900 kVA Generators for Sale
A 900kVA generator delivers approximately 720kW of power output – sufficient capacity to run a medium-sized manufacturing facility, data centre, hospital, or large commercial building. At this output level, you’re looking at serious industrial power, typically deployed as either a standby generator for backup during grid outages or as a prime power source for sites without mains connection.We supply 900kVA diesel generators from the UK’s leading manufacturers including Perkins, Cummins, FG Wilson, and CAT. Units are available in open-frame configuration for plant rooms and enclosures, or as canopied silent generators for noise-sensitive environments.
900 kVA quick specifications: A 900 kVA diesel generator gives about 720 kW of prime power and around 792 kW on standby. At 400V three phase it supplies roughly 1299 amps per phase. Typical fuel use is about 99 to 180 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 £88,000 to £140,000 ex VAT, although engine, alternator, canopy, controls and installation affect the final quote.

900kVA Generators For Sale
For backup power or prime power source for your large industrial and business use, look no further than our huge range of 900kVA Generators we have for sale from the UK. We stock all major brands from Perkins Generators, to CAT, FG Wilson and Cummins Generators.
Are 900 kVA generators suitable for critical infrastructure?
Yes, 900 kVA generators are ideal for critical infrastructure, including airports, large hospitals, data centres, and government buildings. These facilities require a reliable backup power source to ensure that essential systems remain operational during outages. For example, in hospitals, a 900 kVA generator can power life-saving equipment, HVAC systems, and lighting, ensuring patient safety. In data centres, it can keep servers and networking equipment running, preventing data loss and service interruptions. Smaller critical facilities may find a 700kVA or 800kVA generator sufficient, while larger infrastructure projects often require 1000kVA or 1250kVA generators.
How do I manage the fuel consumption of a 900 kVA generator?
Managing the fuel consumption of a 900 kVA generator involves implementing load management strategies, regular maintenance, and using high-quality fuel. Load management ensures that the generator operates efficiently, avoiding unnecessary fuel consumption by matching output to demand. Regular maintenance, including cleaning filters, checking fuel lines, and inspecting the engine, helps maintain fuel efficiency. Additionally, using premium-grade diesel or other fuels recommended by the manufacturer can improve combustion and reduce overall consumption. If your power requirements allow, stepping down to a 600kVA or 500kVA generator will naturally reduce fuel costs.
How many kW is a 900 kVA generator?
At a typical 0.8 power factor, a 900 kVA generator provides about 720 kW of prime power. Standby power is commonly around 792 kW, but the exact rating should be checked on the chosen model’s datasheet.
How many amps does a 900 kVA generator supply?
At 400V three phase, a 900 kVA generator supplies about 1299 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 900 kVA generator use per hour?
A diesel generator of this size typically uses about 99 to 180 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 900 kVA generator cost?
Indicative new prices are commonly around £88,000 to £140,000 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 900 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.
