800kW Diesel Generator Set

Q: How much does an 800kW diesel generator cost?

An 800kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds 4 engine platforms (Cummins R-CC1000D5/S, Perkins R-P1000D5/S, MTU R-M1000D5/S, Mitsubishi R-JM1000D5/S), rated 800 kW / 1000 kVA prime and 880 kW / 1100 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford S6L1D-E4 or Leroy-Somer TAL-A49-E for the R-CC1000D5/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-CC1000D5/S / R-P1000D5/S / R-M1000D5/S / R-JM1000D5/S price within 24 hours.

Q: What is the fuel consumption of an 800kW diesel generator?

Fuel consumption for an 800kW diesel generator is 141.4-150.0 L/h at 75% load and 188.6-200.0 L/h at 100% load across the 4 platforms: Cummins R-CC1000D5/S 144.3 / 192.4 L/h; Perkins R-P1000D5/S 150.0 / 200.0 L/h; MTU R-M1000D5/S 141.4 / 188.6 L/h; Mitsubishi R-JM1000D5/S 147.1 / 196.2 L/h. Measured efficiency is 198-210 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 $141-150 per hour.

Q: What can an 800kW diesel generator power?

An 800kW set is built for large industrial and data-center duty: data centers, large hospitals, mining sites and mid-to-large manufacturing plants. At this rating Cummins, Perkins, MTU and Mitsubishi are available, so the same 880 kW / 1100 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 800kW or the next rating up fits better.

Q: Which engine brands and configurations are available for an 800kW generator?

The 800kW rating is available on 4 engine platforms: Cummins R-CC1000D5/S (KTA38-G5, 202 g/kW·h), Perkins R-P1000D5/S (4008TAG2, 210 g/kW·h), MTU R-M1000D5/S (16V2000G65, 198 g/kW·h), Mitsubishi R-JM1000D5/S (S12H-PTA, 206 g/kW·h). Efficiency for the R-CC1000D5/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-CC1000D5/S holds ≤75 dB(A) at 7m. All 4 platforms (from the R-CC1000D5/S) are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
