The Kemper County Energy Facility is a lignite-fueled integrated gasification combined-cycle (IGCC) facility. The plant design incorporates the air-blown TRIG™ technology jointly developed by Southern Company, KBR, and DOE.

Mississippi Power Company, a Southern Company subsidiary, owns and operates the plant.

The facility was supposed to employ emissions control equipment to produce marketable byproducts of ammonia, sulfuric acid, and CO2. Over 65 percent of the CO2 was supposed to be captured, and used for EOR.

On June 28, 2017, Mississippi Power Co. announced the company was suspending start-up and operations activities involving the lignite gasification portion of the Kemper County energy facility as an appropriate step to manage costs given the economics of the project.
