During the evening of February 3, 2013, play of Super Bowl XLVII between the San Francisco 49ers and the Baltimore Ravens was interrupted during the third quarter for approximately 34 minutes due to a partial loss of electrical power. At the time of the power loss, the electrical load (current) was rebounding after a significant reduction during the half-time show. Current levels had just exceeded highs encountered during the second quarter, prior to the half-time show, when a switch on the 13.8 kV system opened, disconnecting the west feeder between the utility, Entergy New Orleans Inc (ENOI), and the Superdome.
