Overview
- Google and Constellation announced the package Tuesday, committing to about 3,590 megawatts of supply that includes a 20‑year PPA to underwrite 890 MW of uprates and a separate 15‑year agreement for roughly 2,700 MW.
- Constellation will invest more than $4.3 billion to upgrade 11 reactors at six plants in Illinois, Pennsylvania and New Jersey with the first incremental power expected in 2028 and full delivery targeted by 2032.
- Google says it will cover the costs of the uprates and related transmission work so that the companies argue other ratepayers will not bear the expense.
- The deal includes a five‑year technology collaboration using Google Cloud and Gemini Enterprise to help plan uprates, speed permitting and construction, and optimize plant output.
- Markets reacted quickly with a sharp rise in Constellation shares, and the agreement now moves to regulatory filings, PJM and FERC review, and local permitting amid job gains and ongoing safety and oversight questions.
