The U.S. Department of Energy (DOE) has issued an emergency order to help prevent blackouts in the Carolinas amid exceptionally hot weather. The order, authorized under Section 202(c) of the Federal Power Act, allows Duke Energy Carolinas, LLC and Duke Energy Progress, LLC to run designated power units at maximum output, regardless of federal, state, or local environmental permit restrictions.

This measure follows a request from Duke Energy and aims to address blackout risks caused by high electricity demand and elevated temperatures across the region. The DOE emphasized that maintaining affordable, reliable, and secure power in the Duke Energy service area is a priority.

The order took effect on July 2, 2026, and will expire at 10:00 PM Eastern Daylight Time on July 6, 2026. According to the DOE, this action is part of ongoing efforts to ensure electric power access for residents and businesses in the Carolinas during extreme weather events.
