Overview#

The Cummins C2000 D6e is a 2000 kW (2 MW) standby diesel generator set from the Centum Series, launched in 2024. Powered by the QSK50 diesel engine at its peak output within the Centum platform, the C2000 D6e delivers multi-megawatt standby power with the Centum's signature smaller footprint, charged air-cooled intake, and PowerCommand 3.3 controller.

The 2 MW class is the most commonly specified building block for large data center standby arrays. The Centum C2000 D6e competes directly with the traditional C2000 D6 (QSK60 platform), offering a more compact package with tighter Cummins integration. The QSK50 achieves 2000 kW with less displacement than the QSK60, enabled by the Centum platform's advanced air management system.

PowerCommand 3.3 provides advanced paralleling, load management, and BMS integration via Modbus, BACnet, and SNMP. Medium-voltage output options (4160V, 12470V, 13800V) support utility-grade paralleling bus architectures. Five C2000 D6e units in a paralleling array deliver 10 MW of standby capacity with N+1 redundancy. Fuel consumption runs approximately 140 gallons per hour at full rated load.

Frequently Asked Questions

When was the C2000 D6e launched?
The C2000 D6e was launched in 2024 as part of Cummins' Centum Series expansion. It delivers 2 MW standby from the QSK50 engine platform within the Centum's compact, premium footprint.
What engine does the C2000 D6e use?
The C2000 D6e uses the Cummins QSK50 diesel engine with MCRS fuel injection. At 2000 kW, this is the top of the QSK50 power band within the Centum Series platform.
What are the standby and prime ratings of the C2000 D6e?
Standby rating is 2000 kW (2500 kVA) at 60 Hz, 0.8 power factor. Prime rating is 1820 kW (2275 kVA). Both at 1800 rpm, 60 Hz, three-phase.
How does the Centum C2000 D6e differ from the standard C2000 D6?
Both deliver 2000 kW standby, but the Centum C2000 D6e uses the QSK50 engine in a compact platform with charged air-cooled intake and the PowerCommand 3.3 controller. The standard C2000 D6 uses the QSK60 (60L) engine in the traditional D6 platform. The Centum offers a smaller footprint and tighter integration for data center applications.
Can PowerGen service the C2000 D6e in Northern California?
Yes. PowerGen provides authorized Cummins service for Centum Series generators across the San Francisco Bay Area and Northern California. The Centum platform uses standard Cummins engines and components, serviced with INSITE diagnostics by our factory-trained technicians.
