Showing that there is no end in sight to growth of its massive data center campus in Ashburn, Virginia, DuPont Fabros has bought a 23-acre parcel next to the campus that already has four operational data centers.

The company's publicized expansion plans in Ashburn include two data centers: the ACC6 facility currently under development and the ACC7 facility planned for development sometime in the future.

DuPont reported the land acquisition in its second-quarter earnings report. Its revenue for the quarter grew $11.5m (19%) year over year to $70.8m. Its earnings-per-share for the quarter were $0.20 ÔÇô up from $0.13 reported for Q2 2010.

During the second quarter, DuPont signed three leases for a total of 3.25MW and more than 16,000 sq ft of raised floor. The average lease term on these deals was about 7 years.

So far in the third quarter, the company renewed a previous 9.6MW lease for another eight years and signed a new one for about 0.60MW.

Commenting on the results, DuPont CEO Hossein Fateh highlighted the company's near-term plans for bringing online additional capacity.

"In the third quarter, we will complete construction of our new developments in Santa Clara, California, and Ashburn, Virginia, on time and on budget," he said. "These two developments total 31.2MW and represent a 20% increase in our operating portfolio."

Existing data centers the company considers "stabilized" (either 85% leased or have been operational for at least two years) are almost completely full. These are six Virginia data centers and one facility in the Chicago market.

Together, the stabilized properties deliver about 138MW of critical power on 840,000 sq ft of raised floor.

Facilities that have yet to be stabilized include Phase I of the Piscataway, New Jersey, data center, Phase II of the Chicago data center, Phase I of the Santa Clara, California, data center and Phase I of one of the company's Virginia properties.
