After becoming the first municipal utility to earn PEER certification in 2015, EPB continued to improve grid performance. In 2021, the utility earned Gold recertification, serving the largest number of customers through a PEER-certified municipal utility in the United States. Through their PEER recertification, Chattanooga has achieved the most resilient and reliable certified utility power grid in the country.

Established as an independent board of the City of Chattanooga in 1935, the Electric Power Board (EPB) serves 187,000 homes and businesses across greater Chattanooga, Tennessee and parts of North Georgia. One of America’s largest publicly‐owned electric power providers, EPB is committed to providing high quality, reliable energy as a means of promoting economic development and enhancing quality of life. Deliberate planning and investment in a robust and resilient grid is key to EPB’s strategy for supporting the area’s recruitment of new business, including clean high tech industry. PEER certification validates EPB’s accomplishments to date and demonstrates EPB and the City of Chattanooga’s commitment to sustainable power and continuous improvement.

For EPB, electric reliability is integral to delivering quality service to its customers. Supported by an innovative fiber optic network, EPB has laid the groundwork for an intelligent, redundant, and self‐healing grid that provides affordable power customers can count on. Approximately 94 percent of EPB customers can receive power through two or more distribution pathways. This means power can take alternative routes from the source to the customer in order to avoid downed or vulnerable sections of the grid. Additionally, all of EPB’s circuits can be fed from two or more sources, ensuring that customers receive power even if the primary source is interrupted.

Third party research found $2.69 billion in community benefit during the first ten years since EPB of Chattanooga built America’s first Gig-speed community-wide network and used it to establish the nation’s most advanced smart grid power distribution system." - Bento Lobo, Ph.D., head of the Department of Finance and Economics at the Rollins College of Business at the University of Tennessee at Chattanooga.
