Chattanooga

Chattanooga's real export is not scenery. It is a city-owned utility that turned power lines into local industrial policy. Set along the Tennessee River at 208 metres above sea level, Chattanooga now has an estimated 191,496 residents, up from the 181,099 carried in the GeoNames stub. City Hall is happy to market the place as North America's first National Park City, a label it won after a campaign backed by more than 5,600 signatures. That brand is real. It is just not the deepest explanation for the city's rise.

The Wikipedia gap is EPB. The municipal utility's 2025 community-benefit study says its fiber network and automated grid generated $5.3 billion in value from 2011 through 2024 and supported 10,420 jobs, or 31 percent of all jobs created locally during that period. The same report says the system prevented 417.7 million minutes of outages and helped customers avoid more than $945 million in outage-related costs. Chattanooga matters because it built a piece of civic infrastructure that behaves like a keystone species: remove it, and the local ecosystem of startups, manufacturers, researchers, and remote workers looks very different.

That infrastructure keeps compounding because it rewrites the city's habitat. EPB's own release quotes Mayor Tim Kelly saying the network turned Chattanooga into a magnet for tech startups, remote workers, and researchers. Those arrivals then justify more capacity, more experimentation, and more prestige, which is positive feedback loops in plain sight. What looks from the outside like a pretty mid-sized river city is actually a long-running niche-construction project in which a public utility reshaped the conditions under which firms can live and grow.

Biologically, Chattanooga resembles a termite mound. A termite mound is climate-control infrastructure disguised as dirt, regulating temperature and airflow so the colony can do more work than the outside environment would normally allow. Chattanooga does the urban version with electricity and fiber. The management lesson is blunt: if you want durable economic advantage, build the habitat that makes better performance normal. Brand helps. Infrastructure decides.
