Google Secures 890 MW Of Nuclear Power from Constellation Energy

Google secures 3,590 MW from Constellation, driving $4.3B in US nuclear upgrades.

What the company is saying

Google (NASDAQ:GOOG) has signed a 20-year power purchase agreement with Constellation Energy (NASDAQ:CEG) for 3,590 megawatts in the PJM Interconnection, the largest US power grid serving 67 million people. The company emphasizes that about a quarter of this supply—890 megawatts—will come from new nuclear energy, highlighting nuclear’s role as a continuous, base-load power source for its expanding data center and AI operations. Constellation frames the deal as enabling over $4.3 billion of investment in new equipment and technology at 11 of its nuclear units in Illinois, Pennsylvania, and New Jersey, aiming to increase both thermal and electrical efficiency. The announcement positions Google and its peers as leaders in reviving the US nuclear sector, referencing similar 20-year agreements with Amazon (690 MW), Meta (1,121 MW), and Microsoft, as well as Equinix’s microreactor deals. The tone is assertive, using figures and industry-wide projections to stress the urgency of securing reliable power amid surging data center demand. The company references PJM’s “bring your own power” policy and the 11-fold rise in capacity prices since 2024 to justify the scale and timing of these commitments.

What the data suggests

The disclosed figures confirm Google’s 3,590 MW contracted supply from Constellation, with 890 MW sourced from new nuclear generation. Constellation is committing over $4.3 billion to upgrade 11 nuclear units, with the first upgraded plant scheduled to deliver power in 2028. PJM Interconnection serves 67 million people and has experienced an 11-fold capacity price increase since 2024, reflecting acute supply-demand pressures. The US nuclear sector remains central, with 94 reactors producing about 782,000 GWh annually—18-19% of US electricity and 30% of global nuclear output. The 20-year PPAs with Amazon (690 MW) and Meta (1,121 MW) reinforce the trend of tech giants locking in long-term, large-scale, zero-carbon power. Some claims, such as the restart of NextEra’s Iowa plant for Google and Three Mile Island for Microsoft, lack contract specifics or timelines. Equinix’s microreactor agreements are described in broad terms, with no binding volume or delivery date. The data is robust for the main Google-Constellation deal, but ancillary claims are less substantiated.

Analysis

The announcement is positive in tone and discloses substantial, specific figures for contracted power (3,590 MW for Google, 690 MW for Amazon, 1,121 MW for Meta) and a $4.3 billion capital commitment by Constellation. However, the majority of the benefits—such as delivery of upgraded nuclear power—are not expected until 2028 or later, making the execution distance long-term. While the existence of signed 20-year PPAs is a strong operational milestone, there is no disclosure of immediate earnings impact, profitability metrics, or near-term cash flow effects. Several claims (e.g., plant restarts, Equinix microreactors) are forward-looking and lack detailed contractual or timeline specifics, inflating the narrative. The scale of capital outlay is large, but returns are uncertain and distant, and some claims about future grid impact and data center consumption are projections rather than realised facts.

Risk flags

• ●Execution risk is high due to the $4.3 billion capital commitment and the technical complexity of upgrading 11 nuclear units. Delays or cost overruns could materially affect returns and delivery timelines.
• ●Regulatory and permitting risk is significant for nuclear plant upgrades, as US nuclear projects face stringent oversight and potential legal or environmental challenges. Any setback could defer the 2028 delivery target.
• ●Market risk stems from the 11-fold increase in PJM capacity prices since 2024, indicating a volatile and tightening power market. If demand projections or policy frameworks change, contract economics could shift.
• ●Disclosure risk exists for ancillary claims—such as plant restarts for Google and Microsoft, and Equinix’s microreactor deals—which lack binding contract details or delivery timelines, making their realization uncertain.
• ●Long-term demand risk is present: while data center power needs are projected to double by 2030, actual growth may fall short of forecasts, potentially impacting the economics of these multi-decade agreements.

Bottom line

Google’s 3,590 MW, 20-year power deal with Constellation is a landmark move, driving over $4.3 billion in US nuclear investment and securing a quarter of supply from new nuclear sources. The agreement is a direct response to surging data center demand and PJM’s new policy requiring large users to secure their own power, as capacity prices have soared 11-fold since 2024. While the contract locks in long-term, zero-carbon electricity, the first upgraded nuclear output will not be delivered until 2028, so the financial and operational benefits are distant. The announcement is credible for the main Google-Constellation agreement, but other referenced deals—such as plant restarts and Equinix’s microreactor plans—lack detail and remain aspirational. Investors should focus on execution milestones for the nuclear upgrades, regulatory progress, and updates on actual delivery timelines. The most important takeaway is that securing reliable, large-scale power is now a strategic imperative for major tech firms, but the path to value realization is capital-intensive and long-dated.

Announcement summary

(NASDAQ:GOOG) Google has contracted 3,590 megawatts of power from Constellation Energy (NASDAQ:CEG) in the PJM Interconnection, the largest US power grid serving 67 million people across 13 states and Washington, D.C. Of this contracted supply, about a quarter, or 890 megawatts, will come from new nuclear energy sources. The 20-year power purchase agreement between Google and Constellation will enable investments in new equipment and technology at 11 Constellation-owned nuclear units located in Illinois, Pennsylvania, and New Jersey. These upgrades are intended to increase thermal and electrical efficiency, unlocking additional reliable, firm power for the grid. Constellation will make over $4.3 billion of new investments in its nuclear fleet as part of the agreement. Electricity from the first of the upgraded plants is scheduled to be delivered in 2028. The deal is a response to PJM’s “bring your own power” proposal, which requires data center customers to secure their own power or risk being disconnected during peak demand. PJM capacity prices have increased more than 11-fold since 2024 due to rising electricity demand, largely from data center expansion, resulting in a power shortfall. Google has also contracted to restart NextEra Energy’s (NYSE:NEE) nuclear power plant in Iowa. Constellation has agreed to restart its Three Mile Island reactor in Pennsylvania to serve Microsoft’s (NASDAQ:MSFT) data centers. Constellation has a 20-year power purchase agreement announced September 30 with Amazon (NASDAQ:AMZN) to supply 690 megawatts from its Calvert Cliffs nuclear plant in Maryland, and a 20-year virtual PPA with Meta (NASDAQ:META) for 1,121 megawatts of power. In August, Equinix (EQIX.O) announced agreements to secure advanced nuclear electricity, including power purchase agreements and a pre-order for microreactors, expected to provide more than one gigawatt of electricity to its data centers. The United States accounts for roughly 30% of global nuclear electricity generation, with 94 operating reactors producing about 782,000 gigawatt-hours annually, supplying nearly 18-19% of the country’s total electricity. The last new nuclear reactor built in the US is Vogtle Unit 4 in Burke, Georgia, which began commercial operation in April 2024. Other significant nuclear states mentioned include France, China, Russia, and South Korea.
