New XML messages will be introduced in Theme release 2021 (TR2021) – Tranche 1 of the Allocatie 2.0 programme. Metering responsible parties, balance responsible parties and (facility) grid operators must exchange these messages with TenneT. In order to do this, you must first perform a number of tests and then complete a qualification process. You must contact TenneT as soon as possible in order to complete Connection and Semantic tests. TenneT will coordinate these tests. The User Acceptance Tests (GAT) will be centrally coordinated by NEDU.



TR2021 (or Tranche 1) of the Allocatie 2.0 programme is in full flow. To kick things off for market participants, we presented a very busy online information session on 23 March 2021. The presentation and all other documentation can be found on mijnNEDU (under ‘Release’, ‘TR2021 tranche 1 A2.0’)’.

Compulsory testing and qualification
The Market-Market-Communication (MMC) Hub by TenneT is part of TR2021. TenneT will use this hub to exchange new XML messages with market participants. In accordance with legislation (established by the The Netherlands Authority for Consumers and Markets (ACM) in article 13.33), you can only use these messages once TR2021 has been implemented. Before you can do this, you must undergo several Connection and Semantic tests at TenneT. The GAT and the compulsory qualification process will follow in January 2022. If you do not undergo qualification, you will not be able to exchange messages with TenneT in the future.

Metering responsible parties, balance responsible parties and facility grid operators
TenneT would like to contact market participants, who intend to use these XML messages, as soon as possible. This relates to the following parties:

  • All metering responsible parties (MRPs/dutch: MV)
  • Balance responsible parties (BRPs/dutch: PV) that have been ‘fully’ approved
  • Balance responsible parties that do not have any connections, but intend to realise them
  • Facility grid operators (FGO/dutch: FNB) for closed distribution systems (GDS)

Contact TenneT as soon as possible
You can pass on your contact details via allocatie2@tennet.eu. TenneT will then contact you to coordinate the planning for the Connection and Semantic tests. This will allow your organisation to smoothly connect to the MMC Hub and TenneT’s testing and qualification platform (TQF). Also check out the testing and qualification guide on mijnNEDU (under ‘Release’, ‘TR2021 tranche 1 A2.0’, ‘Testing’ folder, ‘Testing MMC hub (English)’ sub-folder).

Types of messages
The testing and qualification process relates to the following messages:
