Live NYISO dashboard: ICAP peak risk and load forecast
Today's Load vs. Current Peakcross the white line and today is the new season peak
No call today. Weekends and NERC holidays have never set the New York season peak, so this program excludes them and ineligible days carry no probability. The next business-day call publishes by 10 AM ET.

Zone shapes trace NYISO's published load-zone map, A west to K east (build recipe and ground-truth checks in data/geo). Zone fill and price tags are real-time 5-minute LBMPs. City readings are live NWS station observations, colored by anomaly vs each hour's ERA5 seasonal normal (2019-2024).
The hour to beat
provisional, from observed hourly load- cp1Thu, Jul 231.1 GW6:00 PM ET
One peak decides the season: the single highest NYCA hour, business days June through September. NYISO's official determination settles after the capability year closes, from verified metered load — a late reporting revision can move a razor-thin ranking.
