Google and Constellation Expand Nuclear Capacity with $4.3 Billion Deal

Google and Constellation Energy have struck a landmark agreement to add 890 megawatts of new nuclear capacity to the PJM Interconnection grid. The 20-year power purchase agreement will fund upgrades at 11 Constellation-owned nuclear units across Illinois, Pennsylvania, and New Jersey, boosting thermal and electrical efficiency. This capacity is entirely new, expanding total electricity generation available across the PJM footprint. The deal is expected to sustain roughly 4,400 existing jobs and create approximately 7,200 new construction jobs during the building period, representing more than $4.3 billion of new investment by Constellation.

In addition to expanding nuclear generation, the companies have entered into a 15-year energy supply agreement for an additional 2,700 MWs in PJM's fleet. This financial structure ensures that Constellation's operating generation assets continue to deliver energy and capacity to the PJM market. Constellation also selected Google Cloud and Gemini Enterprise under an expanded five-year technology alliance to establish an 'AI for energy' blueprint that will accelerate capacity delivery, optimize asset dispatch, and protect critical infrastructure.

According to Google's global head of energy and power, Amanda Peterson Corio, the agreement will strengthen the PJM grid, which serves 67 million people, while protecting energy affordability and supporting local union jobs. Constellation's chairman, president, and CEO, Joe Dominguez, highlighted the importance of preserving and expanding the output of the existing nuclear fleet to meet the nation's growing energy needs while keeping costs affordable for homes and businesses.

The agreement offers a direct response to PJM's 'Bring Your Own Power' proposal, providing a practical model for how major power consumers can expand new supply alongside growing operational requirements, without state or federal mandates. Key elements of the commercial agreement include direct supply expansion, revenue certainty, demand flexibility integration, and economic and community investment.
