Electrical Panel Upgrade · Alabama
A panel upgrade replaces your breaker panel, and often the service entrance, so the home can safely carry more load: an EV charger, heat pump, induction range or addition. It always needs a permit, and usually needs the utility to disconnect and reconnect power.
Severe thunderstorms and tornadoes in spring, plus hurricane remnants in the south, make surge protection and generator hookups common requests.
Across the Southeast, homes deal with heat, humidity, frequent thunderstorms and hurricane season near the coast. Permit offices, utilities and housing stock differ by city, which affects how electrical panel upgrade is planned and scheduled. These local guides cover the Alabama cities where we have written specific notes.
Birmingham's older neighborhoods climb the slopes of Red Mountain, and homes in Southside, Highland Park, Forest Park and Crestwood date largely from the early to mid-1900s. Many have 100 amp or smaller services that were never meant for central air, a modern kitchen, a heat pump and an EV charger together.
Utility: Alabama Power
Mobile homeowners face a mix of panel concerns: mid-century houses in Midtown and west Mobile with 100 amp panels or brands insurers question, raised historic cottages with small services, and homes where hurricanes have damaged meter bases. Adding a larger AC system, a standby generator or an EV charger usually requires more capacity.
Utility: Alabama Power
Many Montgomery homes from the 1960s and 1970s have 100 amp panels that are already full, and adding a larger AC system, an EV charger or a generator inlet usually means an upgrade. Older homes in Cloverdale and Capitol Heights may have even smaller services or outdated equipment.
Utility: Alabama Power
Mid-century homes in Five Points, Blossomwood and Jones Valley often have 100 amp panels with little room for new circuits, and historic homes in Twickenham may have even smaller services. Adding a larger AC system, an EV charger or a generator inlet usually needs an upgrade.
Utility: Huntsville Utilities (city-owned, TVA power)
1. Load calculation
The electrician sizes the service from your existing and planned loads.
2. Permit and utility coordination
The permit is pulled and the utility schedules disconnect and reconnect.
3. Install the panel and service parts
New panel, breakers, grounding and bonding, and service conductors or meter base if needed.
4. Inspection
The local inspector checks the work before or after power is restored, depending on the jurisdiction.
Electricians set their own prices; local permit fees and utility requirements add to these factors.
Permits come from the city or county where the home is. For example: Birmingham: Inside city limits, electrical permits come from the City of Birmingham's Department of Planning, Engineering and Permits; Homewood, Mountain Brook, Hoover and other suburbs issue their own. Mobile: Inside city limits, electrical permits come from the City of Mobile's central permitting office; unincorporated Mobile County has its own process. Montgomery: Electrical permits inside city limits come from the City of Montgomery's inspections department; areas outside the city follow county rules. Huntsville: Electrical permits in Huntsville come from the city's Inspection Division; Madison and unincorporated Madison County have their own.

If you have 100 amps or less and are adding an EV charger, heat pump or electric range, or your panel is a Federal Pacific, Zinsco or fuse box, ask an electrician for a load calculation.
Usually most of one working day, depending on the scope and how quickly the utility reconnects.
