Data migration means that Balance Suppliers and Grid Owners transmit data from their systems to Elhub. This also includes improved quality control and quality assurance of the data.
The Elhub project has established and operates a central migration platform, Data Analysis and Migration tool (DAM), which Balance Suppliers and Grid Owners will upload exclusion of data from their systems at a specified file format for migration which is adapted Elhubs information model. DAM will analyze and assess quality of incoming data from Market Parties. In cases where data is considered incorrect, missing or inconsistent with other Market Parties, DAM will generate deviations files, Non-conformity files (NCF), back to the Market Parties. Market Parties must then work to correct errors and inconsistencies in their systems and correct these within the next upload.
The migration process
The migration to DAM starts February 2016 and continue until Go Live in 2017. This ensures data quality and consistency across Market Parties and in Elhub. In the process, Market Parties must pass Elhubs milestones: //elhub.no/nb/test-og-migrering/akt%C3%B8rmilep%C3%A6ler. The detailed migration process is specified for each milestone.
Principles of the migration process:
The quality of migration data is metered by several milestones. At each milestone data is transmitted in two iterations so that Market Parties are given the opportunity to increase their data quality.
- Incomplete removal of the entire data set, including history; about a month before each milestone
- Delta extraction (changes and additions from the fullest exclusion) prior to the milestone
Small Market Parties (less than 5,000 metering points) are authorized to submit full data for basic data and structure data in each iteration (these will not have to implement delta-functionality). For metered data, only new or changed data since the last iteration is submitted for the small Market Parties.
