Attack on electric grid raises alarm

Attack on electric grid raises alarm - latimes.com:A 2013 attack on an electric substation near San Jose that nearly knocked out Silicon Valley's power supply was initially downplayed as vandalism by Pacific Gas & Electric Co., the facility's owner. Gunfire from semiautomatic weapons did extensive damage to 17 transformers that sent grid operators scrambling to avoid a blackout. But this week, a former top power regulator offered a far more ominous interpretation: The attack was terrorism, he said, and if circumstances had been just a little different, it could have been disastrous.
