National Data Center West

Centennial, CO

In the summer of 2012, Time Warner Cable (TWC) began the development of a new National Data Center in Colorado to support their critical operations in the western portion of the US. This three-story greenfield data center project was completed in December 2014 with the first Data Hall going live in January 2015.

This facility houses four Data Halls on a total of 70,000-square-feet of raised floor, designed to support 1600 kW each (6,400 kW total IT load). Infrastructure for the Data Center was developed to satisfy Concurrent Maintainability (Tier III), while still achieving a rating of LEED Gold by the USGBC.

  • Critical Power Distribution: Six (6) 3MW diesel EGs in an N+1 configuration. The plant is sized to carry the entire building at full load (approximately 12 MW). UPS Architecture includes 3(N)/2 UPS configuration with a total of (12) 900 kW Modules for a peak usable output of 7,200 kW (6,480 kW at 90% redline).
  • Chiller Plant: The mechanical plant was designed to take advantage of the local climate, relying primarily on evaporative cooling, the facility will operate in the “free cooling mode” for approximately 80% of the year. The plant consists of (6) 550-ton fluid coolers in series with air-cooled chillers (to provide the supplemental cooling required during the summer in periods of high wet bulb ambient conditions). The chillers are sized to provide 100% plant capacity in case of a loss of municipal water supply.
  • Continuous Cooling: A pair of Mechanical UPS Modules serves the CRAH fans, CHW pumps, and BAS to provide continuous cooling (in conjunction with 60,000 gallons of CHW storage).
  • Data Halls: Each of the (4) Data Halls can support 1,600 kW of IT load on a 36” deep raised access floor. Dual power cord technology IT Equipment is arranged in a hot aisle / cold aisle configuration, with a floor density of 100 watts / SF and an average rack density of 5kW. Downflow CHW units and PDUs are located in dedicated equipment galleries, minimizing the need for facility personnel to access the Data Halls.
