Silicon Valley’s House members want an update on the Department of Homeland Security’s investigation of the sniper attack on PG&E’s Metcalf power substation last April.
“Although the damage from the Metcalf incident was largely contained, the potential for a catastrophic attack impacting both our electric grid and communications infrastructure is evident,” the lawmakers wrote. “As we understand it, rolling blackouts throughout our region were narrowly averted. The Metcalf attack, while sophisticated, was relatively small. A larger attack is not difficult to imagine and the effects could be crippling.”
Somebody fired rifle rounds last April to take out 17 transformers and 6 circuit breakers, causing $15.4 million in damage at the facility near Coyote Ranch Road in South San Jose. Nobody was hurt and nobody lost power, but circumstances suggest it was a planned attack.
Given the Bay Area’s high concentration of Fortune 500 companies, patent generation and economic productivity, a successful attack on the area’s power grid “would impact not only our region but our country as a whole,” they wrote.
The lawmakers asked Johnson to respond by March 14 with a summary of his department’s work on the incident, including the initial emergency response; work since the incident on improving protection of critical infrastructure, emergency mitigation and coordination with other agencies; recommendations for more improvements; and guidance on whether any congressional action is needed.
