2015 Cummins 500kW 500GFGB Natural Gas Generator Set

This 2015 Cummins 500GFGB natural gas generator set is a low-hour, commercial-grade standby power solution designed for facilities, municipal sites, and mission-critical emergency applications. The unit is rated 500 kW standby at 60 Hz, operating at 1,800 RPM, and produces 277/480V power. With fewer than 500 original operating hours, this generator represents an excellent opportunity to acquire a lightly used Cummins natural gas standby package.

The generator is powered by a Cummins GTA28 spark-ignited natural gas engine and is equipped with a Stamford alternator. Controls are provided through a Cummins PowerCommand digital control panel, delivering full system monitoring, metering, alarms, and protective shutdowns. Electrical output is delivered through an integrated circuit breaker.

This unit is housed in a weatherproof enclosure and includes a 24-volt electric starting system, jacket water heater, automatic battery charger, battery charging alternator, and batteries installed. Additional features include a pancake-style internal exhaust silencer for noise reduction and a fully integrated standby support system.

Built on Cummins’ proven natural gas platform, this 500GFGB generator is well-suited for hospitals, data centers, commercial buildings, and industrial facilities requiring dependable 500 kW natural gas standby power with low operating hours.
