Google Signs 890 MW Nuclear Energy Agreement With Constellation Energy

Google has partnered with Constellation Energy in a 20-year power purchase agreement. This deal adds 890 megawatts of nuclear capacity to the PJM grid, reflecting the technology sector's use of atomic energy to fuel artificial intelligence data centers. Google is also pursuing early-stage development projects to build nuclear infrastructure.

This initiative addresses an electricity shortfall caused by power-intensive AI training and inference workloads. As major cloud providers strain regional electrical grids, technology companies are turning to carbon-free nuclear generators for reliable baseload power.

Scale of the Constellation Energy Partnership

The 20-year agreement between Google and Constellation Energy will fund over $4.3 billion in infrastructure upgrades across 11 existing nuclear units in Illinois, Pennsylvania, and New Jersey. These modernizations aim to increase generation output and extend the operating lives of the plants.

Constellation entered a separate 15-year agreement to supply an additional 2,700 megawatts to the PJM Interconnection market. Constellation also expanded its technology partnership with Google Cloud and Gemini Enterprise, using artificial intelligence tools to optimize power plant generation and operational efficiency.

Prospective Development With Elementl Power

Google is providing early-stage capital to Elementl Power to explore the development of three potential advanced nuclear sites. Each location targets at least 600 megawatts of generation capacity.

These Elementl Power projects remain in early-stage development. They depend on future regulatory approvals, site evaluations, and construction milestones before delivering power to the grid.

What Is at Stake for the PJM Grid

The PJM Interconnection manages the high-voltage electrical grid across 13 states and the District of Columbia, serving over 65 million people. The influx of new nuclear capacity backed by corporate purchase agreements shows how technology firms are subsidizing regional grid stability to secure electricity for data center campuses.
