New Draft Proposals

One new Draft Proposal has been raised since the last newsletter. You are invited to provide feedback to the Change Team to help us understand whether the issue affects your Party.


DP178 ‘Removing DSP validation against the SMI join status for SR8.8.x’


Download the request for information here


The on-site Device Installation and Commission (I&C) process fails when the Data Service Provider (DSP) does not receive successful messages for joins of Service Reference Variants (SRVs) 8.7.x. This prevents the Service User from being able to send an ‘Unjoin’ command. This is because the business validation on the SRV commands 8.8.1 ‘Unjoin Service (Critical)’ or 8.8.2 ‘Unjoin Service (Non-Critical)’, check that a Device is joined to the Smart Metering Inventory (SMI) to allow it to be un-joined. This results in Devices failing the I&C process which must then be fixed by manually updating the SMI database at a cost of £2,000 per correction.


Modification Report Consultations closing next week

Two Modification Report Consultations will close on 16 August 2021. SEC Parties are invited to share your comments before the Modification Proposals are taken to the next Change Board meeting, when a final decision will be made. For more information, and to respond to any of these consultations, download the relevant consultation pack linked below and send your response to the Change Team.


SECMP0024 ‘Enduring Approach to Communication Hub Firmware Management’


Download the consultation here


The Proposer advises that nothing is in place to automatically notify Suppliers once firmware updates have been activated on Communications Hubs (CHs). The Proposer also considers there to be a need for a formalised process to manage firmware updates to CHs between the DCC and Suppliers. The Proposed Solution seeks to implement a new DCC Alert that will be sent to Suppliers upon firmware being activated on Communications Hubs. This Alert will contain the Communications Hub firmware version.



MP104 ‘Security Improvements’


Download the consultation here


DCC Users are required to Digitally sign XML format Service Requests and sign Pre-Commands with a User Role Signing Private Key. That Key must be a separate dedicated Key that must not be used for communication with Devices. The Security Sub-Committee (SSC) is concerned that Keys could be used incorrectly. However, without the means to validate the use of separate Keys, there is no way to monitor if or how frequently this occurs, and no way to advise Users to enable them to ensure they are compliant with the SEC.

The solution is to implement a DCC validation check to identify if this is occurring and, if necessary, work with DCC Users to ensure compliance.


New Refinement Consultation

There is one Modification Proposal undergoing Refinement Consultation which is due to close on 3 September 2021. As a SEC Party, you can help influence the Proposed Solution, help determine the business case for the change, and comment on how the proposal will affect your organisation. For more information and to respond the consultation, download the consultation pack linked below and send your response to the Change Team.


MP122B ‘Operational Metrics – Part 2’


Download the consultation here


A need to improve transparency and relevance of measures contained within the DCC Performance Measurement Report (PMR) has been identified. In its monthly review of the PMR, the Operations Group has found it increasingly difficult to report to the SEC Panel on the issues within the report.

As a result of the issues encountered, the Operational Metrics Review (OMR) was undertaken to better understand the PMR measures, consider amendments and recommendations of new performance indicators. Through workshops and User surveys, Users want to see reporting that reflects the business processes that the DCC supports.


Technical Specifications for the November 2021 SEC Release

You can now find drafts for each of the Technical Specifications to be implemented in the November 2021 SEC Release published on the release webpage here. The draft Specifications include mark-up to text, commentary identifying which Modification implemented the change and, where applicable, which Issue Resolution Proposal (IRP) the changes came from.


These documents currently reflect the approval of SECMP0007, MP090, MP105, MP150, MP158 and the anticipated approval of DP164. If you have any questions, please contact the Change Team.
