500kW Industrial & Commercial Generators

Our selection of new and used 500kW industrial and commercial generators for maximum peace of mind.

Why Choose a New 500kW Generator?

  • Large Commercial Establishments: Ensuring continuous operation for shopping malls, large office buildings, convention centers, and major retail outlets. 
  • Industrial Applications: Powering manufacturing lines, large-scale workshops, heavy machinery, and critical processes in diverse industrial sectors. 
  • Data Centers & Server Farms: Providing essential backup power to protect sensitive data and maintain uptime for critical IT infrastructure. 
  • Agricultural & Livestock Operations: Supporting extensive farming facilities, large irrigation systems, and specialized processing plants. 
  • Municipal & Public Utilities: Offering reliable emergency power for water treatment plants, pumping stations, and critical civic infrastructure. 

Why Choose a Used 500kW Generator?

  • Transportation and Installation: These are very large and heavy machines. Factor in specialized rigging, transportation, and installation costs, which can be significant, regardless of whether the unit is new or used.
  • Fuel Consumption: At 500kW, fuel consumption is substantial (e.g., diesel: around 30-35 gallons per hour at full load). Ensure your fuel storage and delivery system are adequate.
  • Maintenance & Service: While reliable, a 500kW generator requires professional maintenance. Verify parts availability and locate qualified service technicians in your area.
  • Emissions Regulations: Be acutely aware of local, state, and federal emissions regulations (e.g., EPA Tier standards in the U.S.). Older generators might not meet current strict emissions standards for continuous prime power applications but may be permissible for standby use. Always check with your local authorities.
  • Thorough Inspection and Load Testing: For a generator of this size, a pre-purchase inspection by an independent, qualified technician is highly recommended. Always insist on a recent, comprehensive load test report showing the generator can produce its rated output.
  • Seller Reputation: More than ever with large assets, the reputation of the used generator dealer is paramount. Choose a dealer known for rigorous inspection, testing, and excellent customer service.

Choosing the right fuel type for your 500kW generator depends on your application, location, and fuel availability. At Generator Source, we offer a wide selection of 500kW generators powered by diesel, natural gas, or propane—each with distinct benefits to match your power needs and infrastructure.

Diesel: The most common fuel type for 500kW systems, known for high energy density, reliable performance, and longer run times. Ideal for standby and prime applications in industrial and commercial settings.

Natural Gas: A cleaner-burning option that connects directly to a utility gas line. Offers reduced emissions and can be more cost-effective in regions with stable gas infrastructure.
