The deepest mystery in the energy world is a weekend shooting attack that damaged a pair of electric substations in Moore County, N.C. — a reminder that the power grid faces dangers from physical attacks, not just cyber ones. About 34,000 customers are still without power after enduring frigid temperatures following Saturday's shootings, which law enforcement officials characterized as deliberate. Duke Energy Corp. has said outages could last until Thursday , and officials say repairs could be complex. Meanwhile, the shooter or shooters remain unknown, as does the motive. (Theories abound online, including people noting that the outage struck during a drag show.) Whatever the reason for it, energy experts say the attack exposes a weakness in grid security. "It clearly indicates that we're still vulnerable and we haven't taken sufficient action to address the vulnerabilities," said Jon Wellinghoff, a former chair of the Federal Energy Regulatory Commission, which oversees rules governing the grid. While government and industry have recently focused on hardening the grid against cybersecurity threats and extreme weather from climate change, physical security hasn't gotten quite the same attention. The last time federal regulators took major action on this type of threat was in 2013, after unknown attackers shot a high-voltage Pacific Gas & Electric Co. substation in Coyote, Calif. The attack caused millions of dollars in damage, though a quick response from grid operators meant the power stayed on. The Department of Homeland Security suspected an "insider" was involved , but no one was ever charged. The incident spurred FERC to set new standards for electrical infrastructure security, including shielding high-voltage transformers. Certain kinds of transformers are in short supply nationwide , with wait times for some supplies stretching as long as two to three years, making them an especially worrying target. Tom Alrich, an electric grid security consultant, said the protections resulting from the FERC action were rigorous — and expensive. Wellinghoff, who was FERC chair at the time, believes at least one of the substations damaged in Saturday's attack should be subject to those regulations. But Alrich said they are probably not covered by the standard because their voltages are too low. "However, even if the N.C. substations had been in scope, it's doubtful these attacks could have been prevented, although they might have had less impact," Alrich said.
