The cost of a Level 2 EV charger installation involves more than just the charger. You need to consider the capacity of your electrical panel, the distance between it and where you want your charger, and of course the permits needed to make an installation possible.
What Shapes Level 2 EV Charger Installation Costs in the Black Hills
Distance from Your Panel
This is arguably the biggest influence behind the cost of installation and should be one of the first things discussed when deciding on the placement of your charger. A shorter distance between your panel and charger generally costs less because you need less cable.
The Capacity of Your Electrical Panel
Level 2 EV chargers typically draw 30 to 50 amps while charging, so before you even think of getting start on installation, an electrician needs to calculate your home’s current electrical load. Older homes usually have smaller electrical services, and even a 100-amp service can be close to its capacity if the home is running several power-hungry appliances. You can either install a subpanel, or you can upgrade your service to accommodate the charger. Alternatively, you can install a load management device.
Even if your panel has enough capacity for a Level 2 charger, you still need a dedicated circuit sized for its electrical load. The circuit still needs to be rated for at least 125% of the charger’s maximum current to keep the wires from overheating. Where a simple installation may cost $60 to $150, more complex ones become more expensive.
Wiring Route and Conditions
Two homes with the same distance between panel and charger can have different installation costs, depending on how difficult the wiring route is.
It’s significantly easier to run a wire through an unfinished basement than it is to fish it through crawl spaces or lay it underground. A standard quote may leave out major construction such as trenching or extensive drywall work, so ask what your quote assumes.
The quality of your wiring matters as well. It needs to be correctly sized and rated for the charger’s electrical load. Undersized wire can overheat and create a fire risk, so this isn’t a place to cut corners.
Detached Garages and Outdoor Installs
Installing an EV charger in a detached garage or outdoors can add to the cost.
Detached garages require trenching or overhead cables, and usually the installation of a new subpanel.
Outdoor installations can cost more because the equipment and wiring need to be weatherproof, as do the fittings. Depending on your setup, you may also need an appropriate conduit, GFCI protection for receptacles, and longer wire runs. The final cost depends on the location of the charger and how the wiring is going to reach it.
Plug-In vs Hardwired
A NEMA 14-50 lets you plug a charger in and move it later but typically caps charging at 40 amps (9.6 kW). A hardwired charger connects directly to your electrical system, can deliver 19.2 kW with compatible equipment and a suitable electrical supply. The price difference is usually just $100 to $200, so it’s worth choosing on your needs rather than cost alone.
A few practical points apply to plug-in setups. You can swap chargers without calling an electrician, an outdoor outlet has to be GFCI protected and weatherproof, and some jurisdictions require hardwiring. A NEMA 14-50 outlet install runs $150 to $400. If you go plug-in with us, we use real EV-rated outlets rather than standard receptacles. Black Hills Energy’s rebate, covered below, accepts either setup for its listed charger.
Charger Amperage and Equipment
Depending on the model, a Level 2 charger can cost between $300 and $800, with bigger units often costing more to wire. The size of your charger will depend on what you need it for.
A 40-amp charger is a very practical choice for someone who mainly uses their EV to commute and chargers it overnight. A higher-amperage charger can replenish the battery faster, but only if your vehicle is designed to handle the rate. Your home also needs to be able to handle it. The capacity of your panel should be one of the first things you consider. Anything it has left to spare is the practical limit
Where the Money Goes
| Cost | Typical Range | Notes |
|---|---|---|
| Charger | $300 to $600 | Higher end units can reach $700 |
| Installation | Nationally $800 to $3,000 but the average across South Dakota is around $1,996 | This doesn’t include the charger, just the labor, wires, breaker, and conduit. |
| Permit and inspection | $50 to $800 nationally | This is set by your city or county. |
Some installers include the permit in their quote, while others don’t, so ask before you compare two bids. We pull the permit and schedule the inspection ourselves, and most residential installs wrap up in a single visit.
What the State Charges for Permits and Inspections
| Item | State fee |
|---|---|
| Wiring permit | $20 each |
| New circuit installation or alteration | $65 per circuit |
| Minimum inspection fee (applies when the calculated fee is below $150) | $150 |
| Service replacement, up to 200 amps | $130 plus new circuits |
| Service replacement, 201 to 400 amps | $163 plus new circuits |
| Reinspection | $150-per-hour |
| Late wiring permit (administrative fee) | $250 |
These are state fees. Rapid City runs its own Building Services Division, so inside city limits your permit and inspection may come through the city at its own rates. Your installer can tell you which applies to your address.
Rebates That Lower the Cost of an EV Charger Installation in the Black Hills
If Black Hills Energy is your supplier, you may qualify for a Black Hills Energy EV charger rebate of up to $500 toward the purchase and installation of a Level 2 charger. The 2026 program is narrow. The 2026 rebate form lists a single qualifying charger model, either plugged in (NEMA 6-50 or 14-50) or hardwired.
The charger has to connect to Wi-Fi, a qualified electrician has to install it and its dedicated circuit, and you have to pull any permits your city or county requires. Both the installation and your application have to be done by December 31, 2026. Rebates are offered on a first-come, first served-basis, and they can’t exceed what you actually spent. If you’re reading this after that date, check the program page for the current terms.
The federal 30C tax credit is off the table. Under the law as amended in 2025, it can’t be claimed for chargers placed in service after June 30, 2026, according to the IRS instructions.
If you’d rather spread the cost out, we offer Affirm financing for EV charger installations with 12, 24, or 36 month plans. Approval and terms go through Affirm.
How to Get a Quote You Can Compare
When getting a quote, ask for the charger, labor, materials, permit, and any panel work to be listed as separate line items. That’s the quickest way to see whether you’re paying for a charger or for a panel. And ask for a load calculation before anyone prices wires.
Wires R Us covers Rapid City, Sturgis, Spearfish, and the rest of the Black Hills. Send us the details of your installations and we’ll put together a written quote based on your actual panel and layout.
Common Questions
How much is an electrical permit for an EV charger in South Dakota?
The South Dakota Electrical Commission’s schedule, effective July 1, 2025, lists a $20 wiring permit and $65 per new circuit, with a $150 minimum inspection fee. Cities that run their own permit programs, including Rapid City, may charge at different rates, so confirm the fee for your address.
Will I need a panel upgrade for a Level 2 charger?
Not always. A load calculation shows whether your panel can carry a charger running for hours at a time. Older homes with electric ranges, hot tubs, electric water heaters, or electric heat are the most likely to need panel work first.
Is the federal EV charger tax credit still available?
No, the 30C credit can’t be claimed for chargers placed in service after June 30, 2026.
