Energy Secretary Chris Wright issued an emergency grid stabilization order for the electrical systems serving North and South Carolina on Sept. 3, acting to prevent blackouts as a dangerous heat event threatened to overwhelm the grid ahead of the Labor Day holiday weekend.
Emergency orders from the secretary of energy are rare and carry direct public safety implications. The order was directed at preventing cascading grid failures during a period of peak residential and industrial electricity demand driven by extreme temperatures across the Carolinas.
The Carolinas electrical grid serves millions of households and a rapidly growing population base, with major utility providers including Duke Energy and Dominion Energy operating generation and transmission infrastructure across both states.
Wright’s order underscores persistent grid reliability concerns that have intensified during peak summer demand periods. Grid operators across the Southeast have warned in recent years that the combination of population growth, rising cooling demand and the retirement of baseload generation capacity has narrowed reliability margins.
The timing of the emergency order — issued before a three-day holiday weekend when staffing levels are reduced and residential cooling demand spikes — reflects the acute nature of the threat. Power outages during extreme heat events pose life-threatening risks, particularly for elderly residents, people with disabilities and those without access to cooling shelters.
Emergency grid orders authorize the secretary to direct utilities to take extraordinary steps to maintain system stability, including running generators beyond normal operating limits and importing power from neighboring grid regions.
The Department of Energy did not specify how long the emergency order would remain in effect or whether additional orders for other regions were under consideration.
North and South Carolina emergency management offices were expected to coordinate public messaging about conservation measures and cooling shelter availability through the holiday weekend.
