Participation in data exchange
Partners in Energy supports market participants in their services within the energy sector. On this page, you can read more about registration, data management and participation in data exchange.
With the Energy Act coming into effect on 1 January 2026, the management of participation in data exchange within the energy sector has been transferred to Het Normo. Would you like to participate in data exchange or change your existing participation? You can arrange this via Het Normo.
Het Normo manages participation in data exchange between market participants in the energy sector. The link below will take you to the Het Normo portal, where you can submit an application to participate in data exchange or change your existing participation.
The registration process consists of five steps. The average duration of the entire process is between 4 and 6 months. You can read more about these steps below.
Process for Participating in Data Exchange
Step 1. Information and registration with Het Normo
The first step involves registering with Het Normo. This can be done by completing the registration form. It is only possible to do this if you have eHerkenning. Read more about eHerkenning.
Step 2. Connection to the central systems of the joint grid operators (EDSN)
This step involves realising the connection between your organisation’s local system and EDSN’s central systems. Once all your details have been received, we will realise the connection within three weeks. You will then immediately receive your login details for the testing environment(s).
Stap 3. Testing an qualification of the joint grid operators (EDSN)
In this step, you prepare the qualification that you will perform in the test environment. This qualification means that, as a new party, you can demonstrate that your decentralised system is capable of exchanging correct and complete information with EDSN's central systems. We also check whether you have enough knowledge of the processes in the energy market.
Stap 4. Formal completion of registration
When registering to participate in data exchange at Het Normo (step 1), did you opt for a provisional registration because you did not yet possess a market role confirmation? Then we will finalise your application once you possess the required market role confirmation, licence or designation. Therefore you need eHerkenning level 3. Read more about eHerkenning.
Stap 5. Entering the energy market
You have successfully completed the qualification process and possess the required market role confirmation. In this step, we will record your registration for participation in the data exchange in the central systems. We will also inform transmission and distribution system operators about your registration. You will join the energy market after ten working days. From that moment onwards, you will be able to perform your activities under your new market role.
Arrange in advance
Before you register, it is important for you to be aware of the existing agreements within the sector. You must take care of a few things in advance. This will allow us to process your application expediently.
