The new mtu Series 4000 G05 generator set from Rolls-Royce provides a fully integrated power solution that features direct coupling of the engine and aftertreatment for a smart system from a single source that can optimize emissions performance. It features a 12-V configuration and comes in four ratings for 60 Hz standby applications: 1350 kWe, 1500 kWe, 1600 kWe, and 1750 kWe.

The aftertreatment system consists of a diesel oxidation catalyst, diesel particulate filter, and selective catalytic reduction system. It was jointly developed with the Series 4000 G05 engine so that the two work seamlessly together. The plug-and-play design of the generator set and aftertreatment system simplifies the design and specification for the emergency power system within the overall project.
