T5 Project Charlie Brings a Fuel-Cell Data Center Plan to Chantilly

T5 has submitted a plan for a 312,000-square-foot data center in Chantilly, Virginia, pairing a two-story building with onsite natural-gas fuel cells. Project Charlie offers an early look at the organizations, infrastructure interfaces and potential specialty work behind a new Northern Virginia facility. Its construction schedule and procurement path remain open.

As checked October 12, Fairfax County's SE-2026-SU-00038 application record carries a Waiting for Information status. That establishes a live proposal. It does not establish final approval, a construction start or an available bid package. No specific AI tenant or workload is disclosed in the documents reviewed.

The site and building in the filing

The applicant's September 18 statement of justification describes approximately 18.64 acres northeast of Lee Road and Stonecroft Boulevard. It identifies T5 Data Centers, LLC as contract purchaser. The county lists T5 Properties (GA), LLC, also known as T5 Properties, LLC. Those names belong to the project's documented application history; a completed acquisition has not been independently verified.

Item	Filed proposal	Qualification
Location	Chantilly, Fairfax County	Lee Road / Stonecroft Boulevard
Site	About 18.64 acres	Contract-purchaser description
Building	312,000 square feet	Two stories; up to 75 feet
Office component	About 30,000 square feet	Included in building total
Critical load	50 MW design input	Preliminary acoustic study
County status	Waiting for Information	Checked October 12
Capital budget	Undisclosed	Financing also unverified
Delivery	Dates unverified	No confirmed construction start

The office area is part of the 312,000-square-foot building. Adding it again would overstate the development. The planning documents describe a building and its supporting equipment areas, without establishing how future tenant fit-out packages would be purchased or divided.

Location discipline matters here. FFXnow's October 9 reporting distinguishes this application from another proposal at 3721 Stonecroft Boulevard involving former police-training land. The shared road name is insufficient to combine their parcels, approvals or contractors. The Chantilly map reference available for this report is locality-level; a verified site entrance is still needed for logistics.

Four power figures with different meanings

The September 18 letter proposes approximately 48 MW of fuel-cell electricity and up to 27 MW from Dominion Energy. Emergency generators form a third supply component. The applicant expects Washington Gas to provide fuel through an offsite extension. These are proposed arrangements; executed service agreements and delivery dates were not established in the reviewed material.

A separate September 17 environmental noise study from Trinity Consultants references a Corgan campus plan dated July 30. Its page-seven model table lists 50 MW of critical load and a 60 MW fuel-cell yard containing 24 units. The later applicant letter uses 48 MW for fuel-cell supply. The available documents do not explain the difference.

Both figures therefore need their dates and definitions attached. Redundancy, a revision, or a gross-versus-net distinction could conceivably account for different values, but none is verified here. Likewise, adding the proposed 48 MW and 27 MW supplies does not establish 75 MW of IT capacity. Supply components, modeled critical load and equipment-yard ratings answer different questions.

For prospective contractors, the practical issue is the final operating sequence. A controls or commissioning buyer would need to define which system handles alarms, which networks connect equipment, who owns failure testing, and how utility and onsite-power interfaces are accepted. Those are questions to resolve during procurement. The current figures cannot support a cable count, equipment bill or firm labor estimate.

The named team and the limits of each role

The filings identify a useful group of development and consulting organizations. Their documented roles vary considerably. The applicant letter supports the plat, transportation and legal roles; the acoustic report supplies the reference to Corgan's campus plan. Corporate websites verify identities and provide starting points for company research.

Organization	Documented role	Evidence boundary
T5 Data Centers	Developer / contract purchaser	Land closing unverified
Urban Ltd.	Special-exception plat	September 18 applicant letter
Trinity Consultants	Preliminary acoustic study	Modeled equipment and sound
Corgan	Campus plan designer	July 30 plan cited by Trinity
Wells & Associates	Transportation consultant	Applicant's stated role
Walsh, Colucci, Lubeley & Walsh	Land-use counsel	Applicant letter by Allison Reynolds
Dominion Energy	Proposed grid supplier	Service commitment unverified
Washington Gas	Proposed gas utility / extension owner	Applicant expectation

No general contractor, electrical contractor, fiber contractor, security integrator or commissioning provider is established for Project Charlie. No fuel-cell vendor is confirmed. Corgan's credited plan does not independently establish the final architect-of-record contract, and Urban's plat work does not establish responsibility for every engineering discipline.

This distinction makes outreach more useful. A development or entitlement contact may be able to identify the delivery team or explain the next milestone. It should not automatically be treated as the buyer for structured cabling. Before investing estimating time, a specialty firm should establish the contracting entity, procurement contact, design maturity and package boundary.

Where low-voltage work could emerge

The following opportunities are LVN's analysis of the proposed facility. They are prospective work categories, with no verified trade awards or open solicitations. The building, office component and multiple equipment systems provide a basis for asking focused questions about pathways, connectivity and integration.

System	Potential work	What needs confirmation
Fiber / outside plant	Entrances, duct banks, splicing, testing	Carriers, routes and package buyer
Structured cabling	Pathways, labeling, support networks	Specifications and fit-out boundary
Security	Access control and video coverage	Integrator, design and hardware
Fire alarm	Monitoring and equipment interfaces	Design, acceptance and scope owner
Controls / networking	Power and cooling telemetry	OEM interfaces and IT/OT boundary
Commissioning support	Network tests and turnover records	Test plan and responsibility matrix

For outside-plant firms, an early review would ask where diverse entrances can be accommodated and how telecom routes interact with utility work. The proposed gas extension raises coordination questions about civil sequencing and crossings. No route, easement, carrier commitment or detailed underground configuration is verified, so these remain subjects for design review.

For cabling and security firms, the office and data-center portions could have different standards, acceptance processes and purchasing owners. A useful capability package would show relevant testing, labeling, pathway coordination and handover experience. Quantities and staffing should follow issued scope documents, especially if the eventual tenant controls part of the fit-out.

The power concept also warrants clear controls responsibilities. Equipment telemetry, alarm routing, operational networks and integrated testing can cross several subcontract boundaries. A bidder should ask who supplies interface information, who configures it, and who proves the complete sequence. Project Charlie's public documents do not settle those commercial or technical responsibilities.

Cooling and acoustics still depend on design

The applicant describes closed-loop chilled-water cooling with dry heat rejection. That description does not mean every water use disappears: filling, makeup, offices and other facility functions still need consideration. Environmental benefits described by the applicant should be evaluated against the eventual equipment, operating profile and supporting permits.

Trinity's preliminary study is useful evidence of a design process. Its modeled outcome depends on equipment assumptions and mitigation, and later field verification remains material. An acoustic prediction cannot establish the sound of an operating facility that has not yet been built.

For specialty contractors, enclosure geometry and equipment placement can affect access, pathways and installation sequencing. Changes intended to address sound or screening can also change where an installer can work. The commercially useful milestone is a coordinated design with clear responsibility for revisions, testing and closeout.

Jobs, trades and preparation

The applicant forecasts up to 50 full-time-equivalent operating positions. That figure is a planning expectation. Construction headcount, actual openings and trade-by-trade demand remain unknown. A permanent staffing estimate should not be used to calculate a construction crew requirement or promise employment.

Technicians interested in this category of work can prepare around demonstrable skills: fiber inspection and cleaning, splicing and acceptance testing, pathway installation, grounding and bonding, labeling, as-built records, controls networking and commissioning support. The useful evidence is the ability to complete and document work to the eventual buyer's requirements.

The Fiber Optic Association's workforce resources provide a starting point for fiber training. OSHA's Outreach Training information explains general safety education. Neither resource establishes a Project Charlie credential mandate, hiring relationship or site-access entitlement. Employer onboarding, lift qualifications and project-specific rules would need separate confirmation.

Milestones that would make the opportunity more concrete

The next useful evidence is an application update explaining the outstanding information and subsequent review milestones. Land control, tenant commitments and financing would sharpen the commercial picture. Final utility arrangements and a reconciled fuel-cell design would improve confidence in the infrastructure schedule.

For subcontractors, named delivery leadership and actual package buyers are especially valuable. Issued drawings, solicitation dates, prequalification instructions and award notices would turn a documented proposal into a more actionable sales opportunity. Until those appear, a measured approach is to research the named organizations and prepare a relevant capability statement.

Use LVN Signal to research construction projects, follow named companies and assess where fiber, cabling, security and controls capabilities fit. Project Charlie currently offers a credible early-stage lead, with the capacity discrepancy and procurement gaps visible alongside the opportunity.
