ACER’s data quality assurance at a glance
ACER is committed to ensuring high-quality transaction and fundamental data reporting, and will continue to devote specialist supervisory efforts to this endeavour to further advance its market monitoring capabilities.
As part of its data quality framework, ACER assesses and ensures the data received under REMIT and the Implementing Acts are complete, accurate and timely. These data quality assessments are performed regularly on different data sets, covering transactions executed either at different organised market places or bilaterally.
The REMIT data quality assurance is based on a
1. Data collection stage
During the data collection stage, data is inserted into the ACER's REMIT Information System (ARIS), where the validation rules are applied to the data.
There are two levels of data validation: the first is performed on a technical level, while the second, more in-depth, is managed at the database level. Here, integrity checks are undertaken across the reported and reference data. Any invalid data is rejected and flagged.
Data validation ensures the quality of the collected data, so they can be stored in ACER's REMIT database.
2. Data quality assessment stage
The data quality assessment stage applies other methods to confirm the quality of the data and ensures a timely follow-up.
Non-compliant data at either stage can lead to the enforcement of Article 8 of REMIT. ACER seeks to solve any data quality issues by cooperating with reporting parties, but enforcement action will be initiated if necessary.
