Overview#
The Cummins C2000 N6c is a 2000 kW (2500 kVA) standby natural gas generator set powered by the HSK78G -- a 78-liter, turbocharged and aftercooled spark-ignited gas engine at its maximum standby rating. The HSK78G is Cummins' flagship gas engine, purpose-built for high-capacity gas applications (not a diesel conversion). At 2 MW, the C2000 N6c is the largest single-unit natural gas generator in the Cummins product line.
The C2000 N6c serves the most demanding standby applications: large hospital campuses, hyperscale data centers, major institutional campuses, and heavy industrial facilities. For installations requiring more than 2 MW of gas-fired backup, multiple C2000 N6c units can be paralleled. The unit runs on natural gas or propane vapor and is equipped with PowerCommand controls.

Our Service Experience#
The HSK78G at the 2000 kW rating represents the top of the Cummins gas generator lineup. This is a purpose-built gas engine -- not derived from a diesel platform -- which gives it combustion efficiency and emissions advantages. Service requires factory-trained technicians with HSK78G-specific experience and tooling. Spark plug replacement is a significant planned maintenance event requiring scheduling and coordination.
Gas supply infrastructure at 2 MW is a major engineering project. At approximately 20,000 CFH, the facility requires utility-grade gas service with dedicated industrial metering, 6-inch or larger supply piping, and industrial-grade pressure regulation rated for the full demand. Gas utility coordination is essential during early project planning -- service upgrades at this capacity level typically require months of lead time.
The catalytic converter (where fitted for emissions compliance) is a critical maintenance item at 2 MW. Backpressure monitoring should be performed at every scheduled service interval. Catalyst degradation at this power level can result in significant derating and, in jurisdictions with strict emissions requirements, compliance issues.
