Construction connection

At the start of a construction project, a temporary construction connection is indispensable. This power supply saves time and costs, and makes it easy to comply with more stringent construction regulations around sustainability and efficiency.

Frax sees that a construction connection is often the first step to a smooth construction process, especially if you want to use innovative solutions such as Battery Energy Storage Systems (BESS) later on.

What is a construction connection?

A construction connection is a temporary electrical connection that you use during the construction phase to power all necessary equipment. This can range from basic tools and construction lights to larger machinery, depending on the size of your project.

With a construction connection, you have sufficient energy capacity at the construction site so you can get to work safely and efficiently. In addition, proper planning for the right connection helps avoid unnecessary costs or delays.

Applying for a building connection: step-by-step plan

Applying for a construction connection is best done step by step. This ensures an efficient process and avoids unnecessary delays or costs. Below you will find a clear guide:

  1. Determine capacity needs: consider how much power you will need during construction. This depends, among other things, on the kind of tools and machines you want to use. This will help you avoid requesting too little or too much power.
  2. Contact grid operator or installer: contact the grid operator in your area or consult a licensed installer. They can advise you on the options available, the capacity required and the exact cost.
  3. Collect documents and data: have your building permit, construction site and any technical specifications ready. This information is crucial to the smooth processing of your application.
  4. Submit application: then submit all data to the grid operator. You will receive an offer based on your project data. After approval and signature, the construction connection will be scheduled.
  5. Inspection and installation: if necessary, the grid operator conducts a site visit, plans excavation work and installs the connection. Once everything is in order, you can use the new power supply immediately.

This roadmap will give you a clear overview of what is involved in applying for a building connection. By proceeding carefully and starting on time, you will ensure a safe and reliable energy supply during your construction project.

How long does an application for a construction connection take?

On average, it takes several weeks to sometimes a few months for a construction connection to be fully realized. The exact turnaround time depends on the availability of the grid operator and the complexity of your project. During busy periods, or when many requests come in at once, it may take longer.

In addition, factors such as the capacity required, the accessibility of your construction site and any permits play a role in the waiting time. For example, construction power requests in an urban area may be completed faster than in a remote location where additional infrastructure must be built. The type of connection (single-phase, three-phase or higher power) also impacts delivery time.

Cost of a construction connection

The cost of a construction connection depends on several factors, including the power required, the length of the construction phase and the location of your project.

A basic form of building connection tends to be cheaper than a high-capacity connection, because you pay additional network costs with a higher capacity. The period for which the connection is needed also determines the price: the longer the lease, the higher the cost.

Convert or remove building connection

Once the construction phase is complete, you can choose to convert your construction connection to a final connection. This is often beneficial if you want to continue using the existing electrical infrastructure and not install new cables or meters. The grid operator then checks that the current facility meets the requirements for a permanent connection.

Is the building connection no longer needed? Then you can also have it removed. This can be useful when your construction project is finished and you no longer need a temporary connection. In such a case, you simply request the grid operator to remove the facility, after which the meter box and cables will be removed. Keep in mind, however, that there may be charges for both conversion and removal.

Construction connection: a strong foundation for your construction project

A construction connection is an indispensable link to get work done safely and efficiently on your job site. By following the right steps and getting timely advice, you will keep the construction schedule running smoothly and avoid high costs. Whether you are starting a new project as an individual or a professional, a reliable construction connection is the ideal springboard to a sustainable end result. With Frax's expertise and good cooperation with the grid operator, you will lay the foundation for a modern, energy-efficient future.

Frequently Asked Questions

Can an individual apply for a construction power connection?

Yes, even as an individual you can apply for a building connection. This is often done through your installer or contractor, but you may also arrange it yourself directly with the grid operator. It is important that you have the correct data and permits at hand.

How long can a temporary construction connection stay?

This depends on the terms of the grid operator. Generally, the connection may stay as long as your construction project lasts. Once your construction is complete, you can have the construction connection converted to a permanent connection or removed.

Can a construction connection be reused for another project?

In some cases this is possible, but it depends on the location and the desired capacity. The system operator assesses whether the existing connection is suitable for a new project and whether relocation or modification is technically feasible.
