700 kVA Generators
700kVA generator delivers approximately 560kW of power – the capacity needed for large commercial premises, data centres, manufacturing facilities, and major construction projects requiring reliable standby power or continuous prime power.We supply 700kVA diesel generators from leading manufacturers including Cummins, Perkins, FG Wilson, and CAT. Units are available in open-frame or canopied silent generator configurations, with full delivery and installation services across the UK.At this output level, typical applications include server room backup, hospital critical systems, shopping centres, and large-scale business backup installations. If you need slightly more or less capacity, see our 600kVA or 800kVA generators.
700 kVA quick specifications: A 700 kVA diesel generator gives about 560 kW of prime power and around 616 kW on standby. At 400V three phase it supplies roughly 1010 amps per phase. Typical fuel use is about 77 to 140 litres an hour depending on load. Sets this size suit large data centres, utilities, heavy industry, critical infrastructure and major site power systems. New prices are typically around £68,000 to £110,000 ex VAT, although engine, alternator, canopy, controls and installation affect the final quote.

700kVA Generators for Sale from UK
Browse our range of 700 kVA generators, suitable for both industrial and commercial use, whether that be large premises, data centres, construction sites or other projects. We have all major brands available and can deliver and install the diesel generator for you.
Can a 700 kVA generator support continuous operation?
Yes, a 700 kVA generator is designed for continuous operation, making it ideal for large-scale industrial and commercial applications. It can run continuously as a primary power source in off-grid locations or as a backup power supply in areas with unstable electricity. Regular maintenance and monitoring are essential to ensure long-term reliability and efficiency. These generators are built to handle heavy loads over extended periods, providing a stable and dependable power supply. For slightly lower power requirements, a 600kVA generator may be suitable, while larger operations may benefit from an 800kVA or 900kVA generator.
What kind of cooling system does a 700 kVA generator use?
Most 700 kVA generators use a liquid cooling system, which circulates coolant through the engine to manage temperature and prevent overheating. This system is essential for maintaining optimal performance, especially during continuous operation or when the generator is running at full load. Liquid cooling is more effective than air cooling in larger generators, as it provides consistent temperature control and allows the generator to operate efficiently in various environmental conditions. This cooling technology is standard across our higher capacity range, including 500kVA and 1000kVA generators.
How many kW is a 700 kVA generator?
At a typical 0.8 power factor, a 700 kVA generator provides about 560 kW of prime power. Standby power is commonly around 616 kW, but the exact rating should be checked on the chosen model’s datasheet.
How many amps does a 700 kVA generator supply?
At 400V three phase, a 700 kVA generator supplies about 1010 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 700 kVA generator use per hour?
A diesel generator of this size typically uses about 77 to 140 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 700 kVA generator cost?
Indicative new prices are commonly around £68,000 to £110,000 ex VAT. Engine and alternator brand, acoustic canopy, control panel, fuel tank, delivery, commissioning and installation can all change the final quote.
What can a 700 kVA generator power?
This size is commonly used for large data centres, utilities, heavy industry, critical infrastructure and major site power systems. The right choice still depends on the total running load and the starting current of the largest motors or equipment.
