MDC 7, LLC's 3 Million Sq Ft Data Center Proposal: What We Know and Why It Matters
MDC 7, LLC proposes a groundbreaking 3 million sq ft data center that could redefine infrastructure and sustainability standards.
A 3 million square foot data center isn’t just a building; it’s a city block that thinks.
To put that footprint in perspective: the Pentagon — one of the largest office buildings on earth — covers roughly 6.5 million square feet of floor space, including its five stories. MDC 7, LLC's proposed facility would represent nearly half that, purpose-built for compute. That’s not a campus expansion or a phased pilot. That’s a bet on where digital infrastructure is heading, placed in concrete and steel.
The data center proposal from MDC 7, LLC has drawn attention for good reason. Projects at this scale don’t emerge in isolation — they signal something about where capital is flowing, what the grid is being asked to support, and how developers are thinking about the next decade of infrastructure demand.
What MDC 7, LLC Is Actually Proposing
The core of the proposal is straightforward: a single data center development spanning 3 million square feet. At that scale, MDC 7, LLC isn't building a facility to serve one enterprise client. Projects of this size are typically designed as multi-tenant hyperscale campuses — the kind that attract cloud providers, AI compute operators, and government contractors simultaneously.
Hyperscale facilities of this magnitude typically draw power loads between 500 megawatts and 1 gigawatt — enough electricity to power hundreds of thousands of homes.
That power demand is arguably the most consequential number in any large data center proposal. It shapes the conversation with utilities, determines transmission interconnection timelines, and — increasingly — forces developers to bring their own energy solutions to the table rather than simply drawing from the existing grid.
Details on the specific location remain limited in early reporting, but site selection at this scale is never arbitrary. Developers of hyperscale campuses prioritize a specific checklist: proximity to fiber backbone infrastructure, access to large blocks of flat, developable land, favorable state and local tax environments, utility partnerships capable of handling massive load additions, and — critically in the current regulatory environment — access to renewable energy or the ability to co-locate generation on-site.
The Economic Footprint Beyond the Building
Infrastructure projects of this size generate two distinct waves of economic activity, and they’re easy to conflate.
The first wave is construction. A 3 million square foot development of this complexity will require years of work and thousands of skilled tradespeople — electricians, ironworkers, mechanical contractors, low-voltage specialists. The construction phase of comparable hyperscale projects has supported anywhere from 2,000 to 5,000 direct construction jobs over multi-year build timelines, with significant downstream spending in local supply chains, hospitality, and housing.
The second wave is the one that actually matters for a community long-term: permanent operations. Here’s where data centers get complicated. Modern hyperscale facilities are engineered for maximum automation, which means a building the size of a small town might employ only 200 to 500 permanent staff. That’s not a flaw — it’s the economics of the asset class — but it does mean local officials need to evaluate these projects primarily through tax base and utility revenue lenses, not job-count headlines.
The tax revenue calculus, however, is legitimately compelling. Data centers carry enormous assessed values and require relatively limited municipal services compared to manufacturing or residential development. For the right jurisdiction, a project like this can meaningfully shift the local fiscal picture.
Technology and Design at This Scale
A 3 million square foot data center built in 2024 or 2025 will look fundamentally different from the enterprise data centers of a decade ago. The industry has undergone a quiet revolution in facility design, driven almost entirely by the explosion of AI workloads.
Traditional data center design assumed power densities of 5 to 10 kilowatts per rack. AI training clusters — the kind of infrastructure that large language model development and inference at scale demands — routinely operate at 40 to 100+ kilowatts per rack. That’s not a linear increase. It requires completely rethought cooling architectures, including direct liquid cooling, rear-door heat exchangers, and in some cases full immersion cooling systems where server hardware sits submerged in dielectric fluid.
A facility of this scope also provides the design flexibility to pursue advanced energy efficiency metrics. Power Usage Effectiveness (PUE) — the ratio of total facility energy to IT equipment energy — has become the benchmark for operational efficiency. Best-in-class hyperscale facilities now achieve PUE ratings below 1.2, meaning less than 20% of total power consumed goes to non-compute overhead like cooling and lighting. Legacy enterprise data centers often run at 1.5 to 2.0. At gigawatt-scale power loads, that gap represents tens of millions of dollars in annual operating costs — and equivalent differences in carbon output.
The Clean Energy Equation
Any serious data center proposal at this scale will face intense scrutiny on energy sourcing, and rightly so. The math is unavoidable: a facility drawing 500 MW to 1 GW of power, operating around the clock, consumes more electricity annually than many mid-sized cities.
The developers who win the next decade of data center deployment won’t just be the ones who build fastest — they’ll be the ones who solve the energy sourcing problem most credibly.
The clean energy integration options for a project this size generally fall into three categories. First, Power Purchase Agreements (PPAs) with existing wind or solar generators — a procurement approach that’s mature but increasingly competitive as data center developers compete for the same renewable capacity. Second, on-site or co-located generation, where the developer builds solar, wind, or even nuclear capacity directly tied to the facility — a more capital-intensive approach that also provides grid independence. Third, long-duration storage integration, pairing renewable generation with battery or alternative storage technology to address intermittency.
MDC 7, LLC's approach to this question will ultimately determine how the project is received by regulators, utilities, and the communities hosting it. Increasingly, state permitting processes and utility interconnection queues give preference — or impose conditions — based on clean energy commitments. A vague pledge to "pursue renewable energy" won’t move the needle. Binding commitments with specific capacity targets and timelines will.
What This Project Signals for Infrastructure Development
The MDC 7, LLC proposal fits into a broader pattern that anyone tracking infrastructure development should understand: data center projects are getting larger, faster, and more capital-intensive simultaneously.
The demand drivers behind this aren’t cyclical — they’re structural. AI compute demand is doubling on timelines measured in months, not years. Cloud hyperscalers are competing aggressively for power-ready land with the right connectivity characteristics. The result is a development environment where 3 million square feet, which would have seemed audacious five years ago, is now a logical unit of scale.
For other developers and investors watching this proposal, a few lessons are worth internalizing. Land with transmission access is the scarce resource — not capital, not even permitting, in most markets. Developers who control sites with existing or near-term grid capacity have a durable competitive advantage. Community engagement isn’t optional at this scale; projects that arrive with economic benefits clearly articulated and clean energy commitments credibly structured move through the process faster and with fewer political complications.
The permitting and interconnection timeline for a project of this magnitude will likely span several years from proposal to energization. That’s not a deterrent — it’s the nature of the asset class. What matters is whether the underlying demand signal justifies the patience, and right now, every indication from the market says it does.
MDC 7, LLC is making a significant call on the future of infrastructure. The details of how they execute on energy, design, and community integration will determine whether this data center proposal becomes a template others follow — or a cautionary note about the gap between ambition and delivery.
