What is an 80kW Diesel Generator?
An 80kW diesel generator is a medium-capacity power solution designed to provide reliable electricity for industrial, commercial, and backup applications. It converts diesel fuel into electrical energy using a diesel engine coupled with an alternator. This type of generator is commonly used in factories, construction sites, office buildings, and hospitals to ensure continuous power during outages or in off-grid locations. Known for its durability, fuel efficiency, and stable performance, an 80kW diesel generator is ideal for powering essential equipment, lighting systems, and machinery.
How to Choose the Right 80kW Diesel Generator?
Choosing the right 80kW diesel generator is essential to ensure reliable power supply and long-term performance for your project. Whether you need backup power for a commercial building, continuous power for a factory, or temporary electricity for a construction site, selecting the correct generator requires careful consideration.
First, you should evaluate your actual power requirements, including peak load and running load, to confirm that an 80kW generator is suitable. Next, consider the type of application—standby, prime, or continuous use—as this will affect the generator configuration and durability. Engine brand is also an important factor, with well-known options like Cummins, Perkins, and Weichai offering different levels of performance and cost.
In addition, pay attention to fuel efficiency, noise level (silent or open type), and installation environment. Features such as an automatic transfer switch (ATS) and control panel can further improve convenience and safety.
By understanding these key factors, you can choose an 80kW diesel generator that meets your specific needs while maximizing efficiency and minimizing operating costs.

80KW Diesel Generators Price
The price of an 80kW diesel generator can vary depending on the engine brand, alternator quality, configuration, and whether the unit is open type or silent type. In general, an 80kW generator typically ranges from $4,000 to over $30,000 in the global market. For example, some industrial models such as Cummins 80kW diesel generators can cost around $35,000–$42,000, while other commercial standby units may be priced above $30,000 depending on specifications.
In the export market, especially from China, an 80kW diesel generator powered by brands such as Cummins, Perkins, Weichai, Yuchai, Shangchai, or Volvo may cost roughly $4,000 to $8,000 for standard open-type models, while silent or containerized units are usually more expensive.
80KW Diesel Generators FAQs
1. What is an 80kW diesel generator used for?
An 80kW diesel generator is commonly used to supply backup or primary power for small factories, construction sites, commercial buildings, farms, and hospitals. It can power equipment, lighting systems, and essential electrical loads during power outages.
2. How much power can an 80kW generator produce?
An 80kW generator can produce about 80 kilowatts (100 kVA) of electrical power. This is usually enough to run multiple machines, air conditioning units, lighting systems, and other industrial or commercial equipment.
3. How much fuel does an 80kW diesel generator consume?
Fuel consumption depends on the load and engine brand. On average, an 80kW diesel generator consumes about 16–20 liters of diesel per hour at full load.
4. What brands of engines are used in 80kW diesel generators?
Popular engine brands for 80kW diesel generators include Cummins, Perkins, Weichai, Yuchai, Shangchai, and Volvo Penta. Each brand offers different levels of performance, fuel efficiency, and durability.
5. What is the difference between prime power and standby power?
Prime power refers to the generator’s ability to run continuously as the main power source.
Standby power is used as emergency backup power when the utility grid fails.
6. How long can an 80kW diesel generator run continuously?
With proper maintenance and adequate fuel supply, an 80kW diesel generator can run continuously for 8–24 hours or longer, depending on the fuel tank capacity and operating conditions.
