The secure and reliable delivery of electricity is a vital cornerstone of modern American society. In this three-part series about the vulnerabilities of our nation’s interconnected power grid, LtCol Oliver North and Chuck Holton investigate the threats facing our aging energy infrastructure.
In the first of this three-part series, Frontlines takes you to the scene of the unsolved April 16, 2013, attack on the Pacific Gas & Electric Metcalf transmission substation in California.
The attack began just before 1 a.m., 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.
