Formal title: New charging code structure for Unmetered Supplies
The Supplier Volume Allocation Group (SVG) requested that Elexon investigate potential amendments to the current Unmetered Supply (UMS) arrangements, in order to recognise newly developing control technologies, known as Central Management Systems (CMS). As part of this work, an external review group was assembled which considered a number of solutions, which were presented to the SVG in paper SVG72/01. One of the options proposes that the structure of the UMS charging code be changed to facilitate CMS technology. CP1204 proposes extending the charging code structure to 13 digits, and involves changes to BSCP520. The proposed extension of the Charging code structure will increase accuracy as the present code may lead to inaccuracies in Settlement because it cannot accurately reflect the operation of new, more dynamic apparatus.
CP1204 was raised from DCP0002 ‘New charging code structure for Unmetered Supplies’. CP1204 was raised on 6 July 2007. CP1204 was issued for Industry Impact Assessment as part of CPC00609 on 6 July 2007. CP1204 was presented to the SVG on 4 September 2007 for a decision on Progression. The SVG approved CP1204 for inclusion in the June 2008 Release. CP1204 was implemented on 26 June 2008 as part of the June 2008 BSC Systems Release.
