We are gearing up for a new release: the May release 2027. No fewer than seven topics will go live next year. Metering responsible parties, suppliers and system operators (including operators of closed systems) will feel the impact most keenly. So make sure you prepare in good time and don’t miss our very first information session. It will take place on the morning of Tuesday 29 September.
What is the scope?
The May release 2027 consists of seven topics, four of which concern metering processes for large electricity connections. This is the scope:
- TS013A ‘Vertaalslag van meetgegevens naar allocatiepunt en/of overdrachtspunt (deel A)’ (‘Translation of metering data to allocation point and/or transfer point (Part A)’)
- TS013B ‘Vertaalslag van meetgegevens naar allocatiepunt en/of overdrachtspunt (deel B)’ (‘Translation of metering data to allocation point and/or transfer point (Part B)’)
- TS066 ‘OVP-volumes per overdrachtspunt’ (‘ISP volumes per transfer point’)
- TS080 ‘OVP-volumes grote aansluitingen delen met leverancier’ (‘Sharing ISP volumes for large connections with the supplier’)
- TS065B ‘Vereenvoudiging communicatie nettarieven kleinverbruik (deel B)’ (‘Simplification of communication regarding grid tariffs for small consumption (Part B)’)
- TS072 ‘Registratieproces submeetverantwoordelijken’ (‘Registration process for sub-metering responsible parties’)
- MB001 ‘Modernisering berichtstroom TMR’ (‘Modernisation of TMR message flow’)
Further information (in Dutch) can be found on the release page for the May release 2027 on the Energiedatawijzer.
Programme
During the information session, we will discuss the scope and schedule of the release and explain all the topics. This will provide you with a solid foundation for implementing the release within your own organisation. Here is an outline of the programme:
- Opening by the chair of the Integral Implementation Management Consultation (IISO)
- Scope and schedule of the May release 2027
- New and amended processes and messages based on the topics within scope, with explanations for each topic and market role
- Changes to the topics (Requests for Change, RFCs)
- You will, of course, have ample opportunity to ask the speakers questions. We will compile these questions into a Q&A, which we will publish at a later date on the Energiedatawijzer.
