Formal title: Correcting an omission in the BSC arising from the P216 Alternative Modification legal text
We have identified that theP216 ‘Audit of LLF Production’ Alternative Modification legal text did not fully reflect the intent of the approved P216 Alternative Modification solution.
The P216 Alternative Modification introduced 16 principles for the calculation, audit and approval of Line Loss Factors (LLFs) to ensure that LLFs used in Settlement are accurate and consistent. These principles are documented in BSCP128 ‘Production, Submission, Audit and Approval of Line Loss Factors’. However, principle 15 was not correctly reflected in the P216 Alternative Modification legal text. As a result, the BSC does not allow the Panel (as delegated to the Imbalance Settlement Group (ISG) and the Supplier Volume Allocation Group (SVG)) to correct material manifest errors going back to the start of a BSC year.
On 2 August the Authority approved P261 and it was implemented on 9 August 2010.
