Google enters massive 3.6-GW power deal with Constellation Energy

Key Points:

• Google has signed a 20-year power purchase agreement with Constellation Energy for 3,590 megawatts of electricity in the PJM Interconnection grid, with about 25% coming from upgraded nuclear plants.
• The deal will support over $4.3 billion in new investments by Constellation to enhance capacity at several nuclear reactors in the Midwest and Mid-Atlantic regions, with the first upgraded plant expected to deliver power by 2028.
• Google’s agreement includes 890 megawatts from nuclear plants and an additional 2,700 megawatts from Constellation's broader generation portfolio, providing long-term revenue certainty for Constellation’s operating plants.
• This arrangement is part of a broader trend where major tech companies secure large-scale electricity supplies to power data centers and respond to PJM's proposal requiring data centers to bring their own power or risk disconnection during peak demand.
• Constellation, the largest US nuclear power operator, owns multiple nuclear and natural gas plants, and this deal reflects commitments to invest in clean, reliable energy to support grid growth responsibly.
