U.S. Data‑Center Construction Digest – Dec 8–12, 2025
The digest below compiles major U.S. data‑center construction news from the past seven days (8 Dec – 12 Dec 2025). Items are sorted in reverse chronological order and include project status (under development/under construction vs. still in planning). Each entry lists the developer or proposer, project location and scale (megawatt capacity, square footage and acres when available), investment figures, timetable and noteworthy partners or contractors.

| Copia Power (backed by Carlyle Group) | Lyon County, Nevada: two‑parcel site totaling 505 acres at 150/155 Penrose Lane; plan includes north and south campuses, battery‑storage system, natural‑gas backup system and on‑site substation. | Phase 1: ~150 MW across 2–4 buildings; full build‑out could see up to 500 MW via natural‑gas systems. Developer expects construction to complete in 2–3 years, but overall timeline depends on regional utility projects (5–10 years). | Planning – rezoning approved. Further approvals required before construction; end user not yet disclosed. | Citizens voiced environmental concerns about the project. Copia Power, a green‑energy firm, will rely on NV Energy’s Walker River substation and Greenlink transmission projects. |
| CyrusOne (KKR‑owned) | Whitney, Bosque County, Texas: campus adjacent to Calpine’s Thad Hill gas plant. Existing site under development; new filings cover three single‑story data centers: DFW17 (88,875 sq ft), DFW17B (249,090 sq ft) and DFW17C (93,320 sq ft). | DFW17: $375M, construction Oct 2025–Dec 2026. DFW17B: $500M, construction Jan 2026–Apr 2027. DFW17C: $430M, construction Feb 2026–Apr 2027. Earlier buildings DFW10 and DFW11 (250k sq ft and 88,875 sq ft) are also underway. The campus could reach ~400 MW when fully built. | Under development / under construction. Filings indicate ongoing expansion. | The campus leverages a natural‑gas plant for power and sits between Dallas–Fort Worth and Waco. CyrusOne has >50 data centers and >14 in Texas. |
| Beale Infrastructure (Blue Owl‑owned) | Pima County, Arizona: Project Blue, a planned 290‑acre AI data‑center campus with up to ten buildings totaling 2 million sq ft and ~600 MW capacity. | Local officials switched from reclaimed‑water cooling to air cooling; Amazon Web Services (AWS) – long assumed to be the end user – withdrew interest. Other potential tenants (e.g., Meta) are being considered. Construction timeline not disclosed. | Planning. Rezoning and site preparation continue; campus seeks new anchor tenant after AWS exit. | Illustrates growing tension over water use in desert regions. The campus would include renewable power and battery storage, but details are being re‑worked. |
| Solis Arx (newly formed developer) | Progress Park, Wythe County, Virginia: planned on a 99‑acre site; first data center for the countycardinalnews.org. | Exact building size, power capacity and construction timeline still being finalizedcardinalnews.org. Developer aims to create a technology campus supporting advanced computing and local job growthcardinalnews.org. | Planning. Rezoning and permitting are in early stages. | Progress Park offers robust electrical infrastructure via Appalachian Power and abundant water supplycardinalnews.org. Solis Arx intends to own and operate the campus and lease capacity to tenantscardinalnews.org. |
| PBA Holdings & WPB Logistics Owner LLC (owners of Palm Beach Aggregates) | Palm Beach County, Florida: 202‑acre site at 20‑Mile Bend near Florida Power & Light’s 3,750 MW West County Energy Centerstetnews.org. Zoning Commission approved plans for nearly 1.8 million sq ft of data‑storage buildingsstetnews.org. | The proposal, dubbed Project Tango, aims to build a hyperscale data‑storage campus; power needs not publicly disclosed. The developer has a binding power‑service agreement with FPL and must conduct noise studies before constructionstetnews.org. Final approval will go before the county commission within a weekstetnews.org. | Planning. Zoning approved; final county commission hearing pending. | The center is adjacent to residential community Arden; residents raised concerns about noise, water and environmental impactsstetnews.org. State law allows the end user to remain confidential (“Project Tango”)stetnews.org. |
| Deep Atomic & consortium (Parker Tide, Clayco, Gleeds, Paragon Energy, EvapCo Dry Cooling, Bedrock Labs, Azimuth Renewables, Future‑Tech, Moonlite AI) | Idaho National Laboratory, Idaho Falls, Idaho: concept uses the MK60 small modular reactor, delivering 60 MW of electricity and 60 MW of integrated cooling. Campus would include AI hardware, carbon‑free energy and closed‑loop cooling. | The consortium aims to start operations within 24–36 months by running on grid, geothermal and solar power while the SMR completes regulatory certification. Proposal can scale by adding modules; would serve as a national demonstration site for nuclear‑powered AI infrastructure. | Planning. Proposal submitted to US Department of Energy; no construction yet. | The project intends to showcase integrated power and cooling, with future phases adding additional reactor modules and data‑center blocks. |
| CleanArc Data Centers (Arlington, TX) | Caroline County, Virginia: 900 MW hyperscale campus on a 612‑acre site (VA1)constructiondive.com. | $3 billion investment. Campus delivers 900 MW in three phases: 300 MW by 2027, another 300 MW by 2030, and final 300 MW between 2033–35constructiondive.com. Uses closed‑loop cooling and modular, pre‑engineered components to minimize water consumption and speed deploymentconstructiondive.com. | Under development / under construction. Groundbreaking occurred early Dec 2025. | Virginia Governor Glenn Youngkin called it the largest economic investment in Caroline County’s historyconstructiondive.com. |
| Applied Digital Corporation | Ellendale, North Dakota: Polaris Forge 1 AI Factory Campus; Building 1 is a 100 MW facility comprising two 50 MW phases. Campus will deliver 400 MW IT load at full build‑out. | Construction began in Sept 2022; the second 50 MW phase of Building 1 came online in December 2025. Capacity is contracted to CoreWeave under a 15‑year, $11 billion agreement that was expanded from 250 MW to 400 MW. | Under development / under construction. Additional buildings are planned. | Applied Digital (formerly Applied Blockchain) still operates cryptomining facilities but is pivoting to AI and HPC. The site has more than 1 GW of power under load study. |
Key Trends and Observations
- Large‑scale campuses face regulatory hurdles. Several projects—Monarch (Nevada), Solis Arx’s Wythe County campus, Project Tango in Florida and Project Blue in Arizona—are still navigating zoning, environmental reviews or shifts in cooling strategies. Community concerns about water use, noise and land impact frequently surface,
- Expansions continue in established markets. CyrusOne’s Whitney campus expansion demonstrates how existing operators are layering multiple buildings to meet hyperscale demand; the campus could reach 400 MW. Applied Digital’s North Dakota campus delivered its first 100 MW building and is scaling toward 400 MW.
- Innovative power approaches emerge. The Deep Atomic proposal pairs small modular reactors with data‑center cooling and aims to use the site as a national demonstration. CleanArc’s VA1 campus relies on closed‑loop cooling and modular components to reduce water and accelerate deployment.
- Mega‑project momentum remains strong. While some projects like Project Blue face uncertainty, multiple billion‑dollar developments—Monarch, CleanArc’s VA1, and the Palm Beach Project Tango—illustrate the ongoing push to build massive AI‑ready campuses across the U.S., even as power and community constraints tighten.
