Microsoft SAT15 Data Center — 3555 Westover Link

Microsoft SAT15 is a distinct project at 3555 Westover Link in San Antonio. TYPE3’s map data names Microsoft San Antonio (SAT15), marks it announced, and records zero MW. TDLR Project TABS2022026535 identifies SAT15 Data Center at the address, with Microsoft as owner, a 245,000-square-foot shell and fit-out, and an estimated October 2022 to May 2026 timeline. A later TDLR record identifies a separate SAT17 project at the same address with another 245,000-square-foot scope and a later estimated timeline. One frozen reference identifies SAT17 as TABS2024001197, while the cited TDLR project URL <https://www.tdlr.texas.gov/TABS/Projects/TABS2025001197> uses a different identifier; the conflict is unresolved.

The filings establish two same-address project records, not one combined building or capacity figure. Neither cited filing provides site MW. TYPE3’s map data records zero MW, and the estimated completion dates do not prove energization, current operation, or service availability. Nearby Microsoft Chevron and SN7 records have different addresses and remain separate.

SAT15 therefore has a precise project identity and filed scope, while current status and load remain unresolved. The SAT15 code, 3555 Westover Link address, and relationship to the separate SAT17 project distinguish it from nearby Microsoft facilities. No source in this record confirms spare Microsoft capacity or retail colocation.
