Frequently Asked Questions — 100kW Diesel Generator

How much does a 100kW diesel generator cost?+
A 100kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds the Cummins R-DC113D5/S (6BTA5.9-G2 engine), rated 100 kW / 125 kVA prime and 110 kW / 138 kVA standby at 50Hz (1500 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford UCI274ES or Leroy-Somer TAL-A44-E for the R-DC113D5/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-DC113D5/S price within 24 hours.
What is the fuel consumption of a 100kW diesel generator?+
At 75% load a 100kW diesel generator consumes 18.8 L/h; at 100% load it rises to 25.1 L/h. The 6BTA5.9-G2 engine in the R-DC113D5/S works out at 211 g/kW·h per ISO 3046-1. Actual consumption on the R-DC113D5/S varies about ±5% with ambient conditions, load profile and fuel quality. At a diesel price of $1.0/L, running at 75% load costs roughly $19 per hour.
What can a 100kW diesel generator power?+
A 100kW set covers mid-size commercial and light-industrial loads: a supermarket with refrigeration and lighting, a clinic, a small factory, a mid-size construction site or a pump station. Standby is 110 kW / 138 kVA, which leaves starting margin for motor loads on top of the base load. Tell us your connected load and the largest motor you need to start and we will confirm whether 100kW or the next rating up fits better.
Which engine brands and configurations are available for a 100kW generator?+
H&C supplies the 100kW rating on one engine platform: Cummins (R-DC113D5/S with the 6BTA5.9-G2 engine, 211 g/kW·h). Units ship as open skid, weatherproof silent canopy or 20ft/40ft container; the silent canopy for the R-DC113D5/S holds ≤75 dB(A) at 7m. All R-DC113D5/S units are built to 50Hz (1500 rpm) as standard, with custom controls and ATS available on request.
