LONG DESCRIPTION: Some of ERCOT’s informational dashboards and displays on ERCOT.com will be affected by the beginning of Daylight Saving Time (DST) on Sunday, March 10, 2024.

The System-Wide Prices dashboard line chart will present a distorted view due to the loss of the 2:00 a.m. hour on Sunday, March 10.
The Real-Time Settlement Point Prices display will display a 0200 (2:00 a.m.) interval ending that should instead be labeled 0300 (3:00 a.m.). The associated data appearing on the incorrectly labeled 0200 line of the chart will be for the 0300 ending interval.
