Incoming power and capacity planning
A Service Upgrade Extends Beyond the Electrical Panel
The electrical service is the path from the utility connection through metering and service equipment to the main distribution point. Increasing capacity can involve the meter location, overhead or underground conductors, mast or raceway, main disconnect, grounding and bonding, panel equipment, clearances, utility requirements, permits, and inspection.
We begin with what is driving the project: an EV charger, heat pump, electric water heater, range, hot tub, workshop, addition, accessory dwelling unit, solar or battery planning, repeated capacity constraints, or replacement of aging service equipment.
What the Service-Upgrade Estimate Reviews
A larger amp number is not the complete scope. The existing building, utility connection, and future load plan must be considered together.
Loads and Distribution
Current and planned equipment is used to understand capacity. Existing panel spaces, feeders, subpanels, major appliances, HVAC loads, and demand-management options can influence the recommendation.
- current service and main-equipment ratings
- existing and proposed major electrical loads
- panel, feeder, and subpanel arrangement
- future circuits and practical expansion needs
Utility, Permit, and Site Conditions
The utility connection and jurisdiction can create sequencing dependencies. Meter placement, service route, clearances, trenching or mast work, inspection, and outage timing are identified before installation is scheduled.
- overhead or underground service arrangement
- meter and disconnect location
- utility coordination and project dependencies
- permit, inspection, access, and restoration boundary
How a Service Upgrade Is Planned
- The estimator documents existing service equipment, panel and feeder relationships, major loads, future equipment, meter location, utility, and site access.
- The proposed scope defines service rating, equipment, routing, grounding or bonding work, panel changes, utility coordination, permits, inspection, outage, and any finish restoration excluded from electrical work.
- Dependencies are scheduled in the correct order before power is disconnected. Timing can change with utility availability, inspection, materials, and concealed site conditions.
- After approved work, the service and distribution equipment are tested and labeled within scope, with required inspection and remaining project items documented.
Service Equipment Is Not a Homeowner Work Area
Utility and service conductors can remain energized even when branch breakers are off. Do not open meters, service compartments, or panel covers. Keep away from fallen lines, damaged masts, wet service equipment, smoke, or active arcing, and contact emergency services or the utility as appropriate.
Permits and Inspection Depend on the Exact Scope
Oregon requires permits for permanent wiring and service-equipment changes, and Portland identifies service changes and panel work as inspected projects. The utility, authority having jurisdiction, permit, and inspection sequence are confirmed for the exact address.
Review Oregon residential permit guidance or confirm project-specific requirements with the local building department.

Electrical Service Upgrade FAQ
How do I know if I need a service upgrade?
The decision requires an inventory or calculation of existing and planned loads plus review of the service equipment. A full upgrade is not determined by breaker spaces or home age alone.
Is a 200-amp upgrade always necessary for an EV charger?
No. Charger power, driving needs, existing loads, panel capacity, and possible load management all matter. The installation should be designed from the actual load plan.
Will the utility need to be involved?
Many service changes require utility coordination, but the exact process depends on the service arrangement and provider. That dependency is identified during project planning.
Is the electrical service upgrade estimate free?
Yes. The estimator visit for a planned service upgrade is free and is used to define capacity, equipment, access, utility, permit, and scheduling needs.
