Gigawatt-Scale AI Datacenter Site Inventory

Comprehensive catalog of named AI datacenter campuses publicly announced or under construction at ≥500 MW IT load or ≥1 GW total. Last refreshed May 2026.

This wiki tracks the physical buildout behind the AI capex boom. The gap between "announced" and "energized" is the single most important variable on this page: a 5 GW campus that won't reach full power until 2030 is a different financial object than a 500 MW campus energizing in 2026. Where possible, we distinguish phased capacity from headline capacity.

Microsoft

Microsoft's "Fairwater" reference design — two-story, closed-loop liquid cooling, no UPS or genset in some sites — is being deployed at five-plus sites linked via dedicated AI WAN ("AI superfactory").

Sources Utility Dive, Talen IR, DCD, The Register

Other AWS notable sites

  • Northern Virginia (Loudoun) — AWS operates dozens of Loudoun facilities; county-wide hyperscaler load now exceeds 5 GW (across all operators), with AWS holding the plurality. Dominion's interconnect queue is multi-year.
  • Mississippi (Madison County) — AWS announced $10B campus November 2024 targeting 1 GW.
  • Indiana, Ohio, North Carolina — additional AWS clusters under planning, not all gigawatt-scale.

Google

Google's hyperscale buildout predates the AI boom; AI-driven expansion is grafted on top of legacy regions.

Site Location Capacity Status Notes
Council Bluffs Council Bluffs, IA ~1 GW estimated across Southlands campus (4 bldgs, 2.9M sq ft) Operational + expanding $7B pledged 2024; first DC announced 2007

Apple does not publish per-site GW figures, but the $500B Feb 2025 commitment over four years implies substantial expansion at each. [Sources: AZ Tech Council, Data Center Knowledge, MIT Tech Review]


Anthropic

Anthropic does not directly operate datacenters; its capacity flows through AWS (Project Rainier, primary) and Google Cloud (TPU clusters in Council Bluffs and elsewhere). The Project Rainier site (above) is effectively Anthropic's anchor. Future Anthropic compute will likely include additional AWS regions and a rumored Google Cloud-dedicated cluster.


Colocation / Wholesale Operators

Digital Realty (DLR)

5 GW of buildable IT capacity worldwide as of Q3 2025. Notable gigawatt-class buildable inventory:

  • Manassas, VA — multiple 100+ MW IT-load facilities; large hyperscale bookings in 2024–2025
  • Dallas (Digital Dallas) — 400–450 MW total at full buildout
  • Hillsboro, OR — recent 30-acre acquisition adds 160 MW IT capacity to an existing 85 MW assemblage
  • Loudoun (Ashburn) — DLR's flagship cluster; integral to Northern Virginia's >5 GW load
  • U.S. Hyperscale Fund — Final close $3.25B in March 2026 funds incremental gigawatt-class buildouts

Cross-cutting Observations

Announced vs energized gap. Several headline capacities (Hyperion 2–5 GW, Shackelford 5.5 GW, Mt. Pleasant 3.3 GW) reflect 2028–2030 buildouts. As of mid-2026, energized AI-specific load at the largest sites is closer to: Abilene ~200 MW, Rainier ~1 GW, Colossus ~1.5 GW, Mt. Pleasant ~500 MW, Atlanta Fairwater ~500 MW. The narrative "10 GW of Stargate" is roughly 7 GW announced and <500 MW energized.

Construction partner concentration. DPR Construction, Turner Construction, and Mortenson dominate Big Tech datacenter contracts; they jointly anchor Hyperion and individually anchor Abilene (DPR), Mt. Pleasant Phase 1 (Walsh), and several Meta builds (Mortenson). Holder and Clayco have major Meta/Microsoft work in the Southeast.

Power source split. Roughly: AWS Susquehanna is the only fully nuclear-anchored hyperscale today (with Microsoft's Three Mile Island restart agreement and several SMR LOIs pending). Meta Hyperion locks in three new gas plants in Louisiana. xAI Colossus is the most aggressive BTM gas deployment. Stargate Abilene blends ERCOT grid + Lancium-controlled BTM gas. Stargate UAE will blend Barakah nuclear with gas.

Litigation hot spots. Prince William Digital Gateway (canceled), xAI Colossus permitting (active SELC/NAACP/Earthjustice litigation), Newton County water (community pressure), Tucson and Reno water (Apple permitting friction), Louisiana ratepayer protections for Entergy gas plants.

Tax abatement. Most state-level deals offer >20-year property tax abatements (Louisiana, Indiana, Wisconsin, Mississippi) plus sales-tax holidays on servers; per-job subsidy economics are weak when annualized — a recurring critique in local journalism (Memphis Commercial Appeal, NOLA.com, Indiana Public Media, WPR).
