Google Locks $4.3 Billion Nuclear Energy Deal to Power Surging AI Data Centers

Google Nuclear Energy Partnership Targets 890 Megawatts of New Capacity

Google has entered a strategic 20-year power purchase agreement with Constellation Energy to secure nuclear power for its expanding AI data centers2

2

. The deal brings 890 megawatts of new nuclear energy onto the PJM Interconnection grid, which serves approximately 67 million people across 13 Mid-Atlantic and Midwest states2

2

. Beyond this expansion, the companies struck a separate 15-year supply deal for an additional 2,700 megawatts powered by Constellation Energy's existing plants2

2

. While Alphabet Inc. has not disclosed the exact financial terms, sources familiar with the matter suggest the agreement is valued at $1 billion or more1

Constellation Energy Secures $4.3 Billion for Nuclear Infrastructure Upgrades

The nuclear power deal enables Constellation Energy to invest over $4.3 billion in upgrading and modernizing 11 nuclear power units across six facilities in Illinois, New Jersey and Pennsylvania2

2

. These upgrades include installing state-of-the-art turbines, modern steam generators and advanced digital control systems to boost plant efficiency2

2

. The agreement provides Constellation with revenue certainty needed to perform multibillion-dollar upgrades without increasing costs to consumers2

2

. First incremental capacity is expected to come online in 20283

3

. The contract will sustain 4,400 existing high-skilled operational and union positions while creating approximately 7,200 new construction jobs during the upgrade phase2

AI Data Centers Drive Massive Spike in Electricity Consumption

Google's electricity demand soared from 12.8 terawatt-hours in 2019 to 44 terawatt-hours in 20251

1

. Over 95 percent of Alphabet's total global electricity consumption goes directly to its AI data centers, with administrative offices and corporate campuses accounting for the remaining 5 percent1

1

. AI models demand continuous power that renewable sources like solar and wind cannot consistently provide because they depend on weather conditions1

1

. Nuclear energy offers steady carbon-free baseload power around the clock, making it attractive for hyperscalers power demands1

1

. Amanda Peterson Corio, Google's Global Head of Data Center Energy, emphasized that "the fastest new megawatt is often the one that can be provided by existing infrastructure," noting significant opportunity to unleash more nuclear capacity from the nation's existing nuclear fleet both quickly and cost-effectively2

. Microsoft backed the restart of Pennsylvania's Three Mile Island plant through a 20-year contract with Constellation1

1

. Meta Platforms has signed 20-year power purchase agreements with Vistra Corp, while Oracle plans to use nuclear power at its massive new data center project in Wisconsin2

2

. Google previously partnered with NextEra Energy to reopen Iowa's Duane Arnold reactor and invested in upgrades at two Southern Co. nuclear sites1

Coatue Management's $1.2 Billion Bet on Constellation Energy

Billionaire investor Philippe Laffont's Coatue Management held 4.63 million Constellation Energy shares worth approximately $1.15 billion as of June 30, representing about 2.37 percent of the firm's reported portfolio3

3

. The investment firm also held sizable positions in Alphabet Inc., Amazon, GE Vernova and Eaton Corp, suggesting Constellation represents one piece of a broader AI infrastructure thesis3

3

. Constellation shares jumped nearly 6 percent in premarket trading following the Google announcement, despite being down 26.93 percent year-to-date3

3

. CEO Joe Dominguez stated the company was "strengthening the nation's energy infrastructure" while meeting growing AI power demand, raising 2026 adjusted operating earnings guidance to $11.50-$12.50 per share3

Google Cloud Gains Constellation as Customer Through Energy Partnership

As part of the nuclear power deal, Constellation Energy signed a five-year contract with Google Cloud for computing resources and the Gemini Enterprise platform2

2

. The technology will aid Constellation in AI-driven site selection, outage management, critical infrastructure protection and generator dispatch optimization2

2

. To optimize grid connections, Google joined the AI Energy Management Alliance with Nvidia and grid software unicorn Emerald AI1

1

. The coalition uses Emerald AI's technology to enable demand response mechanisms that temporarily reduce or shift data center power usage during peak grid stress, potentially freeing up capacity for an additional 100 gigawatts of data center infrastructure1

Climate Goals Clash With Rising Greenhouse Gas Emissions

Alphabet set an ambitious goal to reach net-zero carbon emissions across all operations by 2030, yet its latest environmental report highlights an 81 percent surge in greenhouse gas emissions compared to the 2019 baseline1

1

. Driven by rapid AI growth over the past five years, the company secured over 12 gigawatts of net-new clean energy in 2025 alone1

1

. The long-term strategy focuses on advancing next-generation clean energy sources such as nuclear energy and enhanced geothermal, alongside strategic investments in commercial fusion power1

1

. Building brand-new nuclear reactors remains a slow process, leaving tech companies with little choice but to maximize capacity from existing infrastructure1

1

. With 94 nuclear reactors operating across the United States, there is significant opportunity to unleash more nuclear capacity from the nation's existing fleet2
