ABB is deploying PowerWave33 UPS systems in Bali to support PLN, Indonesia's state-owned power company, in their preparations for this year's G20 summit. ABB's PowerWave 33 Uninterruptible Power Supply (UPS) will play a key role in guaranteeing continuous power availability to PLN's network-critical infrastructure. For maximum flexibility, PLN is deploying the ABB technology in a fleet of custom-built mobile UPS trailers or locally known as "UPS mobile", which will provide back-up power support at locations around Bali. Each mobile container integrates a complete lineup of equipment, using valve regulated lead–acid (VRLA) batteries to power the ABB Powerwave systems. ABB is supplying UPS Powerwave 33 devices with capacities ranging from 100 kVA to 250 kVA. The ABB PowerWave 33's small footprint saved space in the mobile containers, and its energy efficiency enabled
PLN to optimize the battery size, delivering significant additional savings. The PowerWave achieves efficiency of up to 96% in double conversion or 99% efficiency in eco-mode across a wide load range.
