The power failure was confined to terminals B and C, and it affected outgoing AA, DL, UA, and US flights. I didn't hear anything about inbound flights being delayed. I checked the FAA delay site several times, but it kept showing DCA as having no delays. The media said delays at the ticket counters continued throughout the day, but the security checkpoints weren't affected.
The failure was caused by a fire at a nearby electrical sub-station.
For some reason power failures happen at DCA on a regular basis.
