34. Retail Market Design Service Update
C. Madden, RMDS

35. Retail Market Design Service Update
Learning Point:
Change of Supplier Read Arrangements
A couple of Market Participants have submitted 010 messages in the recent past with Read Arrangement of SC or CR and a Required Date into the future
Market Participants should not populate the Required Date where the read type is SC
Market Participants need only populate the Required Date where the read type is CR and the reading is on the 010 message
010 messages with Required Dates well into the future will mean that the Change of Supplier process will wait until the date has been reached

36. Retail Market Design Service Update
Quality Review
Internal review of quality processes as well as Market processes ongoing
Stakeholder Meetings
Initial contact made with some Market Participants to arrange meetings in the next few weeks
Plan to be compiled following stakeholder meetings and submitted to CER following stakeholder meetings.
