Corscale’s Northern Virginia project is no longer just a proposed 300-plus-MW campus. The company now describes Gainesville Crossing in Prince William County as a five-building, 326-MW development. Corscale said its first building was completed in May 2024; later buildings were reported as fully leased, and a June 2026 financing deal covered one newly constructed, fully leased facility—not the entire campus.
What Corscale announced in 2022
On February 22, 2022, Corscale and USAA Real Estate announced that they had broken ground on the first building of a data-center campus in Gainesville, Virginia. The original plan called for a 130-acre site with more than 2.3 million square feet across five two-story buildings. Corscale described the campus as 300-plus MW and also cited 306 MW of utility power.
The first phase was planned as a 72-MW, approximately 483,000-square-foot building with eight data halls and office space. At the time, the company expected initial delivery in the fourth quarter of 2022. That was a forecast, not the eventual completion date: Corscale later said the first building was completed in May 2024. Corscale’s original announcement
Where Gainesville Crossing is—and is not
The campus, now called Gainesville Crossing, is in Gainesville, in Prince William County. “Northern Virginia” describes the broader data-center market; it does not mean the site is in Loudoun County. Corscale’s separately discussed Kincora project is in Loudoun County and should not be confused with Gainesville Crossing. Data Center Knowledge’s 2022 report

Why the headline capacity changed
The 300-MW figure was a rounded description of the original plan. Corscale’s 2022 announcement also cited 306 MW of utility power; its 2024 and 2025 updates describe a 326-MW campus at full buildout. Those figures track how the project has been described over time, but they should not be read as proof that 326 MW is energized, available to lease, or already serving customers.
| When | Published capacity description |
|---|---|
| February 2022, Corscale announcement | 300+ MW; also cited 306 MW of utility power |
| February 2022, Data Center Knowledge | More than 300 MW |
| July 2024, Corscale update | 326 MW at full buildout |
| January 2025, Corscale update | 326 MW at full buildout |
The later company figure refers to the planned full campus, not a verified operating-capacity measure. Data-center capacity can refer to utility supply, facility capacity, critical IT load, contracted space, or capacity already energized; the cited updates do not establish which portions of the full 326 MW are currently operational.

Construction and leasing milestones
- February 2022: Ground was broken on the first building, planned at 72 MW. The original target for initial delivery was Q4 2022.
- May 2024: Corscale said the first building had been completed.
- July 2024: Construction began on the second building, a 72-MW facility that Corscale said was fully leased to an undisclosed hyperscale tenant. The company expected completion in mid-2025 when it announced the project.
- January 2025: Corscale announced construction of a third building, a 54-MW facility it said was fully leased to an undisclosed client.
- June 2026: A Corscale–Affinius Capital joint venture secured $975 million to recapitalize Project Helios, described as a newly constructed, fully leased data center within Gainesville Crossing.
The public updates cited here do not establish the construction, lease, or operating status of the fourth and fifth buildings. Nor does “fully leased” by itself mean a building is commissioned, energized, network-ready, or occupied: those are distinct delivery milestones.

Who is developing the campus
Corscale was established as Patrinely Group’s data-center platform. The original 2022 announcement named USAA Real Estate as capital partner. Later Corscale materials describe the company as an affiliate of Patrinely and Affinius Capital. The change in branding across announcements is not enough to establish a complete account of current corporate ownership or the relationship between every project entity.

Who the campus is intended to serve
The project is aimed at hyperscale cloud providers and large enterprise customers that need substantial power and data-hall capacity, rather than ordinary small-business or consumer cloud users. Data Center Knowledge’s 2022 coverage described CorFlex modular data halls starting at 1 MW and CorBuild leases for an entire 36-MW building. Those were offerings reported at the time; the cited material does not confirm current commercial terms or availability.
Corscale said the second and third buildings were fully leased, but did not publicly identify the customers in the cited announcements. Project Helios was also described as fully leased. The tenant identities should therefore be treated as undisclosed, not inferred from the campus size or location.

The original project design included an on-site substation operated by Dominion Energy. The 2022 coverage also described possible energy-tariff choices, including renewable options. A tariff option is not the same as evidence that the campus runs entirely on renewable energy.

Corscale has described closed-loop cooling, water conservation, energy tracking, and ultra-low power-usage-effectiveness goals. It also announced a carbon-accounting partnership with nZero and plans to use ZincFive nickel-zinc battery technology.

- 📎 Rugged & Durable: The structure and finish of the server cabinet are built to perfection. The lock-in electronics/data cabinet is constructed of SPCC cold-rolled steel with a black powder coat finish that makes the 6U cabinet resistant to scratches and rust.
- 📎 Efficient Storage: Wall-mounted server cabinet is a must-have for anyone who needs to manage servers efficiently. The removable top panel allows for cable management, the removable and lockable side panels make it easy to organize your cables and protect your equipment.
- 📎 Ventilation Design: There are ventilation holes on the top and front door of the 6U server cabinet, and mesh design on the sides to increase airflow and prevent equipment from overheating.
- 📎 Space Saving: Wall-mounted/ floor-mounted dual-purpose network cabinet with compact design to maximize available space.
- 📎 Adjustable Rails: Adjustable mounting rails and square rack holes for easy equipment installation, suitable for 10-inch routers, switches, and AV/video equipment, etc.

What the 2026 financing does—and does not—show
The $975 million transaction reported in June 2026 was a recapitalization of Project Helios by a Corscale Data Centers and Affinius Capital joint venture, with financing from Blue Owl. The report described Helios as newly constructed, fully leased, and part of Gainesville Crossing. It is evidence of a significant financing milestone for that asset; it is not evidence that $975 million was the cost of the whole campus or that all five buildings are complete and operational.
What customers, investors, and local stakeholders should watch
- Delivered capacity: Distinguish the 326-MW full-buildout figure from power that is energized and available to customers.
- Remaining buildout: Public updates cited here do not resolve the status of buildings four and five.
- Customer concentration: The second and third buildings were reported fully leased, but their tenants were not named in the cited announcements.
- Power and interconnection: Grid availability, connection timing, and tariff structure affect when planned capacity can serve customers and at what cost.
- Cooling and water performance: Company design claims matter, but measured operating results are not included in the cited materials.
- Local delivery conditions: Construction timing, equipment availability, permitting, and community concerns can influence development schedules.
For a prospective customer, the campus-wide MW figure is not an inventory list. Current availability, delivery dates, lease terms, power configuration, and network readiness require direct confirmation from Corscale.
