P350: Consultation on Methodology for Load Periods and Sample Settlement Periods 19 June 2018


Who will this impact?

Modification P350 ‘Introduction of a seasonal Zonal Transmission Losses scheme’ introduced a Transmission Loss Factor (TLF) for each TLF Zone and BSC Season, so transmission losses can be allocated on a geographical basis. P350 went live on 1 April 2018.

This Consultation details the proposed methodology for setting Load Periods and Sample Settlement Periods to be used in the derivation of Zonal TLFs, as required by the Balancing and Settlement Code (BSC).

We encourage you to respond to this consultation using the consultation pro-forma. The consultation period will end on Tuesday 03 July 2018 at 17:00. Please return responses to: [email protected].

At the end of the consultation period, Elexon will consider all responses and, if required, update the methodology accordingly. The methodology, along with all consultation responses, will be presented to the Imbalance Settlement Group (ISG) meeting in July to request approval of both the methodology and actual LPs and SSPs.

Upon approval, Elexon will publish the actual LPs and SSPs on the website on or before 31 August 2018.
