About
CoreSite DE1 is a 152,000-square-foot carrier-neutral colocation data center located at 910 15th St. in downtown Denver, CO — the highest network-density commercial facility in the Rocky Mountain region. For facility managers and property owners overseeing mission-critical infrastructure in Denver, DE1 represents the standard for large-scale commercial electrical and power distribution design. The facility supports complex three-phase power distribution, redundant UPS systems, and large-capacity backup generator infrastructure required to sustain continuous uptime for performance-sensitive tenants. DE1's electrical backbone supports over 150 interconnected networks and delivers metro Ethernet connections up to 100G, with dark fiber tethering to CoreSite's second Denver campus, DE2. These interconnection demands drive robust low-voltage, data cabling, and power quality systems throughout the facility — the same critical system types that commercial electrical contractors service across Denver's office towers, healthcare campuses, government buildings, and institutional properties. The facility houses cloud providers, financial services firms, healthcare networks, and government tenants, all requiring precisely engineered panelboard and switchgear configurations to meet NEC commercial code compliance. Facility managers evaluating electrical contractors for comparable Denver commercial properties — from Class A office buildings to mixed-use institutional campuses — can benchmark their power distribution, generator, and UPS requirements against the operational standards CoreSite DE1 maintains. Its multi-site connectivity model, spanning 11 edge markets nationally, also illustrates the multi-site coverage expectations that building owners and general contractors increasingly demand from their electrical service partners. DE1's scale and criticality make it a benchmark reference point for commercial electrical infrastructure excellence in the Denver metro market.
