On construction sites, generators are one of the essential pieces of equipment. They can provide temporary power for construction sites and other industrial work and keep equipment running properly.

Choosing the right power and type of generator is vital to the success of the job, so how many kilowatts are the average generators used on construction sites? Let's take a closer look.

Electricity requirements on site

Firstly, it is important to understand how much power is required on the site. These requirements can vary depending on many factors, such as

Building construction requirements

The number and type of various power tools and machinery

Temporary equipment (e.g. lights) and electricity consumption

These factors will determine how many kilowatts of generator you will need to meet the requirements. Therefore, please ensure that you have accurately determined your requirements before purchasing.

Power of generators

The power of a generator is usually expressed in kilowatts (kW) or kilovolt-amperes (kVA). kW indicates the actual useful power produced by the generator, but kVA indicates the maximum power that the generator can produce, including reactive power and reverse power. Therefore, kW is more commonly used to describe the actual power output of a generator.

In general, generators for construction sites need to be more powerful than for other applications. This is because they must support the simultaneous operation of multiple power tools, machinery and equipment. Typically, standard site generators range from 5 kW to 1000 kW. This range is sufficient for most building construction, temporary energy requirements.

Types of generators for use on site

In addition to the power, you also need to consider the type of generator to be used. There are two main types:

Diesel generators

Petrol generators

Diesel generators are widely used in industry, mainly because of their reliability and fuel efficiency. However, petrol generators are also a good choice for smaller sites or where a mobile generator is required.

You will also need to determine whether you need to purchase a portable generator or a permanent generator installed in a fixed location. For smaller work projects, a portable generator will usually be used. For larger projects, a permanent generator will usually need to be installed to meet the power demand.

How to choose the right generator

Choosing the right generator is very important. If you choose the wrong capacity or type it could lead to breakdowns or equipment failure. Let's look at some key points for choosing the right generator:

Determine the power requirements you need: take into account all equipment and tools that may require power to ensure you have chosen the right capacity.

Know whether you need a mobile or fixed installation generator

Choose a diesel or petrol generator: this will depend on your specific needs

Purchase a high-quality unit to ensure its long-term reliability.

Whichever type of generator you choose, it will need to be maintained to ensure it runs properly. Regular checks of fuel, filters, batteries, wiring connectors and other components will help you avoid unnecessary downtime and repairs.
