  • 11.1MW of utility power
  • Spare 3.75 MW transformer on site
  • 250 watts/sq ft
  • Four (4) autonomous 2N power plants delivering true A & B power supply
  • Six (6) backup diesel generators on standby
  • Generators tested bi-weekly and routinely run at full load
  • Multiple voltages available including 110v, 208v, and three phase 208v
  • On-site staff constantly inspect and monitor power equipment
  • If commercial power fails, automatic transfer switches (ATS) immediately activate generators, monitor electric feeds and transfer stabilized loads to generators

Colo4 Power Infrastructure


We utilize many PDUs, ranging from 100 KVA to 300 KVA. We offer PDUs that provide branch circuit monitoring, allowing us to continuously monitor power. All the UPS systems keep equipment powered seamlessly, preventing resets while generators kick in. Our redundant feeds come from separate service entrances, ATS, generator, UPS and PDUs eliminating any single point of failure causing a customer outage.
