Google and Constellation Energy said on 6 October 2026 that they have agreed a long-term clean energy collaboration to bring 890 megawatts (MW) of additional nuclear capacity to the PJM grid. Constellation’s release describes a 20-year power purchase agreement that “represents more than $4.3 billion of new investment by Constellation”; Google says the uprate projects will add the capacity “before the end of 2032”. The two documents we read give no price for the power.
Business Pill · THE BUYER WHO LETS OTHERS BUILD
A one-minute explainer of the idea behind this story: an anchor customer. It teaches the concept, not this story’s figures.
The key insight: Constellation’s release puts a dollar figure and a tenor next to the capacity: a 20-year agreement and “more than $4.3 billion of new investment by Constellation” for 890 MW. Google’s post gives neither, and describes Google as the “anchor customer”. We set the statements next to each other as the two documents give them; neither gives the priceGoogle will pay for the power.
Constellation says the 20-year power purchase agreement “will enable investments in new equipment and technology at 11 Constellation-owned nuclear units in Illinois, Pennsylvania, and New Jersey”. Google describes the same project as financing for upgrades at “six operating nuclear plants across Illinois, Pennsylvania, and New Jersey”.
Google explains an uprate this way: “A nuclear uprate modernizes turbines, steam generators, and digital control systems to boost the power output of an existing reactor.” It says that by serving as the anchor customer for these uprate projects it is providing “the long-term revenue certainty Constellation needs to invest in upgrades for 11 of their nuclear reactors”.
On timing, the two documents give different markers. Constellation lists the “first uprate expected to be delivered by 2028”. Google says that “Before the end of 2032” the projects will add 890 MW of “firm, 24/7 clean power” to the PJM grid.
Both documents give the same employment figures: roughly 4,400 existing jobs sustained and approximately 7,200 new construction jobs. These are the companies’ own estimates.
What Google’s post and Constellation’s release give for the 6 October 2026 agreement: 890 MW of additional nuclear capacity, a 20-year power purchase agreement and more than $4.3 billion of investment (Constellation’s release). Neither document gives the price for the power.
The Second Deal Inside Constellation’s Release
Constellation says the companies also “entered into a 15-year energy supply agreement for an additional 2,700 MWs in PJM’s fleet”. It describes the purpose this way: “This financial structure ensures that Constellation’s operating generation assets continue to deliver energy and capacity to the PJM market.”
In its list of key elements, Constellation calls this “Revenue certainty”, saying it “ensures existing assets remain economically viable without taking resources off of the grid”. Google’s post does not mention the 2,700 MW agreement.
The AI Part of the Agreement
Google says Constellation “is deploying Google Cloud’s Gemini Enterprise agentic workflows across its core operations to accelerate uprate planning, streamline construction, and optimize plant output”.
Constellation calls it an “expanded five-year technology alliance” to establish an “AI for energy” blueprint, with three initial focus areas. The first is speed to power: “AI for intelligent site selection, power flow modeling, permitting and interconnection planning”. The second is generation optimization: “Asset health monitoring, outage and turnaround management, and scenario optimization to speed up construction”. The third is protecting critical infrastructure, using Google Cloud’s “defense-grade platforms for highly regulated work, used to secure operational technology (OT) networks”.
Constellation also lists a strategic framework “to evaluate opportunities to develop new clean generation, storage and demand response across the United States to support Google’s growth”. It says the framework “is intended to identify potential projects”, which makes it a plan to look for projects, not a set of projects.
How Google Frames the Scale
Google says that with this agreement it “has now enabled over 1.5 GW of new nuclear capacity for the U.S. energy system” from “increasing the power output of existing reactors and bringing dormant facilities back online”.
It also cites the U.S. Department of Energy’s goal of 5 GW of domestic nuclear expansion by 2030 through uprates and restarts, and says that by the end of the decade its agreements “are expected to enable nearly 25% of this national goal”. We set the two figures side by side as Google gives them and do not reconcile them.
Google’s post also lists agreements in Georgia (Georgia Power, uprates across four reactor units), Iowa (restarting the Duane Arnold Energy Center with NextEra Energy, “over 600 MW”) and Tennessee (Kairos Power and the Tennessee Valley Authority, advanced reactors).
Constellation says the agreement offers “a direct response to PJM’s” “Bring Your Own Power” proposal, and that it “aligns with” the White House Ratepayer Protection Pledge.
What the Executives Said
Constellation’s release quotes Amanda Peterson Corio, Google’s global head of energy and power: “Our agreement with Constellation to fund nuclear reactor uprates will strengthen the PJM grid, which serves 67 million people, all while protecting energy affordability and supporting local union jobs.”
It quotes Joe Dominguez, Constellation’s chairman, president and CEO: “This long-term clean energy collaboration with Google can serve as a model for how technology companies and the energy industry can work together to responsibly develop the digital economy and invest in our nation’s energy infrastructure in a way that delivers grid-wide benefits for all, funded by private entities.”
The Structural Read
The two documents describe the same project from different sides. Google’s post is about capacity and about Google’s role: it calls itself the “anchor customer” providing “long-term revenue certainty”. Constellation’s release carries the contract facts: a 20-year agreement, 11 units, more than $4.3 billion of investment and a separate 15-year, 2,700 MW agreement.
The capacity and the dates carry the qualifiers each document gives them. Constellation says the “first uprate” is “expected to be delivered by 2028”; Google says the 890 MW arrives “Before the end of 2032”. In the documents we read, neither says how much of the 890 MW arrives in each year.
The AI part is described as a separate five-year technology alliance. Constellation calls it an “AI for energy” blueprint, and Google says Constellation is deploying Gemini Enterprise “agentic workflows across its core operations”. Neither document ties a dollar amount to the technology alliance.
Joe Dominguez, chairman, president and CEO of Constellation, in the release
“Preserving and expanding the output of the existing nuclear fleet and developing new clean generation is critical to meeting our nation’s growing energy needs while keeping costs affordable for homes and businesses.”
Three Implications
THE MONEY FIGURE BELONGS TO CONSTELLATION Constellation’s release says the agreement “represents more than $4.3 billion of new investment by Constellation”. Google’s post gives no dollar figure for this project and does not say what Google pays.
THE TENORS ARE IN THE RELEASE, NOT THE POST The 20-year power purchase agreement and the 15-year, 2,700 MW supply agreement appear in Constellation’s release. Google’s post does not mention the 2,700 MW agreement and does not state the length of the power purchase agreement.
THE CAPACITY IS A PLAN WITH DATES Both documents give dates as expectations: the first uprate by 2028 and the full 890 MW before the end of 2032. The release and the post describe uprates that have not yet been delivered.
What Is Not Established
We read Google’s blog post and Constellation’s release in full. Neither gives a price or a price per megawatt-hour for the power Google will buy, or a payment schedule. The tenors appear only in Constellation’s release: 20 years for the power purchase agreement and 15 years for the 2,700 MW supply agreement.
Google describes “this financing” and calls itself the anchor customer; Constellation describes the $4.3 billion as new investment by Constellation. Neither document breaks down how that investment is financed.
The dates are expectations, not deliveries: Constellation expects the first uprate by 2028, and Google says the 890 MW arrives before the end of 2032. Google’s “over 1.5 GW” counts capacity from uprates and restarts that it says it has enabled, and its “nearly 25%” is its own expectation for the end of the decade.
We did not read any regulatory filing, any statement from PJM or the Department of Energy, or anything later than the two documents, and we did not contact either company. For other recent power announcements, see our pieces on the TeraWulf Muskie release and the Applied Digital Finland release.

The Map of AI places more than 200 companies across nine layers of the stack, from silicon to application. It shows the layers that sit beneath the applications people use every day.
Google and Constellation said on 6 October 2026 that they have agreed a long-term collaboration to add 890 MW of nuclear capacity to the PJM grid through uprates at 11 Constellation-owned units. Constellation describes a 20-year power purchase agreement and more than $4.3 billion of new investment by Constellation, plus a separate 15-year, 2,700 MW supply agreement, and says the first uprate is expected by 2028; Google says the capacity arrives before the end of 2032.
Constellation also describes an expanded five-year technology alliance under which it deploys Gemini Enterprise. The documents we read give no price for the power.

A note on sourcing. This piece rests on Google’s blog post and Constellation’s press release, both of 6 October 2026 and both read in full. We haven’t checked either company’s claims independently, and we did not contact Google, Constellation, PJM or the Department of Energy. We draw no conclusion beyond what the two companies say. Nothing here predicts anything or is investment advice.
