Power Back On in South Florida

Floridians saw the light again last evening when power was restored after equipment failure at a single Miami substation caused a blackout which dominoed across South Florida, leaving millions without power for several hours. Most homes were back on the grid before nightfall, but why a single substation's failure could have such a devastating impact remains a mystery, reports the Miami Herald.

Both reactors at the Turkey Point nuclear power station shut down as a safety measure, triggering incorrect reports that the outtage triggered the blackout. "This failure is in no way a safety issue,"  said a spokeswoman for Florida Power & Light. "The system performed as it should have. Our system is designed to protect the system."
