Microsoft SAT14

San Antonio, Texas, United States

Microsoft SAT14 is an operational AI data center hosting an estimated 45k H100-equivalent chips — supported by 47 MW of IT power — at a capital cost of $1.8 B. We estimate that it uses Nvidia H100 and Nvidia B300 chips. The timeline of IT power and compute capacity is based on satellite imagery, our cooling equipment power model, regulatory filings, chip availability, and chip efficiency.

Building 1 operational. The first 2 data halls of Building 1 (with chillers already installed) are likely to be already operational. Although construction was completed prior, the on-site substation was previously incomplete, so we believe it was only operational at this point.

No more visible construction around either building, just a little equipment. Roads fully built around buildings as well.
