An electrical panel upgrade increases the amperage your home can draw, typically moving a 60 or 100 amp service up to 200 amps. It replaces the panel, main breaker, service entrance conductors and usually the meter base and service mast so every part of the path is rated for the new capacity. Electrician Portland Oregon is a licensed, owner operated electrical contractor serving Portland, Oregon since 2011. Diagnosis is a load calculation, not a glance at the panel: we add up your existing circuits and the loads you plan to add under the Oregon Electrical Specialty Code method, and the math tells us whether you need 200 amps or whether load management gets you there without a service change.
Portland is in the middle of a capacity crunch. Homes on the inner east side and north side built between 1900 and 1940 still run on 60 to 100 amp services that were fine for lights and a range. Since the 2021 heat dome, heat pumps and mini splits are going into houses that never had cooling. Level 2 EV chargers want 40 to 60 amps by themselves. Gas to electric conversions move heating and cooking onto the panel, and ADU projects need a feeder and subpanel fed from a service with room to spare. Any one of these can fit on a healthy 100 amp service; two or three of them usually cannot, and that is when the upgrade becomes the first line item of the larger project.
A panel upgrade in Portland requires an electrical permit from Portland Permitting and Development and coordination with your utility, PGE for most of the city or Pacific Power in parts of west and southwest Portland, because the service drop must be disconnected and reconnected. The work must meet the Oregon Electrical Specialty Code: a grounding electrode system with ground rods and a grounding electrode conductor sized for the new service, bonding of water and gas piping, 36 inches of working clearance in front of the panel, and an inspection before the utility reconnects. Portland panels usually live in basements and garages, so routing new service entrance conductors from the meter to an interior panel, and finding legal clearance in a basement full of shelving, is often the hardest part of the design.
The edge cases are where experience pays. Older services on the east side sometimes share a mast or have a service drop crossing a neighbor's property, and the utility may require a new attachment point, which changes the scope. A 200 amp panel does not fix undersized service entrance conductors, so we verify the whole path, because we regularly find 100 amp wire feeding a panel someone already swapped. Wet season corrosion in the meter base can make the cutover longer than planned. And we anchor and brace equipment with Cascadia in mind, because a panel that tears its connections loose in an earthquake becomes an ignition source. If your existing panel is failing rather than undersized, a Federal Pacific, Zinsco or fuse box at adequate capacity, you want our electrical panel replacement service instead.
Technician insight
A new 200 amp panel does not fix undersized service entrance conductors, and in Portland we regularly open jobs to find 100 amp wire feeding a panel someone already swapped. The other scope changer here is the utility side: older east side services sometimes share a mast or cross a neighbor's property, and a required new attachment point rewrites the plan.
200 Amp Upgrade Ahead of a Heat Pump in Woodstock
A couple in Woodstock booked a heat pump install after 2 summers without cooling, and their HVAC contractor flagged the 100 amp service before committing to equipment. Our load calculation confirmed the panel could not carry the heat pump plus the Level 2 charger they wanted the following year, so we scoped a full 100 to 200 amp upgrade. We filed the permit with Portland Permitting and Development and booked the disconnect with PGE, which set the project date about 3 weeks out. On cutover day the meter base came off the wall with wet season corrosion behind it, so the mast and weatherhead were replaced along with the new service entrance conductors, panel and grounding electrode system. The city inspected in the afternoon, PGE reconnected before dinner, and every circuit was transferred and typed into a new directory. The heat pump went in the following week on a service with room to spare.

How it works
- 1
Load Calculation And Site Review
We calculate your existing and planned loads, inspect the mast, meter base and panel location, and confirm whether 200 amps, a larger service, or load management is the right answer.
- 2
Permit And Utility Scheduling
We file the permit with Portland Permitting and Development and book the disconnect and reconnect with PGE or Pacific Power, which sets the project date.
- 3
Cutover Day
Power is down for most of one day while we set the new panel, service entrance conductors, meter base and grounding system, then transfer and label every circuit.
- 4
Inspection And Reconnect
The city inspects, the utility reconnects, and we verify voltage, test AFCI and GFCI breakers and walk you through the new panel directory.
Pricing
Most 100 to 200 amp panel upgrades in Portland land between $3,500 and $7,500, with 60 amp services and complicated routings running higher. The price movers are the condition of the mast and meter base, how far the panel sits from the meter, whether the service is overhead or underground, whether the utility requires a new attachment point or transformer work, how many circuits must be transferred and relabeled, and whether rot or corrosion is found once the old equipment comes off the wall. Permit and utility fees are separate. You get a firm written price after the site visit and load calculation, not a phone estimate.
