Was an attack last April on an electric power station near San Jose, Calif., the work of vandals or something far more dangerous — domestic terrorism or a trial run by an individual or organization bent on damaging the nation's electric grid?
The Wall Street Journal, picking up from an earlier report by , explores that question Wednesday about what happened at PG&E Corp.'s Metcalf transmission substation — an event that has received relatively little attention until now.
The top of the Journal's story grabs your attention:
"The attack began just before 1 a.m. on April 16 last year, when someone slipped into an underground vault not far from a busy freeway and cut telephone cables.
"Within half an hour, snipers opened fire on a nearby electrical substation. Shooting for 19 minutes, they surgically knocked out 17 giant transformers that funnel power to Silicon Valley. A minute before a police car arrived, the shooters disappeared into the night.
"To avoid a blackout, electric-grid officials rerouted power around the site and asked power plants in Silicon Valley to produce more electricity. But it took utility workers 27 days to make repairs and bring the substation back to life."
