Generator Installation for Lebanon Homeowners
Automatic Standby Power
Whole-Home Coverage
Professionally Sized & Installed
When Lebanon homeowners need generator installation, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Lebanon in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

Lebanon Homes and What They Need
Lebanon has the newest median housing stock of the York County towns Aces studied, built in 1989, with the lowest pre-1940 share at about 14 percent. Most of that growth happened after 1980, which means a lot of Lebanon's systems are reaching the age for their first major replacement rather than a full historic rebuild.
Power, Storms and Wiring in Lebanon
Central Maine Power serves Lebanon. On a rural well-and-septic property, a standby generator is often the difference between riding out a storm comfortably and losing water along with the power.
Getting to Know Lebanon
Lebanon was incorporated on June 17, 1767, making it Maine's 23rd incorporated town, and Wikipedia describes it plainly as 'the westernmost town in Maine.' It borders Acton, Sanford, Berwick and North Berwick on the Maine side, and Milton and Rochester, New Hampshire, on the other.
The town's population grew from about 1,150 in 1930 to more than 6,400 by 2020, with most of that growth arriving after 1980. Lebanon is drained by the Little River and the Salmon Falls River, the latter forming part of the state line with New Hampshire.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Lebanon gets treated. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Getting invited back is the only metric that matters here.
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 Lebanon
Electrical work in Lebanon is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Not addressed on Lebanon's published code enforcement pages; no municipal electrical inspector is named, consistent with the State of Maine Electrical Inspection Program handling electrical permits/inspections by default. Lebanon has no confirmed public water or sewer system; plumbing work should assume private wells and septic systems townwide.
- A permanently installed combustion-engine standby generator is what the NEC calls an 'optional standby system,' covered by NEC Article 702; NFPA's own summary notes most residential units are rated under 22 kW and are frequently treated as a gas-fired appliance under the mechanical code as well. nfpa.org
- Per NFPA's summary of the (then-current) NEC, a generator installation needs disconnecting means under NEC 445.18: an emergency shutdown of the prime mover (requiring a mechanical reset), a remote emergency shutdown outside the generator enclosure for units rated over 15 kW, and — for any generator at a one- or two-family dwelling — an emergency shutdown located outside the dwelling in a readily accessible location. nfpa.org
- Where an automatic transfer switch contains the main overcurrent protective device, it typically serves as the service disconnect, and (per the 2020 NEC as described by NFPA) may also serve as the emergency disconnect required by NEC 230.85 — in which case it must be marked 'EMERGENCY DISCONNECT, SERVICE DISCONNECT' on its exterior. A load calculation or a load-management ('load-shedding') provision is expected at the transfer switch. nfpa.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 Lebanon
- 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.
- 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.

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 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!

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.

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.
