St. Louis EV ownership is growing fast — and so is demand for home Level 2 chargers. Here's everything you need to know about EV charger installation costs, panel requirements, and available rebates in Missouri.
EV Charger Installation Cost in St. Louis
| Scenario | Estimated Cost |
|---|---|
| Simple install (panel has capacity, short run) | $400 – $800 |
| Standard install (moderate wiring run) | $800 – $1,500 |
| Complex install (long run, conduit, outdoor) | $1,500 – $2,500 |
| Panel upgrade required + charger install | $2,500 – $5,000 |
The charger hardware itself (a Level 2 EVSE like a ChargePoint, Grizzl-E, or Tesla Wall Connector) typically costs $300 to $700 in addition to installation labor.
What Affects the Cost
Distance from Panel to Garage
The further the charger is from your electrical panel, the more wire and conduit is needed — and the higher the labor cost. A garage directly adjacent to your panel is a simple job. A detached garage on the other side of the house requires trenching or conduit runs.
Panel Capacity
A Level 2 charger needs a dedicated 240V circuit — typically 40 to 60 amps. If your panel doesn't have capacity to spare, you'll need a panel upgrade first. We always assess your panel before quoting a charger installation so there are no surprises.
Permit Requirements
EV charger installation requires a permit in St. Louis City, St. Louis County, and most surrounding municipalities. The permit and inspection is included in our quotes.
Ameren Missouri EV Rebates
Ameren Missouri offers rebates for qualifying Level 2 EV charger installations. Rebate amounts vary and eligibility depends on your account and the charger equipment. We'll help you identify what rebates you qualify for as part of the quote process.
💡 Good to know: A Level 2 charger adds roughly 25 miles of range per hour of charging. For most St. Louis commuters, overnight charging fully replenishes any daily driving. A Level 1 (standard 120V outlet) adds only 4-5 miles per hour — functional but slow.
