Power outages at Las Vegas airport affected Terminal 1 and 3.
An attempted copper wire theft at an energy substation caused a temporary power outage on Monday.
The outage began at about 3:15 p.m. and affected 12 customers at its peak, the company said.
As of 6:15 p.m., one person was still affected by the outage, the company said. Its crews are working to restore power.
Harry Reid International Airport had two power outages on Monday. The first one at Terminal 3 lasted from 3:30 p.m. until it was restored at 5:18 p.m., according to an airport spokesperson.
The company did not disclose the location of the incident, but said that NV Energy facilities are often a target for copper theft.
The airport suffered another outage at 6:45 p.m., when all of the C gates in Terminal 1 lost power. The power was restored by 8 p.m., according to the airport. When power is out at the airport, the electronic doors to planes lock and flights can be delayed.
