Wythe County carries no zoning ordinance, removing one approval layer but leaving state environmental permitting and utility interconnection as the operative constraints
Decision Focus
On June 4, 2026, Cardinal News reported that TAC Data Centers — a subsidiary of Atlanta-based private equity firm The Ardent Companies — announced plans for a data center campus in eastern Wythe County, Virginia, requiring more than one gigawatt of power capacity. The site sits adjacent to 765-kilovolt transmission infrastructure along Interstate 81. The operational signal for energy heads is not the project itself; it is what the project reveals about where the next viable interconnection opportunities are located, and what Appalachian Power has already put in place to govern them.
90-Second Brief
In recent days, tAC Data Centers is planning a 9 to 11 building campus spanning 3.5 to 4 million square feet on roughly 1,000 acres in Wythe County, with a target of first-phase operations in 2029 and full build-out by 2031 or 2032. The project falls inside Appalachian Power’s service territory, which recently completed a regulatory case before Virginia’s State Corporation Commission establishing binding requirements, including multi-year commitments and minimum billing obligations, for customers requiring at least 100 megawatts individually or 150 megawatts aggregated. Wythe County carries no zoning ordinance, removing one approval layer but leaving state environmental permitting and utility interconnection as the operative constraints. The broader pattern is Southwest Virginia absorbing demand overflow from a saturated Northern Virginia market.
What Is Really Happening?
The choice of Wythe County is explicitly a transmission-proximity decision. TAC cited access to 765-kilovolt high-voltage lines as a primary site selection factor — a voltage level that signals the developer is engineering for scale from the start, not planning to grow into large loads incrementally. At 1GW, this project represents a material addition to a regional utility’s load base.
What makes this development consequential beyond its scale is Appalachian Power’s recently completed regulatory framework. The utility has now established formal rules governing how large-load customers connect, what financial commitments they must accept, and how costs are protected from flowing to existing ratepayers. That framework did not exist in this form a year ago. Its completion means any operator evaluating Southwest Virginia interconnection must work within a defined cost-allocation and commitment structure — one that rewards early engagement but imposes binding minimums that change the financial model for speculative or phased capacity strategies.
The secondary market theme is also accelerating. Google has a project in Botetourt County. Stack Infrastructure is developing in Pittsylvania County. A separate AI-focused operator, Solis Arx, is already underway in Wythe County itself. Southwest Virginia is functioning as a structural relief valve for a Northern Virginia market where land costs, grid congestion, and regulatory friction have reached levels that push even well-capitalized developers to look elsewhere.
Why It Matters for Global Heads of Data Center Energy
The immediate implication is interconnection queue strategy. A 1GW reservation on Appalachian Power’s system — if filed — will occupy substantial capacity on transmission infrastructure that other large-load operators may also be targeting. Any energy head who has flagged Southwest Virginia as a medium-term site option needs to know where TAC sits in the queue relative to their own planned projects.
The Appalachian Power regulatory case is equally significant. The new framework creates a cost-allocation structure that differs from what Northern Virginia operators have typically negotiated with Dominion Energy. Multi-year minimum billing commitments are a financing variable, not just a utility relations issue — they affect how phased campus build-outs are modeled, since minimum billing obligations may apply before full load is drawn.
The absence of county zoning in Wythe County removes a layer of local approval risk that has delayed projects elsewhere in Virginia. But it does not eliminate community opposition as a timeline variable. The Solis Arx project in the same county has already drawn resident concerns at public meetings, and Wythe County officials are actively drafting a zoning ordinance in response to large-scale development pressure. An operator moving fast on the basis of the current permitting environment may face a materially different regulatory landscape by the time a project reaches the building permit stage.
Diesel backup generation for a 1GW campus also means a significant DEQ air permitting process. At this scale, that path warrants early engagement with state environmental regulators, not a late-stage compliance check.
Forward View
If Southwest Virginia expansion continues at its current pace, Appalachian Power’s transmission capacity will face stress requiring capital investment in new infrastructure — investment that may flow through rate cases affecting large-load customer costs. Watch for Virginia State Corporation Commission proceedings related to Appalachian Power transmission upgrades as a leading indicator of where interconnection timelines are heading in this corridor.
The drafting of a zoning ordinance in Wythe County is a second front worth tracking. If adopted before TAC or other projects secure local building permits, the regulatory environment for new entrants changes substantially. Projects already in permitting may be grandfathered; later entrants will not.
A third signal is whether other hyperscale or large colocation operators file competing interconnection requests in Appalachian Power’s territory. TAC’s announcement tests whether the market treats Southwest Virginia as a viable primary market or a secondary overflow option.
What Is Still Uncertain
The article does not confirm whether TAC has filed an interconnection request with Appalachian Power, or where such a request would sit in the existing queue. The 2029 first-phase target is TAC’s own projection; whether Appalachian Power can support that timeline given its current load growth trajectory and infrastructure program is not established. The specific terms of the multi-year minimum billing commitments in the new regulatory framework have not been disclosed publicly. Water supply sufficiency for a campus of this scale in Wythe County, despite TAC’s low-use cooling claims, has not been independently verified or permitted. And the county’s zoning ordinance remains in draft, creating genuine uncertainty about the approval environment for projects not yet under permit.
One Question for Your Team
If Appalachian Power’s new minimum billing framework applies to your planned or optioned capacity in this corridor, does your current project financial model account for the cost of that commitment during a phased ramp — and have you mapped your interconnection queue position relative to the 1GW request TAC is bringing to this territory?
