Summary

P321 proposes to publish information on the direction of delivery (delivering or offtaking) of Trading Units, particularly for each Grid Supply Point (GSP) Group, in each Settlement Period. This information can currently be obtained through Balancing Services Use of System (BSUoS) bills and Transmission Loss Multiplier (TLM) values. The Proposer is seeking this information to be explicitly provided to give customers better access to this information.

Progression

SmartestEnergy raised P321 on 1 April 2015. The Panel agreed to submit P321 to an Assessment Procedure, during which P321 was issued for the Workgroup’s Assessment Procedure Consultation. The Workgroup recommended that P321 should be approved, and its Assessment Report was presented to the Panel on 10 September 2015.

The Panel initially recommended that P321 should be progressed as a Self-Governance Modification and that it should be approved, and issued its Report Phase Consultation. The Panel made its final decision to approve P321 under Self-Governance on 8 October 2015 for implementation on 30 June 2016.

On 5 January 2016, the Panel wrote to the Authority to request the approved Implementation Date be deferred to 3 November 2016. The Authority approved this request on 26 January 2016.

On 9 June 2016, the Panel wrote to the Authority to request the approved Implementation Date be deferred to 29 June 2017. The Authority approved this request on 8 August 2016. P321 was implemented on 29 June 2017 as part of the June 2017 BSC Systems Release.
