Power Consultant Offers Explanation For San Diego Blackout

Doesn't the electric company know about redundancy? Backup of a backup of a backup.

Main: Main grid
Backup 1: Will replace main grid if it goes down. Main will be repaired. Backup 2 is waiting in case Backup 1 fails.
Backup 2: Will replace main and backup 1 if they both go down. Repairs to Main should be near completion. Switch to Main when it is repaired. Backup 1 and Backup 2 go on hold again serving only the low-use areas.

Now that would be 21st century engineering.
