Generator Installation for Kennebunk Homeowners
Automatic Standby Power
Whole-Home Coverage
Professionally Sized & Installed
Kennebunk homeowners call Aces Highlands for generator installation because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on York County roads every day — we know this area's housing, weather and permit process cold.
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.

Kennebunk Homes and What They Need
Kennebunk has the newest median home of the five York County coastal towns Aces studied, built in 1983, with under 19 percent of units predating 1940 and about 30 percent predating 1960. That newer stock still runs plenty of aging original heating and electrical systems worth a checkup.
Power, Storms and Wiring in Kennebunk
Electric service in Kennebunk is genuinely split: the Kennebunk Light & Power District, a municipal utility running since 1893, serves parts of town along with pieces of Wells, Arundel and Lyman, while Central Maine Power covers the rest. Before scheduling a panel upgrade or service change, we confirm which of the two utilities actually serves your address.
Getting to Know Kennebunk
Kennebunk broke off from Wells and Arundel to incorporate as its own town on June 24, 1820; the name comes from an Abenaki word describing 'the long cut bank.' Its Summer Street Historic District, home to the Federal-style Wedding Cake House, was the very first historic district in Maine listed on the National Register of Historic Places.
Kennebunk is also the hometown of U.S. Senator and Secretary of State Edmund Muskie and headquarters to Tom's of Maine. Since December 1893, part of town has been served by the Kennebunk Light & Power District, one of only two municipally owned Light & Power Districts left in the state.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Kennebunk gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. 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 Kennebunk
Electrical work in Kennebunk is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Kennebunk processes electrical permits locally through its Code Enforcement Office (Code Enforcement Officer Frank Kunkel and Assistant CEO Dylan Muldowney), though the town's public staff directory does not list a separately named 'Electrical Inspector' position — it's unclear from public sources whether inspections are performed by the CEO/Assistant CEO or a contracted inspector. Maine's Mandatory Shoreland Zoning Act applies along the Kennebunk and Mousam Rivers and Kennebunk's Atlantic coastline (Kennebunk Beach, Gooch's Beach, Mother's Beach), restricting structure placement near the water.
- 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 Kennebunk
- We wire standby generators to NEC Article 702's optional-standby rules, which includes a readily accessible emergency shutdown located outside the dwelling, not just at the unit itself.
- Gas and propane standby generators answer to the Maine Fuel Board as well as the electrical code, so we coordinate both approvals on the same install — Unitil (Northern Utilities) covers part of Kennebunk for anyone going the natural-gas route.
- Clearances from windows, doors and fresh-air intakes follow the manufacturer's own installation instructions, which we confirm on-site before the pad goes in.

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.

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!

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!
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.
