The XVIII Airborne Corps and Fort Liberty hosted senior leaders from the White House Council on Environmental Quality, Department of Defense (DoD) and Duke Energy on June 18 to announce a historic procurement of carbon-free electricity (CFE) in North and South Carolina.

The DoD has signed on to Duke Energy’s Green Source Advantage (GSA) program to provide renewable energy on behalf of the five largest DOD major military installations across North Carolina and South Carolina, including Fort Liberty, USMC-Camp Lejeune, USMC-Cherry Point, USAF Seymour Johnson and USAF Shaw.

The DoD's participation in the GSA program will provide an estimated 135 megawatts and approximately 4.8 million megawatt-hours of renewable energy in both states over a 15-year delivery period from two newly constructed off-site solar facilities in South Carolina. The facilities will be developed, owned and operated by energyRe, subject to local and state approvals. The projects are expected to become operational in the fourth quarter of 2026.

“This project is a great opportunity to assist our military departments and our warfighters in their decarbonization goals and is paramount to reaching our initial goals of Executive Order 14057, Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability. DLA Energy is committed to supporting the administration’s clean energy initiatives and helping the military services and whole-of-government partners achieve their climate change goals,” said United States Air Force Col. Jennifer Neris, director of carbon pollution-free electricity for the Defense Logistics Agency, in a press release.

Duke Energy’s GSA program, which supports renewable energy development, provides large nonresidential customers the opportunity to offset their power purchases by securing renewable energy from projects connected to the Duke Energy grid. The customer receives the renewable energy certificates (RECs) generated by the projects to satisfy sustainability and/or renewable, carbon-free energy goals. Customers are credited for the solar power the facility generates against their energy purchased from the Duke Energy grid.

“As our large business customers plan for the future, they also have increasingly specific goals around decarbonization and require access to renewable energy sources that can support those needs,” said Meghan Dewey, vice president of Products and Services for Duke Energy, in a press release. “Duke Energy continues to expand its scope of customer options and programs built with critical stakeholder feedback to enable these customers and prospective customers to meet their sustainability goals.”

Executive Order 14057 has established targets for federal agencies to reach 100% carbon-free electricity by 2030, with 50% matching on a 24/7 basis. 

In addition to the announcement on June 18, visitors received a tour of a 1.1-megawatt floating solar array on Big Muddy Lake that the Army has developed in partnership with Duke Energy. Although separate from the new CFE purchase, the floating solar array provides Fort Liberty access to on-site resilient CFE generation and storage, an example of the results of Army’s energy resilience partnership with Duke Energy.
