1000kW Diesel Generator Set

Q: How much does a 1000kW diesel generator cost?

A 1000kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds 4 engine platforms (Cummins R-CC1250D5/S, Perkins R-P1250D5/S, MTU R-M1250D5/S, Mitsubishi R-JM1250D5/S), rated 1000 kW / 1250 kVA prime and 1100 kW / 1375 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S6L1D-G4 or Leroy-Somer LSA 50.2 M6 for the R-CC1250D5/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-CC1250D5/S / R-P1250D5/S / R-M1250D5/S / R-JM1250D5/S price within 24 hours.

Q: What is the fuel consumption of a 1000kW diesel generator?

Fuel consumption for a 1000kW diesel generator is 177.7-197.3 L/h at 75% load and 236.9-263.1 L/h at 100% load across the 4 platforms: Cummins R-CC1250D5/S 188.4 / 251.2 L/h; Perkins R-P1250D5/S 183.0 / 244.0 L/h; MTU R-M1250D5/S 177.7 / 236.9 L/h; Mitsubishi R-JM1250D5/S 197.3 / 263.1 L/h. Measured efficiency is 199-221 g/kW·h per ISO 3046-1, and actual consumption varies about ±5% with ambient conditions, load profile and fuel quality. At a diesel price of $1.0/L, 75% load costs roughly $178-197 per hour.

Q: What can a 1000kW diesel generator power?

A 1000kW set serves large industrial and data-center sites: data centers, large hospitals, mining and mid-to-large manufacturing. At this rating Cummins, Perkins, MTU and Mitsubishi are available, so the same 1100 kW / 1375 kVA standby rating can be specified on any of them. Tell us your connected load and the largest motor you need to start and we will confirm whether 1000kW or the next rating up fits better.

Q: Which engine brands and configurations are available for a 1000kW generator?

The 1000kW rating is available on 4 engine platforms: Cummins R-CC1250D5/S (QSK38-G5, 211 g/kW·h), Perkins R-P1250D5/S (4012-46TWG2A, 205 g/kW·h), MTU R-M1250D5/S (18V2000G26F, 199 g/kW·h), Mitsubishi R-JM1250D5/S (S12R-PTA, 221 g/kW·h). Efficiency for the R-CC1250D5/S and its alternatives is measured per ISO 3046-1. Units ship as open skid, weatherproof silent canopy or 20ft/40ft container; the silent build for the R-CC1250D5/S is the container enclosure at this rating, which holds ≤85 dB(A) at 7m. All 4 platforms (from the R-CC1250D5/S) are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
