The installation of generators is the most common solution for backup power. While the modern generator is highly reliable, the use of multiple generators for critical applications offers the ability to provide redundancy to allow for maintenance or failure. Moreover, paralleling systems provide the capability to increase total capacity while also ensuring uninterrupted backup power protection during maintenance or the failure of a single generator.

Furthermore, since many weather-related power outages are far more widespread, this typically impacts the time to restore the utility power infrastructure. Therefore, intelligent power management systems, which are the nexus of a paralleling system, should also be able to optimize resources while on backup generator power to meet varying load demands. This can help increase fuel runtime autonomy while still ensuring uninterrupted power to the most critical loads.
