Google Storey County is an operational AI data center hosting an estimated 154k H100-equivalent chips, scaling toward a projected 652k H100-equivalent chips — supported by 161 MW of IT power, rising to 300 MW — at a capital cost of $6.1 B, rising to $11.4 B. We estimate that it uses Google TPU v5e and Google TPU v6e chips. The timeline of IT power and compute capacity is based on satellite imagery, our cooling equipment power model, chip availability, and chip efficiency. Storey County is one of Google’s rare dry-cooled campuses, likely an adaptation to water-scarce Nevada.
