How much does a panel upgrade for an EV charger cost?
It depends on which job you actually need. A subpanel or a new panel at the same rating fixes a lack of breaker spaces. A service upgrade adds capacity and brings in the utility, which makes it the largest of the four. Load management often avoids both. National guides mix these jobs, so their ranges are wide.
These are national averages, not a quote, and not Ogden prices:
- Qmerit (March 18, 2026): if a home needs a service upgrade to 200 amps, a charger install can increase by $1,500 to $3,000.
- HomeAdvisor EV charger guide (updated June 20, 2026): $800 to $2,000 for panel upgrades.
- HomeAdvisor panel guide (updated June 17, 2026): panel replacement averages $1,347, with most spending $518 to $2,193. The page gives different ranges for a 100 to 200 amp upgrade in different sections, and does not separate panel work from utility work, so treat it as a rough frame.
The general variables behind a charger price are on EV charger installation cost. This page is about the panel line, which is usually the largest one when it appears.
Which of the four jobs do you need?
Match the job to the problem. No room for a breaker is a space problem, solved by a subpanel or a new panel. Too little capacity in the load calculation is a capacity problem, solved by a lower charger setting, load management or a service upgrade. Paying for a capacity fix when you have a space problem, or the reverse, is the expensive mistake.
| Option | Fixes | What you pay for | Utility involved? |
|---|---|---|---|
| Lower charger setting | Small capacity shortfall | Nothing extra; often a smaller breaker and wire | No |
| Load management | Capacity shortfall | Device or meter, current sensors, setup, permit | No service change |
| Subpanel | No breaker spaces | Subpanel, feeder, breakers | No service change |
| New panel, same rating | No spaces; worn or obsolete panel | Panel, breakers, labor, wall repair | Only if meter work is needed |
| Service upgrade | Capacity shortfall | Panel, meter socket, service conductors, utility fees | Yes |
A subpanel is common in detached rear garages behind older Ogden homes, where it serves the charger and the garage together. That cost is covered on detached garage EV charger installation cost.
What adds cost to a service upgrade?
The utility side. Rocky Mountain Power's rules have the customer provide the meter socket, pay a fee for connection and disconnection, and pass local inspection before the company reconnects. If the utility's own equipment has to be upgraded, it may require a contract first. Permit fees also rise with the project's valuation.
These come from Rocky Mountain Power's Electric Service Requirements manual and its Electric Service Regulation No. 5:
- Meter socket: "The customer must provide and install the meter socket."
- Connection fee: the customer pays "a fee for connection or disconnection according to the fee schedule in effect."
- Only the utility connects: services may not be jumpered before local inspection and permanent connection by the company.
- Utility upgrades: before adding load such as car chargers, the customer contacts the company, which "may require the applicant to enter into a line extension contract."
Rocky Mountain Power asks you to call 1-888-221-7070 when your electrician needs a utility service upgrade. We could not find a published residential timeline or fee amount, so call early and build its schedule into the plan.
Permit fees scale with the job. Ogden City's fee table in Ordinance 2024-14 charges $92.75 for the first $2,000 of valuation, plus $16.00 for each additional $1,000, on projects valued from $2,001 to $25,000. Plan review is charged separately where it applies. A service upgrade usually lands in a higher band than a simple charger circuit. Fee rules for the other cities are on the installation cost page.
What does load management cost compared with an upgrade?
You pay for a device and its installation instead of a new panel, service conductors and utility work. The 2023 NEC (220.70) lets the load calculation count the system's setpoint instead of the charger's full rating. The trade-off is that charging slows or pauses when the house is busy.
Device types range from a charger paired with its own energy meter, to a standalone controller, to a smart panel that replaces your main panel. A smart panel is a panel replacement and is priced like one. We have not listed device prices because we could not confirm current figures. Ask for the device and its installation as separate lines. The options are compared on EV charger load management.
An upgrade can still be the better buy if you plan a heat pump or a second EV, or the panel needs replacing anyway. A second Level 2 charger at 48 amps counts as another 11,520 watts in the calculation.
How do you check an upgrade quote?
Ask what problem it solves and how that was measured. A sound upgrade quote shows the load calculation, the charger setting it assumed, and whether a lower setting or load management was considered. It also says whether the job is a panel or a service upgrade, and who coordinates with Rocky Mountain Power.
- Is there a load calculation, with the charger at 7,200 W or nameplate, whichever is larger?
- What charger amperage setting did the calculation assume?
- Were a lower setting and load management priced as alternatives?
- Panel replacement, subpanel or service upgrade: which, and to what rating?
- Meter socket, service conductors and utility fees: included or extra?
- Permit, inspection and wall repair: included?
- Who contacts Rocky Mountain Power and schedules the disconnect?
We run the load calculation and price load management before we recommend a panel or service upgrade, and list the panel work as its own line. What the job involves is explained on EV charger panel upgrades.
Panel upgrade cost questions
Is a panel upgrade the same as a service upgrade?
No, and the price difference is large. A panel upgrade replaces the breaker panel. A service upgrade raises the amperage the utility delivers, which adds the meter socket, service conductors and Rocky Mountain Power's connection work. A new panel at the same rating adds spaces, not capacity.
Does Rocky Mountain Power charge for a service upgrade?
Its Electric Service Requirements manual says the customer pays a connection or disconnection fee from the fee schedule in effect, and provides the meter socket. If the utility's own equipment needs upgrading, it may require a contract first. Call 1-888-221-7070 early to learn what applies to your home.
Is load management cheaper than a panel upgrade?
It usually avoids the largest items: a new panel, service conductors and utility work. You still pay for the device and its installation, and charging slows when the house is busy. Get both priced on the same quote, based on the same load calculation.
How do I know an upgrade is really needed?
Ask for the load calculation. Under the 2023 NEC a charger counts at 7,200 watts or its nameplate, whichever is larger, and the total is compared with your service rating. A quote that recommends an upgrade because the panel looks full or old, without a calculation, has not shown the need.
