Experts worry most about the grid’s nervous system: 2,000 extra-high voltage transformers. They’re 200- and 300-ton behemoths, individually engineered to meet specific power demands, and on average, they’re 40 years old. Notwithstanding the fact that 85 percent of transformers are imported, the U.S. Department of Energy says it takes between 5 and 16 months to replace a single one. According to the U.S. Federal Energy Regulatory Committee, an attack that destroyed nine of the 2,000 transformers would “cause a protracted nationwide blackout.” There’s no national cache of spare transformers.
