In 2022, Georgia Power projected its winter peak electricity demand would grow by about 400 megawatts by 2031. Since then, Georgia has experienced a boom of data centers, which require a large load of electricty to run, and Georgia Power's recent forecast shows peak demand growing by 20 times the 400-megawatt estimate from just three years ago.
