Amendment 0008 Attachment 11692148.pdf

This is a technical specification document for a Power Generation Microgrid system at Cape Cod Space Force Station in Bourne, Massachusetts. The document outlines detailed requirements for an Uninterruptible Power Supply (UPS) system designed to support critical operations at the facility.

The UPS system specifications include scalable power modules rated at 400 or 500 kVA, configured to handle a total system load of 2000 kVA and 2000 kW. The battery system must deliver a five-minute discharge time to end voltage at 77 degrees Fahrenheit while providing 100 percent of full rated UPS kilowatt load at 0.9 power factor during initial startup. The static switch requires a continuous duty rating of 2500 amperes, and the system must withstand short circuit conditions of at least 65,000 amperes symmetrical interrupting capacity. AC input specifications require 480 volts three-phase plus ground configuration with a voltage range of plus 10 percent to minus 20 percent nominal, 60 Hertz frequency (±5 percent), and a one-to-30 second variable power walk-in set to 10 seconds. AC output must maintain 480 volts three-phase plus ground configuration with voltage regulation requirements. Additional requirements include total harmonic current distortion not exceeding 5 percent at full load, input surge protection per IEEE C62.41.1 and C62.41.2 standards, and input power factor greater than 0.98 lagging.
