List of 1000kw diesel generator sets
1000kw diesel generator related issues
1. What is the average fuel consumption of a 1000kW diesel generator at different load levels?
Fuel efficiency is a critical factor for operational budgeting. Typically, a 1000kW generator consumes approximately 260–280 liters (68–74 gallons) per hour at 100% load. At 75% load, which is the common optimal operating range, consumption drops to roughly 190–210 liters (50–55 gallons) per hour. To maximize fuel economy, we recommend selecting a unit with electronic fuel injection and ensuring regular maintenance of the fuel filters and injectors.
Based on the actual load level of your diesel generator, you can click on the fuel consumption calculation page of the diesel generator set to calculate it
2. Can a 1000kW generator be used for Prime Power, or is it only for Standby use?
Our 1000kW units are available in both Standby and Prime ratings.
Standby Power (ESP): Designed for emergency use during utility power outages. It should not be overloaded and is typically rated for a maximum of 200–500 hours of operation per year.
Prime Power (PRP): Suited for continuous operation in areas without a reliable grid. It can handle variable loads for unlimited hours, usually with a 10% overload capacity available for 1 hour in every 12.
Please specify your application so our engineers can provide the correct engine configuration.- The unit consumption of diesel varies depending on the type of diesel engine used. If you have determined the unit consumption of a certain brand of diesel engine, please go to: Diesel Generator Fuel Calculator
3. What are the key ventilation and space requirements for installing a unit of this size?
A 1000kW generator generates significant heat and requires massive airflow for cooling and combustion. The installation site must have:
Air Intake & Exhaust: Sufficient louver space to prevent "short-circuiting" of hot air. The radiator discharge should be ducted directly to the outside.
Footprint: A reinforced concrete pad (foundation) capable of supporting the static weight (approx. 8,000–12,000kg) and absorbing dynamic vibrations.
Clearance: A minimum of 1.5 to 2 meters of clearance around the unit for maintenance access and safety compliance.
4. Does this 1000kW generator support synchronization with other units or the utility grid?
Yes, our 1000kW generators come equipped with advanced digital controllers (such as Deep Sea or ComAp) that support Parallel/Synchronized operation. This allows you to:
Link multiple units together to meet a total load exceeding 1000kW.
Implement "N+1" redundancy for critical data centers or hospitals.
Perform "Seamless Transfer" (Bumpless Transfer) back to the grid once utility power is restored, ensuring zero downtime for your facility.
