Reconciliation is a process which follows the allocation process. The objective is to compare the volume that has been assigned to a supplier during the allocation process with the actual consumption. This comparison is made based on the meter readings from the end consumer (in general collected once a year). This difference is used to settle the final energy consumption correctly between suppliers.
Reconciliation is a volume correction per supplier, calculated over a period of one calendar month. By means of the reconciliation process, suppliers get ‘assigned’ ultimately the energy volumes as read on their customers’ meters.
The market parties have agreed to implement a common model for the reconciliation volume calculation for the three regions. The principles of the new volume process are described in a UMIR document(link is external), approved by the market parties and the respective regional regulators.
