How to realize medium voltage connection?


Obtaining and implementing medium voltage connections to the grid from the grid operator is a fairly complex process. However, as long as you know how to do it. In this blog, we've pointed you through this route and suggested ways to help you. In many cases, the journey starts with the conclusion that your factory, distribution center, or whatever you're doing needs a more "heavy" connection than the standard offered by the network operator in your area.

Request the network administrator

The first step is to submit a request to the network operator ( This is quite a time consuming task because, for example, you have to clearly indicate where the station should be. Once the request is filled out and sent, you will receive a quote for the requested connection within a few days, known as a "cut." This is because the network operator's network line is cut and a branch is created to the location where trafoStation will be installed. If you agree to this offer, send it back for signature and pay down payment, then the delivery time starts. This could take more than 20 weeks!

The next step is to provide measuring equipment from an approved measuring company. This measuring device measures how much energy you burn; The measurement company will track it for you. You can find a list of authorized measurement companies on TenneT's website.

When it comes to energy, you also need a supplier. Because these parties are only responsible for the transportation of energy; The energy itself comes from the side you choose.

Therefore, these three components (connection, measurement and energy supplier) are essential to get power to your brand new station.

The first bump is over. Now we move on to the next stage: a proper substation. You will need to change the high voltage provided by your grid operator later. Very few devices can operate properly at 10,000 volts. Therefore, this high pressure must be greatly reduced to about 420 volts. That's why you need a transformer. In this blog, you can learn more about the substation.

Such a transformer is nothing more than an oversized mobile phone charger installed in an area of a substation or compact substation. These substations come in many different sizes and designs, depending on the power of the transformer. Different suppliers also have different models. However, they must meet some requirements. Each network operator has its own station demand plan. Therefore, it is useful for your prospective suppliers to fully understand these different requirements. If the substation is unqualified, it will be checked by the installation personnel (iv-ER for short) and will not be turned on.

To prevent long-term prolapse, a suitable foundation must be built under the station. Then the station must be grounded. When all this is done, the station can be inspected by the network operator and put into use.

What should you look out for?

There are many things to do before you can implement the required connection. Finally, here are some tips so you don't forget anything:

Start early on to determine what kind of connectivity you need, and also think about the future.

Choose a measurement company and establish a connection.

Choose an energy supplier and establish contacts.

Find a transformer station supplier who will do all the work for you. For example, contact with the network administrator, station foundation, station foundation and so on.

Ensure that commissioning dates are known to all interested parties. If the party involved isn't ready, it can take weeks to make a fresh start.
