Modification: P355

Introduction of a BM Lite Balancing Mechanism

Proposer: PeakGen

Current Phase: Assessment Procedure

Lead Analyst: Claire Kerr

Category: Settlement

Implementation Date: TBC


P355 seeks to introduce a new BM Lite classification to allow smaller generators to offer energy to the System Operator for energy balancing, in competition with the larger BM Units already in the market.


P355 was raised by PeakGen on 21 June 2017. The Initial Written Assessment was presented to the BSC Panel at its meeting on 13 July 2017. The first Workgroup meeting was held on 2 August 2017. The second Workgroup meeting was held on 20 September 2017. The third Workgroup meeting was held on 23 October 2017.

The P355 Proposer recently contacted ELEXON to confirm that he believed that the Virtual BM Unit element of the P344 solution covers much of what was intended by P355. The Proposer therefore requested that any further work for P355 is put on hold until June 2018, when the Draft Modification Report for P344 is presented to the BSC Panel. At its meeting on 14 December 2017, the BSC Panel approved a three-month extension to the P355 timetable until June 2018. P355 is now on hold, meaning that no further Workgroup meetings will be held before this time.
