Colocation provider Stack Infrastructure has announced plans to expand its Chicago data center campus with the construction of a new multi-story data center. This will be the company’s second data center in Chicago.

The new facility will be sited adjacent to Stack’s existing facility, which currently offers 13MW of critical power and 221,000 square feet of space. As announced, this second data center will offer at least 20MW of additional critical capacity, with the possibility of additional growth, bringing Stack’s total capacity at its Chicago campus to at least 33MW.


“Chicago is one of a number of important and growing markets for our clients, and as a result, it is a key market for Stack. We’re committed to investing here so that we can continue to support our clients and stay ahead of their needs,”
Brian Cox, CEO of Stack Infrastructure.

Stack Infrastructure was formed in January this year, by data center investor IPI Partners. It started with assets acquired from Infomart Data Centers and T5 Data Centers, giving the company a US footprint of eight data centers in six markets, spanning 1.5 million square feet of space and 100 megawatts of capacity. This initial footprint was a combination of Infomart’s facilities in Ashburn, Virginia; Portland, Oregon; and Silicon Valley, California – along with T5’s data centers in Atlanta, Georgia; Chicago, Illinois; and two in Dallas/Fort Worth, Texas.

Just one month after Stack was formed, the company secured an $850 million investment fund to build more data centers and grow its footprint in the States. This a timely investment, as Illinois recently implemented sweeping tax breaks for data center developers in the state.

The new Illinois law requires data center owners and tenants to invest a minimum of $250 million in capital expenses in the state within a five-year period, in order to qualify for the tax breaks. This is certainly not a problem to Stack, due to its recent funding.

“In keeping with our core commitment to being a trusted partner, this project delivers on our promise to strategically evolve and align our offering with our clients’ growth trajectories,”
Cox concludes.
