500kVA Generators
A 500kVA generator delivers approximately 400kW of power output – a versatile capacity for medium-sized industrial operations, healthcare facilities, retail centres, and commercial buildings needing reliable standby power or prime power generation.
500 kVA quick specifications: A 500 kVA diesel generator gives about 400 kW of prime power and around 440 kW on standby. At 400V three phase it supplies roughly 722 amps per phase. Typical fuel use is about 55 to 100 litres an hour depending on load. Sets this size suit data centres, hospitals, large industrial plants, major events and other critical power applications. New prices are typically around £48,000 to £80,000 ex VAT, although engine, alternator, canopy, controls and installation affect the final quote.

500 kVA Generators for Sale
A 500kVA generator delivers substantial power output for large-scale commercial operations, industrial manufacturing facilities, hospitals, data centres, hotels, shopping centres, distribution warehouses, and major construction projects. These heavy-duty diesel sets provide reliable performance for both mission-critical standby backup and continuous prime power generation, making them a popular choice for businesses that cannot afford operational downtime.
Our 500kVA diesel generators are available in both soundproofed canopy enclosures for urban installations and noise-controlled environments, and open-frame configurations for industrial sites where acoustic attenuation isn’t a priority. Each unit can be specified with automatic transfer switching, synchronisation for parallel operation, remote monitoring capabilities, and comprehensive load management systems to ensure seamless integration with your existing electrical infrastructure.
Built to deliver consistent performance under the most demanding conditions, 500kVA generators are commonly deployed in healthcare facilities requiring uninterrupted power supply, manufacturing plants where production continuity is critical, large commercial properties needing comprehensive business continuity protection, and temporary power installations on major construction sites. They offer excellent fuel efficiency, emissions compliance, and straightforward maintenance requirements for both standby and continuous operation.
At Generator Warehouse, we provide complete project support from initial consultation through to commissioning and beyond. This includes expert technical specification, competitive pricing on all major brands, nationwide delivery and professional installation, comprehensive commissioning services, and ongoing maintenance support. Our experienced technical team will work with you to assess your load profile, runtime requirements, fuel infrastructure, and site constraints to recommend the most suitable 500kVA diesel generator for your specific application.
What kind of load can a 500 kVA generator handle?
A 500 kVA generator can handle significant industrial and commercial loads, making it suitable for applications such as powering multiple heavy machines, large HVAC systems, and complex electrical systems. It can support critical infrastructure like hospitals, data centers, and manufacturing plants, where uninterrupted power is essential. The generator’s capacity ensures that it can manage peak loads and power surges, providing stable and reliable energy.
Can a 500 kVA generator be used in parallel with others?
Yes, a 500 kVA generator can be synchronized with other generators to increase total power output or provide redundancy. This is especially useful in applications where power demands exceed the capacity of a single generator or where continuous operation is critical. Parallel operation allows for load sharing, reduces the risk of overloading a single generator, and ensures that power is still available even if one generator requires maintenance or fails
How fuel-efficient is a 500 kVA generator?
A 500 kVA generator typically consumes around 25-30 litres of diesel per hour at full load. Fuel efficiency can be enhanced through features like load management and variable speed operation, which adjust the generator’s output based on demand. Regular maintenance, such as keeping filters clean and ensuring proper fuel quality, also contributes to optimal fuel consumption. For businesses with high power demands, investing in fuel-efficient models can lead to significant cost savings over time.
What can a 500 kVA generator power?
This size is commonly used for data centres, hospitals, large industrial plants, major events and other critical power applications. The right choice still depends on the total running load and the starting current of the largest motors or equipment.
Are your 500kVA generators soundproof?
Yes, we offer canopied (soundproof) and open-frame variants. The soundproof models are ideal for noise-sensitive environments and are housed in weather-resistant enclosures with built-in silencers.
What are the fuel consumption rates for a 500kVA diesel generator?
Fuel consumption varies slightly by brand and load but typically ranges from 80 to 110 litres per hour at 75% load. We can provide exact figures based on the model you’re interested in.
Do you offer installation and commissioning services?
Yes. Generator Warehouse provides nationwide delivery, installation, and on-site commissioning by qualified engineers. We can also assist with load testing and electrical integration.
Are the generators compliant with UK regulations?
All our 500kVA generators comply with UK and EU emissions standards, CE marking, and are built to ISO quality standards. We also ensure compliance with local noise and safety regulations.
How long is the warranty on a 500kVA generator?
Most of our generators come with a 12 to 24-month warranty (or a set number of hours). Extended warranty and service packages are available upon request.
How many kW is a 500 kVA generator?
At a typical 0.8 power factor, a 500 kVA generator provides about 400 kW of prime power. Standby power is commonly around 440 kW, but the exact rating should be checked on the chosen model’s datasheet.
How many amps does a 500 kVA generator supply?
At 400V three phase, a 500 kVA generator supplies about 722 amps per phase. This is a guide only: a qualified electrician should confirm cable, switchgear and protection sizes for the installation.
How much fuel does a 500 kVA generator use per hour?
A diesel generator of this size typically uses about 55 to 100 litres an hour, depending on load. Treat this as a planning range rather than a model-specific figure and check the selected generator’s fuel-consumption curve for an exact estimate.
How much does a 500 kVA generator cost?
Indicative new prices are commonly around £48,000 to £80,000 ex VAT. Engine and alternator brand, acoustic canopy, control panel, fuel tank, delivery, commissioning and installation can all change the final quote.
