DataBank, a Dallas-based data technology firm focused on colocation, interconnection, and managed cloud services, plans to add to its data center campus in Plano next year.

“The Plano campus design streamlines this expansion as we had already created scalable space and power options for customers requiring higher-density colocation services,” DataBank vice president of construction Tony Qorri said in an announcement posted on the company’s website.

“The expansion of our very first data center also syncs with the growing importance of the Dallas area in the data center ecosystem that connects users across the U.S. and South America,” he added.

DataBank acquired the initial development on Dominion Parkway between Headquarters Drive and Hedgcoxe Road from Stream Data Centers, a subsidiary of Dallas-based Stream Realty, which built a 145,000-square-foot data center with the ability to grow.

According to a filing with the Texas Department of Licensing and Regulation, DataBank will build a three-story core and shell and partial fit-out at 8735 Dominion Pkwy. The cost of construction for the capital-intensive development, with Corgan slated as the design lead, is valued at about $280 million.

When Stream Data Centers built the property, it was powered by two 20-megawatt underground utility feeds from a pair of Oncor substations and served by four fiber routes for redundant connectivity.

DataBank will use the facility, called DFW 3, to deliver power to its other Dallas data centers within 30 miles of Plano.

Meanwhile, Stream Data Centers plans to start construction of a $20 million addition to its Wilmer facility in southern Dallas County in January.

DataBank owns 68 data centers in the United States, including locations in Dallas, Houston, Austin, and Waco. It also has a data center in the UK. The firm announced earlier this week that it raised $533 million in debt and equity to further fuel its growth.
