Why South Carolina Homeowners Need Generators
Protect your family from South Carolina's severe weather threats.
South Carolina’s coastline is directly exposed to Atlantic hurricanes, while inland areas face severe thunderstorms and occasional tornadoes. Hurricane Hugo in 1989 and Hurricane Matthew in 2016 demonstrated the state’s vulnerability to extended outages lasting a week or more. The Lowcountry region faces particular risk from storm surge and flooding that can compound power outage problems. South Carolina’s growing population and coastal development have increased the stakes for weather-related infrastructure disruptions. Homeowners who install generators before hurricane season benefit from lower prices, faster installation times, and the peace of mind that comes with being prepared.
