Since the FAQ meeting, Energinet has been in close dialogue with both Evida and Nordion, to map what has been causing the data quality to be poor, and how to resolve the identified issues. One general finding is that the focus right after 1 October mainly have been on getting the models and systems to work, and not primarily on data quality. This focus has now changed. Secondly it has been clear that there is not one single reason for poor data quality, which makes it harder to identify and solve the issues.

To be concrete, the following focal points have been identified in terms of data quality, and are split up into what is the status, what is expected to be resolved with in the coming weeks, and what are more long-term:

Current status:

• General higher awareness and focus on possible reasons causing poor data quality, and focus on faster resolving
• Several issues have already been identified and resolved during the first phase
• Start-up challenges going over to Edigas communication between Evida and Energinet are resolved
• Improved data estimations since 1 October
• Specific focus in improving nDMS within-day data, and what is causing especially large flaws in data (e.g. zero values on all data for 1 or more full distribution areas)

Expected resolved within coming weeks:

• General: a more stable operation will release time and resources which will improve the observation of the systems which can result in a more proactive approach to resolving issues
• Minimizing the situations where zero values a forwarded for 1 or more areas for nDMS values

Expected resolved by end 2022:

• Faster identification (manual focus and automatic control mechanisms) and resolving if nDMS data are missing
• Better replacement data if nDMS data is missing
• Better control mechanisms to catch “outliers” both on DSO and TSO/BAM level

General status of the balancing model

Since FAQ meeting, the following issues have been resolved:

• Calculation and allocation at Causer Allocation Point (CAP) based on Individual Shipper Balance (ISB) instead of IASB
• Issue with matching between Gas Storage Denmark and Energinet.
• Yellow zone trade prices not published on online portal

The following items are still to be resolved:

• Relevant data published on Energi Data Service (Balancing prices, public data, ASB and green zone limits)
  • Expected to be resolved stepwise until end 2022, with balancing prices as first priority
• (Re)introducing the non-valid allocation after the gas day at 11:15
  • Expected to be resolved by end 2022
