Google Backs Constellation Nuclear Upgrades Targeting 890 MW by 2032

Google is backing enough upgrades to add 890 megawatts of nuclear power, but that electricity is still a future commitment. Its October 6, 2026 agreement with Constellation Energy targets delivery before the end of 2032. Driven by Google’s data-center growth, the collaboration combines financing for existing reactors with an AI deployment inside the power producer’s operations.

The work covers 11 reactors at six operating plants in Illinois, Pennsylvania and New Jersey. Their additional output is intended for PJM, the regional electricity grid spanning 13 states in the Mid-Atlantic and Midwest and serving 67 million people.

A customer commitment pays for higher output

Rather than build a new plant, Constellation will increase output from reactors already running. These projects, called nuclear uprates, modernize equipment such as turbines, steam generators and digital control systems. Google describes the combined increase as roughly equivalent to adding one large reactor to the electricity system.

Google is financing physical and digital upgrades and acting as the projects’ anchor customer through a power purchase agreement. Its long-term commitment to buy electricity gives Constellation revenue certainty to invest in the work, Google says.

Google says other grid customers will bear none of the associated upgrade costs. It also argues that improving existing plants will deliver capacity years faster than building a reactor from scratch, with significant savings for the electricity system.

More than 1.5 GWCapacity enabled through uprates and restarts

Google says this agreement brings its total nuclear capacity enabled through uprates and restarts above 1.5 gigawatts.

Gemini joins the plant-upgrade work

The collaboration also puts Google Cloud’s Gemini Enterprise into Constellation’s core operations. Google says AI-driven workflows will help accelerate upgrade planning, streamline construction and optimize plant output. The software deployment links Google’s role as a power customer with its role as a technology supplier.

Employment estimates, but no confirmed deal value

Google projects that the work will sustain roughly 4,400 existing jobs and support approximately 7,200 construction jobs. Those are company employment estimates, not a count of new permanent positions already created.

The financial size remains unconfirmed. Interesting Engineering’s October 6 article reported a potential value of at least $1 billion, citing sources familiar with the matter. Google’s announcement does not disclose a dollar amount.
