Lawmakers are pushing to impose federal standards for protecting the country's electric grid from attack in the wake of a new report about a sniper assault on a California electrical substation last year that has raised fears the power grid is vulnerable to terrorism.
The Wall Street Journal reported Thursday that Sen. Dianne Feinstein, D-Calif., said she and fellow senators plan to ask the Federal Energy Regulatory Commission, which has jurisdiction over the electric grid's reliability, to "set minimum security standards for critical substations."
The April 16, 2013 the attack on Pacific Gas & Electric’s Metcalf transmission substation involved snipping AT&T fiber-optic lines to knock out phone and 911 service, and firing shots into a PG&E substation, causing outages. The assault had not been widely publicized until The Wall Street Journal reported new details in a story on Wednesday.
The FBI is the lead agency in the investigation and an agency spokesman told the newspaper it doesn’t think the incident was a terror attack. However, Jon Wellinghoff, chairman of the Federal Energy Regulatory Commission at the time, called it "the most significant incident of domestic terrorism involving the U.S. power grid that has ever occurred."
