Frequently Asked Questions — 80kW Diesel Generator

How much does an 80kW diesel generator cost?+
An 80kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds 2 engine platforms (Cummins R-DC100D5/S, Perkins R-P100D5/S), rated 80 kW / 100 kVA prime and 88 kW / 110 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford UCI274C or Leroy-Somer TAL-A44-D for the R-DC100D5/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-DC100D5/S / R-P100D5/S price within 24 hours.
What is the fuel consumption of an 80kW diesel generator?+
Fuel consumption for an 80kW diesel generator is 15.3 L/h at 75% load and 20.4 L/h at 100% load across the 2 platforms: Cummins R-DC100D5/S 15.3 / 20.4 L/h; Perkins R-P100D5/S 15.3 / 20.4 L/h. Measured efficiency is 214 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 $15 per hour.
What can an 80kW diesel generator power?+
An 80kW set covers mid-size commercial and light-industrial loads: restaurants and supermarkets, small factories, clinics, mid-size construction sites and pump stations. At this rating Cummins and Perkins are available, so the same 88 kW / 110 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 80kW or the next rating up fits better.
Which engine brands and configurations are available for an 80kW generator?+
The 80kW rating is available on 2 engine platforms: Cummins R-DC100D5/S (6BT5.9-G2, 214 g/kW·h), Perkins R-P100D5/S (1104C-44TAG2, 214 g/kW·h). Efficiency for the R-DC100D5/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-DC100D5/S holds ≤75 dB(A) at 7m. All 2 platforms (from the R-DC100D5/S) are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
