Construction activities require electrical power to run a variety of equipment and machinery used on the site where the construction takes place. Often such sites cannot utilize the national network of supply because they can be in areas with no connection to the national grid or places where grid supply does not reach or cannot supply electricity continuously. This is where the power industry comes into play by providing a generator to supply power where it is needed.

The type of equipment used at construction sites

Construction sites utilize various equipment needed to carry out various types of construction activities. For example, the construction of roads has specific equipment needs which are different from that required for the construction of buildings. Typically, construction equipment includes things such as excavators, bulldozers and rollers which are self-powered and does not need a generator. However, there are machines and tools that require the mobile power sources. Generators supply this electricity need.

Another important requirement on a construction site is lighting. Often, the contractor carries out construction work at night and sufficient light is a must. Furthermore, contractors will be carrying out a number of administrative duties through computers, laptops and mobile phones. Construction sites often require temporary buildings for staff that require electrical energy for powering many different appliances such as fridges, heaters and kitchen appliances. Thus, a particular generator is needed to supply power for all these applications.

Generator types commonly used on construction sites

Construction activities take place in various forms and can include the building of bridges, houses, shops, and roads, for example. They could also be employed to construct large commercial enterprises including malls and national highways.

High-powered generator

It is a generator that provides a large amount of power required in a large construction site. For example, earth moving equipment, material handling equipment, road construction equipment and concrete equipment are part of the construction activity that requires large amounts of energy. These generators require a very high voltage startup and these details should be factored in while determining the total power requirement.

Medium-powered generator

Medium-powered generators can generate electricity in the range of 5 kW to 200 kW and would be required for smaller construction activities such as building individual houses, small streets, low-rise apartments and repair works.

Standby generator

It is a generator that can come in very handy when the main generator supply stops working for some reason or another. These generators offer a temporary backup supply when the main generator is out of action for some reason, perhaps for maintenance. For Generator Rental information, visit

Portable generator

Areas where construction is taking place can spread over a large area and it becomes difficult to draw power from large central generators. By contrast, construction sites using multiple generators of different wattage are placed in strategic locations where power is needed. Portable generators can either come with wheels attached to them or be mounted on a base with wheels allowing them to be transported easily from one area to another.
