A new data-center, slated for completion in 2025, is planned to become the nexus of networks in the Rocky Mountain region. CoreSite, a subsidiary of American Tower, has partnered with Stonespeak Opportunities Fund to bring a 60-megwatt data center to Denver.

In this initiative to accelerate digitization, Stonespeak currently holds an 85% equity stake in the project, which will be operated by CoreSite.

‍
CoreSite was acquired by American Tower, a company traditionally focused on owning cell towers, for $10.1 billion in November 2021 to expand its footprint in the technology sector. Stonespeak acquired 29% of CoreSite for $2.5 billion the following year.

Alongside a suite of other digital infrastructure investments such as Digital Edge, LATAM firm Cirion, and Guam telco, CoreSite's 28 facilities across 11 U.S. markets will complement the firm's overall market strategy.The first building on the campus (DE3) will be a 97,000-square-foot facility with 18 Compartmented Mode Workstations (CMWs), and a total of 322,000 square feet on a 15.1-acre site, using 6 megawatts with 60 CMWs planned.

The three-story building will primarily house the data center and related facilities on the first level, while floors two and three will offer leasable tenant space.The initial DE3 building is targeted for completion in 2025 at the intersection of 4900 N Race and E 49th Street. However, this is just the beginning of the CoreSite and Stonespeak partnership.

The DE3 building will exist alongside CoreSite's current data centers, DE1 on 15th Street and the DE2 building on 18th Avenue, all linked via high-speed fiber internet to serve as carrier interconnection hubs, further positioning Denver as a tech hot spot.

Plans for the DE3 building mirror those of other data centers with a strong emphasis on security.

Unlike other centers under the CoreSite banner, DE3 will not have a stand-alone substation but will instead house primary electrical distribution rooms on each floor, equipped with an uninterruptible power supply (UPS) to support the massive power requirements.

CoreSite plans to provide ample parking for both vehicles and bicycles, with spaces facing out onto North Race Street. The parking area will include EV charging stations, and an open space on the right side of the building will bring Denver’s signature outdoor emphasis, contrasting with the security measures necessary for operating a data center.

The project includes a stormwater basin integrated into the open space on the premises to help filter potential pollutants, either reusing them in the cooling system of the data center or releasing the water through proper drainage in an environmentally sustainable manner.

Alongside the basin, the planned DE3 building will feature water-chilled coolers, cooling towers, water storage tanks, and diesel-powered generators to ensure the uptime of all computing assets.

Security measures for the project include perimeter fencing, extensive CCTV coverage, and man traps for access control.

These precautions are designed to meet future compliance requirements associated with operating a data center in the densely populated area of North Denver.
