CoreSite's Denver Data Center Ecosystem
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. Our DE2 data center, which has been operational since 2012, also is in downtown Denver. Located in close proximity to DE1 and DE2, DE3 will enable us to support increased demand for the online applications we use every day. These facilities are home to an ecosystem of more than 265 businesses, organizations, network providers and cloud providers.
Data centers that are located far from the communities they serve can create slow response times in your everyday applications. That’s why we must be close to business and population hubs, networks and cloud providers to quickly deliver information and services.
In addition to our data centers, CoreSite has been headquartered in downtown Denver for more than 20 years. We recently renewed our headquarters lease for another 11+ years, demonstrating our commitment to this city.
In CoreSite’s 20+ years in Denver, we have:
- Generated more than $5 million in tax revenue for the City and County of Denver, not including what our customers have also paid in taxes
- Invested $470 million in capital projects for our data centers and downtown headquarters
- Employed 200+ people, paying more than $32.5 million in annual wages and bonuses that support local families
- Promoted 170 employees (since 2022) to higher-paying roles through our training program
- Supported more than 450 companies and other customers in our data centers
- Contracted more than $16 million in construction spend to more than 50 different Colorado vendors
Facts About the DE3 Facility
CoreSite’s DE3 facility located at 4900 Race – at the corner of 49th Ave and Race Street – 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. It will be operational in late 2026.
Customers will likely include technology and telecommunications, education, government, e-commerce and healthcare companies.
At full build, DE3 will be approximately 170,000 square feet with 18 MW of compute power provided by Xcel Energy.
DE3 is estimated by the city’s economic development office to generate over $200 million in local sales and use taxes over 20 years, in addition to $5.5 million annually in property taxes.
Backup generators are located on the property for emergency use. The generators will periodically be tested as their maintenance requires.
The facility is expected to use on average 115,000 gallons of water daily, supplied by Denver Water. We recirculate and reuse water for cooling whenever possible and most of the water used in cooling – about 75% – evaporates and returns to the natural water cycle in the form of precipitation.
Prior State of DE3 Property
Before CoreSite began development of our DE3 facility on this property located at the corner of 49th Avenue and Race Street in the Elyria-Swansea neighborhood, it operated as a concrete plant.
Remediation Efforts
CoreSite spent nearly five months removing asbestos from the site. In total, CoreSite removed 2,454 cubic yards of landfill containing asbestos – enough material to fill 175 dump trucks.
CoreSite invested nearly $743,000 to clean up the soil at the site, reducing the risk of harmful fibers becoming airborne.
Site Improvements
As part of our redevelopment efforts, we will implement significant site improvements designed to enhance both the property and the surrounding community.
These improvements include:
- New green spaces, play areas and picnic tables to create welcoming community gathering spaces
- 75 trees and more than 30,000 shrubs to support urban beautification and environmental sustainability
- New, wider sidewalks to improve pedestrian safety and accessibility
- Upgrade fiber infrastructure to enhance connectivity and expand high-speed service capabilities for the Globeville Elyria-Swansea (GES) neighborhood
Globeville Elyria-Swansea Neighborhood
Community input and engagement is important to us and has been throughout our 20+ year presence in Denver.
Specific to our DE3 project, we have:
- Hosted two public community meetings and a job fair
- Met with community organizations, including the GES Coalition, many times to gather their feedback and hear their concerns
- Answered multiple rounds of questions in writing
- Hosted tours of our facilities with the mayor and city council members
- Volunteered with local organizations like Focus Point and with Extreme Community Makeover for a Swansea neighborhood cleanup
- Donated to the Jack A. Vickers Boys and Girls Club to create a new digital community
- Donated to the Swansea Recreation Center to build a new game room
This important engagement will continue. In fact, for the better part of 2026, we’ve been exploring a Good Neighbor Agreement with the GES community – a process our team voluntarily initiated to foster a constructive conversation with the community. We're continuing to work with the community and its leaders to ensure their voices are heard.
