Power Restored at Denver Airport After Outage Halts Trains and Triggers Ground Stop

Utility officials say a piece of equipment shut off during transformer work at a substation serving the airport.

Overview

  • The disruption began around 9:20 a.m. Wednesday, disabling key systems and prompting the FAA to implement a ground stop for incoming flights.
  • Power returned at about 11:04 a.m., the ground stop ended near 11:35 a.m., and officials reported operations stabilizing shortly after noon.
  • By mid-afternoon, FlightAware recorded roughly 272 departing and 217 arriving delays along with eight cancellations as carriers recovered.
  • The airport’s train between the terminal and concourses was out of service, boarding paused on multiple flights, and restrooms and intercoms were affected, according to passengers.
  • The outage hit during peak spring-break travel, worsening crowding as airlines and the airport worked through backlogs.
