CP1589 ‘Create Additional Market Participant Role Codes’

Market Participant Role Code’ is a single character alphanumeric value which is used as a unique identifier for certain Market Roles. There are 36 possible Role Codes to be allocated to different Market Participant Roles, which are defined in the Market Domain Data (MDD). In order for new Market Roles to be created in the future, a change to the format of the ‘Market Participant Role Code’ Data Item is required to increase the number of available Role Codes. Moving to a two-character alphanumeric value would provide hundreds of new potential Market Participant Role Codes.

CP1577 ‘To clarify the sending of a D0151 is required for all COS NHH loss processes’

BSCP504 requires the outgoing supplier to send a D0151 to terminate their NHHDC appointment on Change of Supply. The positioning of clause 3.2.6.4(a) implies this is only required for non DCC serviced metering systems, whereas this should be a requirement for all metering systems. This CP amend BSCP504 to clarify that 3.2.6.4(a) applies to all Metering Systems.
