CoreSite's Denver Data Center Ecosystem
CoreSite’s DE3 data center will be approximately 170,000 square feet and 18 MW, with operations scheduled for June 2026. CoreSite’s current Denver market footprint includes the historic Denver Gas and Electric Building, the most interconnected building in the Rocky Mountain region, which has housed our DE1 data center for over a decade. Located in close proximity, DE3 will enable us to support increased demand for the cloud applications we use every day. These facilities are home to an ecosystem of more than 265 businesses, organizations, network providers and cloud providers.
DE3 is located at 4900 Race Street in Denver and will bring benefits to the local community by creating new jobs, supporting regional businesses with reliable digital infrastructure, attracting technology investment and strengthening the area’s overall economic growth through improved connectivity and access to modern IT resources.
Prior State of DE3 Property
Before CoreSite began development of our DE3 facility on this heavy-industrial-zoned property located at the corner of 49th Avenue and Race Street in the Elyria-Swansea neighborhood, it operated as a concrete plant.
As part of our redevelopment efforts, we will implement significant site improvements designed to enhance both the property and the surrounding community. These improvements will include the addition of new green spaces, play areas, and picnic tables to create welcoming community gathering spaces. We will plant 75 trees and more than 3,000 shrubs to support urban beautification and environmental sustainability. The project will also include the construction of new, wider sidewalks to improve pedestrian safety and accessibility, as well as upgraded fiber infrastructure to enhance connectivity and expand high-speed service capabilities within the Elyria-Swansea neighborhood.
Facts About the DE3 Facility
CoreSite’s DE3 data center will be approximately 170,00 square feet with 18 MW.
CoreSite’s new Denver DE3 data center campus is estimated by the city’s economic-development office to generate “over $200 million in incremental local tax revenue” over a 20-year period from the project and its customers.
We have hired approximately 175 construction workers over a 24-month period to build our DE3 data center, and as many as 250 at its peak.
CoreSite is funding the development of a new on-site substation so that the data center does not impact the power available to the neighborhood.
Emergency backup generators are located on the property for emergency use. The generators will periodically be tested as their maintenance requires, which is less than 50 hours per year.
The facility is expected to use ~13gal/kW/day. CoreSite follows best practices and best-in-class building design. We recirculate and reuse water for cooling whenever possible.
CoreSite is investing in the land development of the DE3 site, including creating new sidewalks, street frontage, lighting, bike lanes and landscaping such as 75 trees, 3,000 shrubs and grass, as shown in the image below.
