Generator sets are typically sized for peak load. However, most of the time they run at low load factors which results in poor fuel economy & high emissions. By connecting PUNCH Flybrid technology to the generator set the flywheel will load level the peak loads that the generator set has to deal with. The PUNCH Flybrid system delivers energy immediately at high power during an increasing load step and captures excess energy during a decreasing load step. This results in smooth, consistent and controlled generator loading which facilitates diesel to gas substitution, downsizing and engine operating efficiency improvements.
