McIntosh Power Plant


Located in McIntosh, Ala., PowerSouth’s McIntosh Power Plant currently includes four natural-gas fired combustion turbines and the United States’ only Compressed Air Energy Storage (CAES) unit. 

The Plant's first two natural-gas units went commercial in 1998, with a capacity of 240 megawatts. The second set of two natural-gas units went commercial in 2010, with a capacity of 360 megawatts. The CAES facility has a capacity of 110 megawatts. Total plant capacity is 688 megawatts.

The natural-gas fired, simple-cycle units are classified as peaking units. They are designed to provide additional electricity to the PowerSouth system during “peak” usage periods — usually short periods of time during early morning or evening hours. The McIntosh Plant’s turbines and generators offer simple-cycle technology with short start-up time, making them suitable for continuous, peaking and emergency operation.
