The state’s top utility regulator, Arizona Corporation Commission Chairman Bob Stump, wants electric companies to explain whether they are prepared to defend the electric grid against terrorist attacks.
The concern is prompted by an attack last April on an electrical substation in California. For 19 minutes, gunmen opened fire on the facility near San Jose and knocked out 17 transformers. Nobody was caught in the incident. Pacific Gas and Electric prevented a blackout by rerouting power.
Stump and fellow commissioner Robert Burns sent a letter last week to Arizona Public Service Co., Tucson Electric Power and UniSource Energy Services, Salt River Project, and the state’s electric cooperatives, asking them to respond to a list of questions regarding whether they are prepared for similar events.
