SEC v45.0 released to implement MP161

1 September 2021

An updated version of the SEC came into effect on 1 September 2021 to implement MP161 ‘Significant Code Review – Retail Code Consolidation’.

This is an Authority-Led Variation raised as part of the Significant Code Review (SCR) for Retail Code Consolidation.

This modification amends a number of refences to other Energy Codes alongside the SCR to ensure consistency between all the impacted Codes.

Additionally, it will introduce a new framework for progressing cross-Code modifications. The amendments will require the SEC Panel to nominate representatives to a new Cross Code Steering Group who will help coordinate and progress cross-Code issues. It also sets out the concept of Lead Codes and Consequential Changes and allows the Panel to appeal decisions on such changes to the Authority where appropriate. The intent is to ensure better coordination of cross-Code issues and the progression of related changes as a suite rather than piecemeal and staggered change.

 

What parts of the SEC were affected?

The following part of the SEC was affected:

  • Section A ‘Definitions and Interpretation’
  • Section B ‘Accession’
  • Section D ‘Modification Process’
  • Section E ‘Registration Data’
  • Section K ‘Charging Methodology’
  • Schedule 5 ‘Accession Information’
  • Appendix X ‘Registration Data Interface Specification’
  • Appendix Y ‘Registration Data Interface Code of Connection’

SEC v40.0 published for the June 2021 SEC Release

24 June 2021

SEC version 40.0 came into effect on 24 June 2021 to implement the June 2021 SEC Release. This included five Modification Proposals:

 

Summary of changes

MP106 will insert guidance in SEC Appendix I ‘CH Installation and Maintenance Support Materials’ showing that a response to Service Request 12.1 ‘Request WAN Matrix’ of “ “ (Space) should be interpreted as “Unknown”.

MP144 will amend the charging for Random Sample Privacy assessments so the Other User is charged, rather than it being spread across all DCC Users.

MP146 will remove the date ‘1 January 2021’ from SEC Section H8.16 to futureproof the SEC for Suppliers to continue to provide a service to areas where Wide Area Network (WAN) coverage is yet to be installed.

MP147 will amend the frequency for which the DCC must produce full Smart Metering Key Infrastructure (SMKI) extract, from a daily to a weekly basis.

MP153 will amend Section J1.2(b) so that the DCC only has to provide a separate invoice for Communications Hub Finance Charges if that is what is required under the direct agreement with the Approved Finance Party.

 

Implementation of the SECMP0007 CTSD legal text

The SEC Appendix R ‘Common Test Scenarios Document’ (CTSD) legal text under SECMP0007 ‘Firmware updates to IHDs and PPMIDs’ has also been implemented.

This follows on from the Authority’s approval to bring the CTSD changes under SECMP0007 forward from the November 2021 SEC Release to the June 2021 SEC Release.

More information including the rationale can be found here.

 

What parts of the SEC were affected?

3 April 2020

Proposal to move the June 2020 SEC Release implementation date – are you affected?

9 March 2020

The DCC is proposing that the implementation date for the June 2020 SEC Release is brought forward from 25 June 2020 to 6 May 2020. To help inform the Panel’s decision, we are seeking information on whether this date change would adversely impact you.

Further information on this release, including the current scope and the latest version of the Release Implementation Document, can be found on our June 2020 SEC Release webpage.

If you would be impacted by this change of date or have any comments on the DCC’s proposal, please contact us at sec.change@gemserv.com by close of play on Thursday, 12 March 2020. The Panel will be notified of any comments received when it considers the DCC’s request on Friday, 13 March 2020.

 

Why does the DCC want to bring this date forward?

The primary driver for the DCC seeking to bring the go-live date forward is that the SMETS1 Middle Operating Capability (MOC) release currently occupies the June 2020 SEC Release slot. Having considered a number of delivery options, and the importance of SECMP0062 ‘Northbound Application Traffic Management – Alert Storm Protection’ part 1, the DCC has identified that a revised go-live date of 6 May 2020 is the preferred option. This revised date also provides an improved risk profile to deliver SECMP0053 ‘Amend Target Response Times for Service Requests Critical to Installation and Commissioning Processes’ and SECMP0062 part 1.

The SMETS1 Core 1.1 release is currently planned to use the DCC’s testing environment before the SMETS1 MOC release in June. Attempting to deliver the SEC Release in-between these two releases would add significant risk for the SEC Release. Any slippage in the delivery of SMETS1 Core 1.1 would result in the June 2020 SEC Release being cancelled, as MOC delivery cannot be put at risk.

Combining the System Integration Testing (SIT), User Integration Testing (UIT), and Go-Live timelines for the SMETS1 Core 1.1 release and the SEC Release allows for the timely delivery of both releases, well in advance of the SMETS1 MOC delivery in June.

Bringing forward the SEC Release go-live date will also allow the SECMP0062 solution to be implemented earlier than currently planned, while also mitigating the risk of a delay to its delivery. The DCC highlights that any slippage to the delivery of SECMP0062 would expose the industry to the risks related to Alert Storms highlighted under this modification.
