Need generator installation in Lewiston? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Androscoggin 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.

  • Licensed, insured, and background-checked; Google reviewers back up the work

Lewiston Homes and What They Need

Lewiston's median home was built in 1957, with about 32 percent of the housing stock dating before 1940 and 54 percent before 1960 -- a mill-city profile concentrated in the tenement and triple-decker neighborhoods that grew up around the Bates Mill complex in the late 1800s and early 1900s. That density and age combination means plumbing work in older Lewiston buildings often has to account for shared walls and stacked units, not just a single-family layout.

Power, Storms and Wiring in Lewiston

Central Maine Power delivers electricity in Lewiston, and the city's own Public Works Electrical Services Division separately maintains municipal infrastructure like street lighting and pump stations, a distinct city crew, not part of CMP's residential grid. With roughly half the housing stock predating 1960, older panels and knob-and-tube wiring are a routine find, especially in Lewiston's dense triple-decker blocks. Rewiring an older Lewiston building is one of our most common electrical calls.

Getting to Know Lewiston

Lewiston grew up around Lewiston Falls on the Androscoggin River, which started powering the Bates Manufacturing Company's mill complex in 1852. For roughly three decades, Bates was Maine's single largest employer, and it stayed one of Lewiston's biggest employers well into the 20th century, a scale of industry that shaped the city's dense, mill-town neighborhoods.

The Androscoggin River still forms Lewiston's western border, separating it from twin city Auburn, and the two towns share more than a river: Lewiston draws its water through the jointly run Auburn Water District. That kind of shared infrastructure is common between the two cities, a legacy of how closely their industrial histories are tied together.

Local & Independent — Not a Franchise

We are an independent, Portland-based company, not a franchise chain routing your Lewiston job to a call center. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We show up, fix the actual problem, and let the work speak for itself.

How a Standby Generator Works

  1. Standby generator — starts itself within seconds of an outage
  2. Automatic transfer switch — throws from utility to generator power
  3. Utility service — disconnected while the switch is on generator
  4. Feed to the panel — the switch, not the generator, connects to the house
  5. 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 Lewiston

Electrical work in Lewiston is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Lewiston has a Public Works "Electrical Services Division" that maintains city infrastructure (street lighting, traffic signals, and the water/wastewater pumping system it jointly operates with the Auburn Water District); it is distinct from Planning & Code Enforcement's Building Division, which handles private building permits. The city's site did not name an individual Local Electrical Inspector for private electrical permits. Lewiston sits on the east bank of the Androscoggin River at Lewiston Falls (Great Falls), the water power that drew the Bates Manufacturing Company and four other mills starting in 1852; Bates Mill was Maine's largest employer for three decades.

  • 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
  • A municipality may adopt its own program of electrical inspections and, once it does, may require its own local permit in place of the state permit (30 M.R.S. §4173, part of Title 30-A's 'Regulation and Inspection of Electrical Installations' subchapter). There is no population threshold for this, unlike the Maine Uniform Building and Energy Code's mandatory-enforcement line at 4,000 residents — running a municipal electrical inspection program is an individual town choice at any population size. mainelegislature.org

How Aces Highlands Handles Generator Installation in Lewiston

  • 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.

    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.

  • Malina Foss

    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!

  • Susan Donegan

    3 months ago

    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.

  • Nichole A

    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!

  • Tom

    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.
