Safe, code-compliant panel and service upgrades for Cape Elizabeth homes and businesses — from 100-amp to 200-amp service and beyond.
Fuel oil heats close to 64 percent of occupied Cape Elizabeth homes in the latest five-year Census estimates (ACS 2020-2024). That is a larger share than in Portland, South Portland, Westbrook or Scarborough, and it makes the town one of the places where the switch to heat pumps will change household electrical loads the most. Only about 12 percent of homes heat with electricity today, about 11 percent with propane and about 10 percent with utility gas. Every oil boiler that gives way to cold-climate heat pumps moves the whole heating season onto the electric service. Heat pumps sized to carry a house through January draw steadily for months, not just on the coldest nights, which is why they show up on a load calculation in a way an oil burner never did.
The housing makes that a panel question in most cases. About 90 percent of homes are detached single-family houses and about 88 percent are owner-occupied, the median home was built in 1967, and only about 7 percent went up in 2000 or later. So most houses in town carry a service that was sized decades ago, before anyone planned for heat pumps, an electric car, an induction range and a heat pump water heater under one roof. Fuse boxes, 100-amp panels with no open slots, and breakers stacked with tandems are all signs that a load calculation is due before the next major appliance arrives. Owners planning solar panels should add them to the same calculation, since the panel’s bus rating limits how much a system can feed back.
The Town of Cape Elizabeth’s Code Enforcement office processes the permits for electrical work along with building, plumbing and heating permits, so a service change is permitted and inspected locally. Central Maine Power pulls the meter and reconnects it once the new equipment is in place, and Goodnow Electric schedules that disconnect as part of the job. Near the shore, salt air takes a toll on outdoor meter sockets, masts and disconnects, and an upgrade is the natural time to replace rusted enclosures and fittings. The company also replaces Federal Pacific, Zinsco and Challenger panels and adds whole-home surge protection while the service is open.

“We had a major issue happen near Easter, we called multiple people, this company was right on ball calling us back. He is amazing, instead of making us feel insecure he assured us that we was in right direction, took time out of his own day to answer us after hours and even called back for a follow…”
