Digital Realty Acquires 40-Acre Site in Rolling Meadows for Data Center Expansion

Executive Summary

Digital Realty's $81.5 million acquisition of the Atrium Corporate Centre in Rolling Meadows, Illinois, positions the global data center operator for a significant build-out in one of the Midwest's most active digital infrastructure markets. The deal signals sustained institutional confidence in the Chicago metro as a data center destination, even as power constraints and zoning complexity intensify across suburban Cook and Lake counties. Data center developers and infrastructure investors stand to benefit from the momentum this acquisition generates; local governments and legacy office stakeholders face the harder work of adapting land-use frameworks to accommodate large-scale digital infrastructure. The InfraSale takeaway: investors who map local zoning posture now will have a material edge when adjacent parcels and competing sites come to market.

What Happened

In September, Digital Realty purchased the Atrium Corporate Centre, a 40-acre site situated at the confluence of the Jane Addams Tollway (I-90) and Route 53 in Rolling Meadows, Illinois. The acquisition price was $81.5 million. The property, previously an office complex, sits at a highway intersection that offers strong road access and proximity to the dense fiber and power corridors that run through Chicago's northwest suburbs.

The site's acreage is meaningful. Forty acres provides room for a multi-building campus-style data center deployment, the kind of large footprint that hyperscale and enterprise tenants increasingly demand. Digital Realty has not publicly disclosed a specific development timeline or MW capacity target for the site.

Industry context: The Chicago metro data center market has expanded rapidly over the past several years, driven by enterprise cloud adoption, AI workload growth, and the region's established fiber density. Rolling Meadows and surrounding northwest suburban communities have seen increasing developer attention as closer-in sites near downtown become scarce.

Why This Matters

This acquisition is not an isolated transaction. It is a data point in a consistent pattern: institutional data center operators converting underutilized suburban office assets into digital infrastructure at scale. When Digital Realty — a $40-plus billion market cap REIT — commits $81.5 million to raw land and an office teardown or retrofit, it validates the northwest Chicago suburbs as a credible data center corridor for the near-to-medium term.

The I-90/Route 53 interchange is a logistics and infrastructure crossroads. That is not accidental site selection. Highway adjacency supports the heavy equipment, emergency fuel delivery, and construction staging that large data center campuses require. It also reflects proximity to transmission infrastructure that follows major road corridors throughout the Chicago metro.

The broader signal for the market: office-to-data-center conversions and greenfield data center plays in secondary suburban rings are accelerating. Developers who move early on comparable sites — 20 to 60 acres with highway access, existing utility easements, and favorable zoning — are likely to see those assets re-price as demand continues to outpace available inventory.

Power & Interconnection Impact

A 40-acre data center campus in this configuration could ultimately require 100 MW or more of utility power, depending on density and tenant mix. Industry context: hyperscale deployments routinely target 200–400 MW at build-out for sites of this scale, though phased development is standard. ComEd, the incumbent electric utility serving Rolling Meadows, will be the primary counterparty for load interconnection discussions.

The northwest Chicago suburbs already carry significant data center load. Adding another large campus will intensify pressure on existing substation capacity and may require transmission upgrades coordinated through the PJM interconnection queue — a process that, in the current environment, can run three to five years for large load additions. Assumption: Digital Realty's development team will have already initiated preliminary utility discussions, but formal interconnection filings are likely not yet public.

For investors and developers watching this corridor, the power situation is the critical gating factor. Sites with existing substation proximity or dedicated feeder capacity will carry a premium as this campus moves through its development cycle.

Land, Zoning & Permitting Impact

Rolling Meadows will need to address the land-use transition from commercial office to data center use. Data centers are not universally permitted in office or commercial zones; many municipalities classify them as industrial or utility uses, triggering a separate permitting track. The City of Rolling Meadows may need to amend its zoning code, process a special use permit, or engage in a planned development agreement before vertical construction can begin.

Environmental review is another variable. Redeveloping an existing office complex can surface soil conditions, stormwater management requirements, and impervious surface limits that add time and cost to the entitlement process. If any buildings on the Atrium Corporate Centre site contain materials requiring remediation, that timeline extends further.

InfraSale Marketplace

Turn this intelligence into a deal

InfraSale connects landowners, developers, and tenants directly — skip the broker chain.

Local governments in the Chicago metro have generally been receptive to data center investment — in part because of the economic development narrative and tax revenue potential. Illinois also maintains a data center sales tax exemption that makes the state structurally attractive for this asset class. However, community opposition to the visual and operational footprint of large data centers (generator noise, traffic, visual bulk) has become a more consistent feature of suburban permitting processes across the country.

Investment Takeaway

Office-to-data-center conversion plays are institutional-grade. Digital Realty's willingness to pay $81.5 million for a suburban Chicago office site underscores that well-located suburban land with highway access is being re-underwritten at data center land values, not office values.
Power is the binding constraint. Investors evaluating comparable sites in the Chicago metro should prioritize substation proximity and existing utility easements over raw acreage. Sites without a credible power path will not close on data center economics.
Zoning diligence is non-negotiable. The entitlement risk on a site like this is real. Investors should conduct zoning analysis — including special use permit history and municipal attitude toward industrial/utility uses — before moving to LOI.
Adjacent land markets will respond. Comparable suburban Chicago sites within the same highway corridors should see price pressure as this development advances through permitting.
Timing risk is a function of PJM queue position. Projects without a filed interconnection application face multi-year delays. That changes IRR math significantly and should be built into underwriting models.

InfraSale Market Angle

For investors actively sourcing powered land or data center sites in the Midwest, the Digital Realty Rolling Meadows acquisition is a directional signal — not a ceiling. The Chicago metro has runway, but the best-positioned assets are those with entitlement clarity, utility relationships already in motion, and acreage large enough for phased campus deployment.

Landowners sitting on highway-adjacent parcels in Cook, Kane, DuPage, and Lake counties should be assessing their sites against data center siting criteria now, before comparable transactions reset buyer price expectations. Developers should be filing preliminary interconnection applications with ComEd and tracking the PJM queue for capacity openings in the northwest Chicago transmission zone.

Understanding local zoning posture — specifically, whether a municipality classifies data centers as permitted, special use, or conditional use in relevant zones — is the first filter that separates actionable sites from expensive delays.

FAQ

What are the benefits of investing in data centers?

Data centers offer long-term, contracted cash flows through triple-net leases with creditworthy hyperscale and enterprise tenants. Demand is structurally supported by cloud adoption, AI compute requirements, and enterprise digital transformation — all of which are durable, multi-decade trends. As supply in primary markets tightens, well-located suburban sites are capturing premium valuations.

How does a large site acquisition like this impact local infrastructure?

A campus-scale data center draws significant new electrical load — potentially 100 MW or more — which requires utility upgrades, new substation capacity, and coordination with the regional transmission operator. Beyond power, large data centers also affect road infrastructure, stormwater systems, and emergency services planning. Local governments typically negotiate these improvements through development agreements tied to the permitting process.

What zoning considerations should I be aware of for data centers?

Data centers occupy an ambiguous position in most municipal zoning codes — they are sometimes classified as commercial, sometimes industrial, and sometimes as utility uses, each with different setback, noise, and aesthetic requirements. Special use permits or planned development designations are common requirements for large campuses. Investors should review the specific municipality's zoning ordinance and any overlay districts before underwriting a site.

Does Illinois offer any tax incentives for data center development?

Industry context: Illinois has an established sales tax exemption program for qualified data center investments, covering equipment and electricity purchases. This exemption has been a material factor in drawing large operators to the Chicago metro. Investors should verify current program thresholds and application requirements with the Illinois Department of Commerce and Economic Opportunity, as terms can change with state budget cycles.
