Power has since been restored to the airport, but inbound flights had been held at their outbound airports,

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

“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.”
