The Public Service Commission of South Carolina has approved a proposal by Duke Energy to build a new natural gas power plant in Anderson County, marking the company’s first new generation project in the state in more than a decade.
The combined-cycle facility, with an estimated capacity of about 1,365 megawatts, is expected to begin construction in summer 2027 and enter service by early 2031.
The project is the first to be approved following the passage of the Energy Security Act, which was enacted to guide long-term energy planning as the state experiences rapid population and economic growth.
According to Duke Energy, the facility will be among the most efficient natural gas plants in its system and will incorporate advanced environmental controls. The plant is expected to use about 90 per cent less water than traditional wet-cooling facilities, eliminate visible vapor plumes and reduce the need for chemical water treatment.
The development is also expected to generate significant economic activity. A study by Ernst & Young estimates the project will support more than 2,200 jobs annually during construction, including 746 positions in Anderson County. Once operational, it is projected to contribute $84 million annually to the state economy, supporting 125 jobs and $10 million in labour income.
Ownership of a portion of the facility’s output will be shared, with Central Electric Power Cooperative and North Carolina Electric Membership Corporation set to hold 95 MW and 100 MW interests, respectively.
The approval follows a public review process that included hearings and community engagement sessions in Anderson County.
South Carolina Gov. Henry McMaster said the project is key to meeting rising energy demand.
“As South Carolina continues to attract new businesses and new residents at a record pace, the need for dependable energy has never been more urgent,” McMaster said. “This project reflects the kind of forward-thinking planning that will ensure we meet those needs with reliable, efficient power for years to come.”
Duke Energy said the new facility will play a critical role in supporting grid reliability and meeting growing demand across the region.
