Lights flickered and computer and television screens went offline Tuesday afternoon as the San Antonio International Airport experienced a loss of power around lunchtime.

The electricity came back on just before 1 p.m., according to CPS Energy’s Twitter account, but not before a pause in operations caused minimal delays in travel.

“There was a twenty minute interruption of airport wide services yesterday due to the power outage at San Antonio International Airport (SAT) that included a temporary stoppage of TSA screening,” spokeswoman Evelyn Bailey said in an email Wednesday. “The airport suffered no long term impact.”

The airport lost power just before noon on Tuesday, spokesman Rich Stinson said. The power outage impacted “all operations,” according to the airport’s Twitter.

Backup generators kicked in soon after the power went out, Stinson said. Airport officials were working with CPS Energy to determine the cause of the outage.

CPS Energy spokeswoman Melissa Sorola confirmed that damaged equipment on West Sunset Road and Jones-Maltsberger Road caused the power outage to the airport.

A third-party contractor doing their own work damaged CPS electrical lines, Sorola said Wednesday. The contractor was not working on CPS lines, she added.

About 500 other businesses and residential homes also lost power from the same incident, she said. All of those buildings had their power restored as of 2:15 p.m Tuesday.

CPS crews were still on West Sunset and Jones-Maltsberger roads at 1 p.m. Tuesday to finalize repairs on the damaged CPS Energy equipment.
