The power plant is often still referred to by locals as PSI, in reference to its original owner, Public Service Indiana, even when it was owned by Cinergy. The plant's two new 620 ft (190 m) smokestacks are seen in the back, behind its four original 550 ft (170 m) stacks. All six stacks are shown.

The Gibson Generating Station is a coal-burning power plant located at the northernmost end of Montgomery Township, Gibson County, Indiana, United States. It is close to the Wabash River, 1.5 miles southeast of Mount Carmel, Illinois, 2 miles south of the mouth of the Patoka River, and 4 miles south of the mouth of the White River. The closest Indiana communities are Owensville 7.5 miles to the southeast of the plant, and Princeton, 10.5 miles to the east. With a 2013 aggregate output capacity among its five units of 3,345 megawatts, it is the largest power plant run by Duke Energy, the third-largest coal power plant in the world, and the tenth-largest electrical plant in the United States, With the reduction of Nanticoke Generating Station, it became the largest coal power plant in North America by generated power late in 2012. Also on the grounds of the facility is a 3,000-acre (12 km2) large man-made lake called Gibson Lake which is used as a cooling pond for the plant. Neighboring the plant is a Duke-owned, publicly accessible access point to the Wabash River near a small island that acts as a wildlife preserve. This is the nearest boat-ramp to Mount Carmel on the Indiana side of the river. Located immediately south of Gibson Lake, the plant's cooling pond, is the Cane Ridge National Wildlife Refuge, the newest unit of the Patoka River National Wildlife Refuge and Management Area. Opened in August 2006, this 26-acre (11 ha) area serves as a nesting ground for the least tern, a rare bird. Cane Ridge NWR is reportedly the easternmost nesting ground for the bird in the U.S. The Gibson Generating Station is connected to the power grid via five 345 kV and one 138 kV transmission lines to 79 Indiana counties including the Indianapolis area and a sixth 345 kV line running from GGS to Evansville and Henderson, owned by Vectren and Kenergy.
