Southern Company, a major electric and gas utility in the U.S. South, has increased its five-year spending plan by 7% to $81 billion (2026-2030), with half of that capital dedicated to boosting power generation to meet skyrocketing demand from data centers and industrial manufacturers. The utility is seeing unprecedented interest from "large-load" customers like Microsoft and Google, with 75 gigawatts of potential demand in the pipeline - enough to power over 50 million homes.

Why it matters

U.S. utilities have invested heavily to upgrade electric grids as they face extreme weather and growing demand from power-hungry data centers dedicated to AI and cryptocurrency, alongside a shift by homes and businesses toward electric heating and transport. This investment by Southern Co highlights the broader trend of utilities needing to rapidly expand generation capacity to meet the needs of the digital economy and energy transition.

The details

Southern Co has increased its five-year spending plan by 7% to $81 billion (2026-2030), with about half of that spending going to boosting power generation. The utility said it had contracted 10 gigawatts of large-load customers across Alabama, Georgia and Mississippi, including Google, Meta, Microsoft and Compass Datacenters. Data centers with a combined demand of around 75 gigawatts have expressed interest in connecting to Southern Co's system. To meet this demand, the company plans to redirect about 1,000 megawatts of natural gas-fired generation capacity by 2030 and increase the output of its existing natural gas fleet by an additional 700 megawatts.

  • Southern Co's five-year spending plan covers the period from 2026 to 2030.
  • The company posted its quarterly results for the period ended December 31, 2025.
