Under construction
United States · 1 project · Last reported
Summary
Related Digital is building The Barn, a 250-acre campus of three single-story buildings in Saline Township, Michigan, exclusively for Oracle, serving OpenAI under the Oracle-OpenAI Stargate expansion. Announced in October 2025 at more than 1 GW, it is described in later coverage as 1.4 GW. DTE Energy is to supply all power, alongside new battery storage paid for by the project. State regulators approved DTE's contracts for the campus in December 2025. In June 2026 the partners marked construction with all buildings under way and the first nearing completion. Walbridge is general contractor; financing mixes Related Digital and Blackstone-affiliated equity with PIMCO-anchored debt.

- The frozen global-open-v3 Polygon is a contributor-mapped construction-site locator for the named Barn data-center campus, inherited by the current-build project through the explicit v14 project_targets relationship. It is not an official, cadastral, or survey boundary; a verified complete 250-acre campus extent; a building or project footprint; a construction extent; or a source of lifecycle, capacity, energy, operating-status, or imagery claims.
- Horizontal uncertainty
Not reported
OpenStreetMap does not state horizontal positional accuracy; community-mapped geometry is not a cadastral or survey product.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
