Home Backup in Maryland: What to Know
Outages and the Maryland Grid
Heat waves lead Maryland's outage-related weather risks, with about $140 million in expected annual losses in FEMA's National Risk Index, followed by hurricanes and tornadoes. Within the state, Baltimore County faces the highest heat-wave losses.
Utilities
Major electric utilities in Maryland include BGE, Pepco, Delmarva Power and Potomac Edison, and the Southern Maryland Electric Cooperative (SMECO) serves much of southern Maryland.
Incentives and Utility Programs
Maryland's energy storage income tax credit ended after 2024. The Maryland Energy Administration replaced it with a Residential and Commercial Energy Storage grant program that awards limited funding first come, first served, so check MEA for the current funding round.
Checking an Installer's License
Maryland licenses master electricians statewide through the State Board of Electricians in the Maryland Department of Labor. Check a license on the board's license search.
Permits and Inspections
Electrical permits come from your county or city, such as Montgomery County's Department of Permitting Services.
Questions to Ask Before You Hire a Home Backup Installer
- Are you licensed for this work in Maryland? Ask for the license number and check it with the Maryland State Board of Electricians.
- 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?

Can a home battery run my air conditioner?
Many whole-home systems can run central AC if the battery and inverter are sized for its starting and running load. Your installer should confirm the AC unit's requirements during the site visit.
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.
