A new Market Role ID is required for TSO as TSO is a valid recipient of market messages. At present there are only two

values, one for DSO (to incorporate all of Networks) and one for SSA. This will be used to populate Recipient ID which

appears in the Header segment of market messages.

In addition – the Recipient ID field in the Header will also require to be populated with Generator Ids – i.e. the same

contents as the Generator MPID without the last char. For example where the Generator MPID is D04G then the Generator

ID should be D04.
