1500kW Diesel Generator Set

Q: How much does a 1500kW diesel generator cost?

A 1500kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds 3 engine platforms (Cummins R-CC1875D5/S, Perkins R-P1875D5/S, Mitsubishi R-JM1875D5/S), rated 1500 kW / 1875 kVA prime and 1600 kW / 2000 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S7L1D-F4 or Leroy-Somer LSA 52.3 S5 for the R-CC1875D5/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-CC1875D5/S / R-P1875D5/S / R-JM1875D5/S price within 24 hours.

Q: What is the fuel consumption of a 1500kW diesel generator?

Fuel consumption for a 1500kW diesel generator is 269.2-282.6 L/h at 75% load and 358.9-376.8 L/h at 100% load across the 3 platforms: Cummins R-CC1875D5/S 269.2 / 358.9 L/h; Perkins R-P1875D5/S 282.6 / 376.8 L/h; Mitsubishi R-JM1875D5/S 277.2 / 369.6 L/h. Measured efficiency is 201-211 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 $269-283 per hour.

Q: What can a 1500kW diesel generator power?

A 1500kW set delivers utility-scale power: power plants, industrial parks, large data centers and national-grid support. At this rating Cummins, Perkins and Mitsubishi are available, so the same 1600 kW / 2000 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 1500kW or the next rating up fits better.

Q: Which engine brands and configurations are available for a 1500kW generator?

The 1500kW rating is available on 3 engine platforms: Cummins R-CC1875D5/S (KTA50-G16A, 201 g/kW·h), Perkins R-P1875D5/S (4016TAG1A, 211 g/kW·h), Mitsubishi R-JM1875D5/S (S16R-PTA2, 207 g/kW·h). Efficiency for the R-CC1875D5/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-CC1875D5/S is the container enclosure at this rating, which holds ≤85 dB(A) at 7m. All 3 platforms (from the R-CC1875D5/S) are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
