Ridgetop Center Data Center 21670 Ridgetop Circle Sterling VA AWS

Status: Proposed / Redevelopment Permitting & Demolition Phase   |   Location: 21670 Ridgetop Circle, Sterling, VA 20166, USA

Project Overview

The Ridgetop Center Data Center, also designated as the AWS Ridgetop Circle Campus, is a proposed hyperscale data center redevelopment planned on an approximately 11.8-acre site centered around 21670 Ridgetop Circle, Sterling, Loudoun County, Virginia 20166, USA, encompassing the properties at 21660, 21670, and 21680 Ridgetop Circle. Developed by Amazon Data Services, Inc., the project involves the redevelopment of an existing commercial property within the Loudoun Tech Center business park, with plans to demolish three existing low-rise office buildings and replace them with two purpose-built, multi-story hyperscale data center facilities. The proposed buildings are expected to provide a combined floor area of approximately 268,339 to 300,000 square feet, creating a substantial new computing footprint within one of Northern Virginia's most established digital infrastructure markets. Located directly off Route 28 North in the Sterling/Dulles technology corridor, the project benefits from proximity to existing data centers, major telecommunications networks, power infrastructure, and a mature technology ecosystem. The development is expected to expand Amazon Web Services' local availability zone footprint and provide additional capacity for cloud computing, artificial intelligence, machine learning, and high-density inference workloads. The campus is planned with an estimated critical IT capacity ranging from approximately 36.0 MW to 50.0 MW, requiring significant electrical infrastructure to support computing equipment, cooling systems, backup systems, and other mission-critical operations. Power is expected to be supplied through direct interconnections with Dominion Energy's regional subtransmission grid, providing access to the electrical infrastructure necessary for reliable continuous operation. The redevelopment also represents a broader trend in Northern Virginia toward converting underutilized commercial properties into high-value digital infrastructure assets. With its strategic location, multi-story hyperscale configuration, substantial planned IT capacity, and integration into AWS's regional infrastructure network, the Ridgetop Center Data Center represents a significant addition to the continuing expansion of cloud and AI computing capacity in the Sterling/Dulles market.
