- The WSJ profiles how the U.S. electricity grid is vulnerable to attacks on its transformers, which are the "glue" that holds the network together.
- Few companies make transformers in the U.S., and the equipment can take over a year to produce and months to ship.
- An assault on enough of the country's biggest 2,000 transformers could cause extended blackouts. Last year, a gun attack on 17 large PG&E Corp transformers took a California substation off line.
- "With a couple dollar bullets, you can take out a transformer worth millions of dollars," said Steve Newman, vice president of Delta Star, a supplier of the products.
