GAS GENERATOR SETS

Ranging from 86 to 4045 ekW (108 to 5056 kVA) in a single unit, our gas generator sets are easy to select, permit and install. Our industrial and commercial gas generator sets are proven for reliable operation with a wide range of gaseous fuels including natural gas, biogas from landfills and digesters, coal gas, propane and alternative fuels. We build durable, low life-cycle cost power systems that we integrate with controls, exhaust systems, fuel train, combined cooling heat & power skids and switchgear.

Standby Power Rating / Demand Response: Output available with varying load for the duration of the interruption of normal source power. Average power output is 70% of the standby rated ekW. Typical operation is 200 hours per year, with maximum expected usage of 500 hours per year.

Emergency Standby Power (ESP): Output available with varying loads for the duration of the interruption of the normal source power. Average power output is 70% of the ESP rated ekW. Typical operation is 50 hours per year with a maximum expected usage of 200 hours per year.

Prime Power Rating: Output available with varying load for an unlimited time. Average power output is 70% of the prime rated ekW. Typical peak demand is 100% of prime rated ekW.

Continuous Power Rating: Output available with non-varying load for an unlimited time. Average power output is 70-100% of the continuous rated ekW. Typical peak demand is 100% of continuous rated ekW for 100% of operating hours.
