The Cat® PGS Module is a scalable, rapidly deployable energy storage system. The PGS integrates with solar or other renewable sources to provide short duration power when the renewable source is not available or virtual spinning reserve to optimize generator sets efficiency. This system provides temporary backup power to facilities in the event of a power outage.
