150kVA Generators for Sale UK
When you need serious power, turn to Generator Warehouse’s collection of 150kVA generators. Engineered for the most demanding industrial environments, major infrastructure projects, and large-scale backup power systems, our generators combine cutting-edge technology with heavy-duty construction to deliver unrivalled performance and reliability.
A 150kVA generator provides substantial power capacity for medium to large commercial operations, manufacturing facilities, hospitals, hotels, leisure centres, and construction projects. These robust diesel sets offer the perfect balance between portability and power output, making them ideal for both standby backup and prime power applications. At Generator Warehouse, we stock quality 150kVA models from industry-leading manufacturers including Cummins, CAT, FG Wilson, and Perkins.
Our 150kVA diesel generators are available in both soundproofed canopy enclosures for urban and noise-sensitive locations, and open-frame configurations for industrial sites where acoustic performance is less critical. Each unit can be specified with automatic transfer switching, remote monitoring, and load management systems to ensure seamless integration with your existing electrical infrastructure.
Built to withstand continuous operation and harsh environments, 150kVA generators deliver fuel-efficient performance with low emissions and straightforward maintenance requirements. Whether you’re specifying backup power for a data centre, prime power for a remote facility, or temporary power for a major construction project, our team will help you configure the right solution.
At Generator Warehouse, we provide comprehensive support including competitive pricing, expert specification advice, nationwide delivery, professional installation, and ongoing servicing. We’ll work with you to understand your load requirements, runtime needs, and site constraints to recommend the most suitable 150kVA generator for your application.
Is a 150 kVA generator enough for a large office building?
Yes, a 150 kVA generator is sufficient to power a large office building, including critical systems such as HVAC, elevators, lighting, and IT infrastructure. It can support multiple floors of operations, ensuring business continuity during power outages. This makes it ideal for corporate offices, financial institutions, and other commercial facilities where reliable power is essential to daily operations and data security. For smaller office buildings, a 80kVA or 100kVA generator may be adequate, while larger corporate headquarters often require 200kVA or 250kVA generators.
What is the typical fuel efficiency of a 150 kVA generator?
The fuel efficiency of a 150 kVA generator varies depending on the load and operating conditions, but it typically consumes about 15-17 litres of diesel per hour at full load. Generators with advanced fuel management systems can optimise fuel consumption, reducing operational costs. Regular maintenance, such as cleaning filters and ensuring proper load management, also plays a significant role in maintaining fuel efficiency. If fuel economy is a priority and your power demands allow, a 60kVA or 70kVA generator will offer lower consumption rates.
How many kW is a 150 kVA generator?
At a typical 0.8 power factor, a 150 kVA generator provides about 120 kW of prime power. Standby power is commonly around 132 kW, but the exact rating should be checked on the chosen model’s datasheet.
How many amps does a 150 kVA generator supply?
At 400V three phase, a 150 kVA generator supplies about 217 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 150 kVA generator use per hour?
A diesel generator of this size typically uses about 16 to 30 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 150 kVA generator cost?
Indicative new prices are commonly around £15,000 to £22,000 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 150 kVA generator power?
This size is commonly used for commercial premises, medium construction sites, agricultural operations, workshops and small industrial loads. The right choice still depends on the total running load and the starting current of the largest motors or equipment.
