Overview

The table covers the eleven NYISO zones and is the settlements-grade actual-load series used by the NYISO map cards; system actual load is computed by summing the zone rows.

Query contract

Use FINAL or argMax over revision time. A system total is the sum of one canonical row for each of the 11 load zones; never sum duplicate revisions or also include a system-total row.

Analysis rules

  • Canonicalize to one row per load zone and operating hour before summing.
  • For day-over-day comparisons, compare like operating hours and the same zone set.
