With 11,157 EVs in Williamson County, Franklin and Brentwood are the epicenter of Tennessee EV adoption. The county’s high-income households and newer housing stock make it ideal for EV ownership — and the easiest place in the state to install a charger.
Why Franklin Homes Are Charger-Ready
Franklin and Brentwood’s housing stock is predominantly newer construction with 200-amp electrical panels and available breaker space. This is the easiest scenario for EV charger installation:
- 200A panel = 40kW+ of capacity
- Typical Franklin home uses 15–25kW of that capacity
- A 48A EV charger adds 11.5kW — fits with room to spare
- Result: Tier 1 install ($500–$1,500), no panel upgrade
Franklin is served by Nashville Electric Service (NES) and Middle Tennessee Electric (MTE). Both utilities support EV charging infrastructure across the region.
