US data center firm Stack Infrastructure has acquired two vacant parcels zoned for data center development in Manassas in Virginia.
BizJournal reports, citing county records, that a Stack affiliate bought 30.8 acres at 9530 Hornbaker Road for $25.4 million in September from the Peterson Companies. The company then purchased nearly 32 acres located at 9650 Hornbaker Road for $26.14 million the same month.
In early 2020 the two companies announced plans for a 125-acre data center campus in Prince William County, Virginia. The first phase spans 25 acres with 700,000 square feet (65,000 sqm) of data center space and 72MW of critical capacity. At full build-out, the build-to-suit campus could reach 250MW of critical load and 4 million sq ft (371,600 sqm) of data center space.
Taylor Chess, president of development for the Peterson Cos., confirmed to BJ that the land purchases by Stack were part of this previously announced campus. Peterson is serving as the project's developer.
“That rounds out the entire campus. All of the properties that we had originally assembled and rezoned is on that Hornbaker campus,” Chess said. “Different sites were ready at different times. That’s why it didn’t look contiguous at the time.”
Three of the four buildings on the campus are already built or in development. A substation is also planned. It acquired an additional 25 acres in May 2021 and announced phase two expansion of the site in October 2021, aiming to bring an additional 36MW of capacity online starting in Q4 2022.
“Now that they’ve acquired the other two sites, they’ll probably start building [on] those relatively soon,” Chess said. “All of the development on the Hornbaker property is well underway.”
The Hornbaker site is one of three data center campuses Stack has in development in Northern Virginia.
Stack acquired two plots of land in Manassas from AWS in December 2021, and subsequently announced plans for a 34-acre, 84MW data center campus; the project will comprise a minimum of two buildings spanning 602,000 sq ft (56,000 sqm); the first phase will be delivered in Q3 of 2023.
The company is also developing a 216MW campus in Ashburn, in neighboring Loudon County. The 80-acre campus will support three buildings totaling almost 1 million sq ft (92,900 sqm).
