Summary

Constellation Energy Signs Google

Constellation Energy signed a 20-year, 3.59 GW power purchase agreement with Google.
The agreement guarantees at least 890 MW from Constellation’s nuclear fleet and adds 2.7 GW from the PJM market.
Google will fund $4.3 billion of reactor upgrades in Illinois, Pennsylvania and New Jersey.
Constellation’s shares rose about 12%-15% to roughly $300.
Analysts warn that required reactor uprates pose execution risk that could pressure the stock.

Summary

Google Launches AI Alliance

Google’s 2030 net-zero pledge sits alongside an 81 % emissions rise since the 2019 baseline, driven by AI.
The agreement adds carbon-free baseload nuclear power, which policymakers cite as key to meeting U.S. climate targets.
Google, Constellation and Emerald AI formed the AI Energy Management Alliance to free up 100 GW of data-center capacity via demand-response.

History

Historical Context

Google’s 2009 20-year wind PPA with NextEra, securing 1.2 GW for $2.6 billion, built on earlier corporate renewable moves—by 2007 Google already piloted solar and invested in wind projects, and NextEra, founded in 1925 and rebranded that year, had become the world’s largest wind operator. The deal foreshadowed today’s >22 GW of Google clean-energy contracts.
