Google Just Locked In 3.6GW of Power as AI’s Energy Demand Keeps Growing

Google has signed one of its biggest power agreements yet as the electricity demands of AI and data centers continue to rise.

Google and Constellation Energy announced a long-term collaboration covering 3,590 megawatts of power in the PJM Interconnection region of the United States.

The deal includes 890MW of new nuclear capacity created through upgrades at existing reactors, plus a separate 2,700MW, 15-year energy supply agreement.

Where the 3.59GW Comes From

The agreement has two major pieces.

The first is a 20-year power purchase agreement intended to support upgrades across 11 Constellation nuclear units in Illinois, Pennsylvania, and New Jersey.

Those upgrades are expected to add 890MW of new nuclear generation capacity to the grid.

Constellation says the added capacity is comparable to the output of a large new conventional reactor, but it will come from upgrading existing plants instead of building a new site from scratch.

The second part is a 15-year agreement for 2,700MW of additional power supply from Constellation's PJM fleet.

Together, those agreements total 3,590MW.

This Is Not 3.59GW of New Nuclear Power

That distinction is important.

Only the 890MW portion represents new nuclear capacity created through plant upgrades.

The additional 2,700MW is a separate supply agreement designed to support the continued operation of existing generation assets.

So describing the entire 3.59GW deal as new nuclear generation would be inaccurate.

Why Google Needs So Much Power

AI infrastructure consumes enormous amounts of electricity.

Training large models, serving AI requests, operating cloud platforms, and running increasingly dense data centers all contribute to rising power demand.

Google says the agreement is part of its effort to meet growth responsibly while adding new capacity to the grid.

Constellation and Google also frame the project as a response to PJM's push for large power users to help bring new electricity supply alongside their own expansion.

Why Nuclear Is Attractive to Data Centers

Data centers need power around the clock.

Solar and wind can provide large amounts of clean electricity, but their output changes with weather and time of day.

Nuclear plants provide steady generation, which makes them attractive for companies trying to support large, continuous computing loads while reducing carbon emissions.

Instead of waiting years for entirely new reactors, Constellation plans to increase output from existing plants through equipment and efficiency upgrades.

The first additional capacity is expected to arrive in 2028.

The Investment Is Bigger Than the Power Contract

Constellation says it plans to invest more than $4.3 billion into the nuclear upgrades.

The company says the work will support roughly 4,400 existing jobs and create around 7,200 construction jobs during the build period.

The agreement also includes a broader strategic framework for Google and Constellation to explore new power generation, energy storage, and demand-response projects in the future.

Google Is Also Bringing AI Into the Energy Business

The partnership is not only about buying electricity.

Constellation also selected Google Cloud and Gemini Enterprise as part of an expanded five-year technology agreement.

The companies say they plan to develop an “AI for Energy” blueprint that can help with site selection, power-flow modeling, permitting, generation optimization, asset monitoring, and security.

That creates an interesting loop: AI is helping drive electricity demand, while AI tools are also being deployed to help manage the infrastructure supplying that electricity.

Why This Matters Beyond Google

Google is not the only technology company looking for massive new power supplies.

As AI infrastructure expands, access to electricity is becoming one of the biggest constraints on how quickly data centers can grow.

The bottleneck is no longer only GPUs, networking hardware, or construction.

A company can acquire servers and land but still struggle to expand if the local grid cannot deliver enough power.

That is why technology companies are increasingly signing long-term agreements involving nuclear, renewable energy, batteries, and other forms of generation.

Does This Affect Philippine Users?

Not directly.

The agreement covers power infrastructure in the United States and the PJM grid.

But the broader trend matters globally because the cost of electricity and infrastructure eventually influences the economics of cloud computing and AI services.

For markets such as the Philippines, it also shows how important reliable generation and grid capacity could become if the country wants to attract larger data-center and AI infrastructure investments.

The Bottom Line

Google and Constellation have signed agreements covering 3,590MW of power, including 890MW of new nuclear capacity and a separate 2,700MW supply deal.

The project represents more than $4.3 billion in planned Constellation investment and shows how aggressively technology companies are securing energy for future computing growth.

AI's infrastructure race is increasingly becoming an electricity race too.
