Generator Installation for Kennebunkport Homeowners
Automatic Standby Power
Whole-Home Coverage
Professionally Sized & Installed
Need generator installation in Kennebunkport? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers York County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.
Maine storms knock out power when you need it most. Aces Highlands installs whole-house standby generators that switch on automatically — keeping your heat, water, and essentials running through any outage in Greater Portland and Southern Maine.
A standby generator sits permanently outside your home and starts automatically the moment the power goes out — no cords, no manual switching, no cold nights. We install Generac and other leading standby systems sized to cover your whole home or just the circuits that matter most: heating, well pump, refrigeration, sump pump, and lighting.
Every installation includes a properly sized generator, an automatic transfer switch wired to your electrical panel, and a fuel connection to natural gas or propane. We handle permitting, placement, and inspection so your system is safe, code-compliant, and ready before the next storm.
We start with a load assessment to recommend the right capacity for your needs and budget — no overspending on a unit larger than you need. We offer financing options on whole-house generators, and we provide ongoing maintenance to keep your backup power ready year-round. Contact us for a free estimate.

Kennebunkport Homes and What They Need
Kennebunkport's median home was built in 1982, with about 13 percent of units predating 1940 and 29 percent predating 1960 -- a mix of early-1900s shingle-style cottages in the Cape Arundel Summer Colony Historic District alongside newer coastal construction. Those older cottages are prime candidates for a heat pump retrofit that extends comfortable use into the shoulder seasons.
Power, Storms and Wiring in Kennebunkport
Central Maine Power serves Kennebunkport; the municipal Kennebunk Light & Power District that covers part of neighboring Kennebunk does not extend into town. On older coastal cottages, salt exposure and undersized original panels make panel upgrades a common request before adding modern kitchen or heat pump circuits.
Getting to Know Kennebunkport
Kennebunkport was first incorporated in 1653 as Cape Porpus, renamed Arundel in 1701, and finally took its current name in 1821 to reflect a growing shipbuilding and trading economy. Walker's Point, the Bush family's summer estate here, has hosted world leaders including Margaret Thatcher and Mikhail Gorbachev.
Cape Porpoise remains a working fishing harbor village within the town, keeping its own restaurants, church, library and commercial fleet. The Cape Arundel Summer Colony Historic District, running from Chick's Creek to Walker's Point, is full of early-1900s shingle-style summer cottages that still define much of the town's coastline.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Kennebunkport gets treated. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
How a Standby Generator Works
- Standby generator — starts itself within seconds of an outage
- Automatic transfer switch — throws from utility to generator power
- Utility service — disconnected while the switch is on generator
- Feed to the panel — the switch, not the generator, connects to the house
- Weekly exercise cycle — runs itself briefly so it starts when needed
Homeowner Guide
Standby Generators: Sizing, Transfer Switches & Fault Lights
Maine loses power in a way most of the country doesn't — a January ice storm can mean days, not hours. A standby generator is one of the few electrical projects homeowners research almost as thoroughly as we do, so here's the technical part laid out plainly.

Codes & Permits for Generator Installation in Kennebunkport
Electrical work in Kennebunkport is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. The Town of Kennebunkport does not issue electrical permits itself. Per the Town's own Forms and Permits page, all electrical work must be performed by a Maine-licensed electrician under the State of Maine electrical inspection program (Office of Professional & Occupational Regulation / Electricians' Examining Board); the Town only separately permits generator installations. Coastal town including the Cape Porpoise working fishing harbor village and Goose Rocks Beach; the Town maintains a separate Flood Hazard Development Permit for shoreland/flood-zone construction.
- The electrical work on a generator (wiring, transfer equipment) is separate, licensed electrical work requiring a Maine electrician — it is not covered by the Fuel Board license, which covers only the fuel/appliance side. mainelegislature.org
- The Town of Eliot's current process treats generator installation as a building-permit item, not a separate electrical permit: 'A building permit is required for the installation of a generator... The Town will not issue a separate electrical permit for the generator,' while the electrical work itself must still be done by a Maine-licensed Master or Limited Electrician per state law. This illustrates that a corridor town's generator permit process can differ from its general electrical permit process. source
- 25 M.R.S. §2468 requires CO detectors near bedrooms based on occupancy/construction type; it does not specifically address standby generators, so it neither requires nor exempts a CO detector because a generator is present — the general occupancy-based requirement is what applies (see general facts). mainelegislature.org
- For a single-family dwelling exempted from the state permit, the Board's Single-Family Dwelling Certification page states the underlying rule: 'Any electrical installations made in a newly constructed residence shall require certification by a State or Local Inspector, Master Electrician or Limited Electrician in House Wiring prior to the activation of electricity by the utility company.' This certification step (rather than a standard state permit) is what lets an owner wire their own single-family home. maine.gov
How Aces Highlands Handles Generator Installation in Kennebunkport
- A permanent standby generator is what the NEC calls an "optional standby system" under Article 702, and it needs its own emergency-shutdown disconnect — outside the house, in a spot you can reach without going near the unit.
- A gas- or propane-fired standby unit also falls under the Maine Fuel Board's licensing rules, which is a separate sign-off from the electrical permit.
- We set clearances to windows, doors and vents exactly per the manufacturer's spec sheet for that unit — not a rule of thumb — before anything gets bolted down.

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

Highly recommend! Cannot thank them enough for fixing my water heater. Elijah is very reliable and communicative. No hassle, no phone tag, transparent with cost and quick to repair the issue. I know who to call if I need help again!

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

Generator Installation FAQs
How fast does a standby generator turn on when the power goes out?
Typically within 10 to 30 seconds of a grid failure, the automatic transfer switch starts the generator and picks up your circuits — no one has to be home and nothing has to be plugged in. When utility power returns, it transfers back and shuts down on its own.
What size generator do I need for my house?
Essentials-only coverage (heat, well pump, refrigeration, sump pump, lights) often fits a 10-14 kW unit; whole-home coverage typically runs 18-26 kW. We perform a load assessment and size to what you actually need — never a bigger unit than the math supports.
How much does a whole-house generator cost installed?
Nationally, most installed standby systems run $9,000-$15,000 depending on capacity, fuel hookup, and site conditions, with essentials-only systems costing less. We provide a firm written quote after the load assessment, and financing is available.
Propane or natural gas — which fuel is better for a generator?
If your street has natural gas, it offers unlimited runtime without deliveries. Most of Maine runs on propane, which works excellently — we size the tank so the generator can run for days. Either way, we handle the fuel connection ourselves under our Maine gas licensing.
What maintenance does a standby generator need?
An annual service — oil and filter, spark plugs as needed, battery check, and a transfer-switch test — plus the weekly self-test the unit runs automatically. We offer ongoing maintenance so your generator is ready before every storm season, not discovered dead during one.
