Super Bowl blackout under investigation


NEW ORLEANS — Who turned out the lights?

The day after the 34-minute blackout at the Super Bowl, the exact cause was unclear, although a couple of potential culprits had been ruled out.

It wasn’t Beyoncé’s electrifying halftime performance, said Doug Thornton, manager of the state-owned Superdome, since the singer had her own generator. And it apparently wasn’t a case of too much demand for power.

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.
