BizJournal reports the company plans to build two more data centers at 19540 Compass Creek Parkway, to be known as IAD02 and IAD03, according to Loudoun economic development documents and confirmed by executive director Buddy Rizer.

The data centers will total around 475,700 square feet (44,200 sqm) and sit on a portion of the roughly 323 acres Microsoft acquired from the Peterson Cos. in 2018 for $73 million.

Next to the Leesburg Executive Airport, the site is immediately south of two existing Microsoft facilities, known as IAD01-1 and IAD01-2, which together reportedly comprise more than 245,000 sq ft (22,750 sqm). Construction work began around 2019.

BJ reports the county approved the fast-track development application for the project in August 2020, meaning that Microsoft and its team can move forward with vertical construction as soon as they check off all the necessary approvals.

The campus can reportedly hold two more facilities – likely IAD4 and IAD6 – that could take the site’s capacity to a total of 180MW.

Elsewhere in Loudoun, Microsoft is looking to build a $400 million data center campus on 67 acres it owns in Loudoun County’s Arcola Business Park. The facility, to be known as IAD11 — will span 500,000 square feet (46,450 sqm) and is to be located on land the company acquired Arcola/Stone Ridge area of Loudoun in August 2020 for $93.7 million.
