An advisory was issued for flights to expect delays of 60 minutes or more until the situation is resolved. As of 1200Z, the ACC was still without commercial power. Limited power is being supplied by an old diesel generator. The new back-up power unit that was recently installed was severely damaged in the initial outage. Ops. Impact -- lots of delays.
