Electrical Panel Upgrades for EV Chargers in Chattanooga

Many Chattanooga homes, especially in older neighborhoods like North Shore, St. Elmo, Southside, Highland Park, have 100-amp electrical service that cannot safely support a Level 2 EV charger. A panel upgrade resolves this, and the combined project can often be completed in one or two visits.

Do You Need an Upgrade?

Check your main breaker, if it says 100A, you almost certainly need an upgrade. If it says 200A with open slots, you likely don't. Full panel assessment guide →

Cost in Chattanooga

A 100A to 200A panel upgrade in Chattanooga runs $2,000–$3,500 including labor, materials, permit, and inspection. Combined with the Level 2 charger installation, total project cost is typically $2,500–$4,500.

After the Panel Upgrade

Once your panel is upgraded to 200A, Level 2 charger installation is typically done in the same visit or a follow-up appointment. EPB residential customers are eligible for a $50 rebate on the charger installation. Check the EPB rebate and Night Shift TOU guide to see what you'll qualify for after installation.
