500kW Generator Rental (625kVA)

Prime Power Rental’s 500kW generator rental (625kVA) provides reliable power to meet the most demanding requirements. They are designed and built to withstand tough environments at construction sites and provide dependable temporary power at entertainment venues, construction sites, and disaster recovery operations. And to safeguard the environment, the 500kW generator features an integrated 24-hour fuel tank with a fluid containment system. 

 The 500kW / 625kVA diesel generator offers a prime rating of 455kW (three-phase) and a standby rating of 500kW (three-phase).  Output voltages of Three-Phase (120/208V, 277/480V) are available.  An electronic governor maintains frequency to ± 0.25% from no load to full load. It features an auto-start and stop that allows the generator to start from a remote location. The unit features a powder-coated, weatherproof steel housing that allows a substantially low operating noise level of 70 dB(A). A comprehensive digital control panel provides instrumentation including an AC ammeter, AC voltmeter, frequency meter, AC circuit breaker, engine gauges, and much more.  Unit is available with utility-grade switchgear and can be capable of being paralleled with other like generators or the power grid to offer base load & peak shaving capabilities.
