Outage risk in South Carolina

South Carolina has a real, dated record of hurricanes knocking out power at scale. Hurricane Helene, in September 2024, left roughly 1.3 million South Carolina customers without power even though the storm never made direct landfall in the state, with Duke Energy customers in Greenville, Spartanburg, and Anderson counties seeing outage rates near 100 percent, comparisons widely made at the time to Hurricane Hugo, the Category 4 storm that made landfall near Sullivan's Island on September 22, 1989 and remained the state's benchmark disaster until Helene. Hurricane Florence, in 2018, left more than 32,000 South Carolina customers without power.
