Eminent Domain for Data Centers: When 'Public Use' Gets Stretched

The AI boom is driving a data center construction frenzy — over 3,000 centers exist in the U.S. with another 1,500 in development, per Pew Research. But a Gallup poll shows 70% of Americans oppose having these facilities in their communities, citing higher utility bills, pollution, noise, and loss of green space. The real flashpoint, however, is the transmission infrastructure needed to power them.

When landowners refuse to sell easements for new power lines, utilities are increasingly turning to eminent domain — the government's power to seize private property for 'public use' with 'just compensation,' as enshrined in the Fifth Amendment. But does a transmission line built primarily to serve a single private data center qualify as public use? That's the question now playing out in courts across the country.

The Legal Landscape

Eminent domain is typically delegated to states and local governments, which can pass that authority to private utilities. The U.S. Supreme Court's 2005 Kelo v. City of New London decision set a permissive precedent, allowing economic development as a valid public use — though that specific redevelopment project ultimately failed, and Pfizer left town. In response, 45 states enacted reform laws, and some state supreme courts (Michigan, Ohio, Oklahoma) now forbid taking property purely for private economic gain.

But utilities have historically fared better. Courts in South Dakota and Vermont have upheld power company seizures when the lines provided at least some in-state energy or grid reliability benefits. The calculus shifts when lines cross state lines and don't serve local customers. In 1984, the Mississippi Supreme Court rejected a condemnation because the line would have run from Mississippi to Louisiana without benefiting any Mississippi ratepayers.

What This Means for Engineers

If you're building or planning data center capacity, don't assume the power infrastructure will just materialize. Legal battles over eminent domain can delay transmission projects for years. The growing public backlash — and the patchwork of state-level reforms — means site selection and power procurement strategies need to account for regulatory and community risk, not just technical specs.

For those working on energy-intensive AI workloads, the grid reliability concerns are real: data centers already consumed over 4% of U.S. electricity in 2024, and that share is climbing. The transmission bottleneck isn't just a political story — it's a constraint that could affect where and how quickly new capacity comes online.
