EPB of Chattanooga, formerly known as the Electric Power Board of Chattanooga, is an American electric power distribution and telecommunications company owned by the city of Chattanooga, Tennessee. EPB serves nearly 180,000 homes and businesses in a 600-square mile area in the greater Chattanooga area and Hamilton County. In 2010, EPB was the first company in the United States to offer 1 Gbit/s high-speed internet, over 200 times faster than the national average over a fiber optic network. As a result, Chattanooga has been called "Gig City®" and held up as a national model for deploying the world's fastest internet and America's most advanced Smart Grid electric distribution system. On October 15, 2015, Chattanooga implemented the world's first community-wide 10-gig Internet service, available to all homes and businesses in EPB's service area.
