Electrical Panel Upgrades in Portland, ME
Safe, code-compliant panel and service upgrades for Portland homes and businesses — from 100-amp to 200-amp service and beyond.
Electrical Panel Upgrades for Portland Homes & Businesses
If your Portland home still runs on a 100-amp panel, an old fuse box, or a recalled brand like Federal Pacific or Zinsco, Goodnow Electric can upgrade it to a modern 200-amp service that safely powers today's appliances, EV chargers, heat pumps, and additions. We serve homeowners and businesses across Cumberland County with clean, permitted panel work and an owner on-site for every job.
Portland's peninsula housing — triple-deckers on Munjoy Hill and the West End, many still on 60- or 100-amp fuse services fed through cramped basements — is exactly where undersized panels show up. We've swapped out recalled Federal Pacific and Zinsco boxes in Deering capes and coordinated CMP disconnects on tight Old Port lots where one meter stack feeds several units. Portland permitting runs through the city's Inspections Division, and we handle that paperwork so your upgrade passes on the first visit.
Across the West End, Munjoy Hill, and East Bayside and the rest of Portland, we regularly replace undersized and aging panels that can no longer keep up with modern electrical loads. We pull the permit, coordinate the utility disconnect with CMP, and get your power back on the same day in most cases.

Electrical Panel Upgrades in Portland — FAQs
How much does a panel upgrade cost in Portland, Maine?
Most 200-amp panel upgrades in Portland run roughly $2,000 to $4,000 depending on the condition of your service entrance, meter, and grounding. We give every Portland customer a free written estimate before any work begins.
Do I need a permit to upgrade my electrical panel in Portland?
Yes. Panel and service upgrades in Portland require an electrical permit and a final inspection. Goodnow Electric handles the permit and coordinates the inspection for you as part of the job.
How long does a panel upgrade take?
Most Portland panel upgrades are completed in a single day. Your power is off for only a few hours while we make the swap and coordinate the utility reconnect.
Local & Independent — Not a Franchise
Goodnow Electric is a locally owned, owner-operated shop based at 51 Wilson Dr, Westbrook, ME 04092 — not a franchise or a call-center dispatcher. When you book electrical panel upgrade in Portland, you get a Maine Master Electrician on the job, not a rotating crew of subcontractors. Our work is performed under Maine Master Electrician license MS60021971, and we're fully licensed, bonded, and insured for every job we take in Cumberland County.
That means the person who quotes your Portland project is the same person accountable for the finished work — permits pulled, code followed, and the site left clean.
Getting to Know Portland
Portland has burned to the ground four times, most famously in the Great Fire of 1866, which leveled some 1,800 buildings and left ten thousand residents homeless. The city rebuilt in brick — which is why the Old Port's Victorian commercial blocks look the way they do — and adopted the motto "Resurgam," Latin for "I shall rise again," with a phoenix on the city seal. Up on Munjoy Hill, the 1807 Portland Observatory still stands as the last surviving maritime signal tower in the United States.
All that 19th-century rebuilding means Portland carries one of the oldest housing stocks in Maine. Homes wired generations ago — some still with knob-and-tube or 60-amp fuse panels — were never designed for heat pumps, EV chargers, and modern kitchens. That's exactly the kind of careful old-house rewiring and panel work our electricians handle in Portland every week.
