Frequently Asked Questions — 300kW Diesel Generator

How much does a 300kW diesel generator cost?+
A 300kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds the Cummins R-CC375D5/S (NTAA855-G7 engine), rated 300 kW / 375 kVA prime and 330 kW / 412.5 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S4L1D-F4 or Leroy-Somer TAL-A473-A for the R-CC375D5/S), the controller and options such as ATS, and with the destination country and freight terms. Send your voltage, frequency and destination country and we will confirm the R-CC375D5/S price within 24 hours.
What is the fuel consumption of a 300kW diesel generator?+
At 75% load a 300kW diesel generator consumes 55.4 L/h; at 100% load it rises to 73.8 L/h. The NTAA855-G7 engine in the R-CC375D5/S works out at 206.7 g/kW·h per ISO 3046-1. Actual consumption on the R-CC375D5/S varies about ±5% with ambient conditions, load profile and fuel quality. At a diesel price of $1.0/L, running at 75% load costs roughly $55 per hour.
What can a 300kW diesel generator power?+
A 300kW set powers heavy commercial and industrial facilities: hospitals, manufacturing plants, commercial buildings, cold storage and mid-size data centers. Standby is 330 kW / 412.5 kVA, which leaves starting margin for motor loads on top of the base load. Tell us your connected load and the largest motor you need to start and we will confirm whether 300kW or the next rating up fits better.
