Approval of CP1594 for Implementation on 27 June 2024

On 7 May 2024, the Supplier Volume Allocation Group (SVG) and Imbalance Settlement Group (ISG) approved BSC Change Proposal (CP) CP1594 ‘Creating an Approval Process for New and Legacy Communication Types’ for implementation on 27 June 2024 as part of the standard June 2024 Release.

What is the approved solution?

The solution will involve creating an approvals process similar to the Compliance and Protocol Approval procedure found in BSC Procedure (BSCP) 601 ‘Metering Protocol Approval and Compliance Testing’, focusing on updating metering communication technologies. This initiative intends to simplify introducing new communication methods and phasing out old ones.

CP1594 seeks to establish a central management process for communication methods without immediately purging existing data methods, except for the planned discontinuation of Circuit Switched Data (CSD) and Public Switched Telephone Network (PSTN) by the end of 2025, to reduce impact on participants and allow a streamlined review post-implementation.

Who will be impacted?

CP1594 is expected to affect:
• Suppliers
• Generators
• Data Collectors
• SVA Half Hourly Market Operator Agents (HHMOAs)
