DCC Customers are invited to DCC’s online workshop on 11 October 2021

SEC Parties are invited to join a two hour workshop in the afternoon on 11 October 2021 to capture your views on a new methodology the DCC is producing on Device Selection. The Device Selection Methodology aims to ensure that the DCC uses appropriate and manageable volumes of Devices in testing, and will initially be intended for use in the Network Evolution Communication Hubs and Networks.


Your input will directly shape the methodology. The workshop will cover:

1. An overview of the Device Selection Methodology criteria as currently suggested;
2. A discussion of what rules may apply to the methodology; and
3. A discussion to determine whether there should be additional considerations for Device Selection.

Please register your interest by emailing We look forward to you joining.

Rising energy prices, how SECAS and the DCC can support you

Increasing energy prices over the last six months has contributed to six Energy Suppliers ceasing to trade in the last three weeks. With more expected to follow, SECAS recognises that SEC Parties are facing numerous challenges and need clear guidance now more than ever.


If you have concerns, SECAS encourages you to contact the SECAS Helpdesk, or your relevant SEC Panel representative, who will support you in any way possible. For any DCC payment and invoice queries, please contact the DCC Customer Invoices Team (noting that payment terms remain the same).


You are also invited to share how you think we can help appointed Suppliers through the Supplier of Last Resort (SoLR) process. SECAS is currently drafting a guidance document and checklist for the SoLR process to help ensure that every step is clear and undertaken in a timely manner.


Take a look at this BEIS document which provides further information on the cause and actions to protect industry and supply here. Small Suppliers are encouraged to contact the SECAS Helpdesk to sign up to the monthly Small Supplier engagement call where you can discuss concerns and share feedback with your Panel representatives. The next meeting will take place on 20 October 2021.


Contribute to the SMDA Scheme Scope Review Consultation by 1 October 2021

The Smart Meter Device Assurance (SMDA) Scheme invites your feedback on the following:

  • Proposed changes to the scope of testing suggested by Network Operators for an Electricity Smart Meter Equipment (ESME);
  • Communications Hubs testing;
  • Interest in add-on validation services provided by the SMDA Test House; and
  • Whether further changes to the scope of the SMDA Scheme are required and if so, what these changes should be and the benefits that they would bring.


To respond to the consultation document, SEC Parties should fill in the response template and send it to the SMDA Team by 5pm on 1 October 2021. If you have any questions, please contact


View the new Version of the SMKI Recovery Key Guidance

SEC Parties are invited to read the updated Smart Metering Key Infrastructure Recovery Key Guidance (v1.3), which was approved at the September 2021 SMKI Policy Management Authority (PMA) meeting.


The document now more explicitly recognises what the SMKI PMA may consider in deciding whether to require the use of the SMKI Recovery Private Key or the Contingency Private Key (including the Contingency Symmetric Key). For more information, and to access the document, please click here. If you have any questions, please contact the SECAS Helpdesk.


SECAS welcomes SEC Panel and Sub-Committee Members to begin their term

The 2021 SEC Panel and Operations Group elections have now concluded. Thank you to all Parties who submitted a nomination and participated in voting! We welcome the following Members to represent your Party category and look forward to working with them over the coming two years. If you have any feedback on the Panel election process, please contact the SECAS Helpdesk.

If you would like to nominate yourself or an individual for any of the vacant Operations Group seats, please contact the SECAS Helpdesk.


New Draft Proposals

Four new Draft Proposals have been raised since the last newsletter. You are invited to provide feedback to the Change Team to help us understand whether these affect your Party.



DP181 ‘Meter Asset Provider access to asset related data held by the DCC’





The DCC holds the Smart Meter Inventory (SMI) which is a database of Devices that records Smart Meter Device data, which Suppliers can provide data to.

Meter Asset Providers (MAPs) wish to access SMI data to assess and manage the health of any smart assets they own. The data items that MAPs wish to access relate only to the metering asset and not the Responsible Supplier using the asset.

MAPs have requested that the DCC provides a data service fully paid for by the MAPs using the service, such that there will be no cost implications for DCC Users.



DP182 ‘Improving Transparency of Election Results’


In a SEC Panel or Sub-Committee election, there are sometimes more candidate nominations received than the seats available in that SEC Party Category. SEC Parties in that category are invited to vote for their preferred candidate, and the outcome of this vote is published, without the detailed breakdown of votes.

The proposer believes that publishing the breakdown of votes would increase transparency and encourage more engagement and participation from SEC Parties.



DP183 ‘Post Commissioning Obligations’


The DCC is required to provide several reports on failures in the Smart Metering Equipment Technical Specifications (SMETS) 2+ Post Commissioning process to multiple Industry Parties. However, some failures have occurred in the Post Commissioning process whereby a Device that has been successfully Commissioned, could be defined as having failed under the current criteria set out in the SEC.

Failures in the Post Commissioning process are therefore being over-reported to a significant degree, resulting in time and resources being wasted on ‘false positive’ cases and diverting focus from genuine issues.



DP184 ‘Increase Smart Capability of SMETS2 Twin Element ESME to support Solar and Storage use cases’


Twin element meters have two terminals. This enables the independent measurement of energy from two circuits (import and export) which is needed to calculate net energy consumption.

Currently, twin element meters only provide consumption data as a combined value across both phases. Therefore, tariffs cannot be applied to individual phase data. Although some electricity meters support measurement of each phase, the SEC and DCC systems do not currently support functionality allowing individual phase data to be retrieved.


Requests for Information

There are currently two Requests for Information (RFIs) out for consultation. You are invited to provide feedback to the Change Team to help us understand the scale of the issue, and to help scope a solution for the benefit of SEC Parties.



SECMP0010 ‘Introduction of triage arrangements for Communication Hubs’


Download the consultation here


Closing Date:

24 September 2021


If a Communications Hub installation fails, the installing Supplier sends it back to the Communications Service Provider (CSP). If the CSP does not find a fault with the Communications Hub, the Supplier is charged a fee. Only some are found to be genuinely faulty.

The current solution involves the development of a Hand-Held Terminal (HHT) that the Supplier can use to send commands to an unsuccessfully installed Communications Hub, allowing them to run diagnostics and to reset the Communications Hub if required. An alternative solution is being investigated due to the high cost of the described solution.



MP102B ‘Power Outage Alerts triggered by an OTA firmware upgrade – enduring solution’


Download the consultation here


Closing Date:

12 October 2021


Over the Air (OTA) firmware updates on some Electricity Smart Metering Equipment (ESMEs) cause an interruption to the Communications Hub for more than three minutes and therefore generate a Power Outage Alert (POA). This Alert is sent to the relevant Distribution Network Operator (DNO), who cannot determine whether the POA relates to a genuine power outage or an OTA firmware update.

It is understood that approximately 1.4m currently installed ESMEs could cause this issue. Suppliers are requested to provide insight to help refine the solution.
