Generator Installation for Biddeford Homeowners

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

Biddeford Homes and What They Need
Biddeford's housing stock runs old: the median home was built in 1952, with about 41 percent of units predating 1940, reflecting the mill-era rowhouses and multi-family buildings that went up through the early 20th century. That density and age combination means rewiring a Biddeford multi-family often involves tracing circuits that were added or changed unit by unit over the decades.
Power, Storms and Wiring in Biddeford
Central Maine Power, Maine's largest electric utility, serves Biddeford. With so much of the city's housing built before 1940, older panels and knob-and-tube wiring show up regularly on service calls, especially in the mill-era multi-family buildings. Panel upgrades are a routine first step before adding central air or an EV charger.

Getting to Know Biddeford
Biddeford's roots go back to the winter of 1616-17, when European settlers first arrived at Biddeford Pool -- roughly four years before the Mayflower landed at Plymouth. Once incorporated as Saco in 1653, it reorganized under the Biddeford name in 1718 and was chartered as a city in 1855.
The Saco River drops about 40 feet over falls in Biddeford, power that once ran one of New England's largest textile mill complexes, employing as many as 12,000 people before the last mill finally closed in 2009. The city covers about 59 square miles, nearly half of it water, with roughly 15 miles of river and Atlantic frontage at Biddeford Pool and Fortunes Rocks.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Biddeford under its own name. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. Earning the next call, not hitting a sales target, is the entire business plan.
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 Biddeford
Electrical work in Biddeford is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Biddeford employs its own municipal Electrical Inspector (Robert Prescott, per the city's staff directory) within the Code Enforcement Office, who issues and inspects electrical permits for the city. Maine's Mandatory Shoreland Zoning Act applies within 250 feet of the Saco River and Biddeford's Atlantic coastline (Biddeford Pool, Fortunes Rocks), restricting building/structure placement near the water.
- 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
- Central Maine Power (CMP), a subsidiary of Avangrid, describes itself as serving 'approximately 670,520 electricity customers in an 11,000 square-mile service area in central and southern Maine' — the region that contains the entire Augusta-to-York corridor. Consistent with this, South Portland's own permitting page requires a CMP account/work-order number on any electrical permit tied to a service change, and Buxton's electrical permit application has a dedicated field for the applicant's CMP account number. cmpco.com
How Aces Highlands Handles Generator Installation in Biddeford
- 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 Biddeford 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!

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.
