What caused power outage at Super Bowl: Is 'abnormality' the whole story? (+video)
“Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue,” the statement continues. “Backup generators kicked in immediately as designed. Entergy and SMG subsequently coordinated start up procedures, ensuring that full power was safely restored to the Superdome.”
The obvious follow-on question is, What caused that abnormality?
The statement said Entergy and SMG are continuing to investigate for an answer on that “root cause.”
The fault-sensing equipment, the companies added, operated right where Superdome equipment intersects with Entergy's feed of incoming power. An FBI special agent, quoted by The Associated Press, said terrorism didn't cause the power problem.
The halftime show and the CBS broadcast were operating on their own power sources, separate from the rest of the stadium, a representative of SMG said Monday morning, according to the news site NOLA.com, which covers the New Orleans area. Separately, the Louisiana Stadium and Exposition District said the blackout was unrelated to emergency electrical work that was done at the Superdome in December, the news website reported.
The incident was relatively brief, as power outages go. But it occurred at an important time and place – right in the stadium where the National Football League (NFL) championship was at stake, with millions of Americans watching, and with the momentum resting heavily with the Baltimore Ravens.
