About the Carolinas grid region
The Carolinas region is anchored by Duke Energy’s balancing authorities across North and South Carolina. Hurricane season and winter cold snaps are its stress tests, and it is one of the fastest-growing load regions in the country.
On the map, this region is part of the Eastern Interconnection. Its status color comes from the ratio of actual demand to the bias-corrected day-ahead forecast: green means headroom, amber and orange mean it is tightening, and red means demand has met or passed what the operator expected, or a real emergency has been declared.

Grid regions follow balancing authorities, not state lines; split states are listed under the region that serves most of their load.
