Generator Installation for Standish Homeowners

Standish sits in Cumberland County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for generator installation gets a technician who already knows the local housing and codes, not a first-timer.
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.

Standish Homes and What They Need
Standish, on the southeastern shore of Sebago Lake, is largely rural, and its housing shows it. Census estimates put the median home at 1980, with about half of homes built before 1980 and about 17 percent before 1940, much of the oldest in the villages of Standish Corner, Steep Falls, Sebago Lake Village and Richville. About 7 percent of homes are mobile or manufactured homes, a far higher share than in the towns closer to Portland. Most striking, nearly one in five housing units is held for seasonal or occasional use, largely camps and cottages along the Sebago Lake shore, Standish Neck and Watchic Lake. That mix means a lot of work on homes that were not built for year-round comfort: shallow or exposed plumbing, crawlspaces with no heat, electric baseboard added later, and manufactured homes whose furnaces and ductwork follow their own replacement rules.
Power, Storms and Wiring in Standish
Central Maine Power serves Standish over long rural lines through heavy tree cover, which makes the town vulnerable when ice or wind brings trees down, as it did across Cumberland County in the January 1998 ice storm and in the December 2023 storm, which left more than 56,000 county customers without power at its peak. Because most homes are on wells, losing power also means losing water, and seasonal properties left empty can freeze before anyone notices. Standish is also a long-commute town: census estimates show about 61 percent of commuters travel 30 minutes or more each way, a daily mileage where electric vehicles save the most on fuel. Adding a generator inlet, heat pumps and an EV charger to an older service usually starts with upgrading the electrical panel.

Getting to Know Standish
Standish began as Pearsontown, a township granted in 1750 to veterans of the French and Indian Wars, and was incorporated in 1785 under a new name honoring Captain Myles Standish of Plymouth Colony fame. When rail service reached Sebago Lake Station in 1870, Standish became a gateway for the lake tourism that still defines the area.
Between year-round homes and lakeside camps, Standish properties see big seasonal swings in use — which is why efficient mini-splits that can heat, cool, and be zoned room-by-room are such a natural fit here.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Standish under its own name. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. We show up, fix the actual problem, and let the work speak for itself.
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

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 Standish
Electrical work in Standish is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. No Local Electrical Inspector is named on the town's code enforcement listing; electrical work is understood to default to the State Electrical Inspector under Maine's Office of Professional and Occupational Regulation (OPOR) / Electricians' Examining Board. The historic Cumberland and Oxford Canal (opened 1832) once carried trade from Sebago Lake to Portland through this area, and the Portland and Ogdensburg Railroad reached Sebago Lake Station in 1870.
- Maine's Chapter 120 amends NEC 702.4(A)(2)(a): the 'automatic load connection / full load' capacity requirement for an optional standby system applies to systems 'other than single-family dwellings' — i.e., Maine's amendment specifically carves single-family homes out of that particular automatic-load-connection rule. maine.gov
- NFPA's field-inspection account also flags gas-side coordination as good practice: asking whether the customer's existing gas meter/regulator is sized for the added BTU load of a new generator, since meters and regulators are sized for the appliances present at the time of installation. nfpa.org
- A propane- or natural-gas-fueled standby generator's fuel hookup falls under the Maine Fuel Board's Propane and Natural Gas Technician license (the same board and license type that already covers gas furnaces and water heaters in this dataset); most residential standby generators (well under 500,000 BTU/hr) would fall under that license's Appliance Connection and Service authority. 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 Standish
- 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.
- 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.
- 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 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.

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.

This team was called in by my property management company for where I rent. Elijah and his team were professional, clear speaking. Good communicators gave me the real deal. Didn't give any runaround. I trust them and want to use them for my own projects.
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.
