According to federal law enforcement, five other electricity substations in the United States have been attacked.
the news broke after a memo was released to the public following the attack in Moore County, North Carolina that caused a crippling outage.
Besides, North Carolina attacks have occurred in Washington and Oregon.
The memo also revealed that all the attacks seem to be similar.
“In recent attacks, criminal actors bypassed security fences by cutting the fence links, lighting nearby fires, shooting equipment from a distance or throwing objects over the fence and on to equipment,” the memo said.
From the Dailymail:
A spokesperson for BPA, Douglas Johnson, said the company suffered a ‘deliberate physical attack’ at a Clackamas, Oregon substation over Thanksgiving and that fencing and equipment were damaged.
He added that the company is ‘actively cooperating with the FBI on this incident and has encouraged other utilities throughout the region to increase their vigilance and report any suspicious or similar activity to law enforcement.’
He did not offer specific details about the damage to the substation’s equipment, only that the cost of its repair would be passed on to customers of the public utility.
The FBI would not confirm or deny that it is investigating the attacks, though the companies said they are cooperating with a federal investigation.
Gerald Tracy, the media engagement program manager at Puget Sound Energy said that he was unable to ‘comment on the incidents because they are both an ongoing investigation involving the FBI.’
Two PSE substations were attacked in late November, though it is unknown which ones or to what extent they were damaged.
In South Carolina residents reported hearing gunshots newar the Wateree Hydro Station.
“No individuals were harmed. There are no outages reported. There is no known property damage at this time. We are working closely with the FBI on this issue,” read a statement from Duke energy.
