Registering for participation in data exchange

This page is about participation in system processes. Here you can find out who participation is intended for, how the registration process works and what preparations are required.

Since the Energy Act entered into force 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 the data exchange or modify an existing participation? You can arrange this via Het Normo.

Het Normo manages participation in the data exchange between market parties in the energy sector. The link below will take you to the Het Normo portal, where you can submit an application to participate in the data exchange or modify your existing participation.

This page is intended for organisations that want to perform a new market role in the energy market and thus need to access data exchange for system processes. To receive final approval for participation, you may also need to request a market role confirmation, licence or designation from the responsible organisation.

How does it work?

During the registration process, we will agree which data exchange is in keeping with your role and activities in the energy market. Access is evaluated and registered by Het Normo. EDSN ensures the technical connection, the testing environment and the qualification process.

Step 1. Information and registration

Step 2. Connection to the central systems

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).

Step 3. Testing and qualification

This step involves preparing the qualification process that you will perform in the testing environment. This qualification process allows new parties to demonstrate that their local system is suitable for correctly and comprehensively exchanging information with the central systems of EDSN. We will also examine if you possess enough knowledge about the processes in the energy market.

Step 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.

Step 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.

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.

1. You must be familiar with existing agreements within the sector

The following documents are important when preparing for the participation process. This information is part of the responsibilities that accompany your new role in the energy market. Please read them carefully:

• Information Code Electricity and Gas
• Market agreements and processes of Het Normo
• Only for Other Service Providers: Code of Conduct for OSPs

2. Apply for market role confirmation to operate as a party in the energy sector

A market role confirmation can only be obtained by registering with one of the organisations below. Below we have shown which organisation needs to be contacted for each market role. This registration can be performed simultaneously with your registration at Het Normo

3. Determine who will occupy the role of administrator within your organisation

You will be asked to provide your contact details when you start the registration process. The person that submits the form will become the contact person and administrator for the organisation, with regard to applications that the market party will use in the testing environment as well as during normal production.

An administrator account can be created via the Secure Access Service (DVT). This is a new way of logging into services that EDSN supplies on behalf of the joint system operators. The Secure Access Service means that, in the future, you will only need one account to log into the EDSN services that you are entitled to access.

Your administrator for the Secure Access Service (DVT) is responsible for user management within your own organisation. The administrator will be authorised to create users in the DVT and to link application roles to users, so they can access the applications of EDSN.

4. Request eHerkenning

In order to register, you will need eHerkenning with reliability level 3 (eH3).

eHerkenning is a means of digital encryption that allows organisations to securely log into government bodies and service providers. It is a verification tool that you must request from commercial providers and can be used to confirm your current identity.

More information about eHerkenning can be found on this page.

Why must I register?

You must register as a new market party if you want to perform a role in the energy market that requires participation in data exchange for system processes. Such access can be requested via Het Normo. Het Normo will evaluate and register which role and data exchange your organisation is able to access.

The whole registration process consists of several parts. Technical connection to central systems, the testing environment and the qualification process will take place via EDSN, on behalf of the joint system operators. For some market roles, you must also request a separate accreditation, licence or designation from the responsible organisation.

Why must I register via Het Normo?

Het Normo has been managing the registration process for participation in data exchange for system processes ever since the Energy Act. That is why new access is requested, or existing access is modified, via Het Normo.

Het Normo will evaluate and register which organisations are afforded access, for which roles and for which data exchange. Other parts of the whole registration process, like the technical connection, the testing environment and the qualification process, take place via EDSN on behalf of the joint system operators.

How must international parties register?

If your organisation is not based in the Netherlands, please use this registration form. Please fill in the details as fully as possible and then contact us via the Marktloket (service desk).

What are system processes?

System processes are processes in the energy market where market parties exchange data with each other and with central systems. This data exchange is needed in order to effectively perform roles in the energy market, e.g. in market processes where connection, registration, qualification and data services are needed.

Het Normo manages the registration process for participation in this data exchange. EDSN offers technical support, like when connecting to systems and testing the data exchange.
