlyATG Data·ISONE·ISO-NE's published Load Gen 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.	ISO-NE source publication	40.8K2022
MISONet Actual InterchangeATG Data·MISO·Observed hourly net actual interchange in MW between MISO and each adjacent balancing authority. Preserve MISO's sign convention and named counterparty when describing imports or exports.	hourly	510.7K2026
NYISOReal-Time Lake Erie CirculationATG Data·NYISO·NYISO real-time five-minute Lake Erie loop-flow circulation. Positive values indicate clockwise / into-NYISO circulation, an important transfer-path context for New York imports and congestion.	5-minute	1.8M2009
MISOReal-Time Net Scheduled Interchange DeltaATG Data·MISO·MISO system-wide forward and real-time net scheduled interchange in MW and the published delta between them. These are schedules, not metered tie-line flows.	hourly	56.6K2026
