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.
