Sears Plans To Retrofit 2,500 "Ghostbox" Stores As Data Centers

There are over a billion square feet of vacant commercial space in the US right now, most of it in the form of big box stores. This being America, we’ve come up with plenty of intelligent ways to reuse the department stores at which we can no longer afford to shop: Churches. Parks. Clinics. And now, data centers.

This month, Sears announced the formation of a stand-alone company—the ominously-named Ubiquity Critical Environments LLC—to handle to conversion of thousands of Sears and KMart stores into data centers. Over the next few years, Ubiquity Critical will assess and convert more than 2,500 individual stores, basing its decision on store performance and demand. Ultimately, the structural skeletons of these stores will house servers, chillers, and generators, as well as roof-mounted antennas. In a crushingly ironic twist, the centers will target medium-sized e-commerce retailers—the very companies helping to put department stores out of business.


According to Crain’s, Ubiquity Critical’s name is derived from a compelling bit of data about Sears’ now-dwindling empire: 71 percent of the U.S. population lives within 10 miles of one of its buildings. It’s likely that we’ll see the centers pop up in areas like Colorado and Texas, where fledgling Internet businesses are more common than, say, rural Kansas:

Only properties in large data center markets such as Chicago and Dallas, on sites with the best access to power and fiber, will be suitable. Sears' properties likely will serve lower-tier users with smaller budgets. Demand is high for data storage, particularly for small and midsized companies that don't need the top-tier facilities that serve banks, airlines and other businesses that can't afford to go offline even for a moment.


The phenomenon of the “ghostboxes” is well known, and Sears’ decision definitely isn’t without precedent. After a tornado devastated Joplin, Missouri in 2011, the town converted an abandoned mall into a replacement high school in less than two months. Another ghostbox—this one in Wisconsin—recently re-opened as an alternative church. The same goes for parks, libraries, and playgrounds. But the idea that the physical infrastructure that powered the last century's retail revolution are now serving as skeleton housing for this era? That's new. [Crain's via Motherboard]
