Data storage period
Data is stored in Datahub as necessary to meet the needs of parties’ processes. However, data cannot be stored in Datahub indefinitely. The storage period for metering data in Datahub’s operative database is six years, and this time also steers the storage of data that has become obsolete with regard to other processes. When a customer’s agreement ends, the customer and agreement information are removed from Datahub’s operative database after the same six-year period when the last metering data for the customer is deleted. Agreement information also includes invoice row data for the agreement to be deleted. Customer information includes all information directly concerning the customer, such as customer authorization information. Accounting points with status ‘removed from use’ will be removed too, if they have no related agreements. The figure below presents the process which is used for removing historical data from Datahub, as described above.
Anonymised and aggregated statistical data on metering data is nevertheless stored even after this six-year period ends.
