EPB, also known as the Electric Power Board of Chattanooga, is an electricity distribution and telecommunications company owned by the city of Chattanooga, Tennessee. 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. 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.
In 1935, an act of the Tennessee Legislature established EPB as an independent, board of the City of Chattanooga to provide electric power to the Greater Chattanooga area. Today, EPB remains one of the largest publicly owned electric power distributors in the country. EPB serves more than 170,000 homes and businesses in a area that includes greater Chattanooga and Hamilton County, portions of surrounding Southeastern Tennessee counties and areas of north Georgia.
