Power in Georgia
Georgia's grid takes a beating from both ends of the calendar. Hurricane Helene tore up the state in September 2024 — Georgia Power called it the most destructive storm in the company's history, with more than 1.3 million customers knocked offline and thousands of poles snapped, while the state's electric cooperatives lost power to hundreds of thousands more across South Georgia. Winters bring ice storms that drop trees and lines across the north, and summer thunderstorms and the occasional tornado can dark a neighborhood any afternoon. When the power goes in Georgia the air conditioning goes with it, and August heat turns dangerous fast for infants, older residents, and anyone on medical equipment. A whole-house standby generator starts itself within seconds and keeps the AC, well pump, and refrigerator running for as long as the natural gas or propane holds out.
Generator permits & codes in Georgia
- Who issues permits
- Your city or county building department — Georgia has no statewide permit office, so local governments issue permits and inspect the work while enforcing the Georgia State Minimum Standard Codes adopted by the Department of Community Affairs (DCA). The electrical work takes a state-licensed electrical contractor, licensed by the Secretary of State's Construction Industry Licensing Board as either Class I (restricted) or Class II (unrestricted).
- Typical permit cost
- Set by each local government. Savannah charges a flat $80–$175 for a stand-alone generator electrical permit depending on scope; Cobb County sets an $80 minimum for a trade (electrical) permit; the City of Atlanta prices trade permits by job valuation, at $7.00 per $1,000. A generator install typically pulls an electrical permit plus a gas sub-permit, each with its own fee.
- Code in force
- The 2023 National Electrical Code with Georgia Amendments — the 2023 NEC took effect as the state minimum on January 1, 2025, and the 2026 Georgia Amendments to it took effect January 1, 2026. One- and two-family homes also fall under Georgia's adopted residential code.
- Major utilities
- Georgia Power — the state's largest, at about 2.7 million customers across 155 of Georgia's 159 counties — plus 41 electric membership cooperatives (EMCs) and 52 municipal electric systems. The EMCs together cover roughly 73% of the state's land area and 157 of its 159 counties, so most rural and suburban Georgia homes buy power from a cooperative, not from Georgia Power.
- Worth knowing
- Georgia's two electrical-license classes gate who can wire your generator. A Class I (restricted) contractor is limited to single-phase installations up to 200 amperes at the service — enough for a standby generator and transfer switch on a typical 200A home — but a 320/400A ("200A × 2") service or any three-phase service requires a Class II (unrestricted) contractor. Upsizing your service to feed a large whole-house load can quietly push the job past Class I scope.
Common questions about whole house generators in Georgia
How much does a standby generator cost installed in Georgia?
For a typical Georgia home, expect roughly $9,000–$15,000 all-in for a
whole-house air-cooled standby generator (about 18–26 kW): the unit
itself, the automatic transfer switch, a concrete or composite pad, gas
or propane piping, electrical work, and permits. Partial-home units
(10–14 kW) covering essentials can land in the $6,000–$9,000 range.
Liquid-cooled units for large homes run well past $20,000. Fuel type
matters: natural gas is cheapest to run where an Atlanta Gas Light line
reaches, but much of rural Georgia has no gas main and runs on propane,
which requires a tank.
Do I need a permit to install a generator in Georgia?
Yes. Georgia has no statewide permit office — your city or county
building department issues the electrical (and usually a gas/mechanical)
permit and inspects the work, enforcing the Georgia State Minimum
Standard Codes the Department of Community Affairs adopts. The electrical
work must be done by a state-licensed electrical contractor: Georgia
issues Class I (restricted) and Class II (unrestricted) electrical
contractor licenses through the Secretary of State's Construction
Industry Licensing Board. A reputable installer pulls the permits as part
of the job — treat one who suggests skipping them as a red flag.
What size generator do I need in Georgia?
The honest answer is a load calculation, which any good installer
performs during the site visit. Georgia sizing is usually driven by air
conditioning: essentials only (one AC zone, well pump, fridge, some
lights) fits in 10–14 kW; a typical whole house with central AC runs
18–26 kW; large homes with multiple AC units, a pool pump, or a well
need more. Because a Georgia outage almost always happens when it's hot,
undersizing means the generator sheds the load you most wanted covered —
the air conditioning. Oversizing just wastes money up front.
Generac, Kohler, Cummins, or Briggs & Stratton — does the brand matter?
All four build reliable home standby units; what matters more is the
installer and the service relationship afterward. Generac has by far the
largest Georgia dealer network, which means parts and warranty techs are
easy to find; Kohler and Cummins have strong dealers across metro Atlanta
and the larger cities. A factory-authorized dealer can handle warranty
work on its brand — worth weighing when brands otherwise look similar.

you.
How long does installation take?
The on-site work is usually one to two days once the unit is in hand:
set the pad and unit, run gas and electrical, mount the transfer switch,
and commission. The calendar time is longer — site visit, quote, permits,
and (in the rush after a hurricane or a big ice storm) unit availability
can stretch the process to several weeks. Ordering ahead of hurricane
season beats competing for a generator the week after a storm, when every
house on the block wants the same thing.
What maintenance does a standby generator need?
Annual service — oil and filter, spark plugs on schedule, battery
check, and a load test — plus the weekly self-test the unit runs on its
own. Georgia heat and humidity are hard on the cooling system and
battery, and you want the unit proven before hurricane season, not during
it. Many Georgia installers listed here offer maintenance plans, and
several service brands they don't sell. Neglected maintenance is the most
common reason a generator fails to start when the grid goes down.
