Digitisation of Elections and Security Sub-Committee (SSC) Call for Nominations

Throughout the year SECAS holds elections for the SEC Panel and its Sub-Committees, where SEC Parties are invited to nominate someone, or themselves, for their Party Category seat. It is a great opportunity to contribute to and influence SEC governance, and to represent the interests of your Party Category. We have now digitised the election process so that it is even easier for SEC Parties to get involved. Instead of filling out paper forms, you can now make your nominations via our online form here.


The Security Sub-Committee (SSC) elections open on Friday 2 July 2021, with nominations closing at 5pm on 23 July 2021. You do not have to be a SEC Party to run, but you do need to be nominated by a SEC Party. The Party Categories for the SSC election are:


  • Three Large Suppliers
  • One Small Supplier
  • One Other SEC Party / Other User


SEC Parties will receive an email from SECAS with more information. If you have any questions, please contact the SECAS Helpdesk.


New Draft Proposals

Six new Draft Proposals have been raised since the last Newsletter. You are invited to provide feedback to help us understand whether the issue affects your Party. Please contact the Change Team to share your views.




DP170 ‘Firmware updates to Point to Point Alt HAN Devices’



The Alternative Home Area Network (Alt HAN) is being developed to address situations where one, or both, of the Gas Meter or In Home Display (IHD) are out of range, using Point to Point (P2P) Alt HAN Devices. Over-The-Air (OTA) firmware updates are used to deploy updates that either fix faults or provide new functionality to certain Devices.

The SEC facilitates OTA firmware updates to meters and the Gas Proxy Function (GPF) which is part of the Communications Hub. It also supports OTA updates for Devices like Prepayment Meter Interface Devices (PPMIDs) and HAN Connected Auxiliary Load Control Switches (HCALCS) but not for P2P Alt HAN Devices. This means any new functionality developed to deploy security updates or improve the service to consumers can only be deployed on site. The result is higher costs, longer timescales, and more inconvenience to the consumer than if an OTA firmware update could fix the issue.





DP171 ‘Undertaking a FUSA without a Supply Licence’



Following changes to licencing arrangements in 2020, prospective market entrants obtain their Supply Licence later in the onboarding process. Without a Supply Licence, Suppliers cannot undertake a Full User Security Assessment (FUSA), which is required to become a DCC User. This may extend the time between gaining a licence and being able to install and support Smart Metering for consumers.





DP172 ‘Reduced CPA & CPL requirements for innovation and Device field trials’


Currently, the requirements of the SEC are designed around the mass deployment of Devices and offer no leeway to support Minimum Viable Product (MVP) trials on the live DCC network. The biggest cost and risk blocker for the introduction of a new or modified Device type, or an innovative Device usage is the Commercial Product Assurance (CPA) arrangements.





DP173 ‘SMKI & DCCKI Document Set reviews’


The Smart Metering Key Infrastructure (SMKI) Policy Management Authority (PMA) has carried out a review of the SMKI and DCC Key Infrastructure (DCCKI) Document Sets as required by SEC Section L ‘Smart Metering Key Infrastructure and DCC Key Infrastructure’.





DP174 ‘Changes to Electricity pricing limitations within DUIS’


This Modification seeks to change the value range restriction of the BlockPrice and TOU Price Data Items within the DCC User Interface Specification (DUIS) which is required to allow more accurate prices. This proposal seeks to increase the number of decimal places that can be used. It would have no impact on what prices can be set.





DP175 ‘Alt HAN Inventory Information Sharing’



Distribution Network Operators (DNOs) and Meter Operators (MOPs) are often required to operate on electrical infrastructure, within Multiple Dwelling Units (MDUs). MDUs are owned by Building Network Operators (BNOs). DNOs and MOPs are requesting the Alt HAN Company to share their inventory information, for the benefit of all Parties.
