Power outage at DEN 18 March 2026 (recovering)
 
Currently in a long lane of planes holding at DEN due to a power outage in the terminal.
No radio comms, no trains running, nobody able to get to arrival gates.
It's complete bedlam here.
Anyone in the terminal now?

Starting to get media coverage:


The Federal Aviation Administration said that a ground stop was issued for 9:54 a.m. to 11:30 a.m., meaning all flights departing to Denver are grounded due to the equipment outages. ​​​​​​​

We are taxiing to the gate now so I guess ground stop was lifted?
Our FO said power is being restored now.

Interesting that it went dark. There are two independent 25kV feeds to separate substations at DIA plus they have on-premise diesel backup.

It was only a partial outage.

I use it as an industry term for losing power, not in the literal sense :D

They were working on the elusive DEN PL and tripped a circuit breaker! :D

Those DEN trains sure go down a lot. Seems to happen every couple weeks.

Dumpster fire at DEN A concourse around 1130

What a mess. Took about 40 minutes to go from B45 to A25.
But trains running now.
UCs are all on auxiliary power so no food, only booze. And many escalators not running.

I remember reading about why there is no alternative walkway for the trains. Maybe it was budget?

Jaysonb22 Mar 18, 2026 12:48 pm

I called the 1K line to discuss something about a past flight and was on hold for a long time. This now makes sense as to why. I think I'll just call back later.

aisleorwindow Mar 18, 2026 1:02 pm

Seems like things are slowly getting back to normal now. Just pushed back from the gate - only about 45 minutes late which honestly is better than I thought it was going to be.

Technology is infallible! There is no need for alternatives! The trains will never go down!

(It seems like even when the rest of the airport has power about 1 in 3 trips through DEN include some kind of train drama... I'm just very happy both of my DEN transits this year included a premium services agent making the B-to-A connection not suck)
