Formal title: Amend the three digit numeric Line Loss Factor Class (LLFC) Id to an Alphanumeric LLFC Id

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


CP1434 proposes to amend the format of the Line Loss Factor Class (LLFC) Identifier (ID) from a three-digit integer value to a three-digit alphanumeric value (consisting of the digits 0-9 and the capital letters A-Z excluding I and O). This will increase the number of LLFCs from 999 to 39,303.


CP1434 was raised by Scottish and Southern Energy Power Distribution on 16 February 2015 and has been issued for CP Consultation.

At its meeting on 28 April 2015, the SVG recommended by majority that CP1434 should be deferred and a CP Workgroup established to explore other options. At its meeting on 14 May 2015, the Panel agreed to defer a decision but elected to issue an industry Request for Information to seek answers to the SVG’s questions.

At its meeting on 2 June, the SVG recommended by majority that CP1434 should be rejected. The Panel approved CP1434 at its meeting on 11 June 2015 for implementation on 30 June 2016 as part of the June 2016 BSC Systems Release.
