What does Southern Company do?

Southern Company is one of the largest U.S. electric utilities, serving roughly 9 million customers across the Southeast through subsidiaries including Georgia Power and Alabama Power. Its Georgia Power unit is at the center of a national debate over data center electricity demand, with a newly upheld expansion plan worth up to $60 billion and a pipeline of 75 gigawatts of data center interest positioning the company as a primary beneficiary of surging AI-driven power needs. The company's raised $81 billion five-year capex plan and back-to-back analyst upgrades are directly tied to today's continued rally.
