How an Old Caterpillar Site Could Power Data Centers

A 100-acre brownfield sitting idle doesn't just represent wasted space — it represents wasted potential. When aldermen in a Caterpillar-adjacent municipality started floating the idea of annexing a former Caterpillar site and selling it to data center developers, most people heard a zoning story. What's actually unfolding is something more interesting: a preview of how mid-sized American cities might solve two problems at once.

Industrial land without a tenant is expensive to maintain, environmentally complicated, and politically awkward. Data center developers, meanwhile, are in an aggressive land acquisition cycle driven by AI infrastructure demand, hyperscaler expansion, and a power grid that's finally catching up to digital appetites. The collision of those two realities — stranded industrial assets and a hungry data center market — is creating opportunities that didn't exist five years ago.

The Case for Repurposing Industrial Sites

Old manufacturing sites come with infrastructure that would cost a greenfield developer years and millions to replicate. Heavy electrical feeds, reinforced foundations, rail or highway access, and stormwater systems — these are exactly the bones a data center needs, even if the building itself gets demolished or retrofitted.

Brownfield redevelopment for data centers isn't just economical; it's often faster than building from scratch because half the site work is already done.

The Caterpillar site in question spans roughly 100 acres — that's significant. For context, a hyperscale campus from a major cloud provider typically needs 50 to 200 acres depending on cooling approach and build-out phasing. A 100-acre former industrial parcel hits the sweet spot: large enough to attract serious institutional or enterprise development, compact enough to manage infrastructure integration without massive grid expansion.

The environmental upside is real, too, though it gets oversimplified in press releases. Repurposing industrial sites for data centers doesn't eliminate remediation costs — those still exist and can be substantial. What it does do is redirect private capital toward a site that might otherwise sit in regulatory limbo for decades. A developer motivated by a data center deal has the financial incentive to push through the remediation process that a municipality handling it alone often lacks the budget to do.

What's Already Working Elsewhere

This isn't a novel concept. It's a pattern.

In Northern Virginia — still the world's densest data center market — early campuses were built on former industrial and distribution land along the I-95 corridor. The existing electrical infrastructure and transportation access made those parcels attractive before data center demand became what it is today.

In the UK, the former Battersea Power Station district attracted data center interest precisely because the electrical substation capacity was already there. In the U.S. Rust Belt, former steel and auto manufacturing sites in Ohio and Pennsylvania have quietly been evaluated by colocation providers looking for affordable land with legacy power infrastructure in place.

The lesson from these cases is consistent: the sites that close fastest are the ones where power delivery doesn't require years of utility negotiation.

That's where the Caterpillar site has a genuine edge. Caterpillar's manufacturing operations consumed serious industrial power. That existing utility relationship — the transformers, the feeds, the interconnection agreements — doesn't disappear when the machines leave. A sophisticated data center developer will evaluate that electrical legacy before anything else.

What Developers Actually Look For

Site selectors at data center companies run through a short list of non-negotiables: available power (typically 20–100+ MW for a campus build), fiber connectivity or the ability to bring it, distance from flood plains, zoning flexibility, and land cost per acre relative to competing markets. Former industrial land checks most of those boxes structurally. The wildcard is always environmental — Phase I and Phase II environmental assessments can reveal contamination that changes the financial calculus entirely.

The annexation angle here is worth watching closely. If the site currently sits outside city limits, annexation isn't just a formality. It determines which jurisdiction's zoning code applies, what tax incentives are available, and which utility district provides power. Those details can mean tens of millions of dollars in project economics over a 20-year data center lifecycle.

Navigating Annexation Without Losing the Deal

Municipal annexation processes vary dramatically by state, but they share common friction points: notice requirements, public hearings, opposition from existing landowners in the affected area, and timeline uncertainty. For a data center developer with capital deployed and a hyperscaler customer waiting on capacity, timeline uncertainty is poison.

Cities that want to attract data center development need to understand that they're competing with shovel-ready sites in tax-advantaged markets — Northern Virginia, Phoenix, Dallas, Atlanta. Those markets have streamlined their approval processes specifically to capture this investment. A city that takes 18 months to annex and rezone a parcel while a competing market closes in six will lose the deal.

The cities winning data center investment right now are the ones treating site entitlement like economic development, not just land use administration.

Community engagement matters here, and not just as a regulatory checkbox. Data centers generate significant property and sales tax revenue but relatively few jobs per square foot compared to manufacturing. An alderman who promises 500 new jobs to constituents and delivers a 50-person data center staff will have explaining to do. Managing that expectation gap upfront — while emphasizing tax base growth, utility revenue, and indirect employment in construction and services — is the difference between a project that sails through public hearings and one that becomes a political flashpoint.

That said, data centers don't require the same community amenity tradeoffs as, say, a warehouse distribution center. They don't generate heavy truck traffic at 3 a.m. They run quietly and consume enormous amounts of electricity and cooling water, which creates its own infrastructure considerations, but the neighborhood friction is typically lower than comparable industrial uses.

Where Urban Land Use Is Heading

The push toward repurposing industrial sites for data centers is accelerating for structural reasons that won't reverse. AI model training and inference are doubling compute demand faster than greenfield development can absorb. The hyperscalers — Microsoft, Google, Amazon, Meta — have each announced capital expenditure plans in the range of $50–100 billion annually for the next several years, and a significant portion of that is real estate and construction.

At the same time, the easiest suburban greenfield sites in established data center markets are getting picked over. Developers are being pushed into secondary markets — and that means mid-sized cities with underutilized industrial land are suddenly on the radar in ways they weren't in 2020.

The sustainability angle is becoming a real market driver rather than just marketing. Data centers built on remediated brownfields can legitimately claim lower lifecycle carbon footprints than those built on greenfield land — a claim that matters to corporate sustainability teams signing long-term colocation contracts. Water-efficient cooling designs, onsite renewable generation, and grid carbon content are all entering procurement decisions at the enterprise level.

Emerging technologies — particularly immersion cooling and direct-to-chip liquid cooling — are also relaxing some of the traditional site constraints. Data centers are getting denser and more thermally manageable in tighter footprints, which means a 100-acre site could support more compute capacity than the same acreage would have five years ago.

Making the Opportunity Real

The Caterpillar site story is still in early innings. Aldermen floating an idea is not a deal. Annexation is not entitlement. And developer interest is not a signed lease. But the underlying logic is sound, and the market timing is as favorable as it's ever been for this type of urban land use conversion.

What separates cities that capture this moment from those that watch it pass is process speed, transparency on environmental conditions, and realistic economic expectations communicated early. Hire a site selection consultant before you go to market. Understand your power capacity and be ready to share that data with developers in the first conversation. Know your remediation status and have a position on who bears that cost.

The former industrial sites sitting in mid-American cities right now aren't liabilities waiting to be written off. For the right developer, at the right moment, with the right infrastructure underneath — they're exactly what a power-hungry digital economy needs.
