[3] In 2010, EPB was the first company in the United States to offer 1 Gbit/s high-speed internet over a fiber optic network, over 200 times faster than the national average.

[4] As a result, Chattanooga has been called "Gig City" and held up as a national model for deploying the world's fastest internet and the most advanced Smart Grid electric distribution system in the United States.

[32] In July 2020, EPB and its community partners announced HCS EdConnect, a program to provide the families of all economically challenged K–12 students with high-speed internet and a wireless router at no charge.

[33] In January 2021, an independent study conducted by Bento Lobo, Ph.D. of the University of Tennessee at Chattanooga, documented $2.69 billion in benefits to the community during the first ten years after EPB built the community-wide fiber optic network and advanced smart grid.

[42] As part of the government-owned infrastructure in Chattanooga, EPB functions as one of the community's first responders to ensure uninterrupted fiber optic and electric power service in the event of natural disasters.

EPB leveraged mutual aid agreements to bring more than 1,500 utility workers from eight states to restore services for the remaining affected customers.

In addition to the utility crews, EPB office employees also assisted by volunteering to distribute food and protective gear and coordinate the staging of reconstruction materials.

[45] In July 2020, EPB joined Hamilton County Schools in launching HCS Ed Connect to provide home-based internet to all K-12 students and their families at no charge.

[47] EPB engaged TVA in matching donations to United Way of Greater Chattanooga's Restore Hope Fund to support individuals and families experiencing financial strain due to COVID-19, resulting in a total contribution of more than $785,000.

The donation of the face coverings benefitted five schools located in Hamilton County and was initiated by an Economic Recovery Group commissioned by Tennessee state Governor, Bill Lee.
