CoreSite, an American Tower company, has acquired the Denver Gas and Electric Building at 910 15th Street, expanding its data center presence in the Rocky Mountain region’s most network-dense facility. The building currently hosts CoreSite’s DE1 data center and serves as Denver’s primary carrier hotel. With this transaction, CoreSite plans to add approximately 3 critical megawatts (CMW) of data center capacity, nearly doubling DE1’s space and power footprint to support growing demand from public cloud platforms, enterprises, and network providers.
The acquisition enhances customer access to Google Cloud Platform’s Dedicated Interconnect onramp and strengthens CoreSite’s Any2Denver Exchange, a key peering hub in the region. It also brings roughly 100 interconnection-focused tenants into CoreSite’s ecosystem. By owning the facility outright, CoreSite can streamline infrastructure upgrades to better support high-performance, latency-sensitive applications and future AI workloads.
The Denver campus now includes DE1 and DE2, and is expanding with the construction of DE3—a new enterprise-grade facility at 4900 N. Race Street. Once completed, DE3 will provide 97,000 square feet of space and 18 CMW of capacity. These combined assets solidify CoreSite’s position as Denver’s leading interconnection platform, delivering high-density, cloud-enabled infrastructure for regional and national customers.
