Testing in the Nord Pool - Member Test environment (MT)

Important Notice
Nord Pool has improved the handling of multi-resolution portfolios, now supporting 15, 30, and 60-minute MTUs,
- As of the start of the Joint Member Test begins on 7 April 2025: All portfolios automatically support multi-resolution MTUs (15, 30, and 60 minutes). This functionality will also apply in production at the SDAC 15-minute MTU go-live.
- In MT, prior to the start of the Joint Member Test: Previously to test QH auctions with a 15-minute resolution, you were asked to contact support@nordpoolgroup.com to enable your portfolios (this is no longer requred). The temporary restriction requiring a fixed MTU per portfolio has now been lifted in Member Test.
