Grid Attack: WSJ
How America Could Go Dark
by Rebecca Smith
An early morning passerby phoned in a report of two people with flashlights prowling inside the fence of an electrical substation in Bakersfield, Calif. Utility workers from Pacific Gas & Electric Co. later found cut transformer wires.
The following night, someone slashed wires to alarms and critical equipment at the substation, which serves 16,700 customers. A guard surprised one intruder, who fled. Police never learned the identities or motive of the burglars.
