What the source record says
Two single-story facilities (SAT89 and SAT90), each 244,700 sq ft, along US Hwy 90 in Medina County. Part of Microsoft's broader San Antonio campus (operating since 2005). $765M investment covers the two new buildings; broader expansion including Texas Research Park adds another $1B. Coordinates are approximate Castroville area centroid; exact parcel not publicly identified. Completion target corrected to July 2027 per permit filings. Tax abatements for SAT89/SAT90 are shielded under Texas competitive-information law (a Chapter 312 abatement is confirmed only for the earlier SAT82 building); site-specific job counts are unpublished (an earlier SAT82 building cited ~50 permanent / ~1,500 construction).
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
