Live Grid Metrics

MISO public operating telemetry for area control error, net actual and scheduled interchange, and north-south regional transfer.

Native record

operating metric x source interval

Evidence

Observed market data

Published observations from the named source

Time basis

Point-in-time records

UTC · event_time

Overview

Preserve metric and the source's flow/limit direction; a signed value without that context is ambiguous.

Query contract

Select the latest ingested_at row for each metric and raw_interval_est before use.

Analysis rules

Keep metric names and published direction fields explicit; signed interchange or transfer values are ambiguous without them.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.

Dataset	Description
Day-Ahead Net Scheduled InterchangeMISO · hourly (Day-Ahead)	Hourly day-ahead net scheduled interchange in MW by MISO sub-region. This is a cleared schedule, not observed physical interchange.
Historical Net Scheduled InterchangeMISO · hourly	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.
Net Actual InterchangeMISO · hourly	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.
Real-Time Net Scheduled Interchange DeltaMISO · hourly	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.
