Generator Installation · Georgia
A generator must connect through a transfer switch or an approved interlock so it can never feed power back into utility lines. Electricians install standby generators, portable generator inlets with interlocks, and the transfer equipment for both.
Rapid suburban growth around Atlanta brings EV chargers and additions, while summer storms bring surge and outage calls.
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 generator installation is planned and scheduled. These local guides cover the Georgia cities where we have written specific notes.
Atlanta's mature tree canopy means storms often bring limbs down on lines and cause outages that last hours or days. Many homeowners install a portable-generator inlet with an interlock for essential circuits, or a standby generator with an automatic transfer switch.
Utility: Georgia Power (some areas: an electric membership corporation)
When Hurricane Helene's winds tore through Augusta in September 2024, they brought down trees across the city and left most homes without power, some for weeks, and the February 2014 ice storm caused long outages too. Many families now want backup for the refrigerator, fans, a window AC unit and a well pump in outlying areas.
Utility: Georgia Power
Hurricanes Matthew in 2016 and Irma in 2017 both brought outages and flooding to Savannah, and low-lying neighborhoods near the marsh face flooding from heavy rain and high tides too. Backup power here means thinking about water: standby generators should sit above expected flood levels, in enclosures suited to salt air.
Utility: Georgia Power
Ice storms and summer storms in Cobb County bring down trees on lines, and outages can last days in Marietta's wooded neighborhoods. Many homeowners want backup for the refrigerator, heat or air, and a sump pump.
Utility: Marietta Power (city-owned) or Georgia Power / Cobb EMC, depending on address

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: Atlanta: Inside city limits, electrical permits come from the City of Atlanta's Office of Buildings; surrounding cities and counties issue their own. Augusta: Electrical permits come from Augusta's planning and development department. Savannah: Inside city limits, electrical permits come from the City of Savannah's development services; Chatham County and the island communities have their own. Marietta: Electrical permits inside city limits come from the City of Marietta's development services; Cobb County handles unincorporated areas.
