Electronic communication

What are the requirements for electronic communication when applying for a licence?

One of the conditions you have to meet to obtain a license is that you meet the requirements for electronic communication for nominations, entry and exit programs, the portfolio imbalance signal and balancing actions.


You can exchange messages and communicate with us yourself. Your dispatch department does need to be reachable 24/7.

You could also opt to hire in a specialized company (service provider). If you want to make use of such a specialized company for the complete operational handling, you mus inform us about this. We need the name of the company and the contact person's details. The company will also have to take our communication test. If you only use the IT service of a service provider, you will have to do the communication test with us yourself.
