400kW Diesel Generator Set

A 400kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds 2 engine platforms (Cummins R-CC500D5/S, Perkins R-P500D5/S), rated 400 kW / 500 kVA prime and 440 kW / 550 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S5L1D-C4 or Leroy-Somer TAL-A473-C for the R-CC500D5/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-CC500D5/S / R-P500D5/S price within 24 hours.

Fuel consumption for a 400kW diesel generator is 70.0-72.5 L/h at 75% load and 93.3-96.7 L/h at 100% load across the 2 platforms: Cummins R-CC500D5/S 72.5 / 96.7 L/h; Perkins R-P500D5/S 70.0 / 93.3 L/h. Measured efficiency is 196-203 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 $70-72 per hour.

A 400kW set powers heavy commercial and industrial facilities: hospitals, manufacturing plants, commercial buildings, cold storage and mid-size data centers. At this rating Cummins and Perkins are available, so the same 440 kW / 550 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 400kW or the next rating up fits better.

The 400kW rating is available on 2 engine platforms: Cummins R-CC500D5/S (KTA19-G3A, 203 g/kW·h), Perkins R-P500D5/S (2506C-E15TAG2, 196 g/kW·h). Efficiency for the R-CC500D5/S and its alternatives is measured per ISO 3046-1. Units ship as open skid, weatherproof silent canopy or 20ft/40ft container; the silent canopy for the R-CC500D5/S holds ≤75 dB(A) at 7m. All 2 platforms (from the R-CC500D5/S) are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
