data center alley

Data Center Alley represents the world’s largest concentration of datacenter infrastructure, centered in Northern Virginia with extensions into Maryland. This region has evolved into the dominant global hub for internet infrastructure, cloud computing, and hyperscale operations.

overview

geographic scope

Primary States

• Virginia (40 projects)
• Maryland (8 projects)

Key Metro Areas

• Ashburn (12 projects) - epicenter of global internet infrastructure
• Adamstown, MD (5 projects) - emerging Maryland cluster
• Loudoun County (concentrated development)
• Prince William County (major expansion zone)
• Central Virginia (AWS rural expansion)

historical development

early foundations

Data Center Alley emerged in the late 1990s and early 2000s as the internet backbone coalesced around Northern Virginia. The region’s advantages included:

• Proximity to Washington DC and federal government
• MAE-East internet exchange point in Tysons Corner
• Abundant fiber optic infrastructure
• Available land and power in Loudoun County
• Tax incentives and supportive local government

hyperscale evolution

The 2010s saw explosive growth as cloud providers (AWS, Microsoft Azure, Google Cloud) established major regional presences. AWS’s deep roots in the region (headquartered in Arlington, VA) made Northern Virginia the flagship US-East region for AWS services.

current saturation

By the 2020s, Loudoun County alone hosted over 25 million square feet of datacenter space, consuming over 2.5 GW of power. This concentration has led to:

• Infrastructure constraints (power grid capacity)
• Community opposition to further development
• Geographic expansion into adjacent counties
• Rural Virginia development (Louisa, Culpeper, Spotsylvania counties)

network connectivity

internet exchange points

Data Center Alley hosts critical internet infrastructure:

• Equinix DC metro - one of the largest US peering ecosystems
• MAREA cable - transatlantic subsea cable to Spain terminating in Virginia Beach
• BRUSA cable - Brazil to USA subsea cable terminating in Virginia Beach
• Both cables connect to QTS Richmond creating a major network access point

fiber infrastructure

The region benefits from dense fiber networks including:

• Multiple diverse fiber routes from Washington DC
• Direct connectivity to internet exchange points
• Low-latency paths to New York financial markets
• Redundant paths to other major US markets

power infrastructure

grid capacity

Dominion Energy serves the region with substantial generation capacity:

• 13.2 GW total datacenter capacity across projects
• Multiple 230kV and 500kV transmission lines
• Continuous grid upgrades to meet demand
• Growing strain on capacity requiring new generation

power constraints

The rapid growth has created challenges:

• Multi-year wait times for new power allocations
• Need for on-site substations for large projects
• Competition for limited capacity
• Grid reliability concerns during peak demand

renewable energy

Major cloud providers have commitments to renewable energy:

• AWS: 100% renewable energy commitment, enabling 700+ MW of Virginia solar
• Google: renewable energy matching for all operations
• Meta: 100% renewable energy for Virginia facilities
• Microsoft: substantial solar and wind power purchase agreements
