Research note
Research note: Google signs 3.6 GW power deal with Constellation, including 890 MW of new nuclear capacity
How we checked the size, terms and timing of the Google–Constellation agreements against Constellation’s release and two trade outlets.
What we set out to check
The size of each agreement, how long each lasts, how much is new capacity, when it arrives, and what remains undisclosed.
What we found
- Constellation’s release confirms 890 MW over 20 years, more than $4.3 billion of investment, 11 units at six sites, and the first uprate by 2028.
- It also confirms the separate 15-year agreement for 2,700 MW from existing plants.
Numbers that differ
Some coverage calls the whole 3.6 GW “nuclear”. The release separates 890 MW of new nuclear capacity from 2,700 MW of supply from the existing fleet, and we follow the release.
Labels we chose and why
- Confirmed for terms in the release.
- Unconfirmed for the end-2032 completion date, which we found only in POWER Magazine.
What we could not verify
- The contract price.
- Which plants get which share of the 890 MW.
What we searched
- Google Constellation 3.6 GW nuclear agreement uprates
- Constellation Google 890 MW press release
- Constellation uprates NRC applications 2026 2030
