Alert |
Notification of Real-Time Market (RTM) prices under investigation. Due to an issue during routine maintenance of the Emergency Management System (EMS), post-contingency overloads for Generic Transmission Constraints (GTCs) were incorrectly being considered in SCED for Operating Days (ODs) 3/28/2025 and 3/29/2025. ERCOT is currently investigating the impact to RTM prices. Should a price correction be warranted, a follow-up Market Notice will be issued with more details. The deadline for correcting prices before they become final is 4/1/2025 at 4PM for OD 3/28/2025 and 4/2/2025 at 4pm for OD 3/28/2025. |
