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.
