Georgia Power is asking state regulators to clear more than 10,000 megawatts of new capacity over the next six years, a roughly 50 percent lift in its fleet. The utility pegs the spend at more than $15 billion (C$21 billion), with about 80 percent tied to data centres serving artificial intelligence and cloud computing.
A final vote is scheduled for December 19, with commissioners weighing reliability needs against the risk of overbuilding if projected contracts fall short. Staff testimony frames the choice as a balance between near term megawatts and long term bill impacts. The stakes are high for ratepayers and for Georgia’s surge of digital investment.
Staff urge tighter staging
Regulatory staff have urged a staged approach, starting with contracted loads and a cap at 7,400 megawatts by March 2026. That guidance would favour purchased power and deferrals over building new utility‑owned plants in one push.
Staff analysis also warns that the build could add about $20 a month to a typical household bill if costs land on customers without matching load. Skeptics highlight stranded asset risk if data centre timelines slip.
“The rest is speculative and exposes customers to the risk of stranded costs,” wrote Robert Trokey.
Georgia Power’s filing comes after a rapid reset in regional load forecasts tied to hyperscale computing, manufacturing and winter peaks. The utility says most new demand is identifiable and under negotiation, with long term agreements designed to shield other customers. Backers argue early approvals will keep projects from migrating to neighbouring grids. They also say larger procurements can lock in supply and schedule.
Contracts drive utility’s argument
Georgia Power told regulators it selected much of the requested capacity through an all‑source tender, building on its approved 2025 resource plan. In July, it sought certification for approximately 9,900 megawatts, most chosen from competitive bids aimed at winter needs between 2029 and 2031. The portfolio points to flexible gas turbines, storage, and purchased power, alongside deferred coal retirements to maintain reserve margins. Georgia Power insists the scale is necessary to keep service reliable during extreme weather and fast industrial growth.
The utility also leans on its development pipeline and signed deals as proof of need. Executives say contracted data centre load provides revenue certainty and cost recovery signals.
“We plan for tomorrow, the next ten years and decades to come,” said Kim Greene. Supporters inside the state’s economic agencies view firm power as a precondition for land, fibre and water investments already underway.
The commission’s ruling will set where risk sits if demand underperforms, and how fast new plants move from plan to shovel. One path would grant capacity tied to executed contracts first, then expand as commitments convert.
Another would approve a larger tranche now, betting that procurement discipline and penalties can protect bills. Staff prefer the first path, while Georgia Power warns delay could push projects and raise costs. The outcome will signal how Southeastern regulators treat data centres as anchor customers, and how far utilities can scale ahead of load.
If the vote follows staff recommendations, the near term build would be smaller and more modular. If it follows Georgia Power’s request, construction and interconnections could accelerate into 2026 and 2027.
Either way, the file underscores how AI era infrastructure is redrawing power plans and procurement calendars. The December decision will show how that pressure translates into rate design and project delivery, starting with a firm ceiling at 7,400 megawatts by March 2026.
