The study’s results have been known for months to select people in federal agencies, Congress and the White House, but were reported publicly for the first time Wednesday. The WSJ did not publish a list of the 30 most critical substations identified by the FERC study. Electric substations play a vital role in keeping the electric grid humming by boosting voltage for long-distance travel and then transforming it to usable levels upon arrival. On a hot summer day, with the grid operating at high capacity, FERC found that taking out the right amount of substations could lead to a national blackout lasting weeks or even months. “This would be an event of unprecedented proportions,” said Ross Baldick, an electrical engineering professor at the University of Texas. One particularly troubling memo reviewed by the _Journal_ described a scenario in which a highly-coordinated but relatively small scale attack could send the country into a long-term literal dark age. “Destroy nine interconnection substations and a transformer manufacturer and the entire United States grid would be down for at least 18 months, probably longer,” the memo said. Some federal officials, including David Ortiz, deputy assistant secretary for the Department of Energy, said the FERC study may overstate the grid’s vulnerability. Federal rules don’t currently regulate the security of electric substations except for those at nuclear power plants, the _Journal_ reports. Utilities have been given until June to propose new security standards for vital facilities. \[[The Wall Street _Journal_](http://online.wsj.com/news/articles/SB10001424052702304020104579433670284061220)\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/23281/report-u-s-could-be-plunged-into-blackout-by-minimal-attacks/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/23281/report-u-s-could-be-plunged-into-blackout-by-minimal-attacks/"},"headline":"Report: U.S. Could Be Plunged Into Blackout By Minimal Attacks","datePublished":"2014-03-13T14:29:15.000Z","dateModified":"2026-02-21T06:45:15.785Z","description":"A major federal study on the vulnerability of the U.S. electric grid reportedly finds that taking out just nine of the country's 55,000 electric-transmission substations—on a hot day when they're stressed—could provoke a national blackout","url":"https://time.com/23281/report-u-s-could-be-plunged-into-blackout-by-minimal-attacks/","keywords":["Nuclear","energy","Security"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb3ab01c50187d9b1/69868548cd804d606ccc9b5d/electrical-grid.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Denver Nicks","jobTitle":null,"url":"https://time.com/author/denver-nicks/"}],"articleSection":"Politics","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb3ab01c50187d9b1/69868548cd804d606ccc9b5d/electrical-grid.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Transformers at an Electrical Substation","caption":"Transformers at an Electrical Substation","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/politics/","name":"Politics"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/23281/report-u-s-could-be-plunged-into-blackout-by-minimal-attacks/","name":"Report: U.S. Could Be Plunged Into Blackout By Minimal Attacks"}}]}] ```
