News Summary
Duke Energy Corp. has filed a request to merge its subsidiaries Duke Energy Carolinas and Duke Energy Progress, promising over $1 billion in savings for customers. The merger aims to streamline operations and simplify rate structures as it seeks regulatory approval. With a combined capacity of 34,600 megawatts, this move is expected to enhance reliability and reduce costs. The proposal includes a plan to share benefits with South Carolina customers temporarily while improving resource planning and grid reliability in the Carolinas.
North Carolina – Duke Energy Corp. has submitted a request for regulatory approval to merge its electric utility subsidiaries, Duke Energy Carolinas (DEC) and Duke Energy Progress (DEP). The merger aims to provide substantial financial savings to customers, projecting over $1 billion in savings within the next decade and reaching up to $3.2 billion by 2038.
The formal merger request was filed on August 16, 2025, with plans for the merger to take effect on January 1, 2027, pending approvals from federal and state regulators. Duke Energy is the largest electric utility in North Carolina, serving approximately 4.7 million residential, commercial, and industrial customers across both subsidiaries.
DEC currently provides 20,800 megawatts of energy capacity, serving 2.9 million customers in North and South Carolina. Meanwhile, DEP offers 13,800 megawatts of energy capacity and serves 1.8 million customers in the same areas. If the merger is approved, the combined entity will cover a vast service area of 52,000 square miles and own a total energy capacity of 34,600 megawatts.
The merger is designed to streamline operations, allowing the utilities to share infrastructure costs, which can lead to lower rates for consumers. Currently, the existence of two separate subsidiaries has resulted in four different retail rate structures, causing confusion among customers. With the merger, these rates are expected to blend gradually, providing a simpler rate structure.
In addition to cost savings, Duke Energy anticipates that the merger will reduce the need for additional resources to meet electrical demands compared to continuing to operate as separate entities. Minimal job losses are expected, as the merger is framed as a functional integration rather than a complete corporate merger.
To move forward with the merger, regulatory clearances are required from the North Carolina Utilities Commission, the Public Service Commission of South Carolina, and the Federal Energy Regulatory Commission. To address any potential concerns from regulators regarding the impact on customers, Duke Energy has proposed a “Share the Benefits” plan. This plan would allocate a portion of the savings generated for North Carolina retail customers to benefit those in South Carolina temporarily.
The estimated cost of executing the merger is $143 million, with expectations that the subsequent savings will significantly surpass these costs. Duke Energy emphasizes that by merging the operations, the company can better plan resources and enhance grid reliability while minimizing redundant investments.
The planned merger represents a significant step toward modernizing Duke Energy’s infrastructure to meet the growing energy demands in the Carolinas. As energy needs continue to evolve, this merger is part of Duke Energy’s strategic approach to balancing distributed generation resources and improving operational efficiency within the electric utility sector.
In conclusion, the proposed merger between Duke Energy Carolinas and Duke Energy Progress is positioned to deliver substantial financial benefits for customers while enhancing service delivery and reliability. As the regulatory review process unfolds, stakeholders will be watching closely to see how the merger could reshape energy services in the region.
