MP143 Incorporating IRPs into GBCS v3 series

Proposer Jen Boraston
Lead Analyst Kev Duddy
Date raised 21/09/2020
StageRefinement Process
Implementation date Not yet determined
Latest update SECAS has requested a DCC Preliminary Assessment on 7 September 2021.

What is the issue?

MP098 'Incorporation of multiple Issue Resolution Proposals into the SEC - Batch 3' was implemented in the November 2020 SEC Release. It incorporated 20 non-Data Communications Company (DCC) System impacting Issue Resolution Proposals (IRPs) into the GB Companion Specification (GBCS) v4.0 and Smart Metering Equipment Technical Specifications 2 (SMETS2) of that release.

During the development of MP098, there was no material benefit to implement the 20 IRPs into the GBCS version 3 series. SEC Parties would like the option to incorporate these 20 IRPs into the GBCS v3 series as and when a material change necessitates an uplift to the next GBCS v3.x.

What is the solution?

The Proposed Solution was originally to incorporate these 20 IRPs into the GBCS version 3 series as and when a material change necessitates an uplift to the next GBCS v3.x. MP143 is the only modification seeking an uplift to the GCBS version 3 series.

Following feedback from TSIRS and Device Manufacturers this has now been amended to implement only 4 IRPs that are required to remain compliant with the Commercial Product Assurance (CPA) scheme.
