Customer Change Team Leader


This Change has been cancelled and was withdrawn by the proposer 


As part of the Switching Programme there is an intent to move the activities relating to creation and management of Market Participants within Market Domain Data (MDD) from the Supply Point Administrative Agreement (SPAA) into the Uniform Network Code (UNC). The intent will be for the UNC to direct the activities to be conducted by the DSC Agreement.


The primary aim of this XRN is to ‘lift and shift’ the current MDD Market Participant process from SPAA into the DSC. It may require formatting changes of the current SPAA table to align it to UK Link standard (to be outlined as part of capture). But the intent is not to redevelop or align to electricity at this stage.
