So You Want a Home EV Charger: Here's Exactly What to Do
From panel check to EPB's Night Shift TOU plan, every step a Chattanooga homeowner needs, in order.
Getting a home EV charger installed in Chattanooga takes about 10 steps, from checking your electrical panel to enrolling in EPB's Night Shift plan. Most homeowners can go from zero to charging in 2 to 3 weeks. The install is half a day. What takes longer is finding a licensed electrician, getting the permit filed, and scheduling the inspection. Here's the full sequence, with specifics on where Chattanooga homes tend to run into panel or conduit complications, what EPB's rebate requires, and how the Night Shift TOU plan actually works.
Step 1: Decide Between Level 1 and Level 2
Level 1 is the cable that came with your car, plugged into a standard 120V outlet. It adds 3 to 5 miles of range per hour. If your commute is genuinely short and you plug in every single night without fail, it's technically workable. Most people find it limiting within the first month.
Level 2 uses a dedicated 240V circuit and adds 20 to 30 miles per hour. Your car is full by morning. It's the right answer for almost every Chattanooga homeowner with a garage, and EPB's Night Shift rate makes overnight charging very cheap.
Step 2: Check Your Electrical Panel
Find your main panel (garage, basement, utility room, or exterior) and look at the main breaker. 200A with open slots is almost always fine for a new 50-amp EV circuit.
100A panels are more common in Chattanooga's older neighborhoods, including parts of North Shore, downtown-adjacent streets, Red Bank, and some older East Ridge housing stock. Those panels are often running close to capacity. Options are a panel upgrade (typically $1,200 to $2,500 in Chattanooga) or a load management device ($200 to $400). Homes on Signal Mountain, Lookout Mountain, or in newer parts of Hixson and Hamilton County usually have 200A. Your electrician checks this at the quote visit.
Step 3: Choose Your Charger
Four questions narrow it down:
- Tesla or non-Tesla? Teslas work with the Tesla Wall Connector or any J1772 charger. All other EVs need J1772.
- Hardwired or plug-in? A 14-50 outlet lets you swap chargers later. Hardwired is cleaner. Both are code-compliant.
- Smart (Wi-Fi) or basic? A smart charger lets you schedule charging for EPB's Night Shift window (9PM to 6AM). Worth it here.
- EPB rebate requirements? Check epb.com for currently qualifying models before purchasing to ensure you get the $50 rebate.
See the EPB programs guide for currently qualifying charger models and rebate details.
Step 4: Check the EPB Rebate and Night Shift Plan
EPB offers $50 back on qualifying Level 2 charger installations. It's not a huge amount, but the Night Shift TOU plan is where EPB's real EV benefit sits. The plan offers lower rates during 9PM to 6AM. Configure your car or smart charger to charge during that window and you're paying off-peak rates for every kilowatt used for the car, night after night.
Both the rebate and the Night Shift plan are managed through EPB. Visit epb.com or call EPB to confirm current rebate requirements (the qualifying charger list and any submission deadlines) and to ask about enrolling in the Night Shift plan at the same time. See the EPB programs guide for details.
Step 5: Get Quotes from Licensed Electricians
Contact at least two Tennessee TDCI-licensed electricians. Ask directly: Are you licensed through Tennessee TDCI? Will you pull the permit, and is the fee in your quote? What does the quote actually cover?
A complete quote includes labor, materials, conduit, and the permit fee. For a standard attached garage in Chattanooga, expect $300 to $600. Homes on Signal Mountain or Lookout Mountain with longer conduit runs or steeper routing challenges may run higher. See what to ask before hiring an installer for the full checklist.
Step 6: Schedule Installation
Plan for a half-day block. Most attached garage installs take 2 to 4 hours. Tell your electrician where you park and where you'd like the charger mounted. If your home is on a hillside lot with a detached garage or a steep driveway, mention it during the quote so conduit routing is factored in.
Signal Mountain and Lookout Mountain homes occasionally have longer runs from the main panel to the garage than a flat-lot house. That adds labor and conduit cost, but it's not a reason to skip the install.
Step 7: Your Electrician Pulls the Permit
Tennessee requires an electrical permit for any new 240V circuit. If your address is in the City of Chattanooga, the permit comes from the City. If you're in unincorporated Hamilton County (Signal Mountain, Soddy-Daisy, or rural areas outside city limits), your electrician files with Hamilton County. They know the correct jurisdiction for your address.
Permits typically run $50 to $150. Most licensed electricians include this in their quote. Without a permit, you risk losing the EPB rebate eligibility and creating homeowner's insurance and resale issues.
Step 8: Pass the Electrical Inspection
After the install, your electrician schedules an inspection with the relevant authority (City of Chattanooga or Hamilton County). The inspector checks circuit sizing (50 amps), wiring to NEC standards, GFCI protection, and charger mounting. The inspection itself is 15 to 30 minutes. Getting on the schedule usually takes 2 to 5 business days in the Chattanooga area.
Your electrician handles scheduling and any re-inspection if something needs correction. You need to be home during the window.
Step 9: Submit Your EPB Rebate
After installation, submit the $50 EPB rebate at epb.com. Check the current submission deadline on EPB's website before your install (not after), so you know exactly how much time you have. You'll need your EPB account number and proof of charger purchase.
Fifty dollars isn't a huge amount, but there's no reason to miss it. Takes five minutes online. See the EPB programs guide for a step-by-step walkthrough of the submission.
Step 10: Enroll in EPB Night Shift TOU Plan
EPB's Night Shift plan offers lower rates from 9PM to 6AM. This is the most financially significant EPB benefit for EV owners, and it keeps paying you back every time you charge. The savings over standard rates depend on how many miles you drive, but for a driver covering 30 or more miles a day, the annual difference is real.
Contact EPB or visit epb.com to enroll in the Night Shift plan. Then configure your EV's charging timer or your smart charger's app to charge during the 9PM to 6AM window. Set it once and let it run. EPB's fiber-connected grid and competitive rates make Chattanooga one of the better cities in Tennessee for EV ownership costs.
Frequently Asked Questions
Usually 2 to 3 weeks. A few days for quotes, then a week or more for scheduling. Add a day or two for the permit, then 2 to 5 business days for the inspection. The install itself is half a day. Total is typically 2 to 3 weeks from first call.
EPB serves Chattanooga and Hamilton County, including Signal Mountain, Soddy-Daisy, Lookout Mountain, Red Bank, and East Ridge. Check your electricity bill to confirm EPB is your provider. If it says EPB, the rebate and Night Shift plan apply to you.
The EPB rebate is still available. The federal Section 30C tax credit expired for installs placed in service after June 30, 2026. If your install happened before that date and your address is in a qualifying census tract, you may still claim the federal credit when you file taxes. The two programs were always separate and stackable while both were active.
