Overview

The public and political debate around datacenters focuses heavily on the facility itself: the 800-acre site, the rezoning vote, the water consumption, the noise. What is less visible but increasingly consequential is the infrastructure overspill problem — the transmission lines, substations, fiber corridors, and water system upgrades needed to serve datacenters that extend far beyond the fence line of the facility and impose costs, including involuntary property takings via eminent domain, on people who had no standing in the original approval process.

This pattern is documented across multiple states as of 2025–2026. In every case, the mechanism is the same: a datacenter (or cluster of datacenters) generates load growth that exceeds local grid capacity, requiring new or upgraded high-voltage transmission infrastructure. Utilities, which hold eminent domain authority as regulated monopolies, then apply to state regulators to condemn easements or acquire land across the corridors of the new lines. Affected landowners may lose portions of their property, suffer devaluation of the remainder, and face construction disruption — all without being parties to the decision that created the demand in the first place.

The Infrastructure Overspill Mechanism

Why Individual Approval Doesn’t Capture the Full Footprint

When a local government approves a datacenter rezoning or development permit, the decision typically considers:

  • Impacts on the parcel itself and immediately adjacent properties
  • Local road and water/sewer infrastructure
  • Local tax and employment effects

What is typically not considered in the local approval:

  • Transmission grid upgrades required to serve the facility, which may run through distant counties
  • Aggregate load growth effects when multiple datacenters cluster in a region
  • Cost allocation for grid upgrades (who pays — ratepayers, developers, or the utility?)
  • Eminent domain exposure for landowners in the transmission corridor

This creates a regulatory gap: the decision-maker (local county commission, zoning board) is not the same as the entity that will bear the costs of the infrastructure (distant landowners; utility ratepayers statewide). The community that approved the datacenter captures the tax revenue and jobs; the communities in the transmission corridor bear the involuntary infrastructure burden.

The Transmission Line Problem

High-voltage transmission lines for grid-scale power (230 kV, 345 kV, 500 kV) require wide easements — typically 100–200 feet — and run for tens to hundreds of miles. They cannot be easily rerouted around individual properties. Utilities acquire these corridors through:

  1. Voluntary easement purchase: Negotiated payment to willing landowners
  2. Eminent domain condemnation: Forced taking at “just compensation” (appraised value), which may be contested

In the current datacenter-driven grid expansion, utilities are pursuing eminent domain for transmission lines across multiple states simultaneously, with affected landowners who have no connection to and received no benefit from the datacenters that created the demand.

Case Studies

Maryland: The “Extension Cord” for Northern Virginia

Project: Maryland Piedmont Reliability Project — 67-mile, high-voltage transmission line crossing Baltimore, Frederick, and Carroll counties

Utility: PSEG (New Jersey-based utility)

Purpose: The line would carry power to Northern Virginia’s “Data Center Alley” (Loudoun and Prince William counties), which hosts the world’s largest datacenter concentration. Maryland landowners and advocates called it an “extension cord for data centers.”

Eminent Domain Use: PSEG has floated using eminent domain to take farmland from landowners who refuse voluntary easements.

Community Response:

  • Landowners staked roadside signs reading “No eminent domain for corporate gain”
  • A court battle escalated into confrontations between farmers and land surveyors attempting to access properties for route surveys
  • Maryland farmers organized politically against the project
  • Maryland legislators proposed the Protect Maryland Farm Lands Act, which would require payment of 350% of the highest appraised value for any land taken by eminent domain for transmission lines — a premium designed to make eminent domain for datacenter-serving lines economically punitive

Status (2026): Legislative and regulatory battles ongoing.

Virginia: Dominion Transmission Loop in Loudoun County

Project: Dominion Energy transmission loop project in Loudoun County — a new set of high-voltage transmission lines through the heart of “Data Center Alley”

Utility: Dominion Energy (Virginia’s regulated monopoly utility)

Purpose: Grid reinforcement to serve the massive load from Loudoun County datacenters and the broader Northern Virginia growth corridor

Eminent Domain Risk: Virginia utility law allows Dominion to use eminent domain to acquire easements for transmission lines once approved by the Virginia State Corporation Commission (SCC). Some Loudoun County homeowners face the loss of property or significant property devaluation even if they do not voluntarily sell.

Cost Allocation Issue: Under Virginia’s current rules, residential and commercial ratepayers shoulder a substantial share of transmission infrastructure costs. Opposition groups have argued that hyperscale datacenter operators — whose load growth drives the need for the upgrades — should bear a larger share.

Key Quote: Reports noted that “for the first time in three years of Dominion working on a transmission loop project,” a specific property in Loudoun County was identified as the proposed location — a sign of how the process compresses previously abstract risk into individual homeowners’ specific situations.

Project: NextEra Midatlantic Resiliency Link — a 500 kV transmission line running from southwestern Pennsylvania through multiple states to serve Northern Virginia datacenters

Developer: NextEra Energy (Florida-based; largest US renewable energy company)

Route: Southwestern Pennsylvania → multiple states → Northern Virginia

Purpose: Deliver power specifically to the Northern Virginia datacenter cluster, which is the world’s largest by installed capacity and whose load growth has outpaced local generation

Eminent Domain Use: NextEra has filed for eminent domain authority in Pennsylvania, seeking to take land from homeowners and farmers in southwestern Pennsylvania — a region with no datacenters and minimal economic connection to the Northern Virginia market that will benefit

Affected Parties: Pennsylvania homeowners and farmers face potential loss of property or forced easements for a project whose primary beneficiaries are hyperscale datacenter operators (Amazon, Microsoft, Google, Meta) and their customers in another state

Regulatory Status: Pennsylvania Public Utilities Commission consideration ongoing as of April 2026

Community Opposition: Pennsylvania residents and officials have raised concerns about being made to bear risks for another state’s technology infrastructure buildout

Georgia: Ashley Park–Wansley 500 kV Line

Project: Ashley Park–Wansley 500 kV transmission line — 35 miles, Fayette County to Heard County, crossing Coweta County

Utility: Georgia Power (Southern Company subsidiary)

Purpose: Grid reinforcement for South Metro Atlanta, a region experiencing significant load growth tied to data center and industrial development. The corridor passes through Coweta County, the same county where Project Sail (900 MW, $17 billion hyperscale campus) was approved in April 2026.

Affected Parcels: 300+ private property parcels along the 35-mile corridor

Easement Width: Average 175 feet

Eminent Domain Risk: Georgia Power has eminent domain authority as a regulated utility. Property owners who do not agree to voluntary easements can have their land condemned.

Timeline:

  • Survey work begun 2025
  • Clearing/grading: Q1 2027
  • Construction: Q3 2027
  • Completion: Q2 2028

Relationship to Project Sail: Georgia Power’s stated rationale is broad regional grid reliability, not specifically Project Sail. However, the timing (announced December 2025, concurrent with Coweta County’s data center ordinance revision) and the corridor (through the same county) raise questions about the connection. Prologis claimed Project Sail’s proximity to Plant Yates would avoid new transmission line construction — a claim that is technically accurate for the specific Project Sail site but does not address the regional grid reinforcement that aggregate datacenter load growth is driving.

Key insight: This is the infrastructure overspill problem in practice. The datacenter itself sits on voluntarily rezoned or sold land. The power infrastructure needed to serve the broader region imposes eminent domain risk on 300+ property owners who had no standing in the Project Sail approval decision.

Structural Issues

The “Just Compensation” Problem

Eminent domain requires payment of “just compensation,” typically defined as fair market value (appraised value). But for farm families and rural landowners, the harms of a 175-foot transmission corridor may exceed appraised value:

  • A transmission line through a farm disrupts agricultural operations and may render portions of the field unworkable
  • Property devaluation from proximity to high-voltage infrastructure is often not captured in the compensation formula
  • Rural property markets are thin; comparable sales may not exist to establish accurate market value
  • Intangible harms (disruption to rural way of life, loss of viewshed, noise from transmission infrastructure) are typically uncompensable

The Maryland legislative response — proposing a 350% premium over appraised value — reflects recognition that standard “just compensation” systematically undercompensates involuntary takings for large infrastructure projects.

Cost Allocation: Who Pays for Grid Upgrades?

Utility cost allocation rules determine whether the cost of transmission infrastructure upgrades is borne by:

  • Ratepayers (all customers pay via rate base inclusion)
  • Large load customers (datacenters pay direct interconnection fees)
  • Developers (required to fund upgrades as a condition of approval)

Under current rules in most states, ratepayers — including residential customers with no connection to datacenter operations — shoulder substantial shares of transmission upgrade costs. Virginia’s existing rules put more than 50% of Dominion transmission upgrade costs on ratepayers; opponents have argued datacenters should pay a larger share as the load growth driver.

Claim Verification Status: Specific percentages vary by state and project. The general principle (that ratepayers bear some share of transmission upgrade costs) is broadly documented; exact allocation formulas require state-specific regulatory research. Treat specific percentages as indicative, not verified.

The “No Say” Problem

Perhaps the most fundamental structural issue is that the communities bearing infrastructure overspill costs have no formal standing in the process that creates the burden:

  • Datacenter approval: Made by the local county or municipality where the facility is sited. Nearby counties and transmission corridor communities are not parties.
  • Transmission line approval: Made by state utility regulators (state PUC or SCC), who balance utility reliability against landowner harm but do not have authority over the datacenter approval decision that created the need.
  • No integrated review process: No existing regulatory framework requires that the cumulative infrastructure footprint of a datacenter — including off-site transmission, substation upgrades, and water system impacts — be assessed and approved as part of the datacenter’s land-use approval.

This gap is a structural feature of how utility regulation and land-use regulation are siloed from each other.

Legislative Responses

Maryland: Protect Maryland Farm Lands Act (Proposed)

  • Would require 350% premium over highest appraised value for eminent domain takings for transmission lines
  • Framed explicitly as a response to transmission lines serving Northern Virginia datacenters
  • Status as of 2026: Proposed; not yet enacted

Virginia: Rate Class Reform (Partial)

  • Virginia created a new utility rate class for hyperscale datacenters, intended to better align datacenter costs with the grid upgrades they require
  • Critics argue the formula is insufficient and that ratepayers still subsidize the grid upgrades
  • Status as of 2026: In place but contested; no major reform enacted

Federal: FERC Cost Allocation Rules

  • The Federal Energy Regulatory Commission (FERC) has authority over interstate transmission cost allocation
  • Some proposals would require transmission projects to allocate costs to the large load customers (datacenters) that drive the need
  • Status as of 2026: Under discussion; no major rule change enacted

State Eminent Domain Reforms (General)

  • Several states have existing laws requiring premium compensation or heightened review for utility eminent domain
  • Application to datacenter-serving infrastructure is being tested through litigation and advocacy in Maryland, Pennsylvania, and Virginia
  • No state has enacted a comprehensive framework specifically requiring that datacenter-driven infrastructure costs be borne by datacenter developers rather than ratepayers or corridor landowners

Implications for Opposition Strategy

The infrastructure overspill problem has several implications for how opposition groups frame their campaigns:

  1. Expand the coalition geographically. If a datacenter in County A requires transmission lines through County B, opposition groups in County B have a direct stake in the approval decision in County A — but are not currently organized to intervene in it. Connecting these communities is an organizing opportunity.

  2. Intervene in utility commission proceedings. The transmission line approval process (state PUC/SCC) is a separate regulatory venue from the local zoning process. Opposition groups that win at the local level (blocking the datacenter) may face the infrastructure being built anyway for other load growth, while groups that lose at the local level can still fight the transmission line at the utility commission.

  3. Push for integrated review. Requiring that datacenter approvals assess and internalize the full infrastructure footprint — including off-site transmission, substation upgrades, and water impacts — would close the regulatory gap. This is a legislative/regulatory campaign target.

  4. Cost allocation as a political issue. Forcing ratepayers and remote landowners to subsidize datacenter-driven grid upgrades is politically vulnerable. The “extension cord for corporate profit” framing in Maryland resonates with rural landowners and utility watchdogs alike.
