Companies and organizations
| Name | Role | Notes | Sources |
|---|---|---|---|
| EdgeConneX | Developer | The August 2026 report (which spells it EdgeConnex) says the company developed the campus; it does not say who owns it. | The Atlanta Journal-Constitution |
| Microsoft | Tenant | Described in August 2026 as leasing space at the campus, which it does not own. The July 2024 report (s1) instead described three buildings that Microsoft would own and operate. | The Atlanta Journal-Constitution |
| Microsoft | Developer | Role as reported in July 2024, when a Microsoft executive said the company had purchased additional Fulton County property to support data center construction already under way. Later reporting (s3) describes the campus as EdgeConneX-developed and leased. | Southern Business & Development (via Atlanta Business Chronicle) |
| Development Authority of Fulton County (Develop Fulton) | Government | Was scheduled to discuss the USD 75 million ten-year tax abatement in July 2024. The 2026 report says the break was ultimately granted by Union City's development authority after Develop Fulton first considered it. | Southern Business & Development (via Atlanta Business Chronicle); The Atlanta Journal-Constitution |
Timeline
| Date | Event | Actual or planned | Notes | Sources |
|---|---|---|---|---|
| 2024-07 | Other | Actual | Microsoft was confirmed, per the Atlanta Business Chronicle as relayed by Southern Business & Development, as the company seeking a USD 75 million, ten-year property tax abatement from the Development Authority of Fulton County. | Southern Business & Development (via Atlanta Business Chronicle) |
| 2024-07 | Other | Actual | A Development of Regional Impact filing describing the roughly 2.1 million sq ft campus was made public. | Southern Business & Development (via The Atlanta Journal-Constitution) |
| 2026-08 | Other | Actual | When Microsoft moved to unwind tax incentives for its own metro Atlanta projects in East Point, Palmetto and Douglasville, tax breaks tied to leased facilities such as the Union City campus were reported as unaffected. | The Atlanta Journal-Constitution |
No megawatt figure was found in the sources that could be opened. Ownership is described differently over time: in July 2024 the buildings were to be Microsoft owned and operated (s1), while in August 2026 the campus is EdgeConneX-developed with Microsoft leasing space (s3); each framing is kept with its own source and date. The July 2024 report put site development costs at about USD 43.5 million. The July 2024 regional-impact report said Microsoft had paid at least USD 171 million that year for more than 480 acres on Atlanta's Southside, including the Union City site; that is a multi-site figure, not a campus figure.

Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
