1 SHOULDER TO SHOULDER The case for paralleling generator sets

2 Your operation. Your decision. Cat expertise. Your Cat Dealer knows when multiple units make more sense than one. Power systems requirements are changing in the digital age. The growing need for clean, reliable power for critical loads can quickly outpace a facility s system. In today s world, facility managers have to design flexibility and reliability into their electric systems and plan for future growth and expansions. Trust your Cat Dealer to provide the knowledge and support you ll need to handle any power challenge, from the simplest backup to the most complex integrated systems.

3 Scaling for Growth When you identify potential growth on site, your options are limited unless you ve planned for it. Installing a smaller unit now and adding an extra unit when it is needed allows you and your Cat Dealer more flexibility in tackling those challenges. If the variation in load demand between peak demand and off-peak is great, then the ability to drop units off-line will help optimize your fuel consumption, giving you more available hours of operation for your tank size. With a parallel system, you ll have the choice between simple, advanced and custom methods to integrate units that meet your expansion needs. Critical Load and Redundancy Using multiple small units to cover the total peak power demand can allow for critical load redundancy, maximizing your operation s efficiency.

4 Keep your project moving Using paralleled multiple units gives you more flexibility in sourcing the size of standard generator sets, which may be more readily available than larger custom systems. This means faster turnaround time so you get the power distribution portion of your project done sooner.
