Quantum Loophole has sold a plot of land at its campus in Frederick County, Maryland.

The company, which develops gigawatt-scale master-planned data center parks, this week announced the sale of 150 acres at Quantum Frederick.

Details including the buyer and terms were not shared.

“We are excited to welcome a new customer to the Quantum Ecoscale campus,” said Josh Snowhorn, founder and CEO of Quantum Loophole. “Our site in Frederick, Maryland is unlike any other data center siting opportunity currently available. Our approach to delivering land, power, water, and connectivity while designing in partnership with nature is changing the way industrial developments work in concert with the environment.

"We look forward to ongoing collaborations with our customers to bring above and beyond value to residents of Frederick and the entire state of Maryland.”

Maryland isn’t currently a major data center market, but the Quantum Loophole campus, near Adamstown just north of Virginia's Loudoun County, is seeking to create a massive data center park that could reach up to 2GW.

Led by former Terremark and CyrusOne executive Snowhorn, the company has partnered with TPG Real Estate Partners (TREP) and is developing a 2,100-acre, park on the former Alcoa Eastalco Works aluminum smelting plant site.

Maryland recently amended its regulations around backup generators, easing restrictions for data center firms. The move was celebrated by Quantum Loophole, which claims it lost a customer due to the previous requirements.

Quantum’s first tenant, Aligned Data Centers, wanted 168 diesel generators capable of delivering 504MW for its full build on the site. Aligned wanted its generators to be treated individually, and to get an exemption from the CPCN process, but the state's Public Services Commission (PSC) rejected the request.

The company then pulled out after a hearing in which the PSC only granted it a provisional exemption for up to 70MW of diesel generators. Aligned had planned to build 3.3 million sq ft of data center capacity.

A second data center builder, Rowan Green Data, has also announced plans to develop another part of the campus. The company aims to build a 750,000-square-foot (69,680 sqm) data center on a 151-acre plot within the planned park.

Quantum is also developing a fiber loop linking the campus to Ashburn, Virginia.
