Summary

This Modification will enable individual consumers to be supplied by multiple Trading Parties through a Balancing and Settlement Code (BSC) Settlement Meter at the Boundary Point. It will amend the market rules to support development of non-traditional business models and innovation, expanding upon the solution to be implemented by BSC Modification P344 ‘Project TERRE implementation into GB market arrangements’. It will achieve this through the creation of a new Party Agent role, the Customer Notification Agent (CNA), who would reconcile power flows through the Settlement Meter, enabling accurate allocation of volumes and costs, which in turn will allow Trading Parties to reflect these volumes in their bills and payments to consumers.

This Modification is Proposed by New Anglia Energy, a recent BSC entrant who will be an Exempt Supplier, but the principle behind it has support from a range of BSC Trading Parties including OVO Energy and Cooperative Energy, and non-BSC parties, including Powervault and Verv.

Progression

The fourth P379 Workgroup was held on 21 May 2019 at ELEXON’s offices.  The group discussed how balance responsibility could work under the P379 solution. To simplfy consideration on balance responsibility the previously discussed use case 2 was split into 2A and 2B with the WG providing views on proposed solutions. The meeting also covered items to be included in the P379 Interim Report to be presented at the June BSC Panel meeting. This will include key WG discussions and a recommendation of how the Modification should progress. The next meeting to conclude balance responsibilty use cases and discuss the Party Agent Role is scheduled for June 2019. The exact meeting date will be confirmed in the next few weeks.

The second P379 Workgroup was held on 3 April 2019. The group discussed the Issue and scope of P379. The WG considered the  Electric Vehicle Use Case solutions. Ofgem provided a presentation on access and forward looking charges SCR. The WG briefly discussed Exempt Supply Use case and is to complete discussions on the proposed solutions. As a result, a teleconference meeting was held on 18 April 2019 to finish the Use Case discussions. ELEXON will then look into developing the Workgroups preferred solution and business requirements.

P379 was raised on 3 January 2019, and the Initial Written Assessment (IWA) was presented to the BSC Panel at its meeting on 10 January 2019. The Panel progressed P379 to the Assessment Phase. The first Workgroup meeting for P379 was held on 27 February 2019. The group agreed the Terms of Reference and discussed views on the proposal.
