AWS Acquired Nuclear-Powered Data Center for $650M
Talen Energy will supply the Pennsylvania-based AWS data center with carbon-free nuclear power.

Big Idea:
AWS has acquired Talen Energy's Cumulus Data data center campus in Pennsylvania for $650 million, which is located at a nuclear power station and includes all the land, power infrastructure, and intangibles.
State of Play:
AWS plans to develop up to a 960MW data center campus in northeast Pennsylvania, with two 10-year extension options tied to nuclear license renewals and minimum contractual power commitments that ramp up in 120 MW increments.
Why It Matters:
Talen Energy will supply AWS with direct-connect, carbon-free power for the data center campus, and under a separate agreement, Talen will also receive additional revenue from AWS related to sales of carbon-free energy to the grid.
Key Details:
- AWS acquired the Cumulus data center campus for $650 million, planning to develop a 960MW facility.
- The campus is powered by the 2.5GW Susquehanna Steam Electric Station, one of the largest nuclear power plants in the US.
Flashback:
Talen Energy, founded in 2015, established Cumulus Growth in 2020, comprising Cumulus Data for hyperscale data centers and Cumulus Coin for digital currency mining.
What's Next:
There are numerous synergies between datacenter infrastructure and cryptocurrency mining sites, so similar acquisitions are likely to occur in the future.
The Bottom Line:
AWS's acquisition of a nuclear-powered data center campus underscores the tech industry's shift towards sustainable energy solutions, with significant implications for the future of data center operations and green energy adoption.
Yes, but:
While nuclear power offers a carbon-free energy source, concerns about nuclear waste and safety remain, highlighting the need for continued innovation in sustainable energy technologies.
