Google signed a 20-year power purchase agreement with Constellation, supporting $4.3 billion in investment and 890 megawatts of nuclear expansion.

Utility Dive reports a signed power purchase agreement (PPA), rather than preliminary negotiations. Its headline associates the Google–Constellation transaction with $4.3 billion of investment and 890 megawatts of new nuclear capacity in the PJM Interconnection region.

The capacity figures must be kept separate from the broader contracting total. The article summary says Constellation signed 20-year PPAs with both Google and Amazon during the preceding week, together supporting almost 1.1 gigawatts of nuclear expansions; that combined figure is not attributable to Google alone.

The investment and new capacity are described as supported future additions, not already operating assets. A Telegram roundup separately cites 3,590 megawatts under a 20-year Google agreement and Gemini integration into energy operations, but it does not explain that larger figure’s existing-versus-new capacity breakdown.

The supplied coverage also records a substantial equity-market move. Financial_Express reports Constellation Energy shares closed up 12.25% on October 6, although the material contains no electricity price, project-by-project commissioning schedule, or contractual termination provisions.
