910Telecom customers are assured of reliable, high-quality electrical power with multiple incoming commercial grids as well as generator and battery back-up. There are nine 1,000-kva transformers providing 27,758 amps at 208 volt 3-phase 4-wire. DC power (48-volt) is available with “true” A & B configuration. Tenant spaces have their own DC power plants. Four 2-Megawatt auto-start back-up generators on the roof are fueled from dedicated tanks with sufficient fuel (4,000 gallons per tank) to keep the system operating for up to 72 hours. Generators kick on within 5-15 seconds in case of power failure. Monthly tests ensure that the system is ready and functions as intended.
