There was a brief electrical fire at our substation on 20th Avenue & 32nd Street in Astoria this evening, which caused a transmission dip in the area. All power lines serving the area are in service and the system is stable. Photo: Michael Friedl, New York Times pic.twitter.com/vq2Ao46rhk — Con Edison (@ConEdison) December 28, 2018

﻿Original report:

Electricity flickered off in some homes in the neighborhood, but there was a complete blackout at LaGuardia Airport.

Power has since been restored to the airport, but inbound flights had been held at their outbound airports, according to WNBC. KABC reported that a ground stop was issued by the FAA, but runways have since appeared to be back up and running.

"Due to a power failure at #LGA, please allow extra time when coming to the airport," the facility said in a tweet.

The airport also said that travelers should check with individual carriers about flight statuses.

"There was a brief electrical fire at our substation in Astoria which involved some electrical transformers and caused a transmission dip in the area," Con Edison said in a tweet. "We're currently investigating the cause of the incident."

New York Mayor Bill de Blasio said there is no fire currently and no injuries, but there are delays on the 7 train subway.
