In 2015, EPB became the first PEER-certified municipal utility in the world. Established as an independent board of the City of Chattanooga in 1935, the Electric Power Board (EPB) serves 177,000 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.

Based on Lawrence Berkeley National Laboratory’s Interruption Cost Estimate Calculator, EPB’s improvements in reliability save approximately $40 million a year.
