The city points residents to three providers: Georgia Power, Sawnee EMC, and Cobb EMC.
Permits
Roswell's Building Division requires permits for electrical and gas systems, filed through the city's permitting hub.
Fuel
About 70% of Roswell homes already heat with piped natural gas, the most common fuel for a standby generator here.
Storms and outages in Roswell
Roswell's outages usually start with trees. When a severe thunderstorm hit in June 2013, more than 7,000 Georgia Power customers lost power, from west of GA-9 near North Fulton Hospital and Hembree Park to the Crossville Road and Coleman Road area and Riverside Road. Trees came down on Mimosa Boulevard and downtown.
Hurricane Helene's remnants in September 2024 brought the Chattahoochee to its 9-foot flood stage in Roswell, with some flooding along the river and more than 200 calls to the city, mostly for trees across roads. About half of the roughly 150 homes in Pine Valley, off Warsaw Road, were without power for about 24 hours.
A day without power is manageable for some households. For homes with a sump pump, medical equipment, a home office, or a basement prone to water, a standby generator keeps the essentials running automatically.
Three electric providers: know which is yours
Roswell is unusual in being served by three electric providers. The city's severe weather updates page points residents to Georgia Power, Sawnee EMC, and Cobb EMC. Sawnee's territory begins at the Chattahoochee near GA-400 and runs north. The name on your electric bill tells you which one serves your home.
Bookmark the right outage map before storm season: the Georgia Power outage map, the Sawnee EMC outage map, or the Cobb EMC outage map. For warnings, sign up for Alert Roswell; county-wide coordination comes from the Atlanta-Fulton Emergency Management Agency.
Generator permits in Roswell
Roswell's Building Division requires a permit to install, alter, repair, or replace any electrical, gas, mechanical, or plumbing system. A standby generator installation involves all of the electrical connection, the transfer switch, and usually a gas line, so expect electrical and gas permits filed through the city's Permitting & Licensing hub.
Homes in the roughly 640-acre Historic District, around Canton Street, Mimosa Boulevard, Bulloch Avenue, and the Mill Village, deserve extra planning for placement, since a generator is a visible exterior addition. Routine maintenance and battery replacement on an existing generator need no permit.
Trees, floodplains, and generator placement
Roswell has one of the strictest tree rules in the area. According to the city's tree FAQ, removing any tree larger than 3 inches in diameter requires a permit, and residents within 2,000 feet of the Chattahoochee must contact Planning & Zoning before removing any tree at all. If a generator site needs clearing, apply before the installation is scheduled.
Water matters too. The city's floodplain management page notes that about 10% of Roswell lies in or near a 100-year floodplain, mainly along the Chattahoochee, Big Creek, and Willeo Creek. Homes near the river also fall under the Metropolitan River Protection Act corridor rules. A generator should sit on a level pad above any area where water collects, especially near Big Creek.
Around Roswell: history, homes, and the river
Roswell's Historic District, about 640 acres around Canton Street, Mimosa Boulevard, and Bulloch Avenue, includes Bulloch Hall and Barrington Hall, both on the National Register of Historic Places. Below the old Roswell Mill, the Vickery Creek unit of the Chattahoochee River National Recreation Area protects the mill ruins, and in January 2026 the National Park Service approved new access improvements there.
Most Roswell homes came later. The median home was built in 1989, and about a third of all housing dates from the 1980s, including planned communities such as Horseshoe Bend. About 72% of homes are owner-occupied and nearly 60% are single-family detached houses, which is where most standby generators are installed. A 1980s electrical panel can usually take a transfer switch, but it should be checked first during an installation site visit.
Natural gas is the norm: about 70% of Roswell homes heat with piped gas. Georgia buys gas through certified marketers on the Atlanta Gas Light system, as the Georgia Public Service Commission explains, so a generator's gas line connects to the same service your furnace and water heater use.
Generator care through the Roswell year
- Spring: pollen and leaves collect in enclosures. Clear the air intake during scheduled maintenance.
- Summer: thunderstorms bring frequent outages. After a long run, check whether an oil change is due.
- Fall: an inspection and battery test prepare the unit for winter weather.
- Any time: a red status light or a house that stays dark means it is time for generator repair.
Common generator questions in Roswell, answered
It depends on your address. The City of Roswell directs residents to all three providers for outage reporting, and Sawnee EMC's territory begins at the Chattahoochee near GA-400. Service areas are assigned, so the provider on your electric bill is the reliable answer. Each provider has its own outage map.
Yes, for a permanently installed standby generator. Roswell's Building Division requires permits to install or alter any electrical, gas, mechanical, or plumbing system, which covers the generator connection, transfer switch, and gas line. Permits are filed through the city's Permitting & Licensing hub. Portable generators used with cords do not need permits.
Probably. Roswell requires a permit to remove any tree larger than 3 inches in diameter, and residents within 2,000 feet of the Chattahoochee must contact Planning & Zoning before removing any tree. Plan the generator location early so tree permits do not delay the installation.
Usually. About 70% of Roswell homes already heat with piped natural gas, delivered through Atlanta Gas Light's system. A standby generator can connect to that service, though a larger unit may need a bigger meter. Homes without gas service can use a propane tank instead.
Generac recommends service every 200 run-hours or two years on air-cooled home units. In Roswell, a yearly inspection before summer storm season is also worthwhile, because tree debris and pollen collect in enclosures and summer thunderstorms bring the most frequent outages.
