Stack affiliate SAC III Acquisition to acquire up to 2,990 acres at Southern Virginia Megasite for data center development

SAC III Acquisition has the option to purchase 2,990 acres. The property may be purchased in phases, with the first phase including at least 1,000 acres in a deal that must complete by June 2027. The deal is reportedly contingent on sourcing 299MW of grid capacity by the end of 2028 from Appalachian Power. Stack could invest up to $73 billion into the site, according to VB, over a 30-year period. The Southern Virginia Megasite at Berry Hill totals 3,528 acres. Electrical service is provided through American Electric Power (AEP) via an existing new double-circuit 138kV substation that provides 100MW of immediately available power capacity. The site is located next to a 125MW solar facility, with 55MW battery storage that has been approved and set to go live in 2027, and has direct access to the Williams Transco Pipeline via an existing gate station on-site. In January, the Pittsylvania County board of supervisors and planning commission unanimously approved the creation of a new heavy industry zoning district, called M-SVMS, and applied it to the megasite, providing by-right zoning for industrial developments, including data centers.
