Greenville sits in South Carolina's Upstate region, near the Blue Ridge foothills, and is served by Duke Energy Carolinas — a genuinely different utility from Dominion Energy South Carolina, which covers Columbia and Charleston further south and east. The Upstate's higher elevation and inland position mean more frequent winter ice events than South Carolina's coastal and Midlands regions typically see, on top of the state's broader severe-thunderstorm season.
