ERCOT daily summaries of hourly nodal-price distributions, July 14 to 25, 2026

ERCOT's daily median of hourly medians held a $21 to $38/MWh band every day of the record week; only the worst-hour tail moved, and it fell back within three days.

Log-scale chart of daily summaries of hourly nodal-price distributions across roughly 1,114 ERCOT settlement points in the real-time market, July 14 to 25, 2026. The daily median of hourly medians holds a $21 to $38 per MWh band every day, including the two highest-load days. The day's highest hourly nodal P95 reached $362 on the record-load day, July 22, and fell back near $47 by July 25, and the highest single settlement-point interval reaches about $2,344. An inset tracks the real-time average across ERCOT's seven trading hubs over the same window.

This figure is from the ERCOT July 2026 heat-wave case study, a primary-source reconstruction of an all-time demand record crossed on a week without record heat, and what the public record does and does not show about it.
