Issue 115 – Barriers to Distributed Energy Resource Registration in the Balancing Mechanism

To prevent double-counting in the Balancing Mechanism (BM), Modification P344,  requires Suppliers and Virtual Lead Parties (VLPs) to notify their Supplier Volume Allocation Agent (SVAA) of Meter System ID (MSID) Pairs (both Import and Export MSIDs). This creates challenges for Suppliers who may have different Import and Export Suppliers at a single site, leading to compliance issues. Additionally, the current AMSID registration process, with its three-stage manual validation, is inefficient for bulk updates and restrictive with regard to automation.

The proposed solution aims to streamline asset registration by using APIs and reducing manual steps for efficient updates. It also clarifies BSC rules on MSIDs to prevent double-counting, potentially allowing separate management of Import and Export MSIDs or giving a single BSP control over both.
