Why Georgia is different

Georgia's outage exposure runs along a corridor that many residents do not associate with direct hurricane strikes. The state sits far enough inland that storms typically weaken before arrival, but they still carry enough wind and rain to cause widespread grid damage across the southern half of the state. Georgia Power, a subsidiary of Southern Company, is the dominant utility.

When Hurricane Michael crossed into Georgia in October 2018 as a Category 3 storm, roughly 385,000 Georgia Power customers lost service. Damage included more than 3,500 spans of downed wire, approximately 1,000 broken poles, and over 200 damaged transformers. Southwest Georgia communities like Albany, Americus, and Bainbridge bore the worst of it, with restoration in the Bainbridge area not completed until October 16, six days after the storm entered the state. Across all Georgia utilities, the U.S. Department of Energy reported over 424,000 total customer outages.

For backup sizing, the inland hurricane pattern means that damage concentrates in rural and small-city areas where utility crew staging takes longer and mutual aid must travel farther. Portable stations in south Georgia should be sized for extended runtime rather than brief overnight gaps.

NRI top hazard is Tornado, but Hurricane leads FEMA declarations with 9 of 21 total โ€” tropical systems have outsized federal impact.

Frequently Asked Questions

How high is outage risk in Georgia?

Georgia has an NRI composite risk score of 73.6 (Relatively Low), with 21 federal declarations from 2014 to 2023. NRI top hazard is Tornado, but Hurricane leads FEMA declarations with 9 of 21 total โ€” tropical systems have outsized federal impact.

What backup size should I target in Georgia?

For the primary scenario on this page (Essential 12-hour backup), the estimated minimum is 6,700 Wh for a 12-hour target. Refine this in the calculator with your actual devices.

Why do modeled risk and declaration history sometimes differ?

NRI is a modeled risk index based on hazard exposure, vulnerability, and expected loss. FEMA declarations reflect federally declared incidents. They answer different questions โ€” use both signals together for planning.

What are the most common outage-planning mistakes in Georgia?

Buying for weekend convenience use, then expecting the same setup to cover emergency outages. See the common mistakes section above for more state-specific pitfalls.
