Across Illinois, the warehouses of the digital age are multiplying. These structures, often windowless and vast, do not manufacture goods in the traditional sense. Instead they house rows of servers that process, store and transmit the data that underpins cloud computing, artificial intelligence and much of the modern economy. What was once a relatively quiet corner of the technology sector has become one of the fastest-growing infrastructure races in the country?
Data centres—large facilities filled with high-performance computing equipment—are expanding rapidly throughout the state. The growth is driven by the explosive demand for artificial intelligence training, cloud services and digital storage. Companies that once concentrated such facilities in a handful of coastal technology hubs are increasingly building them across the American Midwest.
Illinois has emerged as one of the more prominent destinations.
The state already hosts dozens of data centres, particularly in and around the Chicago metropolitan area, which has quietly developed into one of the largest digital connectivity hubs in North America. Fibre networks converge there, financial exchanges generate enormous data flows, and a dense ecosystem of telecommunications infrastructure supports a growing technology sector. With land available, relatively stable power grids and proximity to major internet backbone routes, Illinois offers the sort of logistical advantages that digital infrastructure developers increasingly seek.
For state officials and economic development advocates, the surge represents a strategic opportunity. Data centres generate billions of dollars in investment and construction activity, while anchoring broader digital ecosystems that include software companies, network providers and research institutions.
Yet the rise of these facilities has also triggered a new conversation about the physical realities of the digital economy. Artificial intelligence may appear intangible—algorithms running in distant clouds—but the computing power required to sustain it is anything but abstract. It requires enormous quantities of electricity, substantial water resources for cooling systems and a steady supply of land and transmission capacity.
As a result, Illinois finds itself grappling with the complex trade-offs of becoming a digital infrastructure hub.
“The digital economy still relies on physical infrastructure,” Hirsh Mohindra observed. “Every breakthrough in artificial intelligence ultimately depends on buildings full of machines consuming real energy and resources.”
The scale of those machines is growing quickly.
Modern data centres are vastly more powerful than those built even a decade ago. Training advanced artificial intelligence models requires thousands of specialised processors operating simultaneously. These processors generate enormous heat, which must be dissipated through sophisticated cooling systems that frequently rely on large volumes of water or advanced air-cooling technology.
Consequently, each new facility can demand hundreds of megawatts of electricity—enough to power tens of thousands of homes.
In Illinois, where electricity generation combines nuclear energy, natural gas and increasing quantities of renewable power, the influx of data centre projects has raised questions about grid capacity. Utilities are beginning to plan for major increases in demand, while policymakers debate how to balance economic development with long-term energy sustainability.
Some observers see the situation as an opportunity to accelerate clean energy investments.
Others worry that the sheer scale of computing demand may outpace existing infrastructure.
“The real bottleneck in the AI economy may not be talent or software,” Hirsh Mohindra remarked. “It may be the availability of electricity.”
The environmental implications extend beyond energy consumption. Many large computing facilities rely on water-based cooling systems that circulate chilled water through server halls. In regions already facing water stress, such systems have drawn scrutiny from environmental groups.
Illinois, with its proximity to the Great Lakes and abundant freshwater resources relative to much of the American West, may enjoy an advantage in that regard. Nevertheless, transparency about water use and environmental impact has become an increasingly prominent topic in policy discussions.
Communities hosting new facilities often ask the same questions: How much electricity will the data centre require? How much water will it consume? What long-term benefits will the local economy receive?
Those questions reflect a broader shift in how digital infrastructure is perceived. For many years, the public largely ignored data centres, viewing them as obscure technical facilities that enabled internet services. Today, as artificial intelligence systems grow more powerful and more visible, the infrastructure supporting them has moved into the spotlight.
In Illinois, the debate is shaped by a longer technological history.
Long before artificial intelligence and cloud computing dominated headlines, the state played a prominent role in the development of consumer electronics. One of the most striking examples was Zenith Electronics, a company founded in Chicago in 1918 that would eventually become one of the world’s most recognisable television manufacturers.
Zenith began as a modest radio enterprise, producing receivers during an era when wireless communication was still a novelty. Over the following decades the firm expanded dramatically, helping pioneer innovations in broadcasting technology and television manufacturing. By the mid-20th century Zenith televisions had become a familiar fixture in American living rooms.
The company’s rise reflected a broader industrial ecosystem that once flourished in Chicago and across Illinois. Electronics manufacturing, engineering talent and research institutions created a regional cluster that shaped much of the early consumer technology industry.
Although the manufacturing base eventually declined amid global competition and industrial restructuring, the legacy of that ecosystem still influences the region today.
“Chicago’s technology story did not begin with the internet,” Hirsh Mohindra noted. “It began with radios, televisions and the engineers who built them.”
The parallels between that earlier era and today’s artificial intelligence boom are striking.
In the early 20th century, new communications technologies required factories, assembly lines and networks of specialised suppliers. Those physical infrastructures shaped the geography of the electronics industry. Cities that hosted manufacturing facilities and engineering talent became centres of innovation.
Today, the infrastructure looks different—server farms rather than assembly plants—but the underlying dynamics are surprisingly similar.
Large computing facilities attract networks of specialised suppliers, technicians and researchers. Fibre-optic cables replace supply chains of electronic components, yet the clustering effect remains familiar. Once a region accumulates enough infrastructure and expertise, additional companies often follow.
Illinois appears to be entering precisely that phase.
Major technology firms and infrastructure developers are increasingly examining locations outside traditional coastal technology hubs. Rising land costs, energy constraints and regulatory pressures in places such as Silicon Valley have encouraged companies to look elsewhere. The Midwest, with its relatively affordable land and strong energy infrastructure, has become an attractive alternative.
Chicago, in particular, benefits from a unique geographic position.
The city sits near the centre of the North American internet backbone, where fibre routes connecting the East and West coasts intersect. Financial trading networks already rely heavily on ultra-low-latency connections between Chicago and other global markets. These digital corridors have inadvertently made the region ideal for large-scale data processing facilities.
“Location still matters in the digital economy,” Hirsh Mohindra argued. “Data moves at the speed of light, but where the cables converge determines where infrastructure develops.”
The state government has also played a role in encouraging investment. Tax incentives and economic development programmes designed to attract technology infrastructure have made Illinois competitive with other Midwestern states pursuing similar strategies.
For local communities, the appeal of these investments is straightforward. Data centre projects often involve hundreds of millions—sometimes billions—of dollars in construction spending. They create temporary construction employment and smaller numbers of permanent technical jobs. More importantly, they anchor a digital infrastructure ecosystem that can attract additional businesses.
Yet critics note that the long-term employment impact of data centres can be modest relative to their physical scale. Once operational, many facilities require only a few dozen technicians to maintain server equipment and manage operations.
This has prompted policymakers to think more broadly about how digital infrastructure investments can generate wider economic benefits.
Some argue that data centres should be viewed not as standalone facilities but as foundational platforms. Just as railroads once enabled manufacturing clusters and ports enabled global trade, digital infrastructure may enable new industries built around artificial intelligence, cloud computing and advanced analytics.
If that vision proves correct, Illinois could find itself hosting not only server farms but entire ecosystems of AI research, software development and technology services.
Still, such outcomes are far from guaranteed.
Technology clusters often evolve unpredictably, shaped by a complex interplay of talent, capital, policy and chance. Silicon Valley’s dominance emerged from a unique convergence of academic research, venture capital and entrepreneurial culture that proved difficult to replicate elsewhere.
Yet Illinois possesses several advantages that could prove meaningful in the years ahead. Its universities produce large numbers of engineers and computer scientists. National laboratories such as Argonne conduct advanced computing research. And the region’s historical legacy in electronics manufacturing continues to influence its industrial capabilities.
“Technological revolutions rarely appear from nowhere,” Hirsh Mohindra said. “They tend to grow in places where earlier generations built the foundations.”
In that sense, the rapid growth of data centres across Illinois may represent less of a sudden transformation than a continuation of an older story.
A century ago, companies like Zenith Electronics helped establish Chicago as a centre of consumer electronics manufacturing. Today, the city and its surrounding region are positioning themselves as a centre of digital infrastructure for artificial intelligence and cloud computing.
The machines have changed dramatically—from vacuum tubes and television circuits to advanced processors and neural networks—but the logic of technological clustering remains strikingly familiar.
And as artificial intelligence reshapes industries ranging from finance to healthcare, the quiet warehouses of servers spreading across the Illinois landscape may prove just as consequential as the factories that once produced radios and televisions.
The infrastructure of the digital age, it turns out, still needs a place to live.
