CP1599 Remove the requirement in BSCP602 to specify the Half Hourly Data Aggregator in Non-Final Demand Declarations
Formal title: Remove the requirement in BSCP602 to specify the Half Hourly Data Aggregator in Non-Final Demand Declarations
CP1599 proposes to amend BSCP602 to remove the requirement that Non-Final Demand Declarations specify the HHDA and HHDA Effective From Date (EFD) for each MSID. It also proposes to add details of the process used by the Customer Solution to identify whether a MSID stored in the SVA Metering System and Asset Metering System Register has been migrated to the MHHS arrangements or not, and to validate the MSID appropriately and to retrieve and store the relevant information for that MSID.
BSCP602 ‘SVA Metering System and Asset Metering System Register’ requires that Non-Final Demand Declarations specify the Half Hourly Data Aggregator (HHDA) appointed to each Import Metering System Identifier (MSID) and Export MSID.
The Elexon Kinnect Customer Solution ‘Non-Final Demand Declarations’ page and the Elexon Website ‘Non-Final Demand Declarations’ page also include the Half Hourly Data Aggregator (HHDA) as a mandatory field to support the BSCP602 requirement.
However, from the beginning of the Market Wide Half-Hourly Settlement (MHHS) Transition Period, HHDAs will not be appointed to MSIDs that have been migrated to the MHHS Arrangements, so it will not be possible to specify the HHDA for all MSIDs registered in the Customer Solution’s ‘SVA Metering System and Asset Metering System Register’ as part of Non-Final Demand Declarations.
Consequently, the obligation to specify the HHDA in Non-Final Demand Declarations should be removed from BSCP602, effective from the beginning of the MHHS Transition Period.
Note that amendments to the Customer Solution and the Elexon Website ‘Non-Final Demand Declarations’ page to facilitate the BSCP602 change are being carried out as part of Elexon’s Helix Programme, and the changes to BSCP602 are consequential.
