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 (2.5 km) southeast of Mount Carmel, Illinois, 2 miles (3.2 km) south of the mouth of the Patoka River, and 4 miles (6.5 km) south of the mouth of the White River. The closest Indiana communities are Owensville 7.5 miles (12 km) to the southeast of the plant, and Princeton, 10.5 miles (17 km) 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, and the tenth-largest electrical plant in the United States. Given the closure of the Nanticoke Generating Station in Ontario, in 2013, the Gibson Generating Station became the largest coal power plant in North America by generated power.
