Atlanta.

The market right now

The growth is barbell-shaped: dense interconnection downtown around the 56 Marietta carrier hotel, and enormous grid-fed AI campuses to the south and west — Fayetteville, Palmetto, Douglas and Butts counties. Local politics are reshaping the map in real time; Fayetteville banned new data centers in March 2026 even as the buildings already permitted there keep rising.

• Second-largest US market by inventory behind Northern Virginia: 1,459 MW at end-2025, up 459 MW YoY (CBRE H2 2025)
• 2,076 MW under construction with vacancy near 2% (CBRE H2 2025)
• Record 918 MW absorbed in just the first six months of 2026 (JLL H1 2026)
• More than 3 GW of long-term utility power commitments support the pipeline (CBRE H2 2025)
• Named one of North America's fastest-growing data center hubs (CBRE 2025)

• Microsoft's Fairwater Atlanta runs grid-only at gigawatt scale, leaning on Georgia Power reliability (Measured AI 2026)

The regulatory picture

Enforcement. Federal OSHA jurisdiction (no private-sector state plan); Atlanta-area offices; national emphasis programs incl. heat illness apply to construction

Licensing. Statewide electrical contractor licensing (Class I/II) via Georgia's State Construction Industry Licensing Board; no state journeyman card — worker qualification set by employers/localities

Also in play. Fayetteville banned new data centers citywide March 2026; Atlanta prohibits them near BeltLine and MARTA stations since Sept 2024 (Atlanta Tech News)

What it means for the work

The safety exposure in this market concentrates at the energization boundary: thousands of construction electricians transitioning from OSHA 1926 rules into an operating facility's NFPA 70E program, building by building, for the next several years.

Fastest-scaling US market — 2 GW under construction means huge commissioning and energization workloads with contractor crews new to data centers

Gigawatt-scale grid-only AI campuses (Fairwater) concentrate medium-voltage switching and load-bank testing at record density

Federal OSHA jurisdiction with heat-illness emphasis for Georgia summer construction

Local moratoria (Fayetteville ban, Atlanta BeltLine/MARTA limits) push new builds to exurban counties with less inspection infrastructure
