Power At DIA Now Restored After Causing Flight Delays & Headaches

DENVER (CBS4) - A power outage at Denver International Airport caused flight delays on Wednesday afternoon. The FAA lifted a ground stop for all arriving flights at around 4 p.m.

DIA says power was restored at around the same time.

Officials tell CBS4 say the trains between TSA and the gates were still operating during the power outage. CBS4 confirmed most of Concourse B was without power, but started showing signs of life at around 3:30 p.m.

Departures were also returning to normal, but the airport said delays could linger.

DIA officials told CBS4 it does not appear the problem was on DIA's property. They say their "backup generators all worked, but the issue was with the redundant feed on Xcel Energy's side," adding that it's rare to have a full power outage due to the redundant feed and backup generators.

About 80 flights were impacted, out of about 1,700 that were operative on Wednesday.

DIA asks passengers to check with their airline for flight information.
