UPDATE AT 2:10 P.M.: A statement was released on behalf of the Las Vegas Convention and Visitors Authority, Consumer Technology Association and NV Energy.
Today at approximately 11:15 a.m., the Central Hall and South Hall bridge meeting rooms at the Las Vegas Convention Center lost power. Power in the south hall was restored within minutes, and power has now been fully restored to all areas. A preliminary assessment indicates that condensation from heavy rainfall caused a flashover on one of the facility’s transformers. We are grateful to NV Energy for their swift assistance, to our customers and their clients for their patience and to the staff for ensuring the safety and security of all attendees and exhibitors.
The two hours convention-goers were shut out of the Central Hall led to lost productivity.
Bruce Koenigsberg, in from Seattle, said he missed appointments that can't be rescheduled.
"It's almost like I'm going to have to extend my trip another day," he said. "I was going to fly back to Seattle Thursday night and now I'm going to have to pay money to go Friday night."
The possibility of staying another day also upset Koenigsberg because it would mean another day away from his family.
