250 kVA Generators
Generator Warehouse presents a wide selection of 250kVA generators, built to handle the most demanding power requirements of large-scale industrial facilities, major infrastructure projects, and extensive backup power systems. With advanced features, robust construction, and exceptional reliability, our generators are the ultimate solution for your high-capacity power needs.
A 250kVA generator delivers substantial power for large commercial operations, industrial manufacturing, hospitals, data centres, hotels, shopping centres, and major construction sites. These heavy-duty diesel sets provide dependable performance for both critical standby backup and continuous prime power applications. At Generator Warehouse, we stock premium 250kVA models from industry-leading manufacturers including Cummins, FG Wilson, and Perkins.
Our 250kVA diesel generators are available in both soundproofed canopy enclosures for urban locations and noise-sensitive environments, and open-frame configurations for industrial sites where acoustic performance is less critical. Each unit can be specified with automatic transfer switching, synchronisation capabilities for parallel operation, remote monitoring, and comprehensive load management systems.
Built to withstand continuous operation in demanding conditions, 250kVA generators excel in applications requiring robust, fuel-efficient power generation. They’re commonly deployed to protect mission-critical infrastructure, maintain production in manufacturing facilities, power large temporary installations, and provide backup for commercial properties where business continuity is paramount.
At Generator Warehouse, we provide complete project support including expert technical specification, competitive pricing, nationwide delivery and installation, commissioning services, and ongoing maintenance support. Our experienced team will assess your load requirements, runtime expectations, and site constraints to recommend the most suitable 250kVA diesel generator for your specific application.
Whether you need emergency standby power or prime power generation for off-grid operations, our 250kVA range delivers the reliability, efficiency, and performance your business demands.
How much space does a 250 kVA generator require?
A 250 kVA generator requires around 3-4 square metres of space, including adequate clearance for maintenance and ventilation. The installation site should be well-ventilated to prevent overheating and should have enough room for access to fuel tanks and control panels. It’s also important to consider soundproofing, especially if the generator is located near offices or residential areas. Proper space planning ensures safe and efficient operation. Smaller units such as 100kVA or 150kVA generators require less space, while larger 400kVA or 500kVA generators will need a more substantial footprint.
Is a 250 kVA generator energy-efficient?
A 250 kVA generator is energy-efficient, particularly when equipped with advanced features like load management and variable speed operation. These features allow the generator to adjust its output based on demand, optimising fuel consumption and reducing emissions. Regular maintenance, such as keeping air filters clean and using high-quality fuel, further enhances energy efficiency, lowering operational costs over time. If your power requirements are lower, a 150kVA or 200kVA generator will offer improved fuel economy for smaller applications.
Can a 250 kVA generator be used in remote locations?
Yes, a 250 kVA generator is ideal for use in remote locations, such as mining sites, construction projects, and rural areas without access to the grid. It provides reliable power for essential operations, including tools, machinery, and temporary living facilities. To ensure continuous operation, it’s important to have a steady supply of fuel and to perform regular maintenance. Depending on the environment, additional considerations such as weather protection and transportation logistics may be necessary. For smaller remote operations, a 60kVA or 80kVA generator may suffice, while larger sites often require 300kVA or 350kVA generators.
How many kW is a 250 kVA generator?
At standard 0.8 power factor, a 250 kVA generator provides about 200 kW of prime power. Standby power is typically around 220 kW, but always compare the selected model’s published rating.
How many amps does a 250 kVA generator supply?
At 400V three-phase, a 250 kVA generator supplies roughly 361 amps per phase. Your electrician should confirm cable sizes, protection and switchgear for the installation.
How much fuel does a 250 kVA generator use per hour?
As a planning estimate, expect roughly 28 to 50 litres per hour depending on load, engine and operating conditions. Check the selected model’s fuel-consumption curve before sizing storage or calculating running costs.
How much does a 250 kVA generator cost?
New 250 kVA diesel generators are typically around £24,000 to £34,000 ex VAT. The engine, alternator, canopy, controls, delivery, commissioning and installation can change the final quote.
What can a 250 kVA generator power?
A 250 kVA set is commonly used for large construction sites, medium data centres, larger warehouses, processing plants and multi-building estates. Confirm the starting current and combined load of the equipment before selecting a set.
