Running Utilities to Data Centers: The Real Property Perspective

In 2026, the data center development equation has fundamentally shifted. The limiting factor is no longer land availability, fiber connectivity, or even capital — it's power. The ability to deliver reliable electricity to a site at the scale and timeline a hyperscaler requires has become the dominant filter in site selection and the primary driver of land value in data center corridors.

For real property professionals, this creates both complexity and opportunity. Understanding how utilities reach a data center site — the easements, rights-of-way, interconnection processes, and infrastructure investments required — is now essential knowledge for anyone acquiring, developing, or financing data center real estate.

The Scale of Power Requirements

Data center power requirements dwarf most other commercial real estate uses:

• Edge/Colocation Facilities: 1-30 MW

• Enterprise Data Centers: 30-100 MW

• Hyperscale Campuses: 100-500+ MW

• AI/GPU-Intensive Facilities: 200+ MW and growing

For context, a typical 100,000 SF office building might draw 2-3 MW at peak. A single hyperscale data center can require the equivalent power of a small city. This scale fundamentally changes how developers think about utility infrastructure — it's not a service you order from the utility, it's a partnership you negotiate and often co-invest in.

Transmission vs. Distribution: The Infrastructure Hierarchy

Understanding the utility infrastructure hierarchy is essential for evaluating data center sites:

Transmission Infrastructure

High-voltage transmission lines (345 kV, 230 kV, 138 kV) carry bulk power from generation sources to substations. For hyperscale loads, proximity to transmission infrastructure is non-negotiable:

• 345 kV lines: Required for 100+ MW loads; typically within 5-10 miles of site

• 230 kV lines: Suitable for 50-100 MW; proximity within 3-5 miles preferred

• 138 kV lines: Adequate for smaller facilities; closer proximity required

Substations

Substations step down transmission voltage to distribution levels. A hyperscale data center typically requires:

• A dedicated substation or exclusive access to substation capacity

• Multiple independent feeds for redundancy (N+1 or 2N configurations)

• Expansion capacity for phased development

Substation construction — whether utility-owned or developer-built — is often the longest lead-time item in data center development, ranging from 24-48 months depending on permitting and equipment procurement.

Distribution Infrastructure

Distribution lines (typically 12-35 kV) carry power from substations to end users. For large data centers, the distribution network is usually purpose-built from the substation to the facility.

The Real Property Framework: Easements and Rights-of-Way

Getting power to a data center site requires assembling a real property package that extends well beyond the development parcel itself.

Utility Easements

Easements grant utilities the legal right to construct, operate, and maintain infrastructure across private property. Key considerations:

• Width: Transmission easements typically range from 100-200 feet wide; distribution easements are narrower (20-50 feet)

• Restrictions: Easement terms restrict what the landowner can do within the easement area — no structures, limited vegetation, no interference with access

• Perpetuity: Utility easements generally run with the land in perpetuity and survive property transfers

• Compensation: Landowners receive one-time payments for easement grants, typically based on land value and impact to remaining property

Rights-of-Way

Rights-of-way (ROW) are similar to easements but often apply to public land or dedicated corridors. For transmission projects:

• Public ROW along highways and rail corridors is often preferred to minimize private land acquisition

• Municipal and county approvals are required for ROW use

• Environmental review (NEPA/SEPA) may apply if federal or state land is involved

Fee Simple Acquisition

In some cases, utilities or developers purchase land outright rather than acquiring easements:

• Substation Sites: Typically acquired in fee simple (2-10 acres depending on voltage and configuration)

• Switching Stations: Smaller parcels for utility control equipment

• Generation Sites: If on-site power generation is included (natural gas, solar, battery storage)

Condemnation and Eminent Domain

If voluntary easement acquisition fails, utilities with regulatory authority can exercise eminent domain to acquire necessary rights. This is a last resort that adds time and cost, but it provides a backstop for critical infrastructure projects.

The Interconnection Process

Connecting a large load to the grid is not a simple application — it's a multi-year regulatory and engineering process.

Regional Transmission Organizations (RTOs)

Most of the U.S. is covered by RTOs that manage the transmission grid:

• PJM: Mid-Atlantic and parts of Midwest (Northern Virginia, Chicago)

• ERCOT: Texas (Dallas, Austin, San Antonio)

• MISO: Midwest and South

• CAISO: California

• SPP: Central U.S.

Each RTO has its own interconnection study process, queue management, and cost allocation methodology.

Interconnection Queue

Large loads enter an interconnection queue for study by the RTO and affected utilities:

• Feasibility Study: Initial screening of grid impact (3-6 months)

• System Impact Study: Detailed analysis of required upgrades (6-12 months)

• Facilities Study: Engineering and cost estimates for interconnection facilities (6-12 months)

• Interconnection Agreement: Binding contract specifying costs, timeline, and responsibilities

In congested markets, the interconnection queue has become the primary bottleneck. PJM's queue backlog has reached multi-year timelines, with some positions taking 36-48 months just to complete studies — before any construction begins.

Network Upgrades

The interconnection study often identifies required network upgrades — improvements to the existing grid necessary to accommodate the new load:

• Transmission line upgrades: Reconductoring, new circuits, or new lines

• Substation upgrades: Additional transformers, switchgear, or protection systems

• Cost responsibility: Data center developers typically pay for network upgrades, with partial refunds over time if other users benefit

Network upgrade costs can range from $10 million for minor improvements to $100+ million for major transmission projects. These costs are increasingly factored into land basis and site selection decisions.

Water and Cooling Infrastructure

Power is the primary utility, but water infrastructure is also critical for data center operations.

Cooling Water Requirements

• Traditional Data Centers: ~500,000 gallons/day for evaporative cooling

• AI/GPU-Intensive Facilities: 1-2+ million gallons/day

• Liquid-Cooled Facilities: Lower water consumption but higher upfront infrastructure cost

Water Rights and Access

In water-stressed regions (Phoenix, parts of Texas, California), water access is becoming a site selection filter:

• Municipal Water: Capacity confirmation required; may require infrastructure extensions

• Well Water: Requires water rights verification and permitting

• Recycled Water: Increasingly used for cooling; requires separate infrastructure

• Discharge Permits: Required for cooling water discharge; can add permitting time

Fiber Connectivity

While power is the constraint, fiber connectivity remains essential:

• Diverse Routes: Multiple fiber paths from different directions for redundancy

• Carrier Neutrality: Access to multiple network providers

• Dark Fiber: Unlit fiber available for tenant-specific high-bandwidth needs

• Latency: Proximity to internet exchange points (IXPs) and major population centers

Fiber easements are typically narrower than power easements (10-20 feet) and can often share corridors with power infrastructure.

Site Selection: The Real Property Checklist

For developers evaluating data center sites, utility infrastructure due diligence should address:

Power

• Transmission line proximity and voltage (345 kV, 230 kV, 138 kV)

• Existing substation capacity and expansion potential

• Utility load availability letter (MW, timeline, preliminary cost)

• Interconnection queue position (if applicable)

• Estimated time to energize

• Required easements/ROW for power delivery

• Estimated network upgrade costs

Water

• Municipal water capacity confirmation

• Water rights (if well water)

• Required infrastructure extensions

• Discharge permit requirements

Fiber

• Fiber route proximity and diversity

• Carrier presence and neutrality

• Dark fiber availability

• Required easements for fiber extension

Easement Package

• Existing easements on target parcel (title review)

• Required new easements for utility delivery

• Third-party parcel impacts and acquisition strategy

• Utility company cooperation and timeline

On-Site Power: The Emerging Trend

Grid constraints are pushing developers toward on-site power generation:

• Natural Gas Generation: On-site gas turbines or reciprocating engines

• Solar + Storage: Increasingly viable for partial load, with battery backup

• Fuel Cells: Clean generation option, particularly for sustainability-focused operators

• Direct Utility Bypass: Some developers are negotiating direct gas supply and building dedicated generation facilities

On-site generation introduces additional real property considerations:

• Gas pipeline easements and interconnection

• Generation facility permitting (air quality, noise, environmental)

• Fuel storage and delivery infrastructure

• Backup grid connection for redundancy

The Bottom Line

Data center development has become as much about utility infrastructure as it is about real estate. The ability to deliver power — at scale, on timeline, and at competitive cost — is now the primary determinant of site viability and land value.

For real property professionals, this means understanding a new vocabulary: interconnection queues, network upgrades, transmission easements, and time to energize. It means evaluating not just the parcel, but the infrastructure corridor required to serve it. And it means recognizing that in data center development, the utility package is often worth more than the land itself.

The developers who succeed in this market will be those who can assemble the complete real property package — land, easements, rights-of-way, and utility commitments — before their competitors. In a power-constrained environment, site control without power certainty is not site control at all.
