20KVA / 18KW Industrial Backup Uninterruptable Power Supply (UPS) to replace the existing Gaseous Effluent Monitoring System (GEMS) UPS at the LaSalle Nuclear Generating Station. The UPS is required to be a double conversion, 3Ø, 208/120V AC, 4 Wire + Gnd, Wye Input / 3Ø, 208/120V AC, 4 Wire + Gnd, Wye Output. The successful vendor is required to be manufacturer certified to perform initial startup/commission and have the ability to perform initial startup on-site at the LaSalle Nuclear Generating Station. IEMA personnel will perform equipment installation at the LaSalle Nuclear Generating Station. Vendor will perform initial startup once installation is complete
