Frequently Asked Questions — 250kW Diesel Generator

How much does a 250kW diesel generator cost?+
A 250kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds the Cummins R-CC313D5/S (NTA855-G1B engine), rated 250 kW / 312.5 kVA prime and 275 kW / 343.8 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S4L1D-D4 or Leroy-Somer TAL-A46-G for the R-CC313D5/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-CC313D5/S price within 24 hours.
What is the fuel consumption of a 250kW diesel generator?+
At 75% load a 250kW diesel generator consumes 46.6 L/h; at 100% load it rises to 62.1 L/h. The NTA855-G1B engine in the R-CC313D5/S works out at 208.8 g/kW·h per ISO 3046-1. Actual consumption on the R-CC313D5/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 $47 per hour.
What can a 250kW diesel generator power?+
A 250kW set carries commercial and industrial building loads: hotels, schools, manufacturing plants, water and sewage pumping and commercial towers. Standby is 275 kW / 343.8 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 250kW or the next rating up fits better.
