SEC Newsletter April 2018

Good afternoon,

Welcome to the new financial year, and for some of the SEC Sub-Committees, that means a new round of member nominations and elections.

The Sub-Committees play an invaluable role in ensuring the Panel are supported to deliver the SEC Objectives; the first of which is to facilitate the efficient provision, installation, and operation, as well as interoperability, of Smart Metering Systems at Energy Consumers’ premises within Great Britain.

So, what do the Sub-Committees do? Perhaps that’s best illustrated by looking at an example such as the current work being undertaken to introduce SMETS1 Services into the DCC.

The Testing Advisory Group have spent significant time developing and recommending the approach to testing the SMETS1 solution that will ultimately be deployed. The SMKI PMA and Security Sub-Committee are working together on updating the Security Architecture required to support these Devices, and considering the reuse of Keys. TABASC are planning how they will ensure the Technical and Business Architecture Documents and Model will be updated to reflect the changes introduced with this new functionality. And once the Services are up and running, it will be the Operations Group that monitors and reports to the Panel on how those Services are being delivered.

If you want to be part of shaping the development, implementation or operation of key pieces of work like these, please keep an eye out for upcoming calls for nominations to be a Committee member.

Nominations for Security Sub-Committee members were opened on 30th April 2018. Please consider applying and keep a look out for the voting process that will follow.


Best Regards,

Courtney O’Connor

  • a list of issues that have been agreed as out of scope for the BEIS Issue Resolution Process, and passed over for progression via the SEC Modification Process.

Testing Advisory Group (TAG)

The TAG met on 25th April 2018 to primarily discuss:

  • the DCC’s proposal for SMETS1 Migration Testing and System Capacity Testing;
  • the DCC’s proposed changes to the Release 2.0 Device Integration Testing and User Integration Testing Approach Documents, in light of recent developments and associated Release 2.0 plan changes associated with the availability of SMETS2 v3.0 devices for DIT. The TAG agreed that the proposed revisions to these documents accurately reflected the associated proposals; and
  • the initial details on the scope and activities for the June 2019 Release, including the approach and content of associated testing documentation.

Smart Metering Key Infrastructure (SMKI) Policy Management Authority (PMA)

The SMKI PMA met on 17th April 2018 and the following topics were discussed:

  • The SMKI PMA discussed DCC remediation actions to address a SMKI-related Severity 2 incident. The incident relates to SMKI Certificates having leading zeros in the signature ‘blob’ of the SMKI Certificate that subsequently fails validation when latest versions of Java are installed. The SMKI PMA agreed that the current Section L governance arrangements for DCC access to the SMKI Repository may need amendment.

The next SMKI PMA meeting is scheduled for 15th May 2018.

The next Ops Group meeting will be held on the 22nd May 2018.
