As a severe heat wave grips the Southeastern United States, federal and state officials have activated emergency measures to safeguard electricity supply and protect vulnerable residents. The U.S. Department of Energy (DOE) and the Georgia Public Service Commission (PSC) have each announced actions aimed at addressing the growing strain on the region's power systems.

On June 24, U.S. Secretary of Energy Chris Wright issued an emergency order under Section 202(c) of the Federal Power Act. The order authorizes Duke Energy Carolinas to operate certain electric generating units at full capacity to meet peak electricity demand caused by ongoing extreme temperatures. The directive, in effect through June 25, is intended to preserve the reliability of the bulk electric power system and avoid potential blackouts. The order was issued by DOE’s Office of Cybersecurity, Energy Security, and Emergency Response (CESER), pursuant to a national energy emergency declaration.

“As electricity demand reaches its peak, Americans should not be forced to wonder if their power grid can support their homes and businesses,” said Secretary Wright. “This order ensures Duke Energy Carolinas can supply its customers with consistent and reliable power throughout peak summer demand.”

Simultaneously, the Georgia Public Service Commission reminded residents of existing consumer protections in place during heat emergencies. Under PSC Rule 515-3-2-.04 (02), Georgia Power is prohibited from disconnecting electric service to residential customers for non-payment if a National Weather Service (NWS) heat advisory or excessive heat warning is in effect, or forecasted, for the area. This rule applies only to Georgia Power, the state's regulated utility; customers of electric membership corporations (EMCs) and municipal systems are advised to check with their individual providers for similar protections.

The PSC emphasized that the restriction is temporary and disconnections may resume once heat advisories are lifted.
