Some jobs require more energy than a single generator can provide. At other jobsites, the amount of power needed fluctuates throughout the workday. More contractors are paralleling generators to achieve power needs or adjust energy output for different jobs while keeping the cost of operations low.
Additional money savings comes with the other benefit of paralleling: uninterrupted power output. When operators rely on a single, multi-megawatt generator for an entire operation, they are putting their eggs in one basket. Maintenance operations will shut down all power at a site. When multiple generators are paralleled, a single generator can be shut down, preventing downtime and saving money.
The number of sites paralleling generators continues to grow in the U.S. as contractors see the efficiency and cost-saving benefits it provides.
1.  Reliability: Even if one generator fails, you’ll know you have back-up power, especially for the most critical loads.
2.  Expandability: Effortlessly increase and decrease your output based on changing power needs.
3.  Ease of maintenance and serviceability: Diesel technicians can service each generator individually. This allows you to take one smaller generator offline at a time, rather than pulling the   entire power source, ensuring your jobsite continues to run.
4.  Cost savings: Paralleled generators respond to changing loads, meaning less fuel is used and fewer hours are put on the machines since the generators only run when needed.  
The easiest way to parallel generators is to have multiple models of the same generator or generators with matching output ratings and alternator pitches. You’ll also need a controller that can create a power management system. Then, there are just three easy steps to get powered:
1.  Connect the genset output power cables to a common bus, and the single communication cable to each genset.
2.  Set the control parameters for the optimal Power Management System you wish to use.
3.  Push the start button on one of the gensets.
After hitting start, generators start, automatically synchronize and connect in parallel. The system can be set up to automatically adjust to varying power demands throughout the day, greatly increasing system efficiency. The more efficiently your system operates, the more time and money you can save. Click here to learn more about our other generators.
