Southern Co.'s 11 GW Data Center Pipeline Drives Record Quarterly Electricity Sales

According to Utility Dive, Southern Company posted 2.3% year-over-year growth in retail electricity sales for Q1 2026, driven by a 42% increase in data center power consumption compared to the same period in 2025.

Market Impact

Southern Company CFO David Poroch called the 2.3% growth “the highest total retail sales growth that we’ve seen in the first quarter in recent history,” adding that the commercial class grew 4.5% when adjusted for weather. CEO Chris Womack described “incredible momentum and tangible interest for power from large load customers.”

The company now holds 28 large load projects representing 11 GW under contract, up from 26 projects at 10 GW at the end of 2025. Beyond signed contracts, Southern is finalizing another 6 GW of large load customers and claims a prospective pipeline of 75 GW. Georgia Power’s Q1 capital expenditures rose from $1.6 billion to more than $2 billion year over year. Georgia Power also filed a request with regulators last week seeking 2 GW to 6 GW in new all-source capacity, including thermal generation, energy storage, and battery storage plus renewables. Southern Company also closed a $26.5 billion Department of Energy loan package in February to build or upgrade more than 16 GW of firm, reliable power, including 5 GW of new gas generation and 6 GW in nuclear improvements through uprates.

What It Means for Subcontractors

• Georgia Power’s Q1 capex jump to $2 billion signals sustained, large-scale construction demand in the Southeast. Field service companies operating in Georgia, Alabama, and Mississippi should be positioning now for subcontract opportunities across transmission, distribution, and generation projects.
• Southern’s request for 2 GW to 6 GW in new all-source capacity, including thermal, storage, and renewables, means multiple project types will be tendered. Subcontractors with cross-discipline capabilities in gas, battery storage, and renewables have a competitive edge.
• The $26.5 billion DOE loan package backs long-term construction activity. Subcontractors should track which prime contractors and EPC firms Southern Company and Georgia Power award work to, as that is where subcontract flow-down opportunities will originate.
• Southern’s 75 GW prospective pipeline is not contracted yet, but the 11 GW already under contract represents years of near-term construction work. Companies that build relationships with Southern’s procurement teams today will be better positioned when that pipeline converts to signed projects.
