What drives the cost
The charger itself is only part of the price. The bigger variables are the length of the circuit run from your electrical panel to where the car parks, whether the wall is finished or open, and whether your panel has room for the new 240-volt circuit. A charger mounted on the garage wall right behind the panel is a quick job; one on a detached garage across the driveway is not.
Costs for residential Level 2 equipment and installation generally land between $400 and $2,500. Most straightforward garage installs fall in the lower-to-middle of that range; the top end usually involves long runs, trenching, or a panel that needs more capacity.
The Columbia Water & Light rebate
If you're a Columbia Water & Light electric customer, the utility's residential EV-charger rebate can cover up to 50% of your project cost — up to $500 — for a Level 2 charger, including contracted labor, materials, and equipment. It's limited to one rebate per household, funded first-come, first-served, and you submit receipts within six months of installation.
Two requirements matter: the work must be done by a licensed electrical contractor, and it must be permitted. We handle both and give you the documentation you need to apply. Program terms and funding change, so confirm the current details on the official page before you buy.
Columbia Water & Light EV rebate program →Will your panel need an upgrade first?
A Level 2 charger is one of the largest continuous loads in a house. If your home still runs on 100-amp service or a nearly full panel, adding a charger can push it past its limit. Before any work, a licensed electrician runs a load calculation to confirm your panel can carry it — and flags a panel upgrade early if it makes more sense than forcing the circuit in.
That's the advantage of hiring an electrician who also does panel work: the charger, the circuit, and any service upgrade are one coordinated job, not three phone calls.
Electrical panel upgrades →Why the licensed-contractor + permit step is worth it
Beyond qualifying you for the rebate, a permitted install by a licensed electrician means the circuit is sized correctly, the connections are safe under sustained load, and the work is inspected. An EV charger runs for hours at a time, night after night — this is not the place to cut corners with a handyman or a DIY outlet.
