Alphabet (GOOGL.US) has agreed to fund a capacity increase at two nuclear plants operated by a subsidiary of Southern Company (SO.US), adding roughly 96 megawatts of power supply as data centers push electricity demand higher. Under a new rate arrangement announced on Monday, Google will finance the so-called "uprate" of the Vogtle and Hatch nuclear plants in Georgia — a process that expands reactor output through measures such as replacing mechanical components.
Georgia Power, a subsidiary of Southern Company, jointly owns the Vogtle and Hatch facilities, while the parent's Southern Nuclear arm manages their operations. The arrangement is still subject to regulatory approval.
The deal comes amid growing questions over who should bear the cost of new electricity infrastructure needed to satisfy surging demand. Georgia Power said its agreement with Google would help shield residential and other industrial customers from the upgrade costs.
Similar precedents exist: last year, Constellation Energy agreed to sell power from one of its Illinois nuclear plants to Meta Platforms while investing in infrastructure improvements at that facility.
Nuclear power has emerged as one of the biggest beneficiaries of the AI-driven surge in electricity demand due to its ability to provide round-the-clock carbon-free energy. Upgrading existing plants typically takes far less time than the multi-year cycles required for new builds.
The broader context: how big tech is racing into nuclear
This uprate investment is the latest step in Google's nuclear strategy. In October 2024, Google signed an agreement with Kairos Power — the world's first corporate deal to purchase power from multiple small modular reactors (SMRs) — targeting up to 500 megawatts of advanced nuclear capacity by 2035. The first reactor, Hermes 2 in Oak Ridge, Tennessee, is slated to come online in 2030, with power delivered via the Tennessee Valley Authority (TVA) grid to Google's data centers in Tennessee and Alabama.
Competitors acted even earlier. In September 2024, Microsoft signed a 20-year, 835-megawatt power purchase agreement with Constellation Energy, paving the way for the restart of the Three Mile Island Unit 1 reactor in Pennsylvania (the Crane Clean Energy Center). In June 2025, Meta inked a 20-year deal with Constellation Energy for the Clinton Clean Energy Center, locking in 1,121 megawatts of carbon-free power starting June 2027, plus an additional 30 megawatts from an uprate — this is the "Illinois nuclear plant" referenced earlier.
The uprate logic has even been applied to new projects: Kairos subsequently raised Hermes 2's per-reactor output from 28 megawatts to 50 megawatts.
The demand-side gap is significant. Goldman Sachs has estimated that U.S. data center electricity consumption will roughly triple between 2023 and 2030, requiring approximately 47 gigawatts of new generating capacity.
The tight supply situation has also spilled into pricing: capacity auction prices across several U.S. power markets have repeatedly hit record highs in recent years, and long-term power purchase agreements with tech giants are creating a new revenue model for existing nuclear units.
Why uprates are the fast lane
Uprates count as a fast path because they avoid the lengthy timelines of new builds: typically, replacing turbine blades, upgrading generator components, or renewing instrumentation and control systems can squeeze out several percentage points of extra output from an operating unit. Costs and timelines are measured in "years" and "hundreds of millions," rather than the decade-plus and tens-of-billions typically required for new plants, according to common industry practice.
The 96-megawatt scale is modest relative to the multi-gigawatt capacity of Vogtle, but it becomes precious during grid-tight periods — roughly equivalent to the electricity demand of tens of thousands of homes based on average U.S. household load.
Georgia's Vogtle plant itself stands as a symbol of America's nuclear renaissance: its Units 3 and 4 entered commercial operation in July 2023 and April 2024 respectively, marking the country's first newly built nuclear reactors in decades. The final construction cost exceeded $30 billion and the schedule ran severely over budget.
That history explains why the uprate fast lane holds particular appeal for tech companies — no ten-year waits, just retrofits and upgrades to existing units.
Georgia sits on the front line of this electricity race: the Atlanta metropolitan area has become one of the fastest-growing data center markets in the U.S., and Georgia Power has previously disclosed a queue of large-load customer requests measured in tens of gigawatts. In early 2025, state regulators began revising rate rules for large-load customers, requiring tech and industrial users to shoulder more infrastructure costs. The new rate arrangement with Google can be seen as an extension of this regulatory direction.
The logic behind the nuclear sprint is straightforward: wind and solar can be connected to the grid quickly, but suffer from intermittency. Nuclear's around-the-clock baseload characteristics align perfectly with data centers' 24/7 load profile — which explains why tech giants' clean power procurement has tilted notably toward nuclear in recent years.
The cost-sharing debate plays out in Georgia
The question of who pays is also playing out in Georgia: Georgia Power has expanded its electricity investment in response to surging data center load, while the pressure of residential rate increases and the regulatory debate over "large users bearing their own costs" continues.
Whether this new rate arrangement gets approved will be the latest test of that debate — if approved, it would embed the "large user pays" principle into the rate structure in the form of "uprate financing."
The statement did not disclose the consideration Google is paying, nor the terms under which Google would receive the additional power.
