Generator Installation for Gray Homeowners
Automatic Standby Power
Whole-Home Coverage
Professionally Sized & Installed
For generator installation in Gray, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from Cumberland County and already familiar with the homes, climate and codes here.
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.

Gray Homes and What They Need
Gray's roughly 4,600 homes are younger than much of Cumberland County. Census estimates put the median year built at 1983, and only about one in eight predates 1940. Those older houses cluster around Gray Village and along the old roads out toward Dry Mills. The bigger story is the building wave of the 1970s through the 2000s, when capes, ranches and colonials went up on wooded lots within reach of Turnpike exit 63; about a quarter of homes date from 2000 or later. Roughly one in twenty is a manufactured home, and around 670 units are held for seasonal use, many of them camps on Little Sebago, Crystal and Forest lakes. Houses from the 1980s and 1990s are now reaching the age where original boilers, furnaces and electrical panels with no spare breaker space come due, while a lakeside camp raises questions about insulation and year-round use.
Power, Storms and Wiring in Gray
Gray is Central Maine Power territory, and much of the town is wooded house lots on long rural roads, the setting where one fallen limb can darken a whole street. The 1998 ice storm took 23 days to fully restore statewide, the October 2017 windstorm set CMP's outage record with Cumberland County among the hardest hit, and on December 18, 2023, a wind and rain storm left more than 70,000 Cumberland County customers in the dark and led Gray to close its town office early. For a home on a private well, losing power also means losing water and, with an oil burner, losing heat, which makes a standby generator on a transfer switch more than a convenience. Census commute data show nearly half of Gray workers travel 30 minutes or more each way, a daily distance that an overnight Level 2 charger covers easily.
Getting to Know Gray
Gray holds one of Maine's most unusual Civil War stories: in 1862, the body of an unknown Confederate soldier was mistakenly shipped to Gray instead of a fallen local Union lieutenant. The women of the town buried the stranger in Gray Village Cemetery and paid for his headstone — marked simply "The Stranger" — and the grave is still tended today. Gray is also home to the Maine Wildlife Park, the state's refuge for animals that cannot return to the wild.
From the village center out to Dry Mills, Gray's homes range from 1800s farmhouses to newer builds off Route 26 — and we service heating, plumbing, and electrical in all of them.
Local & Independent — Not a Franchise
Aces Highlands answers to Gray homeowners directly, not a franchise office somewhere else in the country. 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 Gray
Electrical work in Gray is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Gray's Code Enforcement Office describes its own scope as covering building, plumbing, electrical and septic inspections, so electrical permits are handled locally through that office rather than referred to the state; no separately-named electrical inspector was published on the town's site. Gray includes frontage on Little Sebago Lake, Crystal Lake and Forest Lake and is drained by Collyer Brook — all relevant to well/septic siting and shoreland zoning outside the water district's service area.
- 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
- Maine's Electricians' Examining Board has adopted the 2026 edition of the National Electrical Code (NFPA 70), effective for all electrical installations commencing on or after July 1, 2026, subject to Maine's own amendments and exclusions set out in Chapter 120 (Electrical Installation Standards). The prior standard was the 2023 NEC, effective July 1, 2024. maine.gov
How Aces Highlands Handles Generator Installation in Gray
- 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.
- With Unitil serving parts of Gray, 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.
Hancock Street near the center of Gray village, close to the town's public library.

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!

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.
