CP1547 ‘Clarification on Site Specific LLF Calculation Process for Embedded LDSOs’

Formal title: Clarification on the Site Specific Line Loss Factor Calculation Process for Embedded Licensed Distribution System Operators

CP1547 seeks to provide clarity for Embedded LDSOs that choose to calculate Site Specific Line Loss Factors rather than Mirroring, through updates to BSCP128. 

Usually Embedded Licensed Distribution System Operators (LDSOs) would Mirror the Line Loss Factors (LLFs) of the Host LDSO. However, as Embedded LDSOs are beginning to calculate Site Specific LLFs, Elexon has been made aware of some confusion over the process and timelines for these calculations. This confusion indicates that additional clarity is required for Embedded LDSOs moving from generic LLFs to Site Specific LLFs. 

This CP proposes to make changes to BSCP128 ‘Production, Submission, Audit and Approval of Line Loss Factors’, which details the methodologies for calculating and auditing LLFs, to provide more clarity for Embedded LDSOs undertaking these calculations.
