'Military-Style' Raid on California Power Station Spooks U.S.
When U.S. officials warn about "attacks" on electric power facilities these days, the first thing that comes to mind is probably a computer hacker trying to shut the lights off in a city with malware. But a more traditional attack on a power station in California has U.S. officials puzzled and worried about the physical security of the the electrical grid--from attackers who come in with guns blazing.
Around 1:00 AM on April 16, at least one individual (possibly two) entered two different manholes at the PG&E Metcalf power substation, southeast of San Jose, and cut fiber cables in the area around the substation. That knocked out some local 911 services, landline service to the substation, and cell phone service in the area, a senior U.S. intelligence official told Foreign Policy. The intruder(s) then fired more than 100 rounds from what two officials described as a high-powered rifle at several transformers in the facility. Ten transformers were damaged in one area of the facility, and three transformer banks -- or groups of transformers -- were hit in another, according to a PG&E spokesman.
Cooling oil then leaked from a transformer bank, causing the transformers to overheat and shut down. State regulators urged customers in the area to conserve energy over the following days, but there was no long-term damage reported at the facility and there were no major power outages. There were no injuries reported. That was the good news. The bad news is that officials don't know who the shooter(s) were, and most importantly, whether further attacks are planned.
Black Blade: Seems that any "conventional" attack on the grid could be devastating in the immediate to intermediate term for a determined terrorist. Maybe even a criminal who wished to overburden law enforcement for a period of time while engaging in some other activity as well. A lot of reasons but also shows how exposed and how vulnerable the power grid is when you read stories about some "vandalism" on critical infrastructure. I keep a couple back up generators and a few flashlights and lanterns on hand as well. It has all come in quite handy during periodic blizzards when the grid goes down.
