Strengthening Energy Resilience for the U.S. Army with 13-MW Solar Project

Onyx Renewables completed two ground-mount solar projects totaling 13 megawatts (MW) at Fort Polk in Leesville, La., in August 2025. Developed in partnership with sustainable infrastructure solutions provider Corvias, the projects were celebrated with a ribbon-cutting ceremony attended by Onyx, Corvias, the U.S. Department of Defense, community leaders, and other key stakeholders.

The solar arrays are scheduled for energization this fall, and Onyx will finance, own, and operate the systems long term.

In collaboration with the U.S. Army, Onyx and Corvias developed these projects to provide a predictable electric rate to the military installation while also advancing the Army’s energy goals. The projects will leverage renewable energy generation that can support the military installation’s energy resiliency, with the addition of battery storage and microgrid controls in the future.

“By increasing onsite energy capacity with distributed resources, we are not only bolstering crucial resilience across the base but also generating savings that will benefit the military community stationed there.”
— Kevin Cox, SVP of Origination, Onyx Renewables

The Fort Polk solar projects, which are collocated on one parcel spanning 97 acres, will provide energy cost savings over a 25-year power purchase agreement (PPA) term. In addition to promoting energy security and resiliency, the projects are anticipated to meet 42% of the electricity demand for on-base housing in their first year.  

Building on their successful track record of developing distributed generation (DG) assets for the U.S. Army at bases such as Fort Riley, this latest milestone at Fort Polk underscores Onyx and Corvias’ collective determination and ability to drive sustainable energy solutions forward. The companies’ extensive experience in navigating complex regulatory landscapes has been instrumental in advancing this landmark renewable energy project in Louisiana.
