NEW ORLEANS —
Entergy and the company that manages the Superdome, SMG, said Sunday that an "abnormality" occurred where stadium equipment intersects with an Entergy electric feed, causing a breaker to create the outage. It remained unclear Monday exactly what the abnormality was or why it occurred.
The lights-out championship game proved an embarrassment for New Orleans just when it was hoping to show the rest of the world how far it has come since Hurricane Katrina in 2005. But many fans were forgiving, and officials expressed confidence that the episode wouldn't hurt the city's hopes of hosting the championship again.
To New Orleans' relief, NFL Commissioner Roger Goodell said the city did a "terrific" job hosting its first pro football championship in the post-Katrina era.
"I fully expect that we will be back here for Super Bowls," he said, noting a backup power system was poised to kick in but wasn't needed once the lights came back.
Fans watching from home weren't deterred, either. An estimated 108.4 million television viewers saw the Baltimore Ravens beat the San Francisco 49ers 34-31, making it the third most-viewed program in television history. Both the 2010 and 2011 games hit the 111 million mark.
As for possible culprits, it couldn't be blamed on a case of too much demand for power.
Meters showed the 76,000-seat stadium was drawing no more electricity than it does during a typical New Orleans Saints game, according to Doug Thornton, the Superdome manager.
He also ruled out Beyonce's electrifying halftime performance. She brought along her own generator.
Officials with the utility and the Superdome were quick to note that an NFL game, the Sugar Bowl and another bowl game were played there in recent weeks with no apparent problems.
Determining the cause will probably take days, according to Dennis Dawsey, a vice president for distribution and transmission for Entergy. He said the makers of some of the switching gear have been brought in to help figure out what happened.
