Coastal storms, cold snaps and ice storms all threaten Maine's power supply, so a backup system here should handle multi-day outages in freezing weather. This page lists installers by city and shows how to confirm a license with the Maine Electricians' Examining Board before you hire.

Home Backup in Maine: What to Know
Outages and the Maine Grid
FEMA's National Risk Index puts expected annual losses in Maine from hurricanes at about $79 million, more than any other weather hazard that commonly knocks out power. Cold waves and ice storms come next, and Cumberland County has the highest hurricane losses in the state.
Utilities
Central Maine Power serves southern and central Maine, and Versant Power serves northern and eastern Maine.
Incentives and Utility Programs
Efficiency Maine's Small Battery Program, launched January 31, 2026, pays participating battery companies for power your battery supplies during peak demand events, and they share the payment with you. You enroll through a participating battery manufacturer or program partner, and solar isn't required.
Checking an Installer's License
Maine licenses electricians through the Electricians' Examining Board in the Office of Professional and Occupational Regulation. Verify a master or journeyman electrician's license on the board's online search.
Permits and Inspections
Electrical permit and inspection requirements depend on your town, so ask your installer what applies where you live.
Questions to Ask Before You Hire a Home Backup Installer
- Are you licensed for this work in Maine? Ask for the license number and check it with the Maine Electricians' Examining Board.
- Will you pull the permits and schedule the inspections? Permitted work protects your insurance and resale value.
- Have you installed this type of system before? Ask about battery, generator or transfer-switch projects like yours, and which brands.
- Will you install equipment I buy myself? Many installers will. Some only install what they sell. Ask before you buy.
- What's included in the quote? Look for the equipment, panel work, transfer switch, permits, utility paperwork and haul-away.
- What warranty do you provide on your workmanship? It's separate from the manufacturer's equipment warranty.
- How will the system switch over in an outage? Automatic or manual, and which circuits will be backed up.
- Who services the system after installation?

Maine Home Backup FAQs
Do I need a licensed contractor to install a home battery in Maine?
Are there Maine incentives for home batteries?
How do home batteries handle cold weather?
Lithium batteries charge more slowly in freezing temperatures, and many models protect themselves by limiting charging. Indoor or garage placement, or models with built-in heating, help. Your installer will advise on placement.
Can I buy my own equipment and hire a local installer?
Often, yes. Many installers will install customer-supplied equipment, but policies vary. Each listing in this directory shows whether the installer says they do. Confirm with the installer before you buy, and share the exact model so they can plan the installation.
Does Outbound Power install equipment?
No. Outbound Power sells home backup equipment and helps you plan a system. Installation is done by independent, licensed contractors like those listed here.
