The U.S. could suffer a coast-to-coast blackout if saboteurs knocked out just nine of the country's 55,000 electric-transmission substations on a scorching summer day, according to a previously unreported federal analysis.
The study by the Federal Energy Regulatory Commission concluded that coordinated attacks in each of the nation's three separate electric systems could cause the entire power network to collapse, people familiar with the research said.
A small number of the country's substations play an outsize role in keeping power flowing across large regions. The FERC analysis indicates that knocking out nine of those key substations could plunge the country into darkness for weeks, if not months.
"This would be an event of unprecedented proportions," said Ross Baldick, a professor of electrical engineering at the University of Texas at Austin.
No federal rules require utilities to protect vital substations except those at nuclear power plants. Regulators recently said they would consider imposing security standards.
FERC last year used software to model the electric system's performance under the stress of losing important substations. The substations use large power transformers to boost the voltage of electricity so it can move long distances and then to reduce the voltage to a usable level as the electricity nears homes and businesses.
The agency's so-called power-flow analysis found that different sets of nine big substations produced similar results. The Wall Street Journal isn't publishing the list of 30 critical substations studied by FERC. The commission declined to discuss the analysis or to release its contents.

The study's results have been known for months by people at federal agencies, Congress and the White House, who were briefed by then-FERC Chairman Jon Wellinghoff and others at the commission. As reported by the Journal last month, Mr. Wellinghoff was concerned about a shooting attack on a California substation last April, which he said could be a dress rehearsal for additional assaults.Read the full story HERE.

Thanks for bringing this to their attention. *sarcasm*

That attack in California was probably a test run. Most folks don't realize how bad it is to be without electricity for an extended period ... UNTIL IT HAPPENS, and it isn't nice.
Making sure we're not vulnerable to a large scale blackout NEEDS TO BE MADE A PRIORITY.
That attack in CA barely made the radar screen. We are just sitting ducks because it's going to happen probably sooner than later.
