Chantilly, Virginia, October 10, 2025
News Summary
Construction has begun on Chantilly Premier, a fully leased powered shell tied to regional fiber and power, while county planners approved two 300 MW electrical substations to support growing data center demand. One substation, Towerview, will sit on a 3.8-acre parcel near a major road and a data‑center campus; the other, Takeoff, will occupy about 10.2 acres with landscaping and a pond retention plan. A local Chantilly engineering and construction firm also launched a full lifecycle AI and HPC infrastructure suite. The moves underscore infrastructure growth, community concerns, and pending construction timelines.
Chantilly Premier powered shell breaks ground as Northern Virginia adds two 300‑MW substations; industry services expand

Lead
Construction has started on a new data‑center project in Chantilly after the developer secured financing for the site. The project is a 100% leased powered shell positioned in Northern Virginia where demand for data capacity and power infrastructure is growing rapidly. At the same time, county officials approved two new electrical substations rated at 300 megawatts each to support current and future data‑center development. A separate local company rolled out a suite of services designed to help build and run high‑density computing facilities.
Key developments at a glance
- Chantilly Premier — ground broken on or before Oct 10, 2025; construction financing confirmed; described as a 100% leased powered shell with direct access to local fiber and power networks.
- Two substations approved — Towerview and Takeoff, each planned for 300 MW, cleared through the county’s 2232 review process to ensure compatibility with regional planning.
- Industry services — a full lifecycle AI and HPC infrastructure offering launched earlier in 2025 to serve high‑density data operations.
Where Chantilly Premier fits
The Chantilly site sits in a well‑connected part of Northern Virginia, benefiting from dense fiber networks and robust power corridors. The project was presented as a powered shell designed to let tenants move in and deploy equipment quickly. The dateline for the construction notice was CHANTILLY, Va., Oct 10, 2025, and the release is copyrighted by the wire service that issued it.
Fairfax County approvals and infrastructure details
The county planning body approved two separate substation projects in votes that required the special 2232 review. The first, known as Towerview, is a 3.8‑acre parcel near Sully Road and Park Center Road east of Dulles International Airport. It is sited adjacent to a large data‑center campus under construction to the south and is intended to feed a nearby technology park and nearby homes and businesses. The second, named Takeoff, sits on a mostly undeveloped 10.2‑acre tract at Route 50 and Avion Parkway next to airport property and will help serve data centers across Avion Parkway.
Both substations are rated at 300 megawatts. Towerview will sit between 112 and 190 feet from the nearest property lines, with county noise rules requiring operating levels at or below 55 decibels at the property line. Takeoff will be set back about 100 feet from Route 50, ringed by a treescape buffer and a 12‑foot decorative wall, with an existing pond retained as part of site design.
Public comment at the planning meeting included resident concerns about safety, noise, pollution and water impacts, and requests for alternate siting. County commissioners asked utility officials to work with the surrounding communities during construction and operations. One commissioner recused from the votes due to prior employment with the utility; otherwise both projects were approved unanimously among participating commissioners.
Regional context: rapid build‑out and community impacts
Demand for data capacity has surged with growing use of artificial intelligence and cloud services. The region hosts several hundred data centers, with two specific local towns together accounting for roughly 260 sites. Regional facilities range from compact colocation rooms to campuses covering nearly one million square feet. This concentrated build‑out has produced frequent siting near parks, schools, homes and historic sites, prompting public debate over noise, lights, traffic, power draw and effects on local water supplies.
Data centers require large amounts of electricity and cooling water, and many installations have major rooftop fans and other mechanical systems that can produce noise. New substations and transmission lines are often needed to meet growing power demands, and the cost of those upgrades can factor into local electricity prices. The long history of regional build‑out began when major internet firms relocated to the area decades ago, which in turn attracted colo and hyperscale investment and an extensive fiber network.
Industry response and services for high‑density computing
A local infrastructure firm launched a Full Lifecycle AI and High‑Performance Computing data‑center solution earlier in 2025. The offering includes design, mechanical and electrical work, network integration, and advanced liquid cooling to handle ultra‑dense racks. The firm traces its roots to early contracting work in the region, expanded by acquisitions of electrical firms, and now positions itself to support AI workloads and HPC deployments with end‑to‑end services and vendor‑neutral delivery.
Planning and zoning background for the Chantilly site
The Chantilly parcel at Lee Jackson Memorial Highway and Stonecroft Boulevard was rezoned earlier in the year to allow a roughly 402,000 square‑foot data center. Initial plans had hinted at a taller building, but the approved facility is being developed at a lower height than originally discussed. The application drew sustained neighborhood opposition, including a neighborhood fundraising effort for legal action that has since closed. County planners had recommended approval months earlier and the board moved the rezoning forward after hearings.
