Aterio’s Report on US Data Center developments, June, 2025
In May, satellite imagery analyzed by Aterio provided critical visibility into the actual progress and delays across major U.S. data center campuses. While many projects continue on schedule or ahead of pace, others are showing signs of strategic pause or reassessment

How far away are we from a 1 GW Data Center?
The quest for a 1-gigawatt (1GW) data center—the pinnacle of computational power—is not just a technical challenge but also an economic and logistical undertaking. While data centers are growing rapidly, achieving 1GW capacity introduces unique challenges in infrastructure, power, and technology.

About our nuclear coverage
Aterio follows the return of nuclear power in the United States: restarts of retired plants, uprates at operating sites, new large reactors and the small modular reactor pipeline.
Our coverage focuses on what separates an announcement from a delivered megawatt, the licensing path, the offtake agreement, the supply chain and the site itself. Much of this demand traces back to hyperscale computing, so we track the contracts that tie reactors to data center load and what they imply for the grid around them.
