Formal title: Audit of LLF Production
P216 seeks to provide additional transparency and consistency regarding the calculation and application of Line Loss Factors (LLFs) used in Settlement by: •creating a set of high level principles, which all LLF methodologies (created by Distributors) must adhere to (these principles will sit in a BSCP); •requiring an audit of the methodologies used to calculate LLFs to ensure that they are consistent with the principles; •requiring an audit of the calculation of LLFs to ensure that they are consistent with the audited and approved methodology; •conducting spot checks to confirm that the correct LLFC has been applied at a Metering System level; and •not allowing changes to LLFs during the year (except in limited circumstances).
BSC Panel’s recommendation was that the Proposed Modification should not be made and the Alternate Modification should be made. The Authority approved the Alternative Modification on 24 April 2008. P216 was implemented on 20 April 2009 as a stand alone release.
