There are more than 3,300 power utilities and about 7,700 power plants that produce and distribute electricity to homes, businesses and other consumers. That electricity travels through more than 160,000 miles of high-voltage electric transmission lines that reach into every nook and cranny of the country.
Experts describe the nation’s electrical grid as a patchwork of utilities, with transmission and distribution facilities — some dating to the 1800s — that will ultimately break down unless hundreds of billions of dollars are invested.
