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 is Maine's largest city, and its housing stock runs from century-old peninsula triple-deckers on Munjoy Hill and the West End to new construction in Deering and along the waterfront. Goodnow Electric handles electrical panel upgrade for Portland homeowners and businesses every week, and we know how the city's older wiring, tight lots, and permitting through the Inspections Division all factor into a clean, code-compliant job.
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.

“After needing an emergency fix late on a cold winter's Sunday, Goodnow came to the rescue! With no power and dark approaching we called around and couldn't find any place that could help. When we gave Goodnow a call, Bret had one of his guys come over and help us out. David came over, checked things out, replaced some parts in our electrical box and we had light (and heat!!!) back again! So kind, helpful and a real life saver during emergencies!”
