SEC version 61.0 came into effect on 30 June 2022 to implement the June 2022 SEC Release. This included six Modification Proposals and changes made by the Department for Business, Energy and Industrial Strategy (BEIS) to support the Enduring Change of Supplier (ECoS) arrangements.
Summary of SEC modification changes
SECMP0015 ‘GPF timestamp for reading instantaneous Gas values’: Only the DCC User Interface Specification (DUIS) and Message Mapping Catalogue (MMC) document changes required for SECMP0015 have been implemented, alongside other DUIS and MMC changes. The functionality, including the DCC System and Data Services Provider (DSP) System changes, and the associated changes to the remaining technical specifications will not be implemented until the November 2022 SEC Release (3 November 2022). Therefore, there will be no User impacts resulting from SECMP0015 in the June 2022 SEC Release.
In the November 2022 SEC Release, SECMP0015 will allow Parties and Devices reading the instantaneous values from the Gas Proxy function (GPF) to know the time on the Gas Smart Metering Equipment’s (GSME’s) clock when the value was provided.
SECMP0024 ‘Enduring Approach to Communication Hub Firmware Management’ has introduced a new DCC Alert that will be sent to Suppliers upon firmware being activated on Communications Hubs which contains the Communications Hub firmware version.
MP104 ‘Security Improvements’ has implemented a new DCC validation check to identify if DCC Users are Digitally Signing Extensible Markup Language (XML) format Service Requests and Signed Pre-Commands with a User Role Signing Private Key.
MP159 ‘Credit Cover Review’ has addressed inefficiencies within SEC Section J3 ‘Credit Cover’ and has added clarity to the areas that have been previously misinterpreted.
MP195 ‘Security Sub-Committee guidance on Device Assurance’ has added an obligation on the Security Sub-Committee (SSC) to develop and maintain a guidance document for Device security assurance.
MP199 ‘June 2022 SEC Release Supporting Changes’ has made minor additions and amendments to the DUIS which would ensure greater clarity.
ECoS-related changes
The ECoS-related changes impact SEC Appendix AB ‘Service Request Processing Document’ (SRPD) and SEC Appendix AD ‘DCC User Interface Specification’ (DUIS). The nature of the ECoS-related changes being for the June 2022 SEC Release is technical, and essentially reflects additional checks that the DCC will be carrying out on Service Requests and Signed Pre-Commands to ensure that they will be successfully processed by Devices. The detail of these additional checks can be found in the BEIS designation letter check in the link below.
