To support its expanding U.S. operations, Google has finalized a USD 4.3 billion contract with Constellation Energy to acquire 890 megawatts of additional nuclear power. Spanning 20 years, the power purchase agreement will fund modernization efforts at operational nuclear facilities located in Illinois, New Jersey, and Pennsylvania.
Following Tuesday’s announcement, Constellation Energy stock surged more than 12%. Alphabet, Google’s parent company, saw little movement in its share price.
This accord will fuel over USD 4.3 billion in fresh investments by Constellation, which intends to execute enhancements across multiple nuclear reactors situated throughout the Midwest and Mid-Atlantic.
The scheduled work involves updating turbines, steam generators, and digital control systems. Collectively, these modernizations will boost energy generation from reactors already integrated into the American power network.
Google Nuclear Power Deal Expands Existing Reactor Capacity
Google stated that the deal grants Constellation the financial predictability necessary to invest in 11 nuclear units spread across Illinois, Pennsylvania, and New Jersey.
Additionally, Google noted that these upgrades will not impose any extra charges on everyday electricity consumers. The tech giant is working to secure fresh energy sources as artificial intelligence drives up overall power consumption.
The 11 reactors function within the PJM Interconnection grid, which is the country’s largest electric grid and spans 13 states containing major data center hubs. Furthermore, Google and Constellation established a separate 15-year supply pact covering an additional 2.7 gigawatts of electricity.
As part of this comprehensive partnership, Constellation will implement Google’s Gemini Enterprise software to assist with site selection, outage handling, and infrastructure safeguarding. This arrangement merges clean energy procurement with operational software as the two firms deepen their collaboration.
AI Data Centers Drive Big Tech Toward Nuclear Energy
Major technology corporations are aggressively pursuing larger energy supplies to power the rapid construction of data centers across the United States. These facilities are required to run increasingly energy-demanding artificial intelligence architectures.
Google has previously backed nuclear initiatives in Georgia, Iowa, and Tennessee, alongside securing a contract to revive a NextEra Energy nuclear facility in Iowa.
Constellation has forged comparable partnerships with other tech giants. Previously, the company announced intentions to bring a closed Three Mile Island reactor in Pennsylvania back online to supply Microsoft data centers. Microsoft entered into a 20-year pact with Constellation in 2024, anticipating power deliveries from the dormant reactor by 2028.
In January, Amazon also secured a nuclear energy contract with Constellation, while Meta finalized a separate 20-year deal to buy power from Vistra’s nuclear plants.
Beyond traditional reactors, tech firms are investing in small modular reactors—compact units designed to generate power on a smaller scale than standard nuclear stations.
According to materials released with the announcement, a single gigawatt is capable of powering roughly 800,000 homes.

PJM Power Rules Shape Google’s Energy Strategy
Google’s pact also addresses shifting regulations under evaluation by PJM Interconnection, where grid administrators have floated new mandates for large data center clients.
Under this pending proposal, data centers tied to the 13-state network might be required to supply their own power generation. Failure to do so could result in operators remotely cutting off their grid access during peak demand periods.
Both Google and Constellation confirmed that their arrangement is designed to align with PJM’s proposed bring-your-own-power guidelines.
This strategy grants Google access to extra electricity while simultaneously financing enhancements for nuclear units already supporting the regional grid. Google emphasized its ongoing dedication to investing in dependable, lower-carbon power sources to sustain its growth.
“We’re committed to meeting our growth responsibly by actively investing in clean, reliable power that brings new capacity to our nation’s grids,” said Amanda Peterson Corio, Google’s global head of energy and power.
While nuclear generation yields zero carbon emissions unlike conventional fossil fuels, it continues to encounter public apprehension and historical industry stigma.
This newest arrangement brings Google an additional 890 megawatts of nuclear capacity while lengthening its alliance with Constellation through a separate 2.7-gigawatt supply commitment.
Final Thoughts
Google’s USD 4.3 billion partnership with Constellation Energy will deliver 890 megawatts of new nuclear capacity and facility upgrades across 11 reactors. Alongside a separate 2.7-gigawatt supply accord, the agreement underpins Google’s strategy to secure dependable energy for its expanding AI data centers.
